Question

我想用＆＃34; Access-Control-Allow-Origin＆＃34;做出回应。标题一直由我自己设置，而它似乎搞砸了＆＃34; HTTP_ORIGIN＆＃34;参数随请求而来。

Answer 1

我正在使用 flask - 0.10.1 ，HTTP_ORIGIN似乎是此object的其中一个

flask.request.environ

以下是我在处理请求时从print flask.request.environ获得的内容：

{
  "wsgi.multiprocess": false,
  "HTTP_REFERER": "http://www.freemerce.com/product/77104116",
  "SERVER_SOFTWARE": "Werkzeug/0.9.6",

  "CONTENT_TYPE": "",
  "HTTP_ACCEPT_ENCODING": "gzip, deflate, sdch"
}

...
if request.environ['HTTP_ORIGIN'] is not None:
