当我尝试从页面登录时，出现错误return done(null, false, req.flash('loginMessage', 'User does not exist')); TypeError: req.flash is not a function。
下面是我的 server.js 和 passport.js 配置：
server.js：
var express = require('express');
var app = express();
var bodyParser = require('body-parser');
var methodOverride = require('method-override');
var session = require('express-session');
var ejs = require('ejs');
var mongoose = require('mongoose');
var passport = require('passport');
var flash = require('connect-flash');
mongoose.connect('mongodb://localhost:mydb');
require('./config/passport')(passport);
app.use(express.static('public'));
app.set('view engine', 'ejs');
app.set('views', __dirname+'/public/views');
app.use(bodyParser.urlencoded({'extended':'true'}));
app.use(bodyParser.json());
app.use(methodOverride());
app.use(session({secret:'learningpassport',
resave: true,
saveUnitialized: true}));
app.use(passport.initialize());
app.use(passport.session());
app.use(flash());
require('./app/routes')(app,passport);
app.listen(3000);
配置/passport.js：
var LocalStrategy = require('passport-local').Strategy;
var User = require('../app/model/user');
module.exports = function(passport){
passport.serializeUser(function(user, done){
done(null,user.id);
});
passport.deserializeUser(function(id, done){
User.findById(id, function(err,user){
done(err, user);
});
});
passport.use('local-signup', new LocalStrategy({
usernameField: 'username',
passwordField: 'password',
passReqToCallback: true
},
function(req,username, password, done){
process.nextTick(function(){
User.findOne({'local.username': username}, function(err, user){
if(err) return done(err);
if(user)
return done(null, false, req.flash('signupMessage','The username already exists' ));
else{
var newUser = new User();
newUser.local.username = username;
newUser.local.password = newUser.generateHash(password);
newUser.save(function(err){
if(err) throw done(err);
return done(null, newUser);
});
}
});
});
}));
passport.use('local-login', new LocalStrategy({
usernameField: 'username',
passwordField: 'password',
passReqToCallBack: true
},function(req,username, password, done){
process.nextTick(function(){
User.findOne({'local.username': username}, function(err,user){
if(err) return done(err);
if(!user){
console.log(req.flash);
return done(null, false, req.flash('loginMessage', 'User does not exist'));
}
if(!user.validPassword(password)){
return done(null,false, req.flash('loginMessage', 'Password is not correct'));
}
return done(null, user);
});
});
}));
};
我真的很感谢大家的帮助！！！
登录服务.config.js
'use strict';
angular.module('loginservice').factory('lgservice',function($http){
var myservice = {
async: function(username, password){
var promise = $http.post('/login',{
username: username,
password: password
}).then(function(response){
return response;
});
return promise;
}
};
return myservice;
});
