将内容从文本文件转换为对象列表 python

Question

我有cookie.txt，内容如下

[
    {
        "domain": "example.com",
        "expirationDate": 1683810439,
        "hostOnly": false,
        "httpOnly": false,
        "name": "__adroll_fpc",
        "path": "/",
        "sameSite": "lax",
        "secure": false,
        "session": false,
        "storeId": null,
        "value": "2123213-1651041941056"
    },
    {
        "domain": "example.com",
        "expirationDate": 1715324838,
        "hostOnly": false,
        "httpOnly": false,
        "name": "_ga",
        "path": "/",
        "sameSite": null,
        "secure": false,
        "session": false,
        "storeId": null,
        "value": "12332.1651041940"
    }
]

我正在尝试访问该 txt 的每个对象，如下所示

def initCookies(self):
        with open('cookie.txt', encoding='utf8') as f:
            cookies = f.readlines()
        mystring = ' '.join([str(item) for item in cookies])

        data = json.loads(mystring)
        print(type(data))

        for cookie in data:
            print(cookie)

但似乎print(cookie) 有完整的内容。

如何访问 {} 中的每个对象？

我应该可以像这样访问它们 cookie.get('name', ''), cookie.get('value', '')

Answer 1

您可以简化您的代码，即使它已经有效...

import json
with open('cookie.txt', encoding='utf8') as f:
  cookies = json.load(f)
for cookie in cookies:
  print(cookie.get("name"))  # '__adroll_fpc', '_ga'

Answer 2

为什么要先将列表转换为大字符串？您可以直接使用 json.load 而不是 json.loads

with open('cookie.txt', encoding='utf8') as f:
    data = json.load(f)
   
data # list of 2 dictionaries

for dic in data:
    print(dic.get('name'))

Output:
__adroll_fpc
_ga
