有没有什么代码可以用来在JSON中查找完整的案例？

def find_key(json_obj, key):
    result = []
    
    if isinstance(json_obj, dict):
        for k, v in json_obj.items():
            if k == key:
                result.append(json_obj)
            elif isinstance(v, (dict, list)):
                result.extend(find_key(v, key))
    elif isinstance(json_obj, list):
        for item in json_obj:
            result.extend(find_key(item, key))
    
    return result

import json

# 示例JSON对象
json_str = '''
{
    "name": "John",
    "age": 30,
    "address": {
        "street": "123 Street",
        "city": "New York"
    },
    "friends": [
        {
            "name": "Alice",
            "age": 25
        },
        {
            "name": "Bob",
            "age": 35
        }
    ]
}
'''

# 将JSON字符串解析为Python对象
json_obj = json.loads(json_str)

# 查找键为"name"的完整案例
results = find_key(json_obj, "name")

# 打印结果
for result in results:
    print(json.dumps(result, indent=4))
