Auth :: attempt（）始终返回false

Question

我修改了代码以满足您的建议，但不起作用：

public function login(){
    $credentials = [
        'email' => \Input::get('email'),
        'pass' => \Input::get('pass')
    ];
    if (\Auth::attempt($credentials)) {
        return "Logged In";
    }
    // return \Redirect::to('/User/login');
    return "No Logged In";
}
