除此之外，还有一个与区间请求相关的响应报头Accept-Ranges，它表示服务端能够接受的区间类型。...例如，前面针对条件请求的响应都具有一个Accept-Ranges: bytes报头，表示服务支持针对资源的区间划分。如果该报头的值被设置为none，则意味着服务端不支持区间请求。...Kestrel Content-Length: 26 Content-Range: bytes 3-28/39 Last-Modified: Wed, 18 Sep 2019 23:15:14 GMT Accept-Ranges...Kestrel Content-Length: 10 Content-Range: bytes 29-38/39 Last-Modified: Wed, 18 Sep 2019 23:15:14 GMT Accept-Ranges...Content-Type: text/plain Server: Kestrel Content-Length: 39 Last-Modified: Wed, 18 Sep 2019 23:15:14 GMT Accept-Ranges

假如在响应中存在 Accept-Ranges 首部（并且它的值不为 none），那么表示该服务器支持范围请求。...Accept-Ranges: bytes Content-Length: 146515 如果站点未发送 Accept-Ranges 首部，那么它们有可能不支持范围请求。

response.getheaders()) print('-'*5+'Message'+'-'*5) print(response.msg) 执行代码后结果如下： status:200 -----Headers----- [('Accept-Ranges...Content-Leng th', '93'), ('Date', 'Thu, 06 Aug 2020 13:23:28 GMT'), ('Server', 'server')] -----Message----- Accept-Ranges
这可以通过设置HTTP的 Accept-Ranges 响应头信息来实现。...PHP代码如下： header('Accept-Ranges: bytes'); Accept-Ranges: bytes 告诉浏览器，该资源支持以字节为单位的部分传输。...不过要注意的是，这里涉及到需要发送多个HTTP响应头信息，具体如下： header('HTTP/1.1 206 Partial Content'); header('Accept-Ranges: bytes
