spring cloud gateway modify response headers

.build(); GatewaySampleApplication.java. Shortcut configuration is recognized by the filter name, followed by an equals sign (=), followed by argument values separated by commas (,). The following example shows how to do so: The SetPath GatewayFilter factory takes a path template parameter. - thaneesh shanand Apr 16, 2018 at 1:05 The following listing shows how to cache the request body GatewayFilter: CacheRequestBody extracts the request body and converts it to a body class (such as java.lang.String, defined in the preceding example). If the URL has a forward scheme (such as forward:///localendpoint), it uses the Spring DispatcherHandler to handle the request. The input type is a Spring Framework ServerWebExchange. Httpbin.org - a website and diagnosis tool which converts Http GET request data into a JSON response; Step 1: Create a project. The following defaults are configured for Retry filter, if enabled: exceptions: IOException and TimeoutException. This section details how to retrieve route filters, including: To retrieve the global filters applied to all routes, make a GET request to /actuator/gateway/globalfilters. 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. GitHub spring-cloud / spring-cloud-gateway Public Notifications Fork 2.9k Star 3.9k Code Issues 337 Pull requests 39 Actions Projects Security Insights New issue How to modify spring cloud gateway response headers #1092 Closed Gunzenhausen (German pronunciation: [ntsnhazn] (); Bavarian: Gunzenhausn) is a town in the Weienburg-Gunzenhausen district, in Bavaria, Germany.It is situated on the river Altmhl, 19 kilometres (12 mi) northwest of Weienburg in Bayern, and 45 kilometres (28 mi) southwest of Nuremberg.Gunzenhausen is a nationally recognized recreation area. When a request matches a route, the filtering web handler adds all instances of GlobalFilter and all route-specific instances of GatewayFilter to a filter chain. The following listing configures a filter chain: To enable gateway metrics, add spring-boot-starter-actuator as a project dependency. You can configure the SetStatus GatewayFilter to return the original HTTP status code from the proxied request in a header in the response. The preceding route matches if the request contained a red query parameter whose value matched the gree. 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). Each item defines the name and the arguments of a given predicate. The following listing shows how it works: This style also allows for more custom predicate assertions. The unmodified original URL is appended to the list in the ServerWebExchangeUtils.GATEWAY_ORIGINAL_REQUEST_URL_ATTR attribute. series: The series of status codes to be retried, represented by using org.springframework.http.HttpStatus.Series. This route matches if the request has a Host header with a value of www.somehost.org or beta.somehost.org or www.anotherhost.org. The following example configures a PreserveHostHeader GatewayFilter: The RedirectTo GatewayFilter factory takes two parameters, status and url. Well occasionally send you account related emails. The following headers (shown with their default values) are added: Strict-Transport-Security (max-age=631138519), Content-Security-Policy (default-src 'self' https:; font-src 'self' https: data:; img-src 'self' https: data:; object-src 'none'; script-src https:; style-src 'self' https: 'unsafe-inline)'. 1050. Route filters are scoped to a particular route. Am I doing it wrong? The RequestRateLimiter is not configurable with the "shortcut" notation. In .uri("http://someuri") Easy to extend and/or customize using standard Spring patterns After the proxy request is made, the post filter logic is run. Setting this value to zero blocks all requests. 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). The following maxTrustedIndex values yield the following remote addresses: (invalid, IllegalArgumentException during initialization). To enable this for Spring Cloud Gateway add the following dependencies, org.springframework.boot:spring-boot-starter-oauth2-client. Since 4.0.0, Spring Cloud Gateway supports Spring AOT transformations and native images. 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). A burst of 20 is allowed, but, in the next second, only 10 requests are available. The following example configures an AddRequestParameter GatewayFilter that uses a variable: The AddResponseHeader GatewayFilter Factory takes a name and value parameter. Since the request can be read only once, we need to cache the request body. It offers a simple way to manipulate the request path by allowing templated segments of the path. Then the proxy request is made. It provides a convenient method to apply a transformation to JSON body content by deleting attributes from it. In this case, the rate limiter needs to be allowed some time between bursts (according to replenishRate), as two consecutive bursts results in dropped requests (HTTP 429 - Too Many Requests). The DedupeResponseHeader filter also accepts an optional strategy parameter. The following loggers may contain valuable troubleshooting information at the DEBUG and TRACE levels: org.springframework.boot.autoconfigure.web. .route("test1", r -> { Displays information about a particular route. 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. For example, given a Gateway that has 1 replica, the following will . Spring Cloud CircuitBreaker supports multiple libraries that can be used with Spring Cloud Gateway. The following example configures /actuator/gateway/routes: This feature is enabled by default. The APIcast standard policies This is the value of the Location header. The XForwarded Headers Filter creates various X-Forwarded-* headers to send to the downstream service. When a request is made through the gateway to /json/hello, the request is transformed by using the definition provided in hello.proto, sent to com.example.grpcserver.hello.HelloService/hello, and the response back is transformed to JSON. To configure Global http timeouts: You can load-balance websockets by prefixing the URI with lb, such as lb:ws://serviceid. So a request to /hello is sent to /mypath/hello. You can configure the gateway to create routes based on services registered with a DiscoveryClient compatible service registry. By default, it creates a NettyChannel by using the default TrustManagerFactory. A per-route response-timeout with a negative value will disable the global response-timeout value. Those values are then available for use by GatewayFilter factories. 