# pip3 install requests
import requests
import json


def get_access_token():
    """
    获取微信全局接口的凭证(默认有效期俩个小时)
    如果不每天请求次数过多, 通过设置缓存即可
    """

        },
        data=bytes(json.dumps(body, ensure_ascii=False), encoding='utf-8')
    )
    # 这里可根据回执code进行判定是否发送成功(也可以根据code根据错误信息)
    result = response.json()
    print(result)



if __name__ == '__main__':
    sendmsg('o2Ifb0va8Xp4zIidu8RYAR57ae-U','你好啊')   #别人关注你才能发消息
