spring cloud gateway modify response headers

The following example configures a header route predicate: This route matches if the request has a header named X-Request-Id whose value matches the \d+ regular expression (that is, it has a value of one or more digits). It supports basic downstream HTTP exchanges through methods that mirror the HTTP verbs. The RequestRateLimiter GatewayFilter factory uses a RateLimiter implementation to determine if the current request is allowed to proceed. You can add headers to the downstream response by using the header() methods on ProxyExchange. name can contain a space-separated list of header names. The predicates defined by RouteDefinitionLocator beans are combined using logical and. You can overwrite the names of the headers in the configuration by setting the values of the following arguments (shown with their default values): executionExceptionTypeHeaderName ("Execution-Exception-Type"), executionExceptionMessageHeaderName ("Execution-Exception-Message"), rootCauseExceptionTypeHeaderName ("Root-Cause-Exception-Type"), rootCauseExceptionMessageHeaderName ("Root-Cause-Exception-Message"). Add a response header named X-Request-Foo with a value of Bar to the original response. It is possible to create a gateway filter named without the. }) The following example configures an AddRequestParameter GatewayFilter: This will add red=blue to the downstream requests query string for all matching requests. This is the number of tokens the token bucket can hold. You can also manipulate response headers (and anything else you like in the response) by adding a mapper to the get() method (and other methods). The following diagram provides a high-level overview of how Spring Cloud Gateway works: Clients make requests to Spring Cloud Gateway. NEVER_STRIP: The version is not stripped, even if the original request path contains no version. It should be available as a GitHub (or similar) project or attached to this issue as a zip file. Spring Cloud Gateway Response Modification Raw README.md Overview As of this writing, there's a somewhat limited/restrictive means of applying HTTP response transformations/modifications via Spring Cloud Gateway, probably because it needs to accommodate both the Mono and Flux (aka "reactive") models. This appendix provides a list of common Spring Cloud Gateway properties and references to the underlying classes that consume them. 25Modify Response Body GatewayFilter Factory; It accepts the first parameter to override the time to expire a cache entry (expressed in s for seconds, m for minutes, and h for hours) and a second parameter to set the maximum size of the cache to evict entries for this route (KB, MB, or GB). It adds the Host header, scheme and port of the current request to any existing Forwarded header. Well occasionally send you account related emails. API gateway provides a unified access for services in microservices architecture. essentially skipping the filter. Spring Cloud CircuitBreaker supports multiple libraries that can be used with Spring Cloud Gateway. You can configure the gateway to create routes based on services registered with a DiscoveryClient compatible service registry. You can load-balance websockets by prefixing the URI with lb, such as lb:ws://serviceid. You can configure these timeouts can be configured (defaults shown) as follows: Configuration for Spring Cloud Gateway is driven by a collection of RouteDefinitionLocator instances. If the Gateway Handler Mapping determines that a request matches a route, it is sent to the Gateway Web Handler. Let's simplify this scenario. Create a ClientResponse object that will hold both the body and the headers: Then extract the body and encrypt it using the EncryptDecryptHelper class. It is the name of the header to be removed. Configuring Predicates and Filters For, 15.4. method: Method name in the service that handles the request. If the URI has a scheme prefix, such as lb:ws://serviceid, the lb scheme is stripped from the URI and placed in the ServerWebExchangeUtils.GATEWAY_SCHEME_PREFIX_ATTR for use later in the filter chain. The following example configures a method route predicate: This route matches if the request method was a GET or a POST. Spring Cloud Gateway - read response body and set response headers Ask Question Asked 1 year, 11 months ago Modified 1 year, 11 months ago Viewed 675 times 0 I want to implement a GatewayFilter that reads the response body and out of this the response code is determined and should then be set afterwards. You can read more about them in the. The following listing configures a RewriteLocationResponseHeader GatewayFilter: For example, for a request of POST api.example.com/some/object/name, the Location response header value of object-service.prod.example.net/v2/some/object/id is rewritten as