如何反序列化包含更多JSON字符串的JSON？

import json

def deserialize_json_with_nested(json_str):
    data = json.loads(json_str)

    def deserialize_nested(obj):
        for key, value in obj.items():
            if isinstance(value, str):
                try:
                    obj[key] = json.loads(value)
                except ValueError:
                    pass
            elif isinstance(value, dict):
                deserialize_nested(value)

    deserialize_nested(data)
    return data

# 示例JSON字符串
json_str = '''
{
    "name": "John",
    "age": 30,
    "details": "{\"address\": \"123 Main St\", \"city\": \"New York\"}",
    "contacts": [
        "{\"type\": \"email\", \"value\": \"john@example.com\"}",
        "{\"type\": \"phone\", \"value\": \"555-1234\"}"
    ]
}
'''

# 反序列化包含更多JSON字符串的JSON
deserialized_data = deserialize_json_with_nested(json_str)

# 打印反序列化后的结果
print(deserialized_data)
