在json中剥离尾部空格

import json

def strip_trailing_spaces(json_str):
    # 将JSON字符串解析为Python对象
    data = json.loads(json_str)

    # 递归遍历JSON对象，剥离键和值的尾部空格
    def strip_spaces(obj):
        if isinstance(obj, dict):
            for key, value in obj.items():
                if isinstance(value, str):
                    obj[key] = value.rstrip()
                elif isinstance(value, (dict, list)):
                    strip_spaces(value)
        elif isinstance(obj, list):
            for item in obj:
                strip_spaces(item)

    # 剥离尾部空格
    strip_spaces(data)

    # 将Python对象重新转换为JSON字符串
    stripped_json_str = json.dumps(data)

    return stripped_json_str
