Question

我正在使用Python Requests libray登录网站。为此，我需要捕获登录页面的一些数据，然后使用它向同一页面发出POST请求。

我的第一种方法是：

import requests
from bs4 import BeautifulSoup
from contextlib import contextmanager

def get_data(soup, ids, **kwargs):
    pass

@contextmanager
def login_session(username='user', password='pass'):
    auth = {'username': username, 'password': password}
    url = 'http://example.com/Login.aspx'
    ids = ('#this', '#other')

    with requests.Session() as s:
        soup = BeautifulSoup(s.get(url).content)
        s.post(url, data=get_data(soup, ids, **auth))
        yield s

with login_session() as s:
    page = s.get('http://example/protected.aspx').content

但是，我发现请求提供BaseAuth课程来制作custom authentication。

所以，我尝试实现自己的CustomAuth

import requests

class CustomAuth(AuthBase):

    ids = ('#this', '#other')
    url = "http://example.com/Login.aspx"

    def __init__(self, username, password):
        self.username = username
        self.password = password

    def _get_data(self, soup):
        pass

    def __call__(self, r):
        '''Prepare data for POST request'''

        with requests.Session() as s:
            soup = BeautifulSoup(s.get(self.url).content)
            r.data = self._get_data(soup)
        return r

with requests.Session() as s:
    s.post(CustomAuth.url, auth=CustomAuth('user','pass'))

但它没有按预期工作。 那么，是否可以在这种情况下使用BaseAuth？

Python请求BaseAuth类和自定义POST数据？
