python - 如何获取 Flask 请求的 url 的不同部分？

Question

我想检测请求是否来自 localhost:5000 或 foo.herokuapp.com 主机以及请求的路径。如何获取有关 Flask 请求的信息？

Answer 1

您可以通过几个Request 来查看网址。字段:

Imagine your application is listening on the following application root:

http://www.example.com/myapplication

And a user requests the following URI:

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

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机部分。

一个使用这个的例子:

from flask import request

@app.route('/')
def index():
    return request.base_url
