如何在json中添加附加值

Question

我有一个json变量，如下所示

json_data=

[
    {
        "authType": "ldap",
        "password": "",
        "permissions": [
            {
                "collections": [
                    "aks9099",
                    "aks9098"
                ],
                "project": "Central Project"
            }
        ],
        "role": "devSecOps",
        "username": "chini.n@example.com"
    }
]

想要将aks9100添加到集合中

预期结果应该如下所示

[
    {
        "authType": "ldap",
        "password": "",
        "permissions": [
            {
                "collections": [
                    "aks9099",
                    "aks9098",
                    "aks9100"
                ],
                "project": "Central Project"
            }
        ],
        "role": "devSecOps",
        "username": "chini.n@example.com"
    }
]

谢谢

Answer 1

下面是一种快速的非动态方法：

import json

json_path = '/Path/To/File.json'
# Open and read file
with open(json_path, 'r') as fin:
    json_data = json.load(fin)

# Open and write to file
with open(json_path, 'w') as fout:
    # Add str to nested list
    json_data[0]['permissions'][0]['collections'].append("aks9100")
    # Use write() and dumps() to maintain the json format
    fout.write(json.dumps(json_data, indent=4))

在上面，我假设您需要更新一个json文件。在json数据中，您有一个带有嵌套字典的列表，以及嵌套在该字典中的另一个列表。[0]获取列表中的第一项，字典键返回各自的值。

要将"aks9100"添加到这个特定的json变量中，您需要使用以下代码：

import json

json_data[0]['permissions'][0]['collections'].append("aks9100")
