我试图将这个passport.js示例分解为最基本的元素。我一直收到401（未经授权）的消息，无法弄清楚原因。任何帮助将不胜感激。

I am trying to break down this passport.js example to its most basic elements. I keep getting a 401 (Unauthorized) message and can't figure out why. Any help would be greatly appreciated.

谢谢！

Node.js文件：

Node.js file:

var http = require('http'), express = require('express'), passport = require('passport'), LocalStrategy = require('passport-local').Strategy, flash = require('connect-flash'); var port = process.env.PORT || 8080; passport.serializeUser(function(user, done) { done(null, user); }); passport.deserializeUser(function(obj, done) { done(null, obj); }); passport.use(new LocalStrategy( function(username, password, done) { console.log("LocalStrategy working..."); return done(null, { id: 1, username: 'Joe', password: 'schmo'}); } )); var app = express(); app.configure(function(){ app.use(express.static(__dirname + '/app')); app.use(express.cookieParser('big secret')); app.use(express.bodyParser()); app.use(express.methodOverride()); app.use(express.cookieSession()); app.use(flash()); app.use(passport.initialize()); app.use(passport.session()); app.use(app.router); }); app.get('/', function (req, res) { res.sendfile(__dirname + '/index.html'); }); app.post('/login', passport.authenticate('local'), function (req, res) { console.log("authenticated...."); res.end(); }); app.listen(port);

推荐答案

新express.js的所有用户（4.x与passport.js一起可能会遇到'缺少证书'的麻烦，因为默认情况下不会解析POST数据。要修复它，请安装body-parser npm install body-parser 并在代码中使用：

All users of new express.js (4.x and higher) together with passport.js could experience 'Missing credentials' trouble just because POST data is not parsed by default. To fix it install body-parser npm install body-parser and use in your code:

var bodyParser = require( 'body-parser' ); app.use( bodyParser.urlencoded({ extended: true }) );

来自@ivarni的好点： app.use（bodyParser.urlencoded（{ extended：true}））; 必须在之前注入任何护照中间件。

Good point from @ivarni: app.use( bodyParser.urlencoded({ extended: true }) ); must be placed before injecting any passport middleware.
