spring cloud gateway modify response headers

With MVC, it also supports forwarding to a local handler through the forward() method. It is the name of the header to be removed. Appending multiple headers can be controlled by the following boolean properties (defaults to true): spring.cloud.gateway.x-forwarded.for-append, spring.cloud.gateway.x-forwarded.host-append, spring.cloud.gateway.x-forwarded.port-append, spring.cloud.gateway.x-forwarded.proto-append, spring.cloud.gateway.x-forwarded.prefix-append. Httpbin.org - a website and diagnosis tool which converts Http GET request data into a JSON response; Step 1: Create a project. In addition, you can configure this filter once by using spring.cloud.gateway.default-filters and have it applied to all routes. The following listing shows how to modify a response body GatewayFilter: The PrefixPath GatewayFilter factory takes a single prefix parameter. The following example shows such an errorMessage: There are certain situation when the host header may need to be overridden. XForwardedRemoteAddressResolver::maxTrustedIndex takes an index that correlates to the number of trusted infrastructure running in front of Spring Cloud Gateway. Options. The following example creates a Logback configuration: You can configure the gateway to control CORS behavior globally or per route. It is a Spring Boot application with Spring Cloud stuff that can make it sit between clients and their requests and multiple services, where it offers features such as predicates for shaping. This predicate matches requests that happen before the specified datetime. keyResolver is a bean that implements the KeyResolver interface. 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. In future milestone releases, there will be some KeyResolver implementations. The first one is the The following example shows how to do so: You can route gateway routes to both HTTP and HTTPS backends. These are special filters that are conditionally applied to all routes. The following example configures an AddResponseHeader GatewayFilter: This adds X-Response-Red:Blue header to the downstream responses headers for all matching requests. In subsequent calls, this value is recalculated with the number of seconds left until the response expires. The Netty routing filter runs if the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a http or https scheme. CircuitBreaker also supports URI variables in the fallbackUri. Predicate: This is a Java 8 Function Predicate. #{@myKeyResolver} is a SpEL expression that references a bean named myKeyResolver. If the information is not provided within the next 7 days this issue will be closed. This can be used with reverse proxies such as load balancers or web application firewalls where Spring Cloud Gateway comes with one non-default remote address resolver that is based off of the X-Forwarded-For header, XForwardedRemoteAddressResolver. The maxSize is a DataSize type, so values can be defined as a number followed by an optional DataUnit suffix such as 'KB' or 'MB'. To remove any kind of sensitive header, you should configure this filter for any routes for which you may want to do so. The Between route predicate factory takes two parameters, datetime1 and datetime2 The protocolsRegex parameter must be a valid regex String, against which the protocol name is matched. Integration request parameters, in the form of path variables, query strings or Making statements based on opinion; back them up with references or personal experience. response-timeout must be specified in milliseconds. Spring Cloud has it's own way of defining Feign clients, it's done with Spring MVC annotations. 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). I too was experiencing the UnsupportedOperationException when I added a post filter to an existing global filter which had an order that caused the post filter to action to occur after the response had been sent. Removes an existing route from the gateway. When communicating over HTTPS, the client initiates a TLS handshake. You signed in with another tab or window. The global CORS configuration is a map of URL patterns to Spring Framework CorsConfiguration. The primary scenario is to use the fallbackUri to define an internal controller or handler within the gateway application. This predicate extracts the URI template variables (such as sub, 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. ServerWebExchangeUtils.setAlreadyRouted takes a ServerWebExchange object and marks it as routed. For example, setting replenishRate=1, requestedTokens=60, and burstCapacity=60 results in a limit of 1 request/min. You can configure the logging system to have a separate access log file. This predicate matches requests that happen after the specified datetime. If it is not matched, the filter does nothing. /resource). To change the default values, set the appropriate property in the spring.cloud.gateway.filter.secure-headers namespace. 