按原样单独获取cookie - Python 请求

Question

所以我正在尝试编写一个小脚本，其中包含requests库，该脚本向站点发出请求（例如 github.com），并解析响应标头中的cookie。因此，当您向 github.com 发出请求时，有 3 个不同的 Set-Cookie 标头，如下所示：

Set-Cookie: has_recent_activity=1; path=/; expires=Thu, 27 Dec 2018 07:54:16 -0000
Set-Cookie: logged_in=no; domain=.github.com; path=/; expires=Mon, 27 Dec 2038 06:54:16 -0000; secure; HttpOnly
Set-Cookie: _gh_sess=MldFM3p...; path=/; secure; HttpOnly

现在，当您通过 requests API 发出请求并通过 req.headers.get('Set-Cookie') 检查Set-Cookie标头时，所有这些 cookie 值都合并为一个：

has_recent_activity=1; path=/; expires=Thu, 27 Dec 2018 07:54:16 -0000, logged_in=no; domain=.github.com; path=/; expires=Mon, 27 Dec 2038 06:54:16 -0000; secure; HttpOnly, _gh_sess=MldFM3p...; path=/; secure; HttpOnly

所以我的问题是我如何获得 3 个明显独立的完整 cookie，因为它是由服务器发送的，以及所有 cookie 元数据信息（可能以列表的形式）？

我是 Python 的新手，所以任何帮助将不胜感激。干杯！

老实说，我不明白你想知道的问题评论是什么，但如果你想要一种方法来解决下面的问题，那会很容易。

所以我的问题是我如何获得 3 个明显独立的 cookie，因为它是由服务器发送的（可能以列表的形式）？

import requests
with requests.Session() as s:
    resp = s.get("https://github.com")
    print(resp.cookies)
    #resp.cookies.items()
    #resp.cookies.get_dict()
    # More details: http://docs.python-requests.org/en/master/_modules/requests/cookies/
<RequestsCookieJar[
<Cookie logged_in=no for .github.com/>,
<Cookie _gh_sess=UHd5aUZ0ZXlBVDVPMitaVVBaWFp0c1p6dFA0TWVSanJzRGgrbU1XbVkxV3VXRW9LeWgwWHpWZ2pOOHFxZmtGaTZpRExpT2NjTHRyK3hHZG5GZjlxTzllbklqK0thQytHYi9HZWsrZ1poZ1ZUakJkRU9OZmJINEh3QUR2N3h3UUh6aVdFTmFCRHlHcVpwWHo1bEM5d25adnhUemJ6Y3pFMUxTbk50Q0M0UUJrVG5hR3kxRUVoUTB2TjdUc2hWbHk3cDJDWUZ4UW85NVRuR09keFJRTlc1QT09LS1RUnZHWUpsQ3BQU0hPZGtsWDAxQXFBPT0%3D--d2bd04e94c369f425fb7e9cc57b5b5499909b140 for github.com/>,
<Cookie has_recent_activity=1 for github.com/>]>

它也可以通过正则表达式（regex101_A regex101_B）提取

import requests, re
with requests.Session() as s:
    resp = s.get("https://github.com")
    show_cookie = lambda x: [re.findall(r"([^,;s]*?=.*?(?=;|$))|(w+(?=;|$|,))",cookie) for cookie in re.findall(r"((?:^|,s).*?)(?=,sS+;|$)",x)]
    print(show_cookie(resp.headers.get('Set-Cookie')))
[[('has_recent_activity=1', ''), ('path=/', ''), ('expires=Sat, 29 Dec 2018 14:43:45 -0000', '')], [('logged_in=no', ''), ('domain=.github.com', ''), ('path=/', ''), ('expires=Wed, 29 Dec 2038 13:43:45 -0000', ''), ('', 'secure'), ('', 'HttpOnly')], [('_gh_sess=eHBNWkZscHFMeXJ3NEJUU0VXZlBQaHg0S01rby9MK24xNnFvR3gvVTBsOUJjTWNWenJPZ0RRdk9RNE9ZV2V0MTQ1bTg2NEduY3phSWRrd3l0L252KzBJNkRYZlpjWXh5c2NBZktkWGFsdjZDbEJjTEdhVmZ0YnpldDFHTEpuQzFTcDNNS21sT3BRaHhBVUFqTHQ1cDZyQWNPU005ODY0bFh0MGxCbWI5d2kwait5RlcvVjlUc2FwTTdNRE8wOHZQb0RGak5YbG1ZSDJTM2ZpQmVUUkkrdz09LS11M0ZHem1YYjdWYkVLaWtRMkhscW5nPT0%3D--f778e2d24e96f3386a2da36e2d33d2b73418deed', ''), ('path=/', ''), ('', 'secure'), ('', 'HttpOnly')]]
