当文件中有其他对象时，合并具有公共键值的两个JSON文件

import json

def merge_json_files(file1, file2):
    with open(file1, 'r') as f1, open(file2, 'r') as f2:
        json1 = json.load(f1)
        json2 = json.load(f2)

    merged_json = {}

    # Merge keys from the first JSON file
    for key, value in json1.items():
        if key in json2:
            merged_json[key] = value + json2[key]
        else:
            merged_json[key] = value

    # Add keys from the second JSON file
    for key, value in json2.items():
        if key not in json1:
            merged_json[key] = value

    # Write merged JSON to a new file
    with open('merged.json', 'w') as outfile:
        json.dump(merged_json, outfile)

# Usage
merge_json_files('file1.json', 'file2.json')
