初入koa2 -连接数据库(遇到的坑之一)

const Client = require("mysql-pro");
const client = new Client({     
    mysql: {
          user: ‘root‘,
          password: ‘root‘,
          database: ‘test‘,
          host: ‘127.0.0.1‘,
    }
}); 

module.exports = client;

const router = require(‘koa-router‘)()
const sql = require(‘../sql/config‘)

router.post(‘/getPerson‘, async (ctx, next) => {
  let data = {
    name: ctx.request.body.name,
    createdAt: Date.now()
  };

  if(!data.name) return;
　// 注意这里，因为是异步，所以要这样写才可以取到值。
  var tmp = await sql.query("select * from _mysql_peoples_info where name = ?;", [data.name]).then(function(result) {
    console.log(result);
    return result;
  }, function(error){
    return -1;
  });
   
   ctx.body = tmp;
})
