我在尝试使用Node.js和Passport.js注册时尝试对用户进行身份验证，但每当我调用authenticate方法时，我都会收到错误并说错误：
TypeError: Cannot call method 'authenticate' of undefined at /Users/MarcellusPowell/Desktop/Stake/Code/routes/routes.js:53:13 at Layer.handle [as handle_request] (/Users/MarcellusPowell/Desktop/Stake/Code/node_modules/express/lib/router/layer.js:76:5) at next (/Users/MarcellusPowell/Desktop/Stake/Code/node_modules/express/lib/router/route.js:100:13) at next (/Users/MarcellusPowell/Desktop/Stake/Code/node_modules/express/lib/router/route.js:94:14) at Route.dispatch (/Users/MarcellusPowell/Desktop/Stake/Code/node_modules/express/lib/router/route.js:81:3) at Layer.handle [as handle_request] (/Users/MarcellusPowell/Desktop/Stake/Code/node_modules/express/lib/router/layer.js:76:5) at /Users/MarcellusPowell/Desktop/Stake/Code/node_modules/express/lib/router/index.js:227:24 at Function.proto.process_params (/Users/MarcellusPowell/Desktop/Stake/Code/node_modules/express/lib/router/index.js:305:12) at /Users/MarcellusPowell/Desktop/Stake/Code/node_modules/express/lib/router/index.js:221:12 at Function.match_layer (/Users/MarcellusPowell/Desktop/Stake/Code/node_modules/express/lib/router/index.js:288:3
这是我的 app.js 文件：
var express = require('express');
var morgan = require('morgan');
var bodyParser = require('body-parser');
var cookieParser = require('cookie-parser');
var methodOverride = require('method-override');
var staticFavicon = require('static-favicon');
var session = require('express-session');
var passport = require('passport');
var path = require('path');
var fs = require('fs');
var http = require('http');
var app = express();
// all environments
app.set('port', process.env.PORT || 3000);
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
app.use(morgan('dev'));
app.use(bodyParser());
app.use(cookieParser());
//app.use(express.json());
//app.use(express.urlencoded());
app.use(methodOverride());
//app.use(staticFavicon(path.join(__dirname + '/public/images/favicon.ico')));
app.use(session({
secret: 'moneymaking',
cookie: {
maxAge: 86400000
}
}));
app.use(passport.initialize());
app.use(passport.session());
app.use(express.static(__dirname, '/public'));
require('./routes/routes')(app, fs);
http.createServer(app).listen(app.get('port'), function() {
console.log('Express server listening on port ' + app.get('port'));
});
我在我的routes.js中调用这个方法：
var fs = require ('fs');
var mysql = require('mysql');
var passport = require('passport');
var pool = mysql.createPool({
host : '',
user : '',
password : '',
port : '',
database : ''
})
module.exports = function(app, fs, passport){
app.route('/')
.get(function(req, res, next){
res.redirect("/home");
})
app.route('/home')
.get(function(req, res, next){
res.render('index', {title: 'home'});
})
app.route('/signup')
.get(function(req, res, next){
res.render('signup', {title: 'signup', message: req.sessionmessages});
})
.post(function(req, res, next){
})
app.route('/investor')
.get(function(req, res, next){
res.render('investor', {title: 'signup', message: req.sessionmessages});
})
app.route('/company')
.get(function(req, res, next){
res.render('company', {title: 'Comapny signup', message: req.sessionmessages});
})
.post(function(req, res, next){
passport.authenticate('local-signup', function(err, user, info){
req.session.messages = info.messages;
console.log(req.session.messages);
if(err)
req.session.messages = "Error creating user"
console.log(req.session.messages);
return res.redirect('/home')
})
})
app.route('/about')
.get(function(req, res, next){
res.render('about', {title: 'About Us', message: req.sessionmessages});
})
//app.route('/:var(login)?')
/*
.get(funtction(req, res, next){
if(req.isAuthenticated())
res.redirect("/home");
res.render('login', {title: 'Need a Name', message: req.sessionmessages})
})
.post.(function(req, res, next)){
});
*/
}
我在 passport.js 文件中对用户进行序列化和反序列化：
passport.serializeUser(function(user, done) {
done(null, user);
})
passport.deserializeUser(function(user, done) {
done(null, user);
})