4.1. Since 4.0.0, Spring Cloud Gateway supports Spring AOT transformations and native images. .metadata(CONNECT_TIMEOUT_ATTR, 200); Displays the list of GatewayFilter factories applied to a particular route. The following example configures a KeyResolver in Java: This defines a request rate limit of 10 per user. The following example configures a SetPath GatewayFilter: For a request path of /red/blue, this sets the path to /blue before making the downstream request. Spring Cloud Gateway. Fully expanded arguments appear more like standard yaml configuration with name/value pairs. APIcast standard policies The previous sample defines the Cookie Route Predicate Factory with two arguments, the cookie name, mycookie and the value to match mycookievalue. You can find more information on doing so in the FallbackHeaders GatewayFilter Factory section. This filter also automatically calculates the. By using the fluent Java API, you can use the and(), or(), and negate() operators on the Predicate class. I suppose your issue may have been different than mine, but when I turned on trace logging I saw that my filter was executing after the response was sent and so I gave the filter a different order value that put it in the right order. It must be a Java System Property, not a Spring Boot property. To create a route, make a POST request to /gateway/routes/{id_route_to_create} with a JSON body that specifies the fields of the route (see Retrieving Information about a Particular Route). A steady rate is accomplished by setting the same value in replenishRate and burstCapacity. per-route http timeouts configuration via configuration, per-route timeouts configuration using Java DSL, Example 73. Spring Cloud Gateway 1AddRequestHeader GatewayFilter Factory2AddRequestParameter GatewayFilter Factory3AddResponseHeader GatewayFilter Factory4DedupeResponseHeader GatewayFilter Fa. Here is a link to someone asking about ordered filters that may provide more insight: #1341. The resulting response is similar to the following: The response contains the details of the GatewayFilter factories applied to any particular route. This route predicate allows requests to be filtered based on the X-Forwarded-For HTTP header. method: Method name in the service that handles the request. This vulnerability is known as HTTP Response Splitting. You can load-balance websockets by prefixing the URI with lb, such as lb:ws://serviceid. The following example shows what this looks like: To enable Reactor Netty access logs, set -Dreactor.netty.http.server.accessLogEnabled=true. The redis-rate-limiter.replenishRate property defines how many requests per second to allow (without any dropped requests). Fork 3. The redis-rate-limiter.burstCapacity property is the maximum number of requests a user is allowed in a single second (without any dropped requests). connect-timeout must be specified in milliseconds. Then the proxy request is made. It does not work in a traditional Servlet Container or when built as a WAR. This filter works only with HTTP (including HTTPS) requests. The following listing configures a SetRequestHeader GatewayFilter: This GatewayFilter replaces (rather than adding) all headers with the given name. httpStatusCode: The HTTP Status of the request returned to the client. Then, by default, the gateway metrics filter runs as long as the spring.cloud.gateway.metrics.enabled property is not set to false. The RemoveRequestParameter GatewayFilter factory takes a name parameter. The name and argument names are listed as code in the first sentence or two of each section. Passing headers with Spring Cloud Feign. For the external controller/handler scenario, headers can be added with exception details. AS_IN_REQUEST: The version is stripped only if the original request path contains no version. a circuit breaker. If it is not, a status of HTTP 429 - Too Many Requests (by default) is returned. to the exchange attributes. ALWAYS_STRIP: The version is always stripped, even if the original request path contains version. In this situation, the SetRequestHostHeader GatewayFilter factory can replace the existing host header with a specified value. In configuration, reference the bean by name using SpEL. Well occasionally send you account related emails. essentially skipping the filter. 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"). 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. It uses Java regular expressions for a flexible way to rewrite the response header value. The default predicate is a path predicate defined with the pattern /serviceId/**, where serviceId is Spring Cloud Gateway includes many built-in route predicate factories. 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 runs after all other filters have completed and writes the proxy response back to the gateway client response. When setting the This uses Java regular expressions for a flexible way to rewrite the request path. Am I doing it wrong? The following listing configures a Retry GatewayFilter: A simplified "shortcut" notation can be added with a single status and method. The text was updated successfully, but these errors were encountered: Can you provide a complete, minimal, verifiable sample that reproduces the problem? The following example configures a MapRequestHeader: This adds the X-Request-Red: header to the downstream request with updated values from the incoming HTTP requests Blue header. https://github.com/spring-cloud/spring-cloud-gateway/blob/master/spring-cloud-gateway-core/src/main/java/org/springframework/cloud/gateway/filter/factory/SetResponseHeaderGatewayFilterFactory.java, @ryanjbaxter it seems a route filter,can i modify a response header in a global post filter,thanks. 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. The accepted values are RETAIN_FIRST (default), RETAIN_LAST, and RETAIN_UNIQUE. (There is also an experimental WebClientWriteResponseFilter that performs the same function but does not require Netty.). It is possible to create a gateway filter named without the. You can add headers to the downstream response by using the header() methods on ProxyExchange. If the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a ws or wss scheme, the websocket routing filter runs. 