在通过护照实例的快速路由中路由分离
我正在尝试将用户login模块添加到节点中的现有应用程序。 它使用单独的路由文件为每个模块和一个主路由文件使用最终在server.js中使用的所有子路由当我尝试将passport实例传递给用户路由时，由于未定义passport，因此导致错误。 这里是我的应用程序代码和结构：
app views user index.ejs login.ejs signup.ejs profile.ejs routes docs index.js user index.js index.js config passport.js server.js server.js
const express = require('express') const app = express() const path = require('path') const bodyParser = require('body-parser') const cookieParser = require('cookie-parser') const passport = require('passport') const flash = require('connect-flash') const session = require('express-session') const routes = require('./routes/') const port = process.env.PORT || 3000; app.use(express.static(path.join(__dirname, 'public'))); require('./config/passport')(passport); app.use(bodyParser.urlencoded({ extended: true })); app.use(cookieParser()); app.use(bodyParser.json()); app.set('view engine', 'ejs'); app.set('views', path.join(__dirname, 'views')); app.use(session({ secret: '********' })); app.use(passport.initialize()); app.use(passport.session()); app.use(flash()); app.use('/', routes)(app,passport); const server = app.listen(port, function(){ console.log('Server listening on port '+port); });
configuration/ passport.js
var LocalStrategy = require('passport-local').Strategy; const sql = require('mssql') const bcrypt = require('bcrypt-nodejs') module.exports = function(passport) { passport.serializeUser(function(user, done) { done(null, user); }); passport.deserializeUser(function (username, done) { done(null,username); }); passport.use('local-signup', new LocalStrategy({ usernameField : 'email', passwordField : 'password', passReqToCallback : true }, function(req, email, password, done) { process.nextTick(function() { var strSQL = "SELECT count(id) as uCount FROM <tbl> WHERE username = '"+email+"'"; var cb1 = function(err,recordset){ if(recordset[0].uCount>0){ return done(null, false, req.flash('signupMessage', 'That email is already taken.')); } else{ var strSQL1 = "INSERT INTO <tbl>(username, password) VALUES('"+email+"','"+generateHash(password)+"')"; var cb2 = function(err,recordset){ return done(null, recordset,req.flash('signupMessage', 'Email registered successfully.')); }; executeQuery(strSQL1,'INSERTION','<tbl>',cb2); } }; executeSelection(strSQL,'SELECTION','<tbl>',cb1); }); })); passport.use('local-login', new LocalStrategy({ usernameField : 'email', passwordField : 'password', passReqToCallback : true }, function(req, email, password, done) { var strSQL = "SELECT a.count, id, username, password FROM <tbl> c , (SELECT COUNT(dbid) count FROM <tbl> b WHERE b.username = '"+email+"' ) a WHERE c.username = '"+email+"'"; var cb1 = function(err,recordset){ if(recordset[0].uCount <= 0){ return done(null, false, req.flash('loginMessage', 'No user found.')); } if (!validPassword(password,recordset[0].password)) return done(null, false, req.flash('loginMessage', 'Oops! Wrong password.')); return done(null, recordset[0]); }; executeSelection(strSQL,'SELECTION','<tbl>',cb1); })); }; executeSelection = function(strSQL, operationType, tableName, cb){ var request = new sql.Request(connection); request.query(strSQL,function(err,recordset) { if(err){ logger.error('ERROR in '+operationType+' ON '+tableName+': '+err); } logger.info(operationType+' ON '+tableName+' successful!'); cb(err,recordset); }); }; executeQuery = function(strSQL, operationType, tableName, cb,validateClient) { var request = new sql.Request(connection); request.query(strSQL,function(err, recordset) { if(err){ logger.error('ERROR in '+operationType+' ON '+tableName+': '+err); } logger.info(operationType+' ON '+tableName+' successful!'); if(cb){ cb(validateClient); } }); }; generatePasswordHash = function(password) { return bcrypt.hashSync(password, bcrypt.genSaltSync(8), null); }; validatePassword = function(curPass, dbPass) { return bcrypt.compareSync(curPass, dbPass); };
路线/ index.js
const mainroute = require('express').Router() /* ---- other existing routes included ---- */ const r_docs = require('./docs') const r_user = require('./user') /*my custom route*/ /* ---- all other routes ---- */ mainroute.use('/docs', r_docs); mainroute.use('/user', r_user)(app, passport); /*my custom route*/ mainroute.get('/', function(req, res){ res.render('home'); }); module.exports = function(app, passport){ mainroute; }
路由/用户/ index.js
const express = require('express') const router = express.Router() router.get('/', function(req, res) { res.render('user/index.ejs'); }); router.get('/login', function(req, res) { res.render('user/login.ejs', { message: req.flash('loginMessage') }); }); // process the login form router.post('/login', passport.authenticate('local-login', { successRedirect : '/profile', failureRedirect : '/login', failureFlash : true })); router.get('/signup', function(req, res) { res.render('user/signup.ejs', { message: req.flash('signupMessage') }); }); router.post('/signup', passport.authenticate('local-signup', { successRedirect : '/profile', failureRedirect : '/signup', failureFlash : true })); router.get('/profile', isLoggedIn, function(req, res) { res.render('user/profile.ejs', { user : req.user }); }); router.get('/logout', function(req, res) { req.logout(); res.redirect('/'); }); function isLoggedIn(req, res, next) { if (req.isAuthenticated()) return next(); res.redirect('/'); } module.exports = function(app, passport) { router; }
请build议我在这里做错了什么。 谢谢
你应该包装你的main和user路线来运行他们的逻辑，当你打电话给他们，并在最后返回准备好的路线：
路线/ index.js
module.exports = function(app, passport) { const mainroute = require('express').Router() /* ---- other existing routes included ---- */ const r_docs = require('./docs'); const r_user = require('./user'); /*my custom route*/ /* ---- all other routes ---- */ mainroute.use('/docs', r_docs); mainroute.use('/user', r_user)(app, passport); /*my custom route*/ mainroute.get('/', function(req, res) { res.render('home'); }); return mainroute; };
路由/用户/ index.js
module.exports = function(app, passport) { const express = require('express'); const router = express.Router(); router.get('/', function(req, res) { res.render('user/index.ejs'); }); router.get('/login', function(req, res) { res.render('user/login.ejs', { message: req.flash('loginMessage') }); }); // process the login form router.post('/login', passport.authenticate('local-login', { successRedirect: '/profile', failureRedirect: '/login', failureFlash: true })); router.get('/signup', function(req, res) { res.render('user/signup.ejs', { message: req.flash('signupMessage') }); }); router.post('/signup', passport.authenticate('local-signup', { successRedirect: '/profile', failureRedirect: '/signup', failureFlash: true })); router.get('/profile', isLoggedIn, function(req, res) { res.render('user/profile.ejs', { user: req.user }); }); router.get('/logout', function(req, res) { req.logout(); res.redirect('/'); }); function isLoggedIn(req, res, next) { if (req.isAuthenticated()) return next(); res.redirect('/'); } return router; };
你需要在你的user / index.js的顶部。 只是：
var passport = require('passport');
然后确保用户通过身份validation：
router.get('/some/path', isLoggedIn, function(req, res) { var user = req.user; }); function isLoggedIn(req, res, next) { if (req.isAuthenticated()) return next(); res.redirect('/'); }
