如何使用点符号将JSON转换为键列表

def json_to_key_list(json_obj, parent_key='', key_list=[]):
    if isinstance(json_obj, dict):
        for k, v in json_obj.items():
            if parent_key:
                new_key = f"{parent_key}.{k}"
            else:
                new_key = k
            json_to_key_list(v, new_key, key_list)
    elif isinstance(json_obj, list):
        for i, v in enumerate(json_obj):
            new_key = f"{parent_key}[{i}]"
            json_to_key_list(v, new_key, key_list)
    else:
        key_list.append(parent_key)

# 示例JSON对象
json_obj = {
    "name": "John",
    "age": 30,
    "address": {
        "street": "123 Main St",
        "city": "New York"
    },
    "hobbies": ["reading", "coding", "gaming"]
}

key_list = []
json_to_key_list(json_obj, '', key_list)
print(key_list)

['name', 'age', 'address.street', 'address.city', 'hobbies[0]', 'hobbies[1]', 'hobbies[2]']
