To disable it, set the following property: This will default to true in a future release. It adds the Host header, scheme and port of the current request to any existing Forwarded header. Code Revisions 1 Stars 14 Forks 3. consumer can be a pure Client (like an SSO application) or a Resource The After route predicate factory takes one parameter, a datetime (which is a java ZonedDateTime). 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 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. There should be no reason why a filter cannot modify a response header. The following example configures an SetResponseHeader GatewayFilter that uses a variable: The SetStatus GatewayFilter factory takes a single parameter, status. In configuration, reference the bean by name using SpEL. The following example configures a Spring Cloud CircuitBreaker GatewayFilter: To configure the circuit breaker, see the configuration for the underlying circuit breaker implementation you are using. This is the full configuration of the shortcut configuration of the Cookie predicate shown above. Retrieving the Routes Defined in the Gateway, 15.5. 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). URI variables may be used in the value and will be expanded at runtime. In addition, through the spring.cloud.gateway.metrics.tags.path.enabled property (by default, false), you can activate an extra metric with the path tag: These metrics are then available to be scraped from /actuator/metrics/spring.cloud.gateway.requests and can be easily integrated with Prometheus to create a Grafana dashboard. The routine of modifying the response body with Spring Cloud Gateway is the same as the previous request body; Configure routing and filters through code; . import static org.springframework.cloud.gateway.support.RouteMetadataUtils.RESPONSE_TIMEOUT_ATTR; @Bean Fork 3. 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. 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. 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). A Token Relay is where an OAuth2 consumer acts as a Client and First-class support is provided for sensitive headers (by default, cookie and authorization), which are not passed downstream, and for proxy (x-forwarded-*) headers. 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. If the information is not provided within the next 7 days this issue will be closed. If Spring Cloud Gateway is, for example only accessible through HAProxy, then a value of 1 should be used. keyResolver is a bean that implements the KeyResolver interface. This appendix provides a list of common Spring Cloud Gateway properties and references to the underlying classes that consume them. It uses the Netty HttpClient to make the downstream proxy request. A utility method (called get) is available to make access to these variables easier. Easy to extend and/or customize using standard Spring patterns If it is not matched, the filter does nothing. The accepted values are RETAIN_FIRST (default), RETAIN_LAST, and RETAIN_UNIQUE. The route configuration allows applying CORS directly to a route as metadata with key cors. 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. In the example below the call consumingServiceEndpoint/users/1 will be redirected to inCaseOfFailureUseThis/users/1. The following example configures a XForwardedRemoteAddr route predicate: This route matches if the X-Forwarded-For header contains, for example, 192.168.1.10. A per-route response-timeout with a negative value will disable the global response-timeout value. For each factory there is a string representation of the corresponding object (for example, [[emailprotected] configClass = Object]). 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. URIs defined in routes without a port get default port values of 80 and 443 for the HTTP and HTTPS URIs, respectively. 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 predicate matches requests that happen after the specified datetime. Let's simplify this scenario. 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. I got the root cause. GatewaySampleApplication.java. Zuul profile. The resulting response is similar to the following: The response contains the details of the GatewayFilter factories applied to any particular route. AddRequestHeader is aware of the URI variables used to match a path or host. You can use the ModifyRequestBody filter to modify the request body before it is sent downstream by the gateway. Star 14. 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'. In this situation, the SetRequestHostHeader GatewayFilter factory can replace the existing host header with a specified value. The mapper is a Function that takes the incoming ResponseEntity and converts it to an outgoing one. In subsequent calls, this value is recalculated with the number of seconds left until the response expires. 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. If maxBackoff is configured, the maximum backoff applied is limited to maxBackoff. The RequestRateLimiter is not configurable with the "shortcut" notation. Displays the list of routes defined in the gateway. To retrieve the GatewayFilter factories applied to routes, make a GET request to /actuator/gateway/routefilters. Spring cloud gateway response body modification. as the separator. Policy to specify how to modify the response code, body and headers. The following example configures a host route predicate: URI template variables (such as {sub}.myhost.org) are supported as well. The default predicate is a path predicate defined with the pattern /serviceId/**, where serviceId is response-timeout must be specified in milliseconds. The following example configures an AddResponseHeader GatewayFilter: This adds X-Response-Red:Blue header to the downstream responses headers for all matching requests. There is an abstract class called AbstractRoutePredicateFactory which you can extend. To retrieve the routes defined in the gateway, make a GET request to /actuator/gateway/routes. The RemoveHopByHop Headers Filter removes headers from forwarded requests. The following listing configures a SetStatus GatewayFilter: In either case, the HTTP status of the response is set to 401. For relative redirects, you should use uri: no://op as the uri of your route