HTTP:POST请求收到302,重定向请求是否为GET?

Alb*_*ert 16 post redirect get http http-status-code-302

我正在读这个,但我并没有从那里得到重定向请求应该具有的请求类型,在什么情况下,即函数(初始请求类型,响应类型) - > redirect-request-type.

在我的特定情况下,我有:

  • 初始请求类型:POST
  • 响应类型:302

谷歌浏览器使用GET进行重定向请求.

在Python库请求中,有以下代码(此处):

# http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.3.4
if r.status_code is codes.see_other:
    method = 'GET'
else:
    method = self.method

即,在303(codes.see_other)的情况下,redirect-request-type是GET ,在所有其他情况下,它是初始请求类型.即,就我上面的特定情况而言,与Chrome相比,它将是POST.

这可能是错误的,因为我有一个网站,这实际上似乎没有正确的工作(即网站这种方式表现不佳).

什么是正确的方式/功能?

我只是搜索在Chrome相关的代码,并且在这里它是:

std::string ComputeMethodForRedirect(const std::string& method,
                                     int http_status_code) {
  // For 303 redirects, all request methods except HEAD are converted to GET,
  // as per the latest httpbis draft.  The draft also allows POST requests to
  // be converted to GETs when following 301/302 redirects, for historical
  // reasons. Most major browsers do this and so shall we.  Both RFC 2616 and
  // the httpbis draft say to prompt the user to confirm the generation of new
  // requests, other than GET and HEAD requests, but IE omits these prompts and
  // so shall we.
  // See:
  // https://tools.ietf.org/html/draft-ietf-httpbis-p2-semantics-17#section-7.3
  if ((http_status_code == 303 && method != "HEAD") ||
      ((http_status_code == 301 || http_status_code == 302) &&
       method == "POST")) {
    return "GET";
  }
  return method;
}

根据RFC 2616,答案是"原始方法".HTTPbis会对此进行修改,因为它不能反映浏览器的功能(遗憾的是).
