Interface AsyncClientHttpRequestInterceptor

Deprecated.

as of Spring 5.0, in favor of ExchangeFilterFunction

@Deprecated
public interface AsyncClientHttpRequestInterceptor

Intercepts client-side HTTP requests. Implementations of this interface can be registered with the AsyncRestTemplate as to modify the outgoing HttpRequest and/or register to modify the incoming ClientHttpResponse with help of a ListenableFutureAdapter.

The main entry point for interceptors is intercept(org.springframework.http.HttpRequest, byte[], org.springframework.http.client.AsyncClientHttpRequestExecution).

ListenableFuture<ClientHttpResponse> intercept(HttpRequest request,
                                               byte[] body,
                                               AsyncClientHttpRequestExecution execution)

Deprecated.

Intercept the given request, and return a response future. The given AsyncClientHttpRequestExecution allows the interceptor to pass on the request to the next entity in the chain.

An implementation might follow this pattern:

1. Examine the request and body
2. Optionally wrap the request to filter HTTP attributes.
3. Optionally modify the body of the request.
4. One of the following:
   • execute the request through ClientHttpRequestExecution
   • don't execute the request to block the execution altogether
5. Optionally adapt the response to filter HTTP attributes with the help of ListenableFutureAdapter.

Parameters:

request - the request, containing method, URI, and headers

body - the body of the request

execution - the request execution

Returns:

the response future

Throws:

java.io.IOException - in case of I/O errors