api.example.com/some/object/id. extracts an access token from the currently authenticated user, AddRequestHeader is aware of the URI variables used to match a path or host. In Puma (RubyGem) before 4.3.3 and 3.12.4, if an application using Puma allows untrusted input in an early-hints header, an attacker can use a carriage return character to end the header and inject malicious content, such as additional headers or an entirely new response body. Currently, only forward: schemed URIs are supported. The RemoveRequestParameter GatewayFilter factory takes a name parameter. Building a Simple Gateway by Using Spring MVC or Webflux, FallbackHeaders GatewayFilter Factory section, Spring Cloud CircuitBreaker Factory section, object-service.prod.example.net/v2/some/object/id, Retrieving Information about a Particular Route. The default is http|https|ftp|ftps. When communicating over HTTPS, the client initiates a TLS handshake. The hostValue parameter, if provided, is used to replace the host:port portion of the response Location header. In subsequent calls, this value is recalculated with the number of seconds left until the response expires. It may be the integer value 404 or the string representation of the enumeration: NOT_FOUND. The path part of the request URL is overridden with the path in the forward URL. If it is not provided, the value of the Host request header is used. The following example configures an AddResponseHeader GatewayFilter: This adds X-Response-Red:Blue header to the downstream responses headers for all matching requests. This filter also automatically calculates the. Already on GitHub? Usually it's a common requirement that applications can . This filter works only with HTTP (including HTTPS) requests. return r.host("*.somehost.org").and().path("/somepath") Post global filters are usually used in spring cloud gateway to perform operations on response like adding some headers or modifying response body or response status etc. Most examples below use the shortcut way. The Retry GatewayFilter factory supports the following parameters: retries: The number of retries that should be attempted. This uses the URI templates from Spring Framework. .route("test1", r -> { The earlier configuration examples all use a shortcut notation that uses positional arguments rather than named ones. The following listing configures a Retry GatewayFilter: A simplified "shortcut" notation can be added with a single status and method. The following example configures such a fallback: The following listing does the same thing in Java: This example forwards to the /inCaseofFailureUseThis URI when the circuit breaker fallback is called. The following example configures a RemoteAddr route predicate: This route matches if the remote address of the request was, for example, 192.168.1.10. Looking for a place to stay in Gunzenhausen? First-class support is provided for sensitive headers (by default, cookie and authorization), which are not passed downstream, and for proxy (x-forwarded-*) headers. This approach is vulnerable to spoofing, as a malicious client could set an initial value for the X-Forwarded-For, which would be accepted by the resolver. Response data is not cached if Cache-Control header does not allow it (no-store present in the request or no-store or private present in the response). You can use the CacheRequestBody filter to cache the request body before sending it downstream and getting the body from exchange attribute. This metric will be available from /actuator/metrics/spring.cloud.gateway.routes.count. This is useful when you try to support CORS preflight requests and your route predicate does not evaluate to true because the HTTP method is options. The default implementation of KeyResolver is the PrincipalNameKeyResolver, which retrieves the Principal from the ServerWebExchange and calls Principal.getName(). /resource). if you intend to modify a JSON response body prior to returning to the client, the above gist will not work (i know because i tried). The lowercase full name of the secure header needs to be used to disable it.. By clicking Sign up for GitHub, you agree to our terms of service and The following example configures a XForwardedRemoteAddr route predicate: This route matches if the X-Forwarded-For header contains, for example, 192.168.1.10. This predicate extracts the URI template variables (such as segment, defined in the preceding example) as a map of names and values and places it in the ServerWebExchange.getAttributes() with a key defined in ServerWebExchangeUtils.URI_TEMPLATE_VARIABLES_ATTRIBUTE. We've already covered its basic usage in earlier tutorials, so we won't get into those aspects here. There are convenience methods that you can use to mark an exchange as routed . The following example shows how to achieve the same configuration with