如何在JSON中按嵌套字段进行搜索

def search_nested_fields(json_obj, search_key):
    results = []

    def search(json_obj, search_key, current_path=''):
        if isinstance(json_obj, dict):
            for key, value in json_obj.items():
                new_path = current_path + '.' + key if current_path else key
                if key == search_key:
                    results.append({
                        'path': new_path,
                        'value': value
                    })
                search(value, search_key, new_path)
        elif isinstance(json_obj, list):
            for index, item in enumerate(json_obj):
                new_path = current_path + '[' + str(index) + ']'
                search(item, search_key, new_path)

    search(json_obj, search_key)
    return results

import json

# 示例JSON对象
json_str = '''

    "name": "John",
    "age": 30,

        "street": "123 Main St",

        },

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

# 搜索嵌套字段
results = search_nested_fields(json_obj, 'name')

# 打印搜索结果
for result in results:
    print('Path:', result['path'])
    print('Value:', result['value'])
    print('---')
