如何将会话和cookies从Selenium browser加载到Python中的请求库？

Question

如何从Selenium browser加载会话和cookie？以下代码：

import requests

cookies = [{u'domain': u'academics.vit.ac.in',
            u'name': u'ASPSESSIONIDAEQDTQRB',
            u'value': u'ADGIJGJDDGLFIIOCEZJHJCGC',
            u'expiry': None, u'path': u'/',
            u'secure': True}]
response = requests.get(url2, cookies=cookies)

给我以下例外：

Traceback (most recent call last):
  File "F:\PYTHON\python_scripts\cookies\cookies3.py", line 23, in <module>
    response = requests.get(url2, cookies=cookies)
  File "C:\Python27\lib\site-packages\requests\api.py", line 68, in get
    return request('get', url, **kwargs)<br/>
  File "C:\Python27\lib\site-packages\requests\sessions.py", line 450, in request
    prep = self.prepare_request(req)
    cookies = cookiejar_from_dict(cookies)
  File "C:\Python27\lib\site-packages\requests\cookies.py", line 439, in cookiejar_from_dict
    cookiejar.set_cookie(create_cookie(name, cookie_dict[name]))
TypeError: list indices must be integers, not dict

Answer 1

首先，您必须从驱动程序实例获取cookies：

cookies = driver.get_cookies()

这将返回会话的cookie dictionaries。

接下来，在requests中设置这些cookie：

s = requests.Session()
for cookie in cookies:
    s.cookies.set(cookie['name'], cookie['value'])
