laravel 4未定义索引：密码

Question

我的代码以前可以正常工作，但现在出现错误

(ErrorException (E_NOTICE)未定义索引：密码)

我真的不知道为什么，所以如果你知道请帮助我。我在谷歌上搜索了类似的异常并尝试了我看到的所有内容，但仍然没有成功......这是我的代码

路由.php

Route::resource('login', 'LoginController');

登录控制器

        public function store(){

        /*$credentials = array(
            'username' => Input::get('username'),
            'password' => Hash::make(Input::get('password')),
        );*/

        if(Auth::attempt(['active' => 1])) {

           // if(Auth::attempt($credentials)){

            if(Auth::attempt(Input::only('username', 'password'))){

                return Auth::user();
                //return Redirect::back()->with('message','You are now logged in!');
                //return Redirect::to('/')->with('message','You are now logged in!');
            }
            else{
                //$errors = ['password' => "Username and/or password invalid."];
               //return Redirect::back()->withErrors($errors)->withInput(Input::except('password'));
                return 'Failed~';
            }
        }
        else{
            //$errors = ['password' => "Please check your email to activate your account"];
            //return Redirect::back()->withErrors($errors)->withInput(Input::except('password'));
            return 'Failed~';
        }
    }
}

查看登录/create.blade.php

@section('content')
    <div class="col-lg-3"></div>
    <div class="form col-lg-6 box">

      {{ Form::open(['route' => 'login.store'], array('class' => 'form-horizontal')) }}

     {{--  @if ($error = $errors->first('password'))
            <div class="alert alert-danger">
                {{ $error }}
            </div>
        @endif--}}

Answer 1

如下重写你的代码。

$username = Input::get('username');
$password = Input::get('password');
// You also may add extra conditions to the authenticating query
if (Auth::attempt(array('username' => $username, 'password' => $password, 'active' => 1)))
{
    // The user is active, not suspended, and exists.
}else{
    // user not exist or suspended
}

也请参考link。

Answer 2

问题是属于您的类提供者EloquentUserProvider 的validateCredentials 方法期望$credentials 数组具有名为password 的数组元素，并期望它被散列。

如图here：

/**
* Validate a user against the given credentials.
*
* @param  \Illuminate\Contracts\Auth\Authenticatable  $user
* @param  array  $credentials
* @return bool
*/
public function validateCredentials(UserContract $user, array $credentials)
{
    $plain = $credentials['password'];
    return $this->hasher->check($plain, $user->getAuthPassword());
}

而你在你的代码中在第一次尝试调用时发送了错误的数组

if(Auth::attempt(['active' => 1]))

要解决这个问题，您可能需要像这样重写代码，

public function store()
{
    $credentials = array(
        'username' => Input::get('username'),
        'password' => Hash::make(Input::get('password')),
        'active' => 1
    );

    if(Auth::attempt($credentials)) {
        return Auth::user();
    } else {
        return 'Failed~';
    }
}
