如何比较两个json文件并打印差异报表

import json

def compare_json(file1, file2):
    # 读取两个JSON文件
    with open(file1, 'r') as f1, open(file2, 'r') as f2:
        json1 = json.load(f1)
        json2 = json.load(f2)

    # 比较两个JSON数据
    diff = {}
    for key in json1:
        if key not in json2:
            diff[key] = {'status': 'deleted', 'value': json1[key]}
        elif json1[key] != json2[key]:
            diff[key] = {'status': 'modified', 'old_value': json1[key], 'new_value': json2[key]}

    for key in json2:
        if key not in json1:
            diff[key] = {'status': 'added', 'value': json2[key]}

    # 打印差异报表
    for key, value in diff.items():
        if value['status'] == 'deleted':
            print(f"Key '{key}' is deleted. Value: {value['value']}")
        elif value['status'] == 'modified':
            print(f"Key '{key}' is modified. Old value: {value['old_value']}, New value: {value['new_value']}")
        elif value['status'] == 'added':
            print(f"Key '{key}' is added. Value: {value['value']}")

# 示例用法
compare_json('file1.json', 'file2.json')
