    String corpid;
    String corpsecret;
 

    String Get_Token_Url;
    String SendMessage_Url;

    public String getCorpid() {
        return corpid;
    }
    public void setCorpid(String corpid) {
        this.corpid = corpid;
    }
    public String getCorpsecret() {
        return corpsecret;
    }

        SendMessage_Url = "https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token=";
        return SendMessage_Url;
    }
}
