Laravel  Middleware(中间件) 设置登录信息(User Model)，然后在其它地方使用如 Controller(控制器)

### UserAdminAuthGuard 中间件
```php
<?php

namespace App\Http\Middleware;

use Auth;
use Closure;
use App\Models\User;
use Firebase\JWT\JWT;
use Firebase\JWT\Key;
use App\Libs\ResponseTool;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Redis;

class UserAdminAuthGuard
{
    /**
     * Handle an incoming request.
     *
     * @param \Illuminate\Http\Request $request
     * @param \Closure(\Illuminate\Http\Request): (\Illuminate\Http\Response|\Illuminate\Http\RedirectResponse)  $next
     * @return \Illuminate\Http\Response|\Illuminate\Http\RedirectResponse
     */
    public function handle(Request $request, Closure $next)
    {
		// 这里写你处理的相关逻辑
		// $token = 0;
		// 这里写你处理的相关逻辑

// 保存 用户模型
        Auth::login(User::where('token', $token)->firstOrFail());

return $next($request);
    }
}
```

### UserController - HTTP 控制器

```php
<?php

class UserContoller
{
	public function index(Request $request)
	{
		// 拿到用户模型信息
		dump(Auth::user());
	}
}
```

## 新建控制器名字为 ForExampleController.php

```php
<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class ForExampleController extends Controller
{
    public function index(Request $request)
    {
        if ('nowtime.cc' !== $request->get('domain')) {
            return response([
                'code' => 400,
                'msg' => '错误的参数',
            ]);
        }

return response([
            'code' => 200,
            'msg' => '验证通过',
        ]);
    }
}

```

## 新建测试文件名字为 ForExampleControllerTest.php

```php
<?php

namespace Tests\Feature;

use Tests\TestCase;
use Illuminate\Foundation\Testing\WithFaker;
use App\Http\Controllers\ForExampleController;
use Illuminate\Foundation\Testing\RefreshDatabase;

class ForExampleControllerTest extends TestCase
{
    public function testIndex()
    {
        $request = \Request::create('/', 'GET', [
            'domain' => 'nowtime.cc',
        ]);

$forExampleController = new ForExampleController();

$res = json_decode($forExampleController->index($request)->getContent(), true);

self::assertEquals(200, $res['code']);
    }
}

```

运行测试结果：