Java: The Weight route predicate factory takes two arguments: group and weight (an int). I got the root cause. If none of these parameters are configured but the global filter is enabled, by default, it configures 5 minutes of time to live for the cached response. The Path Route Predicate Factory takes two parameters: a list of Spring PathMatcher patterns and an optional flag called matchTrailingSlash (defaults to true). import static org.springframework.cloud.gateway.support.RouteMetadataUtils.CONNECT_TIMEOUT_ATTR; The RemoveHopByHop Headers Filter removes headers from forwarded requests. The pattern is an Ant-style pattern with . The following example configures a weight route predicate: This route would forward ~80% of traffic to weighthigh.org and ~20% of traffic to weighlow.org. A route is matched if the aggregate predicate is true. It uses the Netty HttpClient to make the downstream proxy request. For example, given a Gateway that has 1 replica, the following will . The following listing configures a RemoveRequestHeader GatewayFilter: This removes the X-Request-Foo header before it is sent downstream. As Spring Cloud Gateway distinguishes between pre and post phases for filter logic execution (see How it Works), the filter with the highest precedence is the first in the pre-phase and the last in the post-phase. Because Spring-Cloud-Gateway is a responsive architecture design based on WebFlux, traditional programming ideas are not suitable for the development of Reactor Stream in the process of migrating from Zuul. Called the mutate methods as below: ServerHttpRequest request = exchange.getRequest () .mutate () .header ("headerkey", jwt) .build (); exchange.mutate ().request (request).build (); return chain.filter (exchange); However, the header is not injected to the backend api. Spring Cloud has it's own way of defining Feign clients, it's done with Spring MVC annotations. The following example configures a KeyResolver in Java: This defines a request rate limit of 10 per user. It uses the Spring WebSocket infrastructure to forward the websocket request downstream. Multiple matching segments are allowed. How does it work? If the URL has a lb scheme (such as lb://myservice), it uses the Spring Cloud ReactorLoadBalancer to resolve the name (myservice in this example) to an actual host and port and replaces the URI in the same attribute. It is the name of the header to be removed. also note that the gist doesn't take the decoders into account from upstream like here. The following listing defines a rate limiter that uses the KeyResolver defined in the previous listing: The RewriteLocationResponseHeader GatewayFilter factory modifies the value of the Location response header, usually to get rid of backend-specific details. This predicate matches requests that happen before the specified datetime. Star 14. Sumant Rana 77 Followers Embark on a cloud native journey Follow More from Medium URI variables may be used in the value and will be expanded at runtime. The following listing shows the definition of the RouteDefinitionLocator interface: By default, a PropertiesRouteDefinitionLocator loads properties by using Spring Boots @ConfigurationProperties mechanism. Each item defines the name and the arguments of a given predicate. If it is not, a status of HTTP 429 - Too Many Requests (by default) is returned. The status parameter should be a 300 series redirect HTTP code, such as 301. If the new named header already exists, its values are augmented with the new values. Both offer the same possibilities. This paper will introduce its usage in detail. It runs after all other filters have completed and writes the proxy response back to the gateway client response. URI variables may be used in the value and will be expanded at runtime. The following example configures a DedupeResponseHeader GatewayFilter: This removes duplicate values of Access-Control-Allow-Credentials and Access-Control-Allow-Origin response headers in cases when both the gateway CORS logic and the downstream logic add them. While a Gateway is running you can use kubectl scale to modify the number of replicas. The parts parameter indicates the number of parts in the path to strip from the request before sending it downstream. .metadata(RESPONSE_TIMEOUT_ATTR, 200) The Forwarded Headers Filter creates a Forwarded header to send to the downstream service. For each factory there is a string representation of the corresponding object (for example, [[emailprotected] configClass = Object]). SetResponseHeader is aware of URI variables used to match a path or host. Code Revisions 1 Stars 14 Forks 3. To use the ProxyExchange, include the right module in your classpath (either spring-cloud-gateway-mvc or spring-cloud-gateway-webflux). The following example configures a SaveSession GatewayFilter: If you integrate