definition. For more information on circuit breakers and the gateway see the Spring Cloud CircuitBreaker Factory section. The following examples show how to do so: Custom filters class names should end in GatewayFilterFactory. It requires the use of the spring-boot-starter-data-redis-reactive Spring Boot starter. methods: The HTTP methods that should be retried, represented by using org.springframework.http.HttpMethod. Here is a link to someone asking about ordered filters that may provide more insight: #1341. None of the prior documentation applies to what follows. The SetRequestHeader GatewayFilter factory takes name and value parameters. This filter adds a timer metric named spring.cloud.gateway.requests with the following tags: routeUri: The URI to which the API is routed. The Host route predicate factory takes one parameter: a list of host name patterns. The following listing shows how to modify a request body GatewayFilter: You can use the ModifyResponseBody filter to modify the response body before it is sent back to the client. For more detailed examples of how to use any of the following filters, take a look at the. 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). The following example configures a PreserveHostHeader GatewayFilter: The RedirectTo GatewayFilter factory takes two parameters, status and url. The Retry GatewayFilter factory supports the following parameters: retries: The number of retries that should be attempted. It uses the Host header, scheme, port and path of the current request to create the various headers. 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. By default, the gateway defines a single predicate and filter for routes created with a DiscoveryClient. status: The HTTP status of the request returned to the client. GitHub Gist: instantly share code, notes, and snippets. For example, given a Gateway that has 1 replica, the following will . The XForwarded Remote Addr route predicate factory takes a list (min size 1) of sources, which are CIDR-notation (IPv4 or IPv6) strings, such as 192.168.0.1/16 (where 192.168.0.1 is an IP address and 16 is a subnet mask). The following example configures a PrefixPath GatewayFilter: This prefixes /mypath to the path of all matching requests. 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. 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. The errorHeaderName parameter sets the name of the response header containing an error message, by default it is "errorMessage". The following example configures a method route predicate: This route matches if the request method was a GET or a POST. It does not work in a traditional Servlet Container or when built as a WAR. It adds more detail to each route, letting you view the predicates and filters associated with each route along with any configuration that is available. It uses Java regular expressions for a flexible way to rewrite the response header value. CircuitBreaker also supports URI variables in the fallbackUri. Creating and Deleting a Particular Route, 15.8. The collection of filters applied to the route. 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. Route: The basic building block of the gateway. Spring cloud gateway response body modification. {githubmaster}/src/main/java/org/springframework/cloud/gateway/security/TokenRelayGatewayFilterFactory.java[filter] .application.yml. URI variables may be used in the value and are expanded at runtime. Modify request body. This may not match the actual client IP address if Spring Cloud Gateway sits behind a proxy layer. The circuit breaker config object takes a list of It is the permissible size limit of the request defined in bytes. 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. There are many caching cases on the network, but there are various Bug problems in the testing process. To see the list of all Spring Cloud Gateway related configuration properties, see the appendix. Spring Cloud Zuul is one of the core components of Spring Cloud Netflix subproject. The following example configures an after route predicate: This route matches any request made after Jan 20, 2017 17:42 Mountain Time (Denver). 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. return routeBuilder.routes() Acompanhe-nos: can gabapentin help with bell's palsy Facebook For a production deployment, you can configure the gateway with a set of known certificates that it can trust with the following configuration: If the Spring Cloud Gateway is not provisioned with trusted certificates, the default trust store is used (which you can override by setting the javax.net.ssl.trustStore system property). The following example configures a RewriteResponseHeader GatewayFilter: For a header value of /42?user=ford&password=omg!what&flag=true, it is set to /42?user=ford&password=***&flag=true after making the downstream request. response-timeout must be specified as a java.time.Duration. While a Gateway is running you can use kubectl scale to modify the number of replicas. 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. It is the name of the header to be removed. connect-timeout must be specified in milliseconds. You signed in with another tab or window. Add a response header named X-Request-Foo with a value of Bar to the original response. If matchTrailingSlash is set to false, then request path /red/1/ will not be matched. SetResponseHeader is aware of URI variables used to match a path or host. This uses Java regular expressions for a flexible way to rewrite the request path. returned from the route it wraps. Spring Cloud Gateway || Modify Response Body Using Post Global Filter modify response body of route in spring cloud gateway Hi everyone, have you ever worked with Filters ? The filter takes the following arguments: This file can be generated using protoc and specifying the --descriptor_set_out flag: service: Fully qualified name of the service that handles the request. If the URL has a forward scheme (such as forward:///localendpoint), it uses the Spring DispatcherHandler to handle the request. response Header Transformations: . 