是否可以使用HEAD请求发送POST数据？ 不,HEAD请求与POST请求不同. HEAD请求不接受发布数据.从 HTTP specification section 9.4： The HEAD method is identical to GET except that the server MUST NOT return a message-bo
The HEAD method is identical to GET except that the server MUST NOT return a message-body in the response. The metainformation contained in the HTTP headers in response to a HEAD request SHOULD be identical to the information sent in response to a GET request. This method can be used for obtaining metainformation about the entity implied by the request without transferring the entity-body itself. This method is often used for testing hypertext links for validity, accessibility, and recent modification.
由于GET请求不包含发布数据,因此HEAD请求也不包含发布数据.
