推荐答案

在请求中使用范围，要求特定范围（或范围）的字节。在响应中使用 Content-Range 来表示服务器给你的字节数（可能与你请求的范围不同），以及整个内容的长度（如果已知）。

Range is used in the request, to ask for a particular range (or ranges) of bytes. Content-Range is used in the response, to indicate which bytes the server is giving you (which may be different than the range you requested), as well as how long the entire content is (if known).
