Question

我尝试使用express4 / passportjs设置一个简单的本地策略验证，但永远不会调用authenticate函数：这是我的代码

var passport = require('passport');
var LocalStrategy = require('passport-local').Strategy;
app.use(compress());  
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());

/*  AUTHENTIFICATION */

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


passport.serializeUser(function(user, done) {
  done(null, user);
});

passport.deserializeUser(function(user, done) {
  done(null, user);
});

passport.use(new LocalStrategy(
  function(username, password, done) { //THIS FUNCTION IS NEVER CALLED
    console.log("Local strategy");
  }
));


app.post('/login', function(req, res) {
    console.log("user : ", req.body.username);
    console.log("password : ", req.body.password);
    passport.authenticate('local', { successRedirect: '/',
                                     failureRedirect: '/login' })
});

/*  !AUTHENTIFICATION */

app.use(express.static(path.join(__dirname, 'public')));
app.use(express.static(path.join(__dirname, 'bower_components')));
app.use(express.static(path.join(__dirname, 'controllers')));
app.use(express.static(path.join(__dirname, 'modules')));
app.use('/', routes);
app.use('/users', users);

当我在/ login中发送帖子请求时，我在日志中看到用户名和密码，但password.authentificate方法没有做任何事情。它应该调用LocalStrategy函数和console.log（＆＃39;策略＆＃39;）但它没有。

有人知道如何修复它吗？

由于

来自here的

authenticate()'s function signature is standard Connect middleware。

因此应传递req, res, next的引用

因此您可以将其用作路由中间件

app.post('/login', passport.authenticate('local', { successRedirect: '/',
                               failureRedirect: '/login' }));

或

app.post('/login', function(req, res, next) {
    passport.authenticate('local', { successRedirect: '/',
                                 failureRedirect: '/login' })(req, res, next);
});

从未调用过LocalStrategy函数
