401 Unauthorized 仅出现在 Laravel 8 的某些页面上

Question

在 Laravel 8 中创建了一个应用程序，并使用 PHP artisan 命令“ui:auth”创建了一个登录系统，效果很好。但是，当尝试在其他控制器中使用“auth()->check()”时，出现 401 未授权错误。在应用程序中登录时都会发生这种情况，就像在 Postman 中一样。

我的控制器有问题：

 <?php

namespace App\Http\Controllers\Api;

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use App\Models\Store;
use Illuminate\Support\Facades\Auth;

class StoreController extends Controller
{

    public function __construct()
    {
        $this->middleware('auth');
    }


    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        //
    }

    /**
     * Display the specified resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function show()
    {
        return auth()->user();
    }

    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request, $id)
    {
        //
    }

    /**
     * Remove the specified resource from storage.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function destroy($id)
    {
        //
    }
}

Answer 1

它应该适合你。试试这个：仔细输入正确的凭据。

return Auth::user();

Answer 2

Laravel 的默认身份验证系统是 session，您无法使用 postman 登录。为此，您必须使用护照或 sanctum reader。然后你必须去“config/auth.php”并设置以下值

'guards' => [
'web' => [
    'driver' => 'session',
    'provider' => 'users',
],

'api' => [
    'driver' => 'passport',
    'provider' => 'users',
],

],

你必须使用“api 守卫”

问题最终通过更新 /app/Http/Kernel.php 并添加以下代码得到解决：

\App\Http\Middleware\EncryptCookies::class,
\Illuminate\Session\Middleware\StartSession::class,

到protected $middlewareGroups

protected $middlewareGroups = [
        'web' => [
            \App\Http\Middleware\EncryptCookies::class,
            \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
            \Illuminate\Session\Middleware\StartSession::class,
            // \Illuminate\Session\Middleware\AuthenticateSession::class,
            \Illuminate\View\Middleware\ShareErrorsFromSession::class,
            \App\Http\Middleware\VerifyCsrfToken::class,
            \Illuminate\Routing\Middleware\SubstituteBindings::class,
        ],

        'api' => [
            \App\Http\Middleware\EncryptCookies::class,
            \Illuminate\Session\Middleware\StartSession::class,
            // \Laravel\Sanctum\Http\Middleware\EnsureFrontendRequestsAreStateful::class,
            'throttle:api',
            \Illuminate\Routing\Middleware\SubstituteBindings::class,
        ],
    ];
