python之将 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到他的服务器，而无需凭据。

我正在使用请求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') 

Cookie 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:

请您参考如下方法:

一种方法是创建一个函数，将字典中的所有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