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. also note that the gist doesn't take the decoders into account from upstream like here. The circuit breaker config object takes a list of Want to remove the "warning cannot modify header information" error from your WordPress website? 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). Both offer the same possibilities. The following listing shows how to add local response cache GatewayFilter: The MapRequestHeader GatewayFilter factory takes fromHeader and toHeader parameters. The following example configures an AddResponseHeader GatewayFilter that uses a variable: The Spring Cloud CircuitBreaker GatewayFilter factory uses the Spring Cloud CircuitBreaker APIs to wrap Gateway routes in The following example configures CORS: In the preceding example, CORS requests are allowed from requests that originate from docs.spring.io for all GET requested paths. Multiple matching segments are allowed. it is proxying. This filter can be configured only by using the Java DSL. To remove any kind of sensitive header, you should configure this filter for any routes for which you may want to do so. Add a Header for the original response, configuration example: spring: cloud: gateway: routes: - id: add_response_header_route uri: https://example.org filters: - AddResponseHeader=X-Response-Foo, Bar. It is the name of the query parameter to be removed. 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. HttpHeadersFilters are applied to the requests before sending them downstream, such as in the NettyRoutingFilter. .metadata(CONNECT_TIMEOUT_ATTR, 200); The following listing configures a StripPrefix GatewayFilter: When a request is made through the gateway to /name/blue/red, the request made to nameservice looks like nameservice/red. If youre using load-balanced routes, you need to explicitly define your. By clicking Sign up for GitHub, you agree to our terms of service and The default is 'B' for bytes. It must be a valid Spring HttpStatus. The resulting response is similar to the following: The response contains the details of all the routes defined in the gateway. It does not work in a traditional Servlet Container or when built as a WAR. By default, the RemoteAddr route predicate factory uses the remote address from the incoming request. 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). 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. privacy statement. The earlier configuration examples all use a shortcut notation that uses positional arguments rather than named ones. connect-timeout must be specified in milliseconds. AddResponseHeader is aware of URI variables used to match a path or host. 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. ServerWebExchangeUtils.isAlreadyRouted takes a ServerWebExchange object and checks if it has been routed. public RouteLocator customRouteLocator(RouteLocatorBuilder routeBuilder){ The default filter is a rewrite path filter with the regex /serviceId/?(?. You can combine multiple route predicate factories with logical and statements. If it is not, a status of HTTP 429 - Too Many Requests (by default) is returned. Modifying the Way Remote Addresses Are Resolved, 5.12. The following listing shows the KeyResolver interface: The KeyResolver interface lets pluggable strategies derive the key for limiting requests. The datetime2 parameter must be after datetime1. 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). See the Spring Cloud Project page for details on setting up your build system with the current Spring Cloud Release Train. *) and the replacement /${remaining}. Removes an existing route from the gateway. If you include the starter, but you do not want the gateway to be enabled, set spring.cloud.gateway.enabled=false. In addition, you can configure this filter once by using spring.cloud.gateway.default-filters and have it applied to all routes. To enable RouteDefinition metrics, add spring-boot-starter-actuator as a project dependency. The ServerHttpResponse instance is used to . The KeyResolver is a simple one that gets the user request parameter 2016-10-05: 4.3: CVE-2016-6426 CISCO Have a question about this project? /resource). The Spring Cloud CircuitBreaker filter can also accept an optional fallbackUri parameter. Spring Cloud has it's own way of defining Feign clients, it's done with Spring MVC annotations. The Host route predicate factory takes one parameter: a list of host name patterns. If the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a ws or wss scheme, the websocket routing filter runs. 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. This strips the service ID from the path before the request is sent downstream. 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. Download ZIP. 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. When using the retry filter with any HTTP method with a body, the body will be cached and the gateway will become memory constrained. For a full working sample see this project. In configuration, you can reference the bean by name using SpEL. 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). The SaveSession GatewayFilter factory forces a WebSession::save operation before forwarding the call downstream. . The primary scenario is to use the fallbackUri to define an internal controller or handler within the gateway application. .metadata(RESPONSE_TIMEOUT_ATTR, 200) All pre filter logic is executed. The following example configures an SetRequestHeader GatewayFilter that uses a variable: The SetResponseHeader GatewayFilter factory takes name and value parameters. Spring Cloud Gateway Encryption/Decryption of Request/Response | by Sumant Rana | Level Up Coding Write Sign up Sign In 500 Apologies, but something went wrong on our end. Writing Custom GatewayFilter Factories, 17.2.1. Standard policies to change default 3scale APIcast behavior 3scale provides built-in, standard policies that are units of functionality that modify how APIcast processes requests and responses. ALWAYS_STRIP: The version is always stripped, even if the original request path contains version. This filter also automatically calculates the. There is an abstract class called AbstractRoutePredicateFactory which you can extend. For each global filter, there is a string representation of the filter object (for example, org.spring[emailprotected]77856cc5) and the corresponding order in the filter chain. 