Spring Security with Spring Session and want to ensure security details have been forwarded to the remote process, this is critical. Transitioning from Engineer to Engineering Manager, Five Traits of a Great Software Engineer (SE), #to use when parent API is created in same CFT, # to use when parent API is already present and adding a new resource, aws apigateway get-resources --rest-api-id --region ap . Filter: These are instances of GatewayFilter that have been constructed with a specific factory. {githubmaster}/src/main/java/org/springframework/cloud/gateway/security/TokenRelayGatewayFilterFactory.java[filter] ServerWebExchangeUtils.setAlreadyRouted takes a ServerWebExchange object and marks it as routed. In order to modify APIcast behavior with custom policies, you must do the following: Add custom policies to APIcast Define a policy chain that configures APIcast policies Add the policy chain to APIcast 4.1. So a request to /hello is sent to /mypath/hello. Spring Cloud Gateway includes many built-in GatewayFilter Factories. - thaneesh shanand Apr 16, 2018 at 1:05 If the fallback is called, the request is forwarded to the controller matched by the URI. For example, when we use Spring Cloud Gateway to implement the gateway, we need to implement a function: parse the JWT stored in the request header, extract the user ID in it, and then write it to the request body. The following example configures an AddRequestHeader GatewayFilter that uses a variable: The AddRequestHeadersIfNotPresent GatewayFilter factory takes a collection of name and value pairs separated by colon. To retrieve information about a single route, make a GET request to /actuator/gateway/routes/{id} (for example, /actuator/gateway/routes/first_route). .filters(f -> f.addRequestHeader("header1", "header-value-1")) public RouteLocator customRouteLocator(RouteLocatorBuilder routeBuilder){ Download ZIP. Cleanliness 4.4. The redis-rate-limiter.requestedTokens property is how many tokens a request costs. To retrieve the routes defined in the gateway, make a GET request to /actuator/gateway/routes. To enable wiretap, set spring.cloud.gateway.httpserver.wiretap=true or spring.cloud.gateway.httpclient.wiretap=true for the HttpServer and HttpClient, respectively. The datetime2 parameter must be after datetime1. The JSONToGRPCFilter GatewayFilter Factory converts a JSON payload to a gRPC request. Spring Cloud supports Resilience4J out of the box. The following example configures an after route predicate: This route matches any request made after Jan 20, 2017 17:42 Mountain Time (Denver). The following listing configures a websocket routing filter: After the gateway has routed a ServerWebExchange, it marks that exchange as routed by adding gatewayAlreadyRouted The Gateway is defined with a number of routes, each with Predicates to match the request to the route. If you would like us to look at this issue, please provide the requested information and we will re-open the issue. Retrieving the Routes Defined in the Gateway, 15.5. For more detailed examples of how to use any of the following filters, take a look at the. The following two examples are equivalent: For some usages of the gateway, properties are adequate, but some production use cases benefit from loading configuration from an external source, such as a database. AddRequestParameter is aware of the URI variables used to match a path or host. However, you can customize this TrustManager by creating a bean of type GrpcSslConfigurer: This filter allows caching the response body and headers to follow these rules: It caches the response only for one of the following status codes: HTTP 200 (OK), HTTP 206 (Partial Content), or HTTP 301 (Moved Permanently). The following example configures an RemoveJsonAttributesResponseBody GatewayFilter: This removes attributes "id" and "color" from the JSON content body at root level. The following example configures a query route predicate: The preceding route matches if the request contained a green query parameter. This route predicate allows requests to be filtered based on the X-Forwarded-For HTTP header. Future milestone versions will have RouteDefinitionLocator implementations based off of Spring Data Repositories, such as Redis, MongoDB, and Cassandra. There are two ways to configure predicates and filters: shortcuts and fully expanded arguments. This is the rate at which the token bucket is filled. This predicate matches cookies that have the given name and whose values match the regular expression. The Netty routing filter runs if the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a http or https scheme. The following listing shows how it works: This style also allows for more custom predicate assertions. The HTTP Cache-Control header allows caching (that means it does not have any of the following