查看字符串是否在json文件中，然后获取它周围的内容

import json

def find_string_in_json(json_file, target_string):
    with open(json_file, 'r') as file:
        json_data = json.load(file)
    
    def search_json(data, target):
        if isinstance(data, dict):
            for key, value in data.items():
                if isinstance(value, str) and target in value:
                    # 目标字符串存在于当前值中，可以获取周围内容
                    # 这里只是简单示例，可以根据具体需求进行处理
                    print("Found target string:", value)
                    print("Surrounding content:", data)
                elif isinstance(value, (dict, list)):
                    search_json(value, target)
        elif isinstance(data, list):
            for item in data:
                search_json(item, target)
    
    search_json(json_data, target_string)

# 示例调用
find_string_in_json('example.json', 'target_string')
