```
ClientHttpResponse intercept(HttpRequest request,
                             byte[] body,
                             ClientHttpRequestExecution execution)
                      throws IOException
```
    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:
    Examine the request and body
    Optionally wrap the request to filter HTTP attributes.
    Optionally modify the body of the request.
    Either
    execute the request using ClientHttpRequestExecution.execute(org.springframework.http.HttpRequest, byte[]),
    or
    do not execute the request to block the execution altogether.
    Optionally wrap the response to filter HTTP attributes.
    参数:
    request - the request, containing method, URI, and headers
    body - the body of the request
    execution - the request execution
    返回:
    the response
    抛出:
    IOException - in case of I/O errors
