如何获取Flask请求的url的不同部分？ [英] How do I get the different parts of a Flask request's url?

问题描述

我想检测请求是来自 localhost：5000 还是 foo.herokuapp.com 主机，请求什么路径。如何获取有关Flask请求的信息？

可以通过几个 Request 字段：

用户请求以下URL：

  http： //www.example.com/myapplication/page.html?x=y 
  

在这种情况下，

  path /page.html 
 script_root / myapplication 
 base_url http://www.example.com/myapplication/page.html 
网址http://www.example.com/myapplication/page.html?x=y 
 url_root http：// www.example.com/myapplication/ 
  

您可以轻松地提取主持人部分与适当的分裂。

I want to detect if the request came from the localhost:5000 or foo.herokuapp.com host and what path was requested. How do I get this information about a Flask request?

解决方案

You can examine the url through several Request fields:

A user requests the following URL:

    http://www.example.com/myapplication/page.html?x=y

In this case the values of the above mentioned attributes would be the following:

    path             /page.html
    script_root      /myapplication
    base_url         http://www.example.com/myapplication/page.html
    url              http://www.example.com/myapplication/page.html?x=y
    url_root         http://www.example.com/myapplication/

You can easily extract the host part with the appropriate splits.
