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?

推荐答案

你可以通过几个Request 字段:

You can examine the url through several Request fields:

假设您的应用程序正在侦听以下应用程序根目录:

Imagine your application is listening on the following application root:

http://www.example.com/myapplication

并且用户请求以下 URI:

And a user requests the following URI:

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

在这种情况下，上述属性的值如下:

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

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

您可以通过适当的拆分轻松提取主体部分.

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