Cookie 政策被忽略？

Question

我正在尝试使用 requests.Session to make some requests and I'd like cookies to not be set. Looking at this question，看来我可以创建一个 cookie 策略，并根据该策略创建一个 cookie jar 以忽略 cookie。但是，对于我的请求，似乎仍设置了 cookie：

from http import cookiejar

class BlockAll(cookiejar.CookiePolicy):
        """ Blocks all cookies for a given request.
        """
        return_ok = set_ok = domain_return_ok = path_return_ok = lambda self, *args, **kwargs: False
        netscape = True
        rfc2965 = hide_cookie2 = False


def get_cookie_jar():
    cookies = cookiejar.CookieJar(policy=BlockAll())
    return cookies

session = requests.Session()
response = session.request(
   method='post',
   url='some_url.com',
   cookies=get_cookie_jar(),
   ....
)

print(response.cookies)
<RequestsCookieJar[Cookie(version=0, name='JSESSIONID', value='1234', port=None, port_specified=False, domain='some_url.com', domain_specified=False, domain_initial_dot=False, path='/', path_specified=True, secure=False, expires=None, discard=True, comment=None, comment_url=None, rest={}, rfc2109=False)]>

这是为此类请求设置策略的正确方法吗？非常感谢任何帮助/相关文档的链接。

request(...) 的 cookies 参数允许您在请求上指定传出 cookies 。不会在响应.

上查询传入的 cookie
您需要在会话上设置策略：

session = requests.Session() session.cookies.set_policy(BlockAll())

演示：

>>> session = requests.Session() >>> response = session.request('GET', 'http://httpbin.org/cookies/set?foo=bar') >>> session.cookies # no policy, so cookie got set <RequestsCookieJar[Cookie(version=0, name='foo', value='bar', port=None, port_specified=False, domain='httpbin.org', domain_specified=False, domain_initial_dot=False, path='/', path_specified=True, secure=False, expires=None, discard=True, comment=None, comment_url=None, rest={}, rfc2109=False)]> >>> session.cookies.clear() # clean slate, no cookies >>> session.cookies <RequestsCookieJar[]> >>> session.cookies.set_policy(BlockAll()) >>> response = session.request('GET', 'http://httpbin.org/cookies/set?foo=bar') >>> session.cookies # with policy, cookies still empty <RequestsCookieJar[]>
