Question

我正在尝试使用护照模块在我的网络应用上建立一个Twitter连接

我已按照以下方式实施：

App.js文件：

 /**
 * Module dependencies.
 */
var express     = require('express');
var user        = require('./server/routes/user');
var http        = require('http');
var path        = require('path');
var app         = express();
var passport    = require('passport');
var flash       = require('connect-flash');

require('./server/config/passport')(passport); // pass passport for configuration

// all environments
app.set('port', process.env.PORT || 3000);
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');

app.configure(function() {

    app.use(express.favicon());
    app.use(express.logger('dev'));
    app.use(express.json());
    app.use(express.urlencoded());
    app.use(express.methodOverride());
    app.use(app.router);
    app.use(require('stylus').middleware(path.join(__dirname, 'public')));
    app.use(express.static(path.join(__dirname, 'public')));

    // set up our express application
    app.use(express.logger('dev')); // log every request to the console
    app.use(express.cookieParser()); // read cookies (needed for auth)
    app.use(express.bodyParser()); // get information from html forms

    app.set('view engine', 'ejs'); // set up ejs for templating

    // required for passport
    app.use(express.session({ secret: 'SECRET' })); // session secret
    app.use(passport.initialize());
    app.use(passport.session()); // persistent login sessions
    app.use(flash()); // use connect-flash for flash messages stored in session

});


// // routes ======================================================================
require('./server/routes/index')(app, passport); // load our routes and pass in our app and fully configured passport

我正在使用express.session，但在尝试进行身份验证时收到以下错误消息：

Error: OAuthStrategy requires session support. Did you forget app.use(express.session(...))?

有谁知道我为什么会这样做？

Answer 1

加载的Express中间件的顺序不对。试试这个：

// ...

app.configure(function() {
  app.use(express.favicon());
  app.use(express.logger('dev'));
  // The following two middlwares are NOT necessary because bodyParser includes them.
  // app.use(express.json());
  // app.use(express.urlencoded());
  app.use(express.methodOverride());

  app.use(express.cookieParser()); // read cookies (needed for auth)
  app.use(express.bodyParser()); // get information from html forms
  // required for passport
  app.use(express.session({ secret: 'SECRET' })); // session secret
  app.use(passport.initialize());
  app.use(passport.session()); // persistent login sessions
  app.use(flash()); // use connect-flash for flash messages stored in session

  app.use(app.router);
  app.use(require('stylus').middleware(path.join(__dirname, 'public')));
  app.use(express.static(path.join(__dirname, 'public')));
});

// ...

对于4.0，这有点改变。

首先，您需要先安装express-session然后再定义路线：

// Authentication configuration
app.use(session({
  resave: false,
  saveUninitialized: true,
  secret: 'bla bla bla' 
}));

你可以在后面做OAuth事情：

// Passport
app.use(passport.initialize());
app.use(passport.session());

passport.use(new TwitterStrategy({
   ...
));

Answer 3

如果您使用的是最新快递（3.0）用以下内容替换cookie解析器行：

app.use（express.cookieParser（ “thissecretrocks”））;

为我做同样的错误!!

Answer 4

只需将express-session添加到主js文件中即可。

const session = require('express-session');
// After you declare "app"
app.use(session({ secret: 'melody hensley is my spirit animal' }));

就像这些人为LinkedIn commit做的那样。

显然不要忘记安装express-session，所以npm install express-session或将"express-session": "^1.15.3"添加到您的package.json
