Passport.js本地策略没有猫鼬

Question

I'm trying to find resources about the most simple login with passport for a node app. I mean, using:

middleware:

    app.use(bodyParser.json());
    app.use(bodyParser.urlencoded({extended: false}));
    app.use(cookieParser());

    app.use(session({ secret: 'keyboard cat', resave: false, saveUninitialized: false }));
    app.use(passport.initialize());
    app.use(passport.session());

    app.use(express.static('public'));

passport:

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

passport.deserializeUser(function(id, done) {
    done({ id: id, nickname: "test"})
});


    passport.use(new LocalStrategy(
      function(username, password, done) {
        console.log("test");
          if (username === 'username') {
              return done(null, { name: "test", id: '1234'});
          } else {
              return done(null, false, { message: 'Incorrect cred.' });
          }
      })
    )

and redirection:

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

my app structure:

/app.js
/public/index.html
/public/login.html

And that's it. the Web is full of the same examples of Mongoose with plugins, everyone simply copy-pasting from each other.

The point is that I would like, later on, to insert my own code ti the LocalStrategy code (would probably used LDAP).

Currently, instead of redirecting to /index.html with the page created in the public folder, I just receive [object Object] on index.html.

Answer 1

Your passport.deserializeUser() is incorrect:

passport.deserializeUser(function(id, done) {
  done({ id: id, nickname: "test"})
});

It's passing the "user" object as first argument to done , which is reserved for errors. This causes Express to render an error page where it tries to stringify the error, resulting in [object Object] .

Try this:

passport.deserializeUser(function(id, done) {
  done(null, { id: id, nickname: "test"})
});

Found the issue! the redirection didn't work, so I looked back up and noticed that the express.static mw was set AFTER the passport initialize(), and not BEFORE. I just moved it up to the top and.. rainbows
