为什么我收到HTTP 400错误？

Question

我发现400 HTTP错误是带语法的东西，但我发现我的语法没有任何问题，有人可以帮忙看一下吗？

<!- My form view-->
<h3>Login</h3>
<form action="/home/login" method="post">
  Enter your usernmae: <input type="text" name="user" value=""><br>
  Enter your password: <input type="password" name="pwd" value=""><br>
  <input type="submit" name="enter" value="Enter">
</form>




//controller added to my app.js
app.use('/home', indexController);




//in router.js
var passport = require('passport');
var LocalStrategy = require('passport-local').Strategy;

router.post('/login', passport.authenticate('local'), function(req, res) {
  req.session.save(function (err) {
    if (err) {
      return next(err);
    }
    res.redirect('/home/' + req.user.user);
  });
});
