燒瓶如何獲得請求的HTTP_ORIGIN

Question

我想通過自己設置的「Access-Control-Allow-Origin」頭來做出響應，但它似乎搞不清楚「HTTP_ORIGIN 「參數與請求是一起的。

Answer 1

我使用瓶 - 0.10.1和HTTP_ORIGIN似乎是這個object

flask.request.environ 

這裏ATTRS之一是處理一個請求時，我從print flask.request.environ有：

} 

Answer 2

這將讓你的答案

from flask import request 
... 
if request.environ['HTTP_ORIGIN'] is not None: 
    print request.environ['HTTP_ORIGIN']
