Question

我向请求图片但使用带有多个范围的范围标头的服务器发送http请求，请求文本为：

GET /images/nav_logo102.png HTTP/1.1

但服务器正在回复

HTTP/1.1 200 OK

并发送整个图像如果我尝试相同的东西，但只有一个范围，它的工作原理，我只得到请求的范围。知道如何提出要求吗？

Answer 1

您应该在最后一个标题后添加\ r \ n \ r \ n。

请求：

GET /images/djsBox_2.jpg HTTP/1.1\r\n
Range: bytes=0-2,10-20\r\n
Host: www.djsoft.net\r\n
Accept: */*\r\n
\r\n

我使用WFetch工具进行了检查，回复为HTTP/1.1 206 Partial Content\r\n

服务器实际返回了2部分数据：

Accept-Ranges: bytes\r\n
Content-Length: 196\r\n
Content-Type: multipart/byteranges; boundary=4b9e42cd78baa9\r\n
\r\n
\r\n
--4b9e42cd78baa9\r\n
Content-type: image/jpeg\r\n
Content-range: bytes 0-2/4543\r\n
\r\n
яШя\r\n
--4b9e42cd78baa9\r\n
Content-type: image/jpeg\r\n
Content-range: bytes 10-20/4543\r\n
\r\n
\x000\x001\x001\x001\x000`\x000`\x000\x000я\r\n
--4b9e42cd78baa9--\r\n

具有多个范围的http请求返回HTTP / 1.1 200 OK
