如何从Selenium浏览器加载会话和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)

给了我以下例外：

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，你必须从你的驱动程序实例中获取cookie：

cookies = driver.get_cookies()

这会为您的会话返回set of 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'])

Answer 2

您可以使用第三方请求程序包，例如selenium-requests或requestium。它们提供了在请求和硒之间共享cookie的功能。

Answer 3

我做了这个解决方案，它解决了意外的关键字参数过期

def getSurrounding(center_position, range, position_dictionnary):
    for x,y in position_dictionnary:
         if abs(center_position.x - x) + abs(center_position.y - y) < range:
             yield position_dictionnary[(x,y)]
