推荐答案

Range 用于请求中，用于请求特定范围(或范围)的字节.Content-Range 用于响应中，以指示服务器提供给您的字节数(可能与您请求的范围不同)，以及整个内容的长度(如果知道).

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).
