console.log和redirect在node.js不起作用？
我申请注册和login，但东西不能正常工作
这是来自routers / users.js的users.js
var express = require('express'); var router = express.Router(); var passport = require('passport'); var LocalStrategy = require('passport-local').Strategy; var multer = require('multer'); var upload = multer({dest: './uploads'}); var User = require('../models/user'); /* GET users listing. */ router.get('/', function(req, res, next) { res.send('respond with a resource'); }); router.get('/register', function(req, res, next) { res.render('register', { 'title': 'Register' }); }); router.get('/login', function(req, res, next) { res.render('login', { 'title': 'Login' }); }); router.post('/register', upload.single('profileimage'), function(req, res, next){ //get form values var name = req.body.name; var email = req.body.email; var username = req.body.username; var password = req.body.password; var password2 = req.body.password2; //check for image field if(req.files && req.files.profileimage){ console.log('Uploading File...'); //var profileimage = req.file.filename; //file info var profileImageOriginalName = req.files.profileimage.originalname; var profileImageName = req.files.profileimage.name; var profileImageMime = req.files.profileimage.mimetype; var profileImagePath = req.files.profileimage.path; var profileImageExt = req.files.profileimage.extension; var profileImageSize = req.files.profileimage.size; } else { //set a default image var profileImageName = 'noimage.png'; } //form validation req.checkBody('name','Name field is required').notEmpty(); req.checkBody('email','Email field is required').notEmpty(); req.checkBody('email','Email not valid').isEmail(); req.checkBody('username','Username field is required').notEmpty(); req.checkBody('password','Password field is required').notEmpty(); req.checkBody('password2','Passwords do not match').equals(req.body.password); //check for errors var errors = req.validationErrors(); if(errors){ res.render('register', { errors: errors, name: name, email: email, username: username, password: password, password2: password2 }); } else { var newUser = new User({ name: name, email: email, username: username, password: password, profileimage: profileImageName }); //create user User.createUser(newUser, function(err, user){ if(err) throw err; console.log(user); }); //success message req.flash('success', 'You are now registered and may log in'); res.location('/'); res.redirect('/'); } }); passport.serializeUser(function(user, done) { done(null, user.id); }); passport.deserializeUser(function(id, done) { User.getUserById(id, function(err, user) { done(err, user); }); }); passport.use(new LocalStrategy( function(username, password, done){ User.getUserByUsername(username, function(err, user){ if(err) throw err; if(!user){ console.log('Unknown User'); return done(null, false, {message: 'Unknown User'}); } User.comparePassword(password, user.password, function(err, isMatch){ if(err) throw err; if(isMatch){ return done(null, user); } else { console.log('Invalid Password'); return done(null, false, {message: 'Invalid Password'}); } }); }); } )); router.post('/login', passport.authenticate('local',{failureRedirect: '/users/login', failureFlash: 'Invalid username or password'}), function(req, res){ console.log('Authentication Successful'); req.flash('success', 'You are logged in'); res.redirect('/'); }); module.exports = router; 这是来自models / user.js的user.js
var mongoose = require('mongoose'); var bcrypt = require('bcrypt'); mongoose.connect('mongodb://localhost/nodeauth'); var db = mongoose.connection; //user schema var UserSchema = mongoose.Schema({ username: { type: String, index:true }, password: { type: String, required: true, bcrypt: true }, email: { type: String }, name: { type: String }, profileimage: { type: String } }); var User = module.exports = mongoose.model('User', UserSchema); module.exports.comparePassword = function(candidatePassword, hash, callback){ bcrypt.compare(candidatePassword, hash, function(err, isMatch){ if(err) return callback(err); callback(null, isMatch); }); } module.exports.getUserById = function(id, callback){ User.findById(id, callback); } module.exports.getUserByUsername = function(username, callback){ var query = {username: username}; User.findOne(query, callback); } module.exports.createUser = function(newUser, callback){ bcrypt.hash(newUser.password, 10, function(err, hash){ if(err) throw err; //set hashed pw newUser.password = hash; //create user newUser.save(callback); }); }
当使用注册时，它可以工作，但是当使用注册不起作用时。 在cmd中具体不会显示我是否正确或不是日志，redirectfunction不起作用。
命令提示
好吧，我有一个快速查看passport文档，它看起来像你的身份validation失败，你会被redirect到passport.authenticate方法的failureRedirect prop中指定的url。
默认情况下， passport.authenticate工作，如果authentication失败， 护照将以401 Unauthorized状态响应，并且不会调用任何其他路由处理程序。 既然你已经给方法指定了一些选项，特别是一个urlredirect的地址， passport做的是redirect而不是响应401 Unauthorized 。 这显示在命令提示符的提供的屏幕上。 首先你得到一个302 Found响应POST /users/login后，你redirect到GET /users/login 。
无论如何，要注意的事实是，如果authentication失败，任何额外的callback将不会被调用。
所以，最有可能的是，你永远不会到达console.log和res.redirect('/'); 因为你从来没有得到authentication。