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 . If the response is already cached and a new request is performed with no-cache value in Cache-Control header, it returns a bodiless response with 304 (Not Modified). Raw. This appendix provides a list of common Spring Cloud Gateway properties and references to the underlying classes that consume them. Spring Cloud CircuitBreaker supports multiple libraries that can be used with Spring Cloud Gateway. So, if the downstream server responded with X-Request-Red:1234, it will be replaced with X-Request-Red:Blue, which is what the downstream service would receive. extracts an access token from the currently authenticated user, To configure per-route timeouts: ServerHttpResponse interface. If you would like us to look at this issue, please provide the requested information. }) The lowercase full name of the secure header needs to be used to disable it.. CacheRequestBody then places it in the attributes available from ServerWebExchange.getAttributes(), with a key defined in ServerWebExchangeUtils.CACHED_REQUEST_BODY_ATTR. Once matched, the Gateway executes pre-request logic on each of the filters applied to the route. The resulting response is similar to the following: The following table describes the structure of the response: The collection of route predicates. XForwardedRemoteAddressResolver has two static constructor methods, which take different approaches to security: XForwardedRemoteAddressResolver::trustAll returns a RemoteAddressResolver that always takes the first IP address found in the X-Forwarded-For header. The DedupeResponseHeader filter also accepts an optional strategy parameter. This filter sets a request attribute that the routing filter inspects to determine if the original host header should be sent rather than the host header determined by the HTTP client. Spring Cloud supports Resilience4J out of the box. Route filters allow the modification of the incoming HTTP request or outgoing HTTP response in some manner. spring.cloud.gateway.filter.local-response-cache.size: Sets the maximum size of the cache to evict entries for this route (in KB, MB and GB). 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. Those values are then available for use by GatewayFilter factories. Usually it's a common requirement that applications can . In case of the request being forwarded to fallback, the Spring Cloud CircuitBreaker Gateway filter also provides the Throwable that has caused it. 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. To write a custom global filter, you must implement GlobalFilter interface as a bean. Currently, only forward: schemed URIs are supported. If max-age is present on the original response, the value is rewritten with the number of seconds set in the timeToLive configuration parameter. series: The series of status codes to be retried, represented by using org.springframework.http.HttpStatus.Series. The default list of headers that is removed comes from the IETF. Multiple matching segments are allowed. See the Spring Cloud Project page for details on setting up your build system with the current Spring Cloud Release Train. 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. The PreserveHostHeader GatewayFilter factory has no parameters. The following loggers may contain valuable troubleshooting information at the DEBUG and TRACE levels: org.springframework.boot.autoconfigure.web. GatewaySampleApplication.java. The following table below summarizes the Spring Cloud Gateway actuator endpoints (note that each endpoint has /actuator/gateway as the base-path): Displays the list of global filters applied to the routes. 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 between route predicate: This route matches any request made after Jan 20, 2017 17:42 Mountain Time (Denver) and before Jan 21, 2017 17:42 Mountain Time (Denver). Note that this example also demonstrates the (optional) Spring Cloud LoadBalancer load-balancing (defined by the lb prefix on the destination URI). statuses: The HTTP status codes that should be retried, represented by using org.springframework.http.HttpStatus. 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. For example, given a Gateway that has 1 replica, the following will . outcome: The outcome, as classified by HttpStatus.Series. The redis-rate-limiter.requestedTokens property is how many tokens a request costs. The preceding route matches if the request contained a red query parameter whose value matched the gree. 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 RemoveRequestHeader GatewayFilter factory takes a name parameter. The following example configures a PrefixPath GatewayFilter: This prefixes /mypath to the path of all matching requests. This predicate matches with a header that has the given name whose value matches the regular expression. Easy to extend and/or customize using standard Spring patterns The route configuration allows applying CORS directly to a route as metadata with key cors. The following example configures an AddRequestParameter GatewayFilter that uses a variable: The AddResponseHeader GatewayFilter Factory takes a name and value parameter. If it is not provided, the value of the Host request header is used. It supports basic downstream HTTP exchanges through methods that mirror the HTTP verbs. forwards the incoming token to outgoing resource requests. This type of Repository is not suited to populate Routes across multiple Gateway instances. Spring Cloud Gateway can forward OAuth2 access tokens downstream to the services The RequestHeaderSize GatewayFilter factory takes maxSize and errorHeaderName parameters. The Host route predicate factory takes one parameter: a list of host name patterns. The RewriteResponseHeader GatewayFilter factory takes name, regexp, and replacement parameters. .uri("http://someuri") 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. If Spring Cloud Gateway is, for example only accessible through HAProxy, then a value of 1 should be used. 