如何从一个json中删除另一个json中的转义斜杠？

import json

def remove_escape_slash(json_obj):
    if isinstance(json_obj, dict):
        for key, value in json_obj.items():
            if isinstance(value, str):
                json_obj[key] = value.replace('\\', '')
            elif isinstance(value, (dict, list)):
                remove_escape_slash(value)
    elif isinstance(json_obj, list):
        for index, item in enumerate(json_obj):
            if isinstance(item, str):
                json_obj[index] = item.replace('\\', '')

# 原始JSON字符串
json_str = '{"key1": "value1\\\\", "key2": {"subkey": "subvalue\\\\"}}'

# 解析原始JSON
json_obj = json.loads(json_str)

# 删除转义斜杠
remove_escape_slash(json_obj)

# 重建JSON字符串
result_json_str = json.dumps(json_obj)

print(result_json_str)
