http-headers - 使用 HEAD 请求 POST 数据

Question

是否可以使用 HEAD 请求发送 POST 数据？

Answer 1

不，HEAD 请求不同于 POST 请求。 HEAD 请求不接受发布数据。来自 HTTP specification section 9.4 :

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。
