Laravel 身份验证登录不起作用

Laravel auth login not working

提问by zach

I am new to laravel, I'm working on a Laravel authentication system, and while registration works, but login doesn't do anything.

我是 Laravel 的新手，我正在研究 Laravel 身份验证系统，虽然注册有效，但登录没有任何作用。

UserController.php

用户控制器.php

class UserController extends Controller
{

    public function postSignUp(Request $request)
    {


        $email = $request['email'];
        $first_name = $request['first_name'];
        $password = bcrypt($request['password']);

        $user = new User;

        $user->email = $request->email;
        $user->first_name = $request->first_name;
        $user->password = bcrypt($request->password);

        $user->save();

        Auth::login($user);

        return redirect()->route('hotelier.index')->with('alert-success','Data has been saved successfully');


    }


    public function postSignIn(Request $request)
    {

        if(Auth::attempt(['email' => $request['email'], 'password' => $request['password']])){

            return redirect()->route('hotelier.index');

        }

         return redirect()->back();

    }

}

Route(web.php)

路线（web.php）

    Route::group(['middleware' => ['web']], function (){

        Route::get('/', function () {
            return view('welcome');
        });

        Route::resource('hotelier','HotelierController');

            Route::post('/signup', [

            'uses'=> 'UserController@postSignUp',
            'as' =>'signup'

        ]);


        Route::post('/signin', [

            'uses'=> 'UserController@postSignIn',
            'as' =>'signin'

        ]);


    } );

   Auth::routes();

   Route::get('/home', 'HomeController@index')->name('home');

Please let me know how i can login

请告诉我如何登录

Thanks

谢谢

You should just you the artisan command php artisan make:auth. This will create a few things. It will create an auth folder in both your Controllers folder and view folder. It will also add to your web.php route file assuming you are using laravel 5.4. In your controller/auth directory you will find your LoginController and RegisterController. it should literally have everything you need to auth. You will need to make sure you have an email or username attribute on your User model. Also you will need to have a password attribute. From there you may want to do some customization depending on your application.

你应该只是你的工匠命令 php artisan make:auth。这将创建一些东西。它将在您的 Controllers 文件夹和 view 文件夹中创建一个 auth 文件夹。假设您使用的是 laravel 5.4，它还会添加到您的 web.php 路由文件中。在您的 controller/auth 目录中，您将找到您的 LoginController 和 RegisterController。从字面上看，它应该包含您需要进行身份验证的所有内容。您需要确保您的用户模型上有电子邮件或用户名属性。您还需要有一个密码属性。从那里您可能希望根据您的应用程序进行一些自定义。

here is an example LoginController:

这是一个登录控制器示例：

<?php

namespace App\Http\Controllers\Auth;

use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;

class LoginController extends Controller
{
    /*
    |--------------------------------------------------------------------------
    | Login Controller
    |--------------------------------------------------------------------------
    |
    | This controller handles authenticating users for the application and
    | redirecting them to your home screen. The controller uses a trait
    | to conveniently provide its functionality to your applications.
    |
    */

    use AuthenticatesUsers;

    /**
     * Where to redirect users after login.
     *
     * @var string
     */
    protected $redirectTo = '/customer';

    /**
     * Create a new controller instance.
     *
     */
    public function __construct()
    {
        $this->middleware('guest')->except('logout');

    }

    protected $username = 'email';

    public function loginNameOrEmail(Request $request)
    {
        $field = filter_var($request->input('email'), FILTER_VALIDATE_EMAIL) ? 'email_address' : 'username';

        $request->merge([$field => $request->input('email')]);

        $this->username = $field;

        return $this->login($request);

    }


    public function username()
    {
        return $this->username;
    }

}

May be its too late but might help others. Have you noticed protected $fillable = [...]inside your Usermodel that extends Illuminate\Foundation\Auth\User as Authenticatable? Make sure you setting all the properties for the User Model those have been defined in protected $fillable = [...]and then try to login using Auth::login($user);My User model looks like namespace App\Models;

可能为时已晚，但可能会帮助其他人。你有没有注意到protected $fillable = [...]你的User模型内部有延伸Illuminate\Foundation\Auth\User as Authenticatable？确保为用户模型设置了所有已定义的属性protected $fillable = [...]，然后尝试使用Auth::login($user);类似于命名空间 App\Models 的 My User 模型登录；

use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable {

    use Notifiable;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    // Make sure you set these properties for the model
    protected $fillable = ['name', 'username', 'email', 'password', 'contact',];
.

I know this is a late answer, but I solved this issue just now using Auth::login()instead of using auth()->login().

我知道这是一个迟到的答案，但我刚刚使用Auth::login()而不是使用auth()->login().

I think this should be the same but I don't know the main reason why it works for Auth::login()and not auth()->login().

我想这应该是相同的，但我不知道是最主要的原因，它的工作原理为Auth::login()，而不是auth()->login()。

Use this in your sign in controller

在您的登录控制器中使用它

 $email = $request->input('email');
        $password = $request->input('password');
        if (Auth::attempt(['email' => $email, 'password' => $password]))
