問(wèn)題描述

//dbconf

var mongo = require(’mongo’); //引入mysql模塊 var mongoose = require(’mongoose’); //引入mongoose模塊 var shortid = require(’shortid’);var db = mongoose.connect(’mongodb://127.0.0.1/FBMS’)var Schema = mongoose.Schema;db.connection.on(’error’,function(error){

console.log(error);

})db.connection.on(’open’,function(){

console.log(’open mongoDB’);

})var accountSchema= new Schema({

_id: { type: String, unique: true, ’default’: shortid.generate},username:{type:String ,index:{unique:true}},password:String,avataimgurl:{type:String,default:’’},cellphone:Number,address:String,device:{stuff:String},remarks:String

})

module.exports= mongoose.model(’account’,accountSchema); //連接對(duì)象導(dǎo)出

//account

var dbconf = require(’./dbconf’);//導(dǎo)入dbconf模塊var data={code:’200’,msg:’’,username:’’};var checkAccount={

check:function(_req,_res){ dbconf.find({’username’:’wangpeng’},function(err,results,fields){if(err){console.log('數(shù)據(jù)庫(kù)報(bào)錯(cuò)：'+err);console.log('：'+results);console.log('：'+fields);}});}

}

module.exports = checkAccount;

問(wèn)題解答

問(wèn)題模糊，代碼亂，錯(cuò)誤信息不傳上來(lái)。不知道你想問(wèn)什么。回調(diào)報(bào)錯(cuò)為null，是err？還是results？

這個(gè)問(wèn)題當(dāng)事提問(wèn)的時(shí)候有些急，不好意思啊 ，這個(gè)問(wèn)題現(xiàn)在是這樣 ，如果連接到數(shù)據(jù)庫(kù)但是沒(méi)有找到集合或者文檔 回調(diào)err會(huì)顯示null嗎？我的模型導(dǎo)出為module.exports= mongoose.model(’account’,accountSchema); 但是在mongodb中建的集合的名稱為accounts 這個(gè)是mongose自己加上的嗎？
