递归地提取嵌套的json键

def extract_json_keys(data):
    keys = []
    if isinstance(data, dict):
        for key, value in data.items():
            keys.append(key)
            if isinstance(value, (dict, list)):
                keys.extend(extract_json_keys(value))
    elif isinstance(data, list):
        for item in data:
            keys.extend(extract_json_keys(item))
    return keys

# 示例数据
json_data = {
    "name": "John",
    "age": 30,
    "address": {
        "street": "123 Main St",
        "city": "New York",

        {
            "name": "Alice",
            "age": 28

        {
            "name": "Bob",
            "age": 32
        }
    ]
}

# 提取JSON键
keys = extract_json_keys(json_data)
print(keys)

['name', 'age', 'address', 'street', 'city', 'state', 'friends', 'name', 'age', 'name', 'age']
