关于async/await的疑问

Question

希望等待一步操作完成之后，再往下执行为啥这个不行asyncfunctionf(mysql_con){awaitmysql_con.query("select*fromstu_detailwherestu_no=?",['2015130'],asyncfunction(err,result,fields){console.log(result)console.log(q.sql)if(result.length==0){console.log("数据为空");awaitmysql_con.query("insertintostu_detailset?",{stu_no:"2015130"},function(err,result,fields){console.log(a.sql)if(err){console.log(err)}console.log("charu")console.log(result)})}else{awaitmysql_con.query("updatestu_detailset?",{stu_name:"陈翰轩"});}for(vari=0;i

Answer 1

await明显不是这样用的。
awaitfunction1
而不是awaitfunction1(function(){})
如果function1不是返回的Promise,那么你用await肯定没效果
                            

Answer 2

我使用了bluebird这个包
constbluebird=require('bluebird');
asyncfunctionf(mysql_con){
constquery=bluebird.promisify(mysql_con.query.bind(mysql_con));
constresult1=awaitquery('XXX');
constresult2=awaitquery('XXX');
console.log(result1,result2)
}