values: no-store present in the request and no-store or private present in the response). The first step is to create a ServerHttpResponseDecorator object and override the writeWith method. These are basic guides to writing some custom components of the gateway. The following describes an alternative style gateway. exceptions: A list of thrown exceptions that should be retried. The following example configures a host route predicate: URI template variables (such as {sub}.myhost.org) are supported as well. Refresh the page, check Medium 's site status, or find something interesting to read. The response is put in the ServerWebExchangeUtils.CLIENT_RESPONSE_ATTR exchange attribute for use in a later filter. Likewise to the RedisRateLimiter Filter Factory it requires the use of the spring-boot-starter-data-redis-reactive Spring Boot starter. This filter adds a timer metric named spring.cloud.gateway.requests with the following tags: routeUri: The URI to which the API is routed. There is an abstract class called AbstractRoutePredicateFactory which you can extend. There are many caching cases on the network, but there are various Bug problems in the testing process. methods: The HTTP methods that should be retried, represented by using org.springframework.http.HttpMethod. The ServerHttpResponse instance is used to . 3,AddResponseHeader GatewayFilter Factory. The following listing configures a SetRequestHostHeader GatewayFilter: The SetRequestHostHeader GatewayFilter factory replaces the value of the host header with example.org. This interface and its usage are subject to change in future milestone releases. (There is also an experimental WebClientHttpRoutingFilter that performs the same function but does not require Netty. This handler runs the request through a filter chain that is specific to the request. Spring Cloud Gateway aims to provide a simple, yet effective way to route to APIs and provide cross cutting concerns to them such as: security, monitoring/metrics, and resiliency. #{@myKeyResolver} is a SpEL expression that references a bean named myKeyResolver. Retries are performed after a backoff interval of firstBackoff * (factor ^ n), where n is the iteration. Fork 3. .build(); To clear the routes cache, make a POST request to /actuator/gateway/refresh. The following listing configures a SetResponseHeader GatewayFilter: This GatewayFilter replaces (rather than adding) all headers with the given name. By default, the gateway defines a single predicate and filter for routes created with a DiscoveryClient. For the external controller/handler scenario, headers can be added with exception details. The resulting response is similar to the following: The response contains the details of the GatewayFilter factories applied to any particular route. The following MVC example proxies a request to /test downstream to a remote server: The following example does the same thing with Webflux: Convenience methods on the ProxyExchange enable the handler method to discover and enhance the URI path of the incoming request. The The following example shows what this looks like: To enable Reactor Netty access logs, set -Dreactor.netty.http.server.accessLogEnabled=true. This combined filter chain is sorted by the org.springframework.core.Ordered interface, which you can set by implementing the getOrder() method. Zuul profile. For relative redirects, you should use uri: no://op as the uri of your route definition. to the exchange attributes. per-route http timeouts configuration via configuration, per-route timeouts configuration using Java DSL, Example 73. When combined with setting the reactor.netty log level to DEBUG or TRACE, it enables the logging of information, such as headers and bodies sent and received across the wire. This is the number of tokens taken from the bucket for each request and defaults to 1. If the information is not provided within the next 7 days this issue will be closed. The RemoveResponseHeader GatewayFilter factory takes a name parameter. Have a question about this project? Spring Cloud Gateway aims to provide a simple, yet effective way to route to APIs and provide cross cutting concerns to them such as: security, monitoring/metrics, and resiliency. If so, the same rules apply. You can adjust this behavior by setting the spring.cloud.gateway.filter.request-rate-limiter.deny-empty-key (true or false) and spring.cloud.gateway.filter.request-rate-limiter.empty-key-status-code properties. By default, it creates a NettyChannel by using the default TrustManagerFactory. The FallbackHeaders factory lets you add Spring Cloud CircuitBreaker execution exception details in the headers of a request forwarded to a fallbackUri in an external application, as in the following scenario: In this example, after an execution exception occurs while running the circuit