requests如何查看cookies和发送cookies

如果某个响应中包含一些 cookie，你可以快速访问它们：

>>> url = 'http://example.com/some/cookie/setting/url'
>>> r = requests.get(url)

>>> r.cookies['example_cookie_name']
'example_cookie_value'

要想发送你的cookies到服务器，可以使用 cookies 参数：

>>> url = 'http://httpbin.org/cookies'
>>> cookies = dict(cookies_are='working')

>>> r = requests.get(url, cookies=cookies)
>>> r.text
'{"cookies": {"cookies_are": "working"}}'

Cookie 的返回对象为 RequestsCookieJar，它的行为和字典类似，但界面更为完整，适合跨域名跨路径使用。你还可以把 Cookie Jar 传到 Requests 中：

>>> jar = requests.cookies.RequestsCookieJar()
>>> jar.set('tasty_cookie', 'yum', domain='httpbin.org', path='/cookies')
>>> jar.set('gross_cookie', 'blech', domain='httpbin.org', path='/elsewhere')
>>> url = 'http://httpbin.org/cookies'
>>> r = requests.get(url, cookies=jar)
>>> r.text
'{"cookies": {"tasty_cookie": "yum"}}'