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. ServerWebExchangeUtils.isAlreadyRouted takes a ServerWebExchange object and checks if it has been routed. Retries are performed after a backoff interval of firstBackoff * (factor ^ n), where n is the iteration. The DedupeResponseHeader GatewayFilter factory takes a name parameter and 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. backoff: The configured exponential backoff for the retries. 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. 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. Have a question about this project? The RemoveRequestHeader GatewayFilter factory takes a name parameter. The Method Route Predicate Factory takes a methods argument which is one or more parameters: the HTTP methods to match. Temporary bursts can be allowed by setting burstCapacity higher than replenishRate. Future milestone versions will have RouteDefinitionLocator implementations based off of Spring Data Repositories, such as Redis, MongoDB, and Cassandra. also note that the gist doesn't take the decoders into account from upstream like here. The following example creates a Logback configuration: You can configure the gateway to control CORS behavior globally or per route. Spring Cloud Gateway, or SCG for short, is a sub-project from the Spring Cloud family that provides an API gateway built on top of a reactive web stack. The RewritePath GatewayFilter factory takes a path regexp parameter and a replacement parameter. The j_spring_security_switch_user function in Cisco Unified Intelligence Center (CUIC) 8.5.4 through 9.1(1), as used in Unified Contact Center Express 10.0(1) through 11.0(1), allows remote attackers to create user accounts by visiting an unspecified web page, aka Bug IDs CSCuy75027 and CSCuy81653. The Header route predicate factory takes two parameters, the header and a regexp (which is a Java regular expression). The SecureHeaders GatewayFilter factory adds a number of headers to the response, per the recommendation made in this blog post. For a full working sample see this project. The most noteworthy thing here is: ServerHttpRequest or HttpMessage interface provides a method to get the request headers HttpHeaders getHeaders(); returns a read-only instance, specifically of type ReadOnlyHttpHeaders, mentioned here more than once I wrote this blog post using Spring Cloud Gateway version Greenwich.SR1. Passing headers with Spring Cloud Feign. AddRequestHeadersIfNotPresent also supports URI variables used to match a path or host. When setting the Spring Cloud Gateway includes many built-in GatewayFilter Factories. How does it work? Route filters are scoped to a particular route. import static org.springframework.cloud.gateway.support.RouteMetadataUtils.CONNECT_TIMEOUT_ATTR; 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. After the proxy request is made, the post filter logic is run. Want to remove the "warning cannot modify header information" error from your WordPress website? Various properties can be specified inside your application.properties file, inside your application.yml file, or as command line switches. You can load-balance websockets by prefixing the URI with lb, such as lb:ws://serviceid. If the input header does not exist, the filter has no impact. 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. This filter takes an optional keyResolver parameter and parameters specific to the rate limiter (described later in this section). InMemoryRouteDefinitionRepository which only lives within the memory of one Gateway instance. Multiple matching segments are allowed. The algorithm used is the Token Bucket Algorithm. forwards the incoming token to outgoing resource requests. 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 . The DedupeResponseHeader filter also accepts an optional strategy parameter. To write a custom global filter, you must implement GlobalFilter interface as a bean. 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. Some situations necessitate reading the request body. 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.) API gateway provides a unified access for services in microservices architecture. This predicate matches with a header that has the given name whose value matches the regular expression. This project provides an API Gateway built on top of the Spring Ecosystem, including: Spring 6, Spring Boot 3 and Project Reactor. The protocolsRegex parameter must be a valid regex String, against which the protocol name is matched. The following listing shows the KeyResolver interface: The KeyResolver interface lets pluggable strategies derive the key for limiting requests. The new URI is placed in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute. The predicates defined by RouteDefinitionLocator beans are combined using logical and. 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. The default filter is a rewrite path filter with the regex /serviceId/?(?. The following example configures a before route predicate: This route matches any request made before Jan 20, 2017 17:42 Mountain Time (Denver). The filter takes a host parameter. This applies the filter to all requests. 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). You can configure additional parameters for each route by using metadata, as follows: You could acquire all metadata properties from an exchange, as follows: Http timeouts (response and connect) can be configured for all routes and overridden for each specific route. The input type is a Spring Framework ServerWebExchange. Configuring Route Predicate Factories and Gateway Filter Factories, 5.10. The LocalResponseCache runs if its associated property is enabled (spring.cloud.gateway.filter.local-response-cache.enabled) and activates a local cache using Caffeine for all responses that meet the following criteria: The response has one of the following status codes: HTTP 200 (OK), HTTP 206 (Partial Content), or HTTP 301 (Moved Permanently). This allows more complex routing options, like forwarding sections of the original host or url path using PathPattern expression. NOTE: This is not recommended for production. In case of the request being forwarded to fallback, the Spring Cloud CircuitBreaker Gateway filter also provides the Throwable that has caused it. Otherwise, the original value in the client request is sent. The unmodified original URL is appended to the list in the ServerWebExchangeUtils.GATEWAY_ORIGINAL_REQUEST_URL_ATTR attribute.
