HTTP: body

Requests body

请求报文的报文体大致上可以分为如下两种:

• Single-resource bodies, consisting of one single file, defined by the two headers: Content-Typeand Content-Length.
• Multiple-resource bodies, consisting of a multipart body, each containing a different bit of information. This is typically associated with HTML Forms

Response body

并不是所有的响应都有报文体:
responses with a status code, like 201or 204, usually don't.

响应报文体大致上可以分为一下三种:

• Single-resource bodies, consisting of a single file of known length, defined by the two headers: Content-Type and Content-Length
• Single-resource bodies, consisting of a single file of unknown length, encoded by chunks with Transfer-Encodingset to chunked.
• Multiple-resource bodies, consisting of a multipart body, each containing a different section of information. These are relatively rare.
