HTTP OPTIONS请求可以返回204还是总是返回200？ [英] Can an HTTP OPTIONS request return a 204 or should it always return 200?

问题描述

根据 http://www.w3.org/ Protocols / rfc2616 / rfc2616-sec9.html＃sec9.2 有关HTTP OPTIONS请求的唯一响应是200.但是，似乎有一些情况，例如当内容长度为0时，一个204会更合适。 HTTP OPTIONS请求是否适合返回204？

According to http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html#sec9.2 the only response ever mentioned regarding an HTTP OPTIONS request is a 200. However, there seem to be cases such as when the content-length is 0 that a 204 would be more appropriate. Is it appropriate for an HTTP OPTIONS request to return a 204?

Yes, it can return 204. Or 400. Or 400. There is no general restriction as to what status codes a method can return.

还要注意是时候停止查看RFC 2616.参见 http://trac.tools.ietf.org/wg/httpbis/trac/wiki 。
