intercept

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

A typical implementation of this method would follow the following pattern:

1. Examine the HttpRequest and body
2. Optionally org.springframework.http.client.support.HttpRequestWrapper the request to filter HTTP attributes.
3. Optionally modify the body of the request.
4. Either
   • execute the request using ClientHttpRequestExecution#execute(org.springframework.http.HttpRequest, byte[]),
   or
   • do not execute the request to block the execution altogether.
5. Optionally wrap the response to filter HTTP attributes.

Parameters

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

body - the body of the request

execution - the request execution

Exceptions

IOException - in case of I/O errors

Return
the response
