//我的报错代码：
    Consigne:function (prompapi,s_province,s_city,s_county,xxdz,phones,yourname,callback) {
        console.log(prompapi,s_province,s_city,s_county,xxdz,phones,yourname);
        //参数：收货人,省,市,县,详细地址,电话号码,用户
        //表：用户ID,具体地址,创建时间,是否删除,省,市,县,收货人,电话号码
        let sql = 'insert into address (userID,Specificaddress,createTime,isdelete,province,city,county,consignee,telephoneNumber) value((select userID from user where userName = ?),?,"2018-7-13",0,?,?,?,?,?)';
        db.connect(sql,[yourname,xxdz,s_province,s_city,s_county,prompapi,phones],callback);
