python - 将 JSON 格式的 cookie 加载到请求中

我从客户端发送了一些 cookie，允许我以编程方式登录他的服务器，而无需凭据。

我正在使用 requests 包向他的服务器发出 HTTP 请求。问题是他发送的 cookie 都是 JSON 格式的，我似乎找不到任何方法来加载这些 cookie。

除了编写一种将它们转换为常规 cookie 的方法之外，是否有任何现有的解决方案来加载这些 cookie？

这是我当前的代码:

def cookieLogin(cookies):

    with open(cookies) as f:
        cookies = requests.utils.cookiejar_from_dict(json.load(f)[0] )

    session = requests.session()
    session.cookies = cookies

    r = session.get('https://example.com')

cookies 示例:

[
{
    "domain": ".example.com",
    "hostOnly": false,
    "httpOnly": false,
    "name": "act",
    "path": "/",
    "sameSite": "no_restriction",
    "secure": false,
    "session": true,
    "storeId": "0",
    "value": "875",
    "id": 1
},
{
    "domain": ".example.com",
    "expirationDate": 1479135421.720188,
    "hostOnly": false,
    "httpOnly": false,
    "name": "c_user",
    "path": "/",
    "sameSite": "no_restriction",
    "secure": true,
    "session": false,
    "storeId": "0",
    "value": "109",
    "id": 2
},
...

错误:

cookies jar :

最佳答案

一种方法是创建一个函数，将所有字典的非字符串值递归地转换为字符串

import requests


session = requests.session()


def stringify(obj: dict) -> dict:
    """turn every value in the dictionary to a string"""
    for k, v in obj.items():
        if isinstance(v, dict):
            # if value is a dictionary, stringifiy recursively
            stringify(v)
            continue
        if not isinstance(v, str):
            if isinstance(v, bool):
                # False/True -> false/true
                obj[k] = str(v).lower()
            else:
                obj[k] = str(v)
    return obj


with open('cookies.json') as f:
    cookie_list: list = json.load(f)
    # create the cookie jar from the first cookie
    cookie_jar = requests.utils.cookiejar_from_dict(stringify(cookie_list[0]))
    # append the rest of the cookies
    for cookie in cookie_list[1:]:
        requests.utils.add_dict_to_cookiejar(cookie_jar, stringify(cookie))
    session.cookies = cookie_jar
