我正在学习laravel，我决定在laravel中进行自定义身份验证。我可以注册我的用户，但当我尝试登录时，我收到此错误？
Type error: Argument 2 passed to Illuminate\Auth\SessionGuard::__construct() must implement interface Illuminate\Contracts\Auth\UserProvider, null given,
这些是我的资源 我的AdminUser模型
<?php
namespace App;
use Illuminate\Database\Eloquent\Model as Eloquent;
use Illuminate\Notifications\Notifiable;
use Illuminate\Auth\Authenticatable as AuthenticableTrait;
use Illuminate\Foundation\Auth\Access\Authorizable;
use Illuminate\Contracts\Auth\Authenticatable as AuthenticatableContract;
use Illuminate\Contracts\Auth\Access\Authorizable as AuthorizableContract;
class AdminUser extends Eloquent implements AuthenticatableContract,AuthorizableContract
{
public $table = "admin_users";
use Notifiable;
use AuthenticableTrait;
use Authorizable;
protected $fillable = [
'email', 'password',
];
/**
* The attributes that should be hidden for arrays.
*
* @var array
*/
protected $hidden = [
'password', 'remember_token',
];
}
我的AdminUserController
<?php
namespace App\Http\Controllers;
use App\AdminUser;
use App\Http\Controllers\Controller;
use Illuminate\Contracts\Auth\Guard;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use App\Http\Requests\LoginRequest;
use App\Http\Requests\RegisterRequest;
use Auth;
use Response;
class AdminUserController extends Controller {
use AuthenticatesUsers;
/**
* the model instance
* @var AdminUser
*/
protected $user;
/**
* The Guard implementation.
*
* @var Authenticator
*/
protected $admin;
/**
* Create a new authentication controller instance.
*
* @param Authenticator $admin
* @return void
*/
public function __construct(Guard $admin, AdminUser $user)
{
$user = AdminUser::first();
Auth::login($user);
$this->middleware('admin', ['except' => ['getLogout']]);
}
/**
* Show the application registration form.
*
* @return Response
*/
public function getRegister()
{
return view('admin/admin_users/register');
}
/**
* Handle a registration request for the application.
*
* @param RegisterRequest $request
* @return Response
*/
public function postRegister(RegisterRequest $request)
{
AdminUser::create([
'email' => $request->email,
'password' => bcrypt($request->password),
]);
return redirect('backend-admin/dashboard');
}
/**
* Show the application login form.
*
* @return Response
*/
public function getLogin()
{
return view('admin/admin_users/login');
}
/**
* Handle a login request to the application.
*
* @param LoginRequest $request
* @return Response
*/
public function postLogin(LoginRequest $request)
{
if (Auth::guard('admin')->attempt($request->only('email', 'password')))
{
return redirect()->intended('/backend-admin/dashboard');
}
return redirect('/backend-admin')->withErrors([
'email' => 'The credentials you entered did not match our records. Try again?',
]);
}
/**
* Log the user out of the application.
*
* @return Response
*/
public function getLogout()
{
Auth::guard('admin')->logout();
return redirect('/backend-admin');
}
protected function guard()
{
return Auth::guard();
}
}
我的VerifyAdmin中间件
<?php
namespace App\Http\Middleware;
use Closure;
use Illuminate\Contracts\Auth\Guard;
use Illuminate\Support\Facades\Auth;
class VerifyAdmin
{
/**
* The Guard implementation.
*
* @var Guard
*/
protected $admin;
/**
* Create a new filter instance.
*
* @param Guard $auth
* @return void
*/
public function __construct(Guard $auth)
{
// dd($auth);
$this->admin = $auth;
}
/**
* Handle an incoming request.
*
* @param \Illuminate\Http\Request $request
* @param \Closure $next
* @return mixed
*/
public function handle($request, Closure $next)
{
if ($this->admin->guest())
{
if ($request->ajax())
{
return response('Unauthorized.', 401);
}
else
{
return redirect()->guest('backend-admin');
}
}
return $next($request);
}
}
我还在auth.php中定义了警卫
<?php
return [
'defaults' => [
'guard' => 'web',
'passwords' => 'users',
],
'guards' => [
'web' => [
'driver' => 'session',
'provider' => 'users',
],
'api' => [
'driver' => 'token',
'provider' => 'users',
],
'admin' => [
'driver' => 'session',
'provider' => 'admins',
],
],
'providers' => [
'users' => [
'driver' => 'eloquent',
'model' => App\User::class,
],
'admin' => [
'driver' => 'eloquent',
'model' => App\AdminUser::class,
],
],
'passwords' => [
'users' => [
'provider' => 'users',
'table' => 'password_resets',
'expire' => 60,
],
],
];
还在kernel.php中定义了中间件
protected $routeMiddleware = [
'auth' => \Illuminate\Auth\Middleware\Authenticate::class,
'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
'bindings' => \Illuminate\Routing\Middleware\SubstituteBindings::class,
'can' => \Illuminate\Auth\Middleware\Authorize::class,
'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
'admin' => \App\Http\Middleware\VerifyAdmin::class,
如果我在任何地方错了或者我错过了什么，请随时纠正我。
答案 0 :(得分：1)
我发现了什么是我的程序错误，我在我的控制器中定义了防护功能，但忘记在功能中添加防护，我通过定义防护来修复它。
答案 1 :(得分：0)
我认为问题是这两行：
$user = AdminUser::first();
Auth::login($user);
运行它的重点是什么？首先，我看到你在这里有登录操作，看起来你在登录页面时自动登录管理员 - 它没有多大意义。
另外，这两行不会做任何我认为应该做的事情 - 因为当管理员登录时，你将他登录，所以假设你使用的话，没有必要在每个请求中登录他会话。
答案 2 :(得分：0)
您需要将管理员名称从admin更改为admins。
<?php
return [
'defaults' => [
'guard' => 'web',
'passwords' => 'users',
],
'guards' => [
'web' => [
'driver' => 'session',
'provider' => 'users',
],
'api' => [
'driver' => 'token',
'provider' => 'users',
],
'admin' => [
'driver' => 'session',
'provider' => 'admins',
],
],
'providers' => [
'users' => [
'driver' => 'eloquent',
'model' => App\User::class,
],
'admins' => [ // ***this is the change that should be made***
'driver' => 'eloquent',
'model' => App\AdminUser::class,
],
],
'passwords' => [
'users' => [
'provider' => 'users',
'table' => 'password_resets',
'expire' => 60,
],
],
];
