'use strict';function doSQL(sql) { let mysql = require('mysql'); let row = 'unfinished'; let connection = mysql.createConnection({ host: 'localhost', user: 'root', password: 'abcde1234', database: 'user' }); connection.connect(); connection.query(sql, function (err, rows) { //这里总是在return之后执行 row=rows; connection.end(); }); return row;// 返回 unfinished}module.exports=doSQL;是不是应该用generator async 什么的?(要是有多种方法更好啦~ 谢谢
