PassportJS events.js：160 //未处理的错误连接超时
我创build了一个MEAN Stack应用程序，最近我join了passportjs，起初当我的Mongo数据库是1GB（它有超过300万个条目）时，一切正常，但是最近数据库增长到了2GB，当护照被称为1 / 3次它在控制台上抛出这个错误：

Please include the following file with any support request: npm ERR! C:\Users\Andre\Desktop\bootcamp\voting-app\npm-debug.log 这是我的App.js：
var express = require('express'); var session = require('express-session') var http = require('http'); var path = require('path'); var favicon = require('serve-favicon'); var logger = require('morgan'); var cookieParser = require('cookie-parser'); var bodyParser = require('body-parser'); var app = express(); var mongoose = require('mongoose'); var passport = require('passport'); var options = {server: {socketOptions: {connectionTimeoutMS: 120000,socketTimeoutMS: 120000}}}; mongoose.connect('mongodb://localhost:27017/mean-database',options, function(err,db){ if (!err){ console.log('Connected to /mean-database!'); } else{ console.dir(err); //failed to connect } }); require('./models/citizens'); require('./config/passport'); require('./models/Candidate'); require('./models/Province'); require('./models/Parties'); var routes = require('./routes/index'); var citizens = require('./routes/citizens'); var candidates = require('./routes/candidates'); var provinces = require('./routes/provinces'); var graphics = require('./routes/graphics'); var parties = require('./routes/parties'); // view engine setup app.set('views', path.join(__dirname, 'views')); app.set('view engine', 'ejs'); app.use(favicon(__dirname + '/public/favicon.ico')); app.use(logger('dev')); app.use(bodyParser.json()); app.use(bodyParser.urlencoded({ extended: false })); app.use(cookieParser()); app.use(express.static(path.join(__dirname, 'public'))); app.use(passport.initialize()); app.use('/', routes); app.use('/users', citizens); app.use('/api', candidates); app.use('/api', provinces); app.use('/api', graphics); app.use('/api', citizens); app.use('/api', parties); // catch 404 and forward to error handler app.use(function(req, res, next) { var err = new Error('Not Found'); err.status = 404; next(err); }); // error handlers // development error handler // will print stacktrace if (app.get('env') === 'development') { app.use(function(err, req, res, next) { res.status(err.status || 500); res.render('error', { message: err.message, error: err }); }); } // production error handler // no stacktraces leaked to user app.use(function(err, req, res, next) { res.status(err.status || 500); res.render('error', { message: err.message, error: {} }); }); module.exports = app;
这是我的“开始”脚本：
var debug = require('debug')('votingApp'); var app = require('../app'); app.set('port', process.env.PORT || 3000); var server = app.listen(app.get('port'), function() { debug('Express server listening on port ' + server.address().port); });
这是我的passport.js文件：
var express = require('express'); var passport = require('passport'); var LocalStrategy = require('passport-local').Strategy; var mongoose = require('mongoose'); var User = mongoose.model('Citizen'); passport.use(new LocalStrategy( function(electoral_code, password, done) { User.findOne({ electoral_code: electoral_code }, function (err, user) { if (err) { return done(err); } if (!user) { return done(null, false, { message: 'Incorrect username.' }); } if (!user.validPassword(password)) { return done(null, false, { message: 'Incorrect password.' }); } return done(null, user); }).maxTime(20000); } ));
我已经尝试过了：重新安装节点，更新所有节点模块，清理caching，重新安装所有模块
编辑：也添加npm-debug.log：

（代表OP发布） 。
我通过索引Mongo数据库来解决这个问题：
db.citizens.ensureIndex({ username: 1, password: 1 })
