Python索引必须为整数

Question

我有这段代码，我试图从下面的示例json访问一些文件，我试图弄清楚为什么这个错误不断出现，但是我没有成功。 我究竟做错了什么？ 什么是获取此数据的最佳方法？

def _get_user_map(self):
    user_map = {}
    users = self.get_users().json()
    for user in users:
        user_map[user['person']['id']] = user['person']

    return user_map

样本json

[
    {
        "kind": "account_membership",
        "id": 100,
        "person": {
            "kind": "person",
            "id": 100,
            "name": "Emperor Palpatine",
            "email": "emperor@galacticrepublic.gov",
            "initials": "EP",
            "username": "palpatine"
        },
        "account_id": 100,
        "created_at": "2019-09-03T12:00:00Z",
        "updated_at": "2019-09-03T12:00:00Z",
        "owner": true,
        "admin": false,
        "project_creator": false
    },
    ...
]

我收到以下错误

in _get_user_map
    user_map[user['id']['person']] = user['person']
TypeError: string indices must be integers

Answer 1

您在user_map[user['id']['person']] = user['person']出错，因为此行与您的JSON结构不匹配。 您需要交换“ person”和“ id”，以便您的行读取： user_map[user['person']['id']] = user['person'] 。

Answer 2

我for user in users:修改了此行for user in users:我删除了用户，并for user in "":双引号for user in "":问题已解决