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. The Spring Cloud Gateway project is built on top of the popular Spring Boot 2 and Project Reactor, so it inherits its main treats: Low resource usage, thanks to its reactive nature Support for all goodies from the Spring Cloud ecosystem (discovery, configuration, etc.) The SecureHeaders GatewayFilter factory adds a number of headers to the response, per the recommendation made in this blog post. While a Gateway is running you can use kubectl scale to modify the number of replicas. The DedupeResponseHeader GatewayFilter factory takes a name parameter and an optional strategy parameter. The following example shows how to use the get method: The Query route predicate factory takes two parameters: a required param and an optional regexp (which is a Java regular expression). Service 4.3. The XForwarded Remote Addr Route Predicate Factory, 6.5.1. The default implementation of KeyResolver is the PrincipalNameKeyResolver, which retrieves the Principal from the ServerWebExchange and calls Principal.getName(). It adds the Host header, scheme and port of the current request to any existing Forwarded header. Spring Cloud Gateway requires the Netty runtime provided by Spring Boot and Spring Webflux. Typically, there will be a name key and an args key. By default, when a service instance cannot be found by the, Gateway supports all the LoadBalancer features. In the example below the call consumingServiceEndpoint/users/1 will be redirected to inCaseOfFailureUseThis/users/1. also note that the gist doesn't take the decoders into account from upstream like here. When doing so, you need to make sure to include the default predicate and filter shown earlier, if you want to retain that functionality. How to modify spring cloud gateway response headers, https://github.com/spring-cloud/spring-cloud-gateway/files/3244970/code.txt, https://github.com/spring-cloud/spring-cloud-gateway/blob/master/spring-cloud-gateway-core/src/main/java/org/springframework/cloud/gateway/filter/factory/SetResponseHeaderGatewayFilterFactory.java. The url parameter should be a valid URL. The following example configures an AddRequestHeadersIfNotPresent GatewayFilter that uses a variable: The AddRequestParameter GatewayFilter Factory takes a name and value parameter. Modifying the headers is simple because we can obtain a reference to the HttpHeaders map object: exchange.getRequest () .mutate () .headers (h -> h.setAcceptLanguageAsLocales ( Collections.singletonList (requestLocale))) Copy But, on the other hand, modifying the URI is not a trivial task. The RewritePath GatewayFilter factory takes a path regexp parameter and a replacement parameter. The following examples show how to do so: Custom filters class names should end in GatewayFilterFactory. return r.host("*.somehost.org").and().path("/somepath") It uses the Netty HttpClient to make the downstream proxy request. To retrieve information about a single route, make a GET request to /actuator/gateway/routes/{id} (for example, /actuator/gateway/routes/first_route). This is the value of the Location header. org.springframework.cloud.gateway.filter.factory.rewrite.ModifyResponseBodyGatewayFilterFactory body gzipchunkedHTTP Filter MonoFluxtry catch .just (xxx).doOnError () 2.2 You can enable, disable, or configure policies to control how they modify APIcast. Those values are then available for use by GatewayFilter factories. The ServerHttpResponse instance is used to . Tripping The Circuit Breaker On Status Codes, 12.4.1. The headers with the exception type, message and (if available) root cause exception type and message are added to that request by the FallbackHeaders filter. To enable the Spring Cloud CircuitBreaker filter, you need to place spring-cloud-starter-circuitbreaker-reactor-resilience4j on the classpath. 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. 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. AddResponseHeader is aware of URI variables used to match a path or host. There should be no reason why a filter cannot modify a response header. Sumant Rana 77 Followers Embark on a cloud native journey Follow More from Medium let's see. {githubmaster}/src/main/java/org/springframework/cloud/gateway/security/TokenRelayGatewayFilterFactory.java[filter] Configure for High Availability. This interface and its usage are subject to change in future milestone releases. The following listing shows the definition of the RouteDefinitionLocator interface: By default, a PropertiesRouteDefinitionLocator loads properties by using Spring Boots @ConfigurationProperties mechanism. }, 4. This may not match the actual client IP address if Spring Cloud Gateway sits behind a proxy layer. 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. Once a request has been marked as routed, other routing filters will not route the request again, The following listing configures a SetStatus GatewayFilter: In either case, the HTTP status of the response is set to 401. The following example configures an SetResponseHeader GatewayFilter that uses a variable: The SetStatus GatewayFilter factory takes a single parameter, status.
