尝试登录时，我的守卫总是在自定义中间件中返回 null

如何解决尝试登录时，我的守卫总是在自定义中间件中返回 null

我正在尝试进行多重身份验证，但我似乎无法使其正常工作。我使用的是自定义中间件而不是 RedirectIfAuthenticated 中间件，但 guard 总是在我的中间件中返回 null，但是当我使用 RedirectIfAuthenticated 中间件时，它可以工作。 这是我的代码

Auth.php

from elasticsearch import Elasticsearch,RequestsHttpConnection
from elasticsearch_dsl import Search

# use aws4auth to make auth
# host is without https://

es = Elasticsearch(hosts=[{'host': host,'port': 443}],http_auth=auth,use_ssl=True,verify_certs=True,connection_class=RequestsHttpConnection)

s = Search.from_dict({
        "query": {
            "regexp": {
                "roadmapParams.L.M.project_id.S": partial_match
            }
        },}).index('MYINDEX').using(es)

response = s.execute()

用户模型

   'defaults' => [
    'guard' => 'web','passwords' => 'users',],/*
|--------------------------------------------------------------------------
| Authentication Guards
|--------------------------------------------------------------------------
|
| Next,you may define every authentication guard for your application.
| Of course,a great default configuration has been defined for you
| here which uses session storage and the Eloquent user provider.
|
| All authentication drivers have a user provider. This defines how the
| users are actually retrieved out of your database or other storage
| mechanisms used by this application to persist your user's data.
|
| Supported: "session","token"
|
*/

'guards' => [
    'web' => [
        'driver' => 'session','provider' => 'users','api' => [
        'driver' => 'token','hash' => false,'admin' => [
        'driver' => 'session','provider' => 'admins','user' => [
        'driver' => 'session','provider' => 'users'
    ],/*

| User Providers
|--------------------------------------------------------------------------

| mechanisms used by this application to persist your user's data.
|
| If you have multiple user tables or models you may configure multiple

| be assigned to any extra authentication guards you have defined.
|
| Supported: "database","eloquent"

*/

'providers' => [
    'admins' => [
        'driver' => 'eloquent','model' => App\Admin::class,'users' => [
        'driver' => 'eloquent','model' => App\User::class,// 'users' => [
    //     'driver' => 'database',//     'table' => 'users',// ],

}

userLoginController

    public $table = 'users';
use Notifiable;

/**
 * The attributes that are mass assignable.
 *
 * @var array
 */

 protected $guard = 'user';

protected $fillable = [
    'name','email','password',];

/**
 * The attributes that should be hidden for arrays.
 *
 * @var array
 */
protected $hidden = [
    'password','remember_token',];

/**
 * The attributes that should be cast to native types.
 *
 * @var array
 */
protected $casts = [
    'email_verified_at' => 'datetime',];

public function verifyUser() {
    return $this->hasOne('App\VerifyUser');
}

}

这是我的中间件

    use AuthenticatesUsers;

public function __construct()
{
    $this->middleware('guest:user')->except('logout');
}

public function showLoginForm() {
    return view('user.login');
}

protected function guard() {
    return Auth::guard('user');
}

public function login(Request $request) {
    $this->validate($request,[
        'email' => 'required|email','password' => 'required|min:8'
    ]);

    if(Auth::guard('user')->attempt(['email' => $request->email,'password' => $request->password],$request->remember)) {
        // return $this->sendLoginResponse($request);
        // if(Auth::check()) {
            return redirect()->route('userdashboard');
        // }
    }

    return redirect()->back()->withInput($request->only('email','remember'));
}

protected function authenticated(Request $request,$user) {   
    echo $user->email_verified_at;
    die();
    // if($user->email_verified_at == null) {
    //     Auth::logout();
    //     return back()->with('warning','You need to confirm your email account. We have sent you an email verification code. Please check your email.');
    // }
}

public function logout() {
    session::flush();
    Auth::logout();
    return redirect()->route('userlogin');
}

protected function loggedOut(Request $request)
{
    return redirect('user/login');
}

解决方法

如果你想让你的中间件得到一个参数，你必须在分配中间件时用参数来定义它：

Route::get(...)->middleware('user:user');

第一个 user 是中间件的名称。 : 之后是将传递给中间件的 handle 方法的参数。所以这个中间件最终会以 $guard 为 user。