breaker, the request is forwarded to the fallback endpoint or handler in an application running on localhost:9994. To see the list of all Spring Cloud Gateway related configuration properties, see the appendix. When setting the That is not a complete working sample, it is just some code. .uri("http://someuri") GatewaySampleApplication.java. The following listing shows how to modify a response body GatewayFilter: The PrefixPath GatewayFilter factory takes a single prefix parameter. keyResolver is a bean that implements the KeyResolver interface. In some cases you might want to trip a circuit breaker based on the status code The following example shows how to do so: The SetPath GatewayFilter factory takes a path template parameter. In a new folder, download and extract a new Spring Cloud Gateway project using start.spring.io(and HTTPie) as follows. and puts it in a request header for the downstream requests. If matchTrailingSlash is set to false, then request path /red/1/ will not be matched. This predicate matches requests that happen after the specified datetime. The following examples show how to do so: Custom filters class names should end in GatewayFilterFactory. The following example configures /actuator/gateway/routes: This feature is enabled by default. Naming Custom Filters And References In Configuration, 18. This is the value of the Location header. The Netty routing filter runs if the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a http or https scheme. The filter takes a host parameter. URI variables may be used in the value and are expanded at runtime. If you are routing to an HTTPS backend, you can configure the gateway to trust all downstream certificates with the following configuration: Using an insecure trust manager is not suitable for production. The name and argument names are listed as code in the first sentence or two of each section. Creating of individual headers can be controlled by the following boolean properties (defaults to true): spring.cloud.gateway.x-forwarded.for-enabled, spring.cloud.gateway.x-forwarded.host-enabled, spring.cloud.gateway.x-forwarded.port-enabled, spring.cloud.gateway.x-forwarded.proto-enabled, spring.cloud.gateway.x-forwarded.prefix-enabled. Getting the refreshTokenMono is webclient call which is in a different service.. By the time it gives the response, main response is already about to commit and wont allow us to modify the response headers. You can configure Spring Cloud Gateway for Kubernetes to run multiple instances in High Availability as you would do with a normal Kubernetes resource. If you want to customize the predicates or filters used by the DiscoveryClient routes, set spring.cloud.gateway.discovery.locator.predicates[x] and spring.cloud.gateway.discovery.locator.filters[y]. Am I doing it wrong? The RemoteAddr Route Predicate Factory, 5.10.1. A per-route response-timeout with a negative value will disable the global response-timeout value. To retrieve the GatewayFilter factories applied to routes, make a GET request to /actuator/gateway/routefilters. return routeBuilder.routes() In addition, you can configure this filter once by using spring.cloud.gateway.default-filters and have it applied to all routes. response-timeout must be specified as a java.time.Duration. . In order to share Routes across a cluster of Spring Cloud Gateway instances, RedisRouteDefinitionRepository can be used. The default request size is set to five MB if not provided as a filter argument in the route definition. The following listing configures a redis-rate-limiter: Rate limits below 1 request/s are accomplished by setting replenishRate to the wanted number of requests, requestedTokens to the timespan in seconds, and burstCapacity to the product of replenishRate and requestedTokens. URIs defined in routes without a port get default port values of 80 and 443 for the HTTP and HTTPS URIs, respectively. This lets you match on anything from the HTTP request, such as headers or parameters. The XForwarded Headers Filter creates various X-Forwarded-* headers to send to the downstream service. *) and the replacement /${remaining}. The RemoveJsonAttributesResponseBody GatewayFilter factory takes a collection of attribute names to search for, an optional last parameter from the list can be a boolean to remove the attributes just at root level (thats the default value if not present at the end of the parameter configuration, false) or recursively (true). Spring Cloud Gateway comes with one non-default remote address resolver that is based off of the X-Forwarded-For header, XForwardedRemoteAddressResolver. connect-timeout must be specified in milliseconds. You can extend an abstract class called AbstractGatewayFilterFactory. 1. Retrieving Information about a Particular Route, 15.6. The algorithm used is the Token Bucket Algorithm.