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. 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). Some situations necessitate reading the request body. As a result, you can inject request headers and query parameters, for instance, and you can constrain the incoming requests with declarations in the mapping annotation. 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. The status parameter should be a 300 series redirect HTTP code, such as 301. httpStatusCode: The HTTP Status of the request returned to the client. 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. We've already covered its basic usage in earlier tutorials, so we won't get into those aspects here. The Reactor Netty HttpClient and HttpServer can have wiretap enabled. The Before route predicate factory takes one parameter, a datetime (which is a java ZonedDateTime). 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 a RemoteAddr route predicate: This route matches if the remote address of the request was, for example, 192.168.1.10. A Token Relay is where an OAuth2 consumer acts as a Client and return r.host("*.somehost.org").and().path("/somepath") With MVC, it also supports forwarding to a local handler through the forward() method. Spring Cloud Gateway comes with one non-default remote address resolver that is based off of the X-Forwarded-For header, XForwardedRemoteAddressResolver. The RequestHeaderSize GatewayFilter factory takes maxSize and errorHeaderName parameters. The RemoteAddr Route Predicate Factory, 5.10.1. API gateway provides a unified access for services in microservices architecture. Create a ClientResponse object that will hold both the body and the headers: Then extract the body and encrypt it using the EncryptDecryptHelper class. Displays the list of GatewayFilter factories applied to a particular route. This is the number of tokens taken from the bucket for each request and defaults to 1. 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). The gateway can listen for requests on HTTPS by following the usual Spring server configuration. The response is put in the ServerWebExchangeUtils.CLIENT_RESPONSE_ATTR exchange attribute for use in a . For example, to reference a filter named Something in configuration files, the filter When doing so, you need to make sure to include the default predicate and filter shown earlier, if you want to retain that functionality. In the next tutorial of Spring Cloud Gateway Example we will implement these theories and build an application with microservice architecture using Spring Cloud Gateway and demonstrate working examples on web filters to modify request and response body. There are many caching cases on the network, but there are various Bug problems in the testing process. To include Spring Cloud Gateway in your project, use the starter with a group ID of org.springframework.cloud and an artifact ID of spring-cloud-starter-gateway. 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. You can read more about them in the. This combined filter chain is sorted by the org.springframework.core.Ordered interface, which you can set by implementing the getOrder() method. A utility method (called get) is available to make access to these variables easier. Spring Cloud Gateway. The following listing defines a set of default filters: The GlobalFilter interface has the same signature as GatewayFilter. Spring Cloud Gateway offers two RouteDefinitionRepository implementations. The Netty routing filter runs if the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a http or https scheme. 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. Options. status: The HTTP status of the request returned to the client. When setting the The lowercase full name of the secure header needs to be used to disable it.. Retrieving the Routes Defined in the Gateway, 15.5. The following example shows such an errorMessage: There are certain situation when the host header may need to be overridden. The following listing configures a RedirectTo GatewayFilter: This will send a status 302 with a Location:https://acme.org header to perform a redirect. name can contain a space-separated list of header names. The parts parameter indicates the number of parts in the path to strip from the request before sending it downstream. 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. Modify request body. It is added to the ServerWebExchange as the ServerWebExchangeUtils.CIRCUITBREAKER_EXECUTION_EXCEPTION_ATTR attribute that can be used when handling the fallback within the gateway application. 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 maxSize is a DataSize type, so values can be defined as a number followed by an optional DataUnit suffix such as 'KB' or 'MB'. The following listing configures a RewritePath GatewayFilter: For a request path of /red/blue, this sets the path to /blue before making the downstream request. To enable this, set spring.cloud.gateway.discovery.locator.enabled=true and make sure a DiscoveryClient implementation (such as Netflix Eureka, Consul, or Zookeeper) is on the classpath and enabled. Let's simplify this scenario. 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. This is the full configuration of the shortcut configuration of the Cookie predicate shown above. If Spring Cloud Gateway is, for example only accessible through HAProxy, then a value of 1 should be used. Raw. It may be the integer value 404 or the string representation of the enumeration: NOT_FOUND. If the new named header already exists, its values are augmented with the new values. Additionally, to set a multi-valued header, use the header name multiple times like AddRequestHeadersIfNotPresent=X-Request-Color-1:blue,X-Request-Color-1:green. The default list of headers that is removed comes from the IETF. This is the number of tokens the token bucket can hold. The following example configures an AddRequestParameter GatewayFilter: This will add red=blue to the downstream requests query string for all matching requests. Displays the list of routes defined in the gateway. returned from the route it wraps. The algorithm used is the Token Bucket Algorithm. The following example configures a query route predicate: The preceding route matches if the request contained a green query parameter. Usually it's a common requirement that applications can . 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].
