我想在mongoose插入成功后返回一個(gè)json，并以res.json(data)的形式發(fā)送給前端，但insert()函數(shù)這樣寫不對(duì)？為什么insert.jsvarUser=require("../mongo/user.js");functioninsert(data){console.log("傳入的data",data)letresult={}varuser=newUser({username:data.username,//用戶賬號(hào)userpwd:data.psw,//密碼//userage:37,//年齡logindate:newDate()//最近登錄時(shí)間});letsaveStatue=user.save(function(err,res){console.log("userSave")if(err){console.log("Error:"+err);result={msg:"success"}//result=res}else{console.log("插入成功")console.log("Res:"+res);result={msg:"success"}//result=res}});console.log("saveStatue",saveStatue)//returnresult//我想insert這個(gè)函數(shù)返回一個(gè)插入成功或失敗的json}//insert();module.exports=insertapp.js我的insertResult想得到一個(gè)插入成功或失敗的json，但是這個(gè)執(zhí)行結(jié)果好想是個(gè)promise對(duì)象app.get("/wechat/login",function(req,res,next){console.log(123)letuser=req.queryconsole.log("帶過來的參數(shù)",user)//console.log(insert.toString())if(user){res.set({"Access-Control-Allow-Origin":"*","Access-Control-Allow-Methods":"POST,GET","Access-Control-Allow-Credentials":"true"});//letfindResult=find(user.username)//console.log("上面是find結(jié)果",findResult)letinsertResult=insert({username:user.userName,psw:user.psw})console.log('insertResult',insertResult)res.json({status:1})}})
