方法详细资料

intercept

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:

1. Examine the request and body.
2. Optionally wrap the request to filter HTTP attributes.
3. Optionally modify the body of the request.
• Either
• execute the request using ClientHttpRequestExecution.execute(cn.taketoday.http.HttpRequest, byte[]),
• or
• do not execute the request to block the execution altogether.
4. 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
