Laravel陷入了身份验证循环

Question

I am stuck in an authentication loop, and for the life of me cannot understand why.

Route::get('/', function()
{
    return View::make('hello');
    //return 'Hello ' . Auth::user()->first_name . '!';
});

Route::get('/login', function() {
    return View::make('login'); 
});

Route::post('/login', function() {

    // @TODO: Validate the login details!

    Auth::attempt(array(
        'email' => Input::get('email'),
        'password' => Input::get('password')
        ));

    return Redirect::to('/');
});


Route::group(array('before' => 'auth'), function() {

    Route::get('/home', function()
    {
        //return View::make('hello');
        return 'Hello ' . Auth::user()->first_name . '!';
    });


    /*
    |--------------------------------------------------------------------------
    | API Route Handlers
    |--------------------------------------------------------------------------
    |
    | The API Routes.
    |
    */

    Route::group(array('prefix' => 'api/v1'), function() {

        Route::resource('events', 'EventsController');

    });

});

Here is the sequence of events:

I go to localhost:8000/home it works and redirects me to /login.

I then move on to log in.

It redirects me to the / if I then go to /home it still takes me to /login

Ideal case:

Go to /home only to be redirected to /login

I log in then.

It redirects me to /

I can then move freely between / and /home without the worry of logging in.

            $table->string('password');

            $table->string('first_name');
            $table->string('last_name');
            $table->string('id_number')->unique();

            $table->enum('user_type', array('option 1', 'option 2', 'option 3'));

            $table->rememberToken();

            $table->timestamps();
        });
    }

    /**

     */
    public function down()
    {
        Schema::drop('users');
    }

Fixed it - The problem was that Auth::attempt()'s value wasn't being set.

Here is my new updated version of the code.

Route::get('/', function()
{
    return View::make('hello');
    //return 'Hello ' . Auth::user()->first_name . '!';
});

Route::get('/login', function() {
    return View::make('login'); 
});

Route::post('/login', function() {

    // @TODO: Validate the login details!

    $valid = Auth::attempt(array(
        'email' => Input::get('email'),
        'password' => Input::get('password')
        ));

    if ($valid)
    {
        return Redirect::to('/home');
    } 
    else 
    {
        return Redirect::to('/');
    }

});


Route::group(array('before' => 'auth'), function() {

    Route::get('/home', function()
    {
        //return View::make('hello');
        return 'Hello ' . Auth::user()->first_name . '!';
    });


    /*
    |--------------------------------------------------------------------------
    | API Route Handlers
    |--------------------------------------------------------------------------
    |
    | The API Routes.
    |
    */

    Route::group(array('prefix' => 'api/v1'), function() {

        Route::resource('events', 'EventsController');

    });

});
