Question

首先，我对Passport.js很新，所以这可能最终成为一个非常天真的问题。我有这个作为注册的策略：

// Configuring Passport
var passport = require('passport');
var expressSession = require('express-session');
var LocalStrategy = require('passport-local').Strategy;
var FacebookStrategy = require('passport-facebook');
app.use(expressSession({secret: 'mySecretKey'}));
app.use(passport.initialize());
app.use(passport.session());
app.use(flash());

//[...]

  passport.use('signup', new LocalStrategy({
     name : 'name',
     password : 'password',
     email : 'email',
     passReqToCallback : true 
   },
   function(req, username, password, done) {
     findOrCreateUser = function(){
       // find a user in Mongo with provided username
       User.findOne({'name':username},function(err, user) {
         // In case of any error return
         if (err){
           console.log('Error in SignUp: '+err);
           return done(err);
         }
        // already exists
      if (user) {
            console.log('User already exists');
            return done(null, false,
            req.flash('message','User Already Exists'));
         } else {
           // if there is no user with that email
           // create the user
           var newUser = new User();
           // set the user's local credentials
           newUser.name = name;
           newUser.password = createHash(password);
           newUser.email = req.param('email');
           /*newUser.firstName = req.param('firstName');
           newUser.lastName = req.param('lastName');*/

           // save the user
           newUser.save(function(err) {
             if (err){
               console.log('Error in Saving user: '+err);
               throw err;
             }
             console.log('User Registration succesful');
             return done(null, newUser);
           });
         }
       });
    };

    // Delay the execution of findOrCreateUser and execute
    // the method in the next tick of the event loop
    process.nextTick(findOrCreateUser);
  })
 );

这就是我在POST上处理/register的方式：

/* Handle Registration POST */
app.post('/register', passport.authenticate('signup', {
  successRedirect: '/',
  failureRedirect: '/failure_registration',
  failureFlash : true
}));

此总是将我带到failureRedirect链接，而不是成功。输入数据是正确的，我总是使用不同的用户和邮件进行注册。如果这是一个愚蠢的问题，我很抱歉，但我真的不明白为什么它永远不会进入successRedirect。

感谢。

编辑：添加@robertklep的建议和更正，仍然没有工作。我想指出没有触发错误，也没有打印任何日志。

EDIT2：序列化/反序列化功能：

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

passport.deserializeUser(function(id, done) {
    User.findById(id, function (err, user) {
        done(err, user);
    });
});

Answer 1

I had this same problem, failureRedirect was always being executed

First to diagnose, I used the custom callback method http://passportjs.org/docs/authenticate

app.post('/sign_in', function(req, res, next) {
    console.log(req.url);
    passport.authenticate('local-login', function(err, user, info) {
        console.log("authenticate");
        console.log(err);
        console.log(user);
        console.log(info);
    })(req, res, next);
});

Then I could see what the hidden error was

authenticate
null
false
{ message: 'Missing credentials' }

Which then became easy for me to diagnoise, I was sending JSON in the request rather than FORM fields

Fixed by changing

app.use(bodyParser.urlencoded({ extended: true }));

To

app.use(bodyParser.json());

Answer 2

你使用http或https吗？我有同样的情况。我修好了这个

app.use(expressSession({....   
   cookie: {
   httpOnly: true,
   secure: false // for http and true for https
 }
}));

在我看来，护照无法收到cookies。

我知道这已经快4岁了，但是如果有人遇到相同的问题，我使用了djeeg的诊断

app.post('/sign_in', function(req, res, next) {
    console.log(req.url);
    passport.authenticate('local-login', function(err, user, info) {
        console.log("authenticate");
        console.log(err);
        console.log(user);
        console.log(info);
    })(req, res, next);
});

我得到：空值假 “缺少凭据”

解决方案：事实证明，我没有在HTML表单中使用“名称”，这意味着未读取数据，这就是错误的出处

<input name="email" type="email">

那为我解决了

尝试检查你的表单的方法，它必须是method = post，以防我错误地把它写成GET方法，我花了3天时间才找到这个，因为没有错误

Passport.js总是执行“failureRedirect”
