AsyncClientHttpRequestInterceptor (Spring Framework 4.3.30.RELEASE API)

```
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)
                                        throws IOException
```
    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:
    Examine the request and body
    Optionally wrap the request to filter HTTP attributes.
    Optionally modify the body of the request.
    One of the following:
    execute the request through ClientHttpRequestExecution
    don't execute the request to block the execution altogether
    Optionally adapt the response to filter HTTP attributes with the help of ListenableFutureAdapter.
    参数:
    request - the request, containing method, URI, and headers
    body - the body of the request
    execution - the request execution
    返回:
    the response future
    抛出:
    IOException - in case of I/O errors
