如何使用所有参数通过测试 a json 进行验证? Python

How can I validate with a test a json with all the parameters? Python

示例: { “名字”:“乔斯琳”, “年龄”:30 } 和它 returns 一样。如果有人添加更多参数,它会失败。

我的理解是正确的,你可以写一个这样的函数(检查关键字)

import json

def check_json_data(json_str):
    # base key list
    base_keys = json.loads('{ "name": "Jocelyne", "age": 30 }').keys()
    # convert json string to dict
    input_json_data = json.loads(json_str)
    # extract keys
    input_keys = input_json_data.keys()
    # check if there are additional keys in incoming keys
    if set(input_keys) - set(base_keys): # for exact check of key list: set(input_keys) != set(base_keys)
        return None
    else:
        return json_str

测试

print(check_json_data('{ "name": "Jocelyne", "age": 30, "age2": 30 }'))

print(check_json_data('{ "name": "Jocelyne", "age2": 30 }'))

print(check_json_data('{ "name": "Jose", "age": 33 }'))

None

{ "name": "Joce", "age": "33" }
