标签: connect-flash

快速连接闪存仅在刷新后显示. 代码被剥离以便于阅读.

"express": "~4.2.0",
"connect-flash": "~0.1.1",

这是我的 app.js

var express = require('express'),
    favicon = require('serve-favicon'),
    flash = require('connect-flash');
var app = express();
app.use(cookieParser('---'));
app.use(session({
  secret: '---',
  saveUninitialized: true,
  resave: true}));
app.use(flash());

app.use(function(req, res, next) {
  res.locals.messages = req.flash();
  next();
});

在我的路线我试过像

req.flash('success', {msg: 'Sign Up Success'});
res.redirect('/me/dashboard');

我的错误显示msg.jade模板是

for msg in messages
      div #{msg.msg}

我只是在刷新/ redirtect之后收到消息.请让我知道我做错了什么.

我也看到了这一点,但我觉得它过时了

我在使用connect-flash工作时遇到了一些问题,我得到的错误信息是:

'错误:req.flash()需要会话'

我已经看到这可能是因为应用程序的排序,但我不确定这是否是这种情况.

App.js:

var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var session = require('express-session');
var flash = require('connect-flash');
var passport = require('passport');
var app = express();

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(session({secret: '{secret}', name: 'session_id', saveUninitialized: true, resave: true}));
app.use(passport.initialize());
app.use(passport.session());
app.use(flash());

路线等如下

闪存生成代码:

passport.authenticate('local', { failureRedirect: '/login', successRedirect: '/', failureFlash: true})

当我尝试从页面登录时,我收到了错误return done(null, false, req.flash('loginMessage', 'User does not exist')); TypeError: req.flash is not a function.

以下是我的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 = …

关于flash,connect-flash和express-flash之间究竟有什么区别我还是有点困惑.

安装:

• 闪npm install flash

• 快递:npm install express-flash

• 连接闪存:npm install connect-flash

用法:

闪光:

app.use(session()); // session middleware 
app.use(require('flash')());

app.use(function (req, res) {
  // flash a message 
  req.flash('info', 'hello!');
  next();
})

连接闪存

var flash = require('connect-flash');
var app = express();

app.configure(function() {
  app.use(express.cookieParser('keyboard cat'));
  app.use(express.session({ cookie: { maxAge: 60000 }}));
  app.use(flash());
});

express-flash它甚至要求使用的设置方式与connect-flash相同:

var flash = require('express-flash'),
    express = require('express'),
    app = express();

  app.use(express.cookieParser('keyboard cat'));
  app.use(express.session({ cookie: { maxAge: 60000 }}));
  app.use(flash()); …

我正在学习如何使用nodejs和passport设置身份验证的教程.(http://scotch.io/tutorials/javascript/easy-node-authentication-setup-and-local)

本教程让我使用ejs渲染模板并传入flash数据.

而不是这个,我想使用angularjs.我遇到问题的部分是获取闪存数据.我知道如何使用模板和发送变量,但角度中的内容取代了下面代码中的"req.flash('signupMessage')"？

这是教程显示的代码:

app.get('/signup', function(req, res) {
  // render the page and pass in any flash data if it exists
  res.render('signup.ejs', { message: req.flash('signupMessage') });    
});

这是我设置路线的代码

// public/js/appRoutes.js
angular.module('appRoutes', []).config(['$routeProvider', '$locationProvider', function($routeProvider, $locationProvider) {

$routeProvider

    // show signup form
    .when('/signup', {
        templateUrl: 'views/signup.html',
        controller: 'SignupController'  
    });
$locationProvider.html5Mode(true);

}]);

这是控制器:

 // public/js/controllers/SetupCtrl.js
 angular.module('SignupCtrl', []).controller('SignupController', function($scope) {
     $scope.tagline = 'TEST';
 });

从本示例开始，我正在为节点应用程序进行用户注册，但是使用MySQL数据库而不是MongoDB。用户中的多列表具有唯一性约束。
