问题描述
如果不支持 Range ，则对带有标题字段 Range:bytes = 278528-的GET请求的正确响应是什么?
What is the correct response to a GET request with the header field Range: bytes=278528- if Range is not supported?
读取HTTP标头定义( http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html )我认为我至少应该设置: Accept-Ranges:none ，但它明确指出
Reading the HTTP header definitions (http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html) i think i should at least set: Accept-Ranges: none, but it clearly states that
因此，如果客户请求范围，我应该:
So, if a client requests a range, should I:
- 从字节0开始答复整个文件吗?
- 回复一些状态错误?(400/406/416/501)，请参见: http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html
推荐答案
您可能会忽略它，如规范所述.准确地说:
You may ignore it, as the spec says. To be precise:
- 如果支持，则返回状态码206 Partial Content，并包含适当的标头，例如Content-Range.
- 如果您不支持它，则会照常返回200 OK.
我还没有测试过，但是规格似乎很清楚.我已经看到了这项工作-如果服务器不支持Range标头，则使用wget或curl恢复中断的下载将可以从头开始正确重启.
I have not tested this, but the spec seems pretty clear. I have seen this work — using wget or curl to resume an interrupted download will properly restart from the beginning if the server does not support the Range header.
