说明:最近在写JWT相关逻辑,参考这篇文章配置JWT,具体怎么配置,这里就不说了,这篇文章主要针对token的验证,通过中间件来实现。

补充一下,我的项目是两个模块的,路由api那个我同事再用,我是后台所以新增一个admin路由文件,用户体系也不同,他是user表,我是user_admin表,所以第一步先配置我的模块的信息

第一步,配置自己的guards

在config/auth.php里面的guards数组新增admin键值:

'guards' => [
        'web' => [
            'driver' => 'session',
            'provider' => 'users',
        ],
        'api' => [
            'driver' => 'jwt',
            'provider' => 'apiusers',
        ],
        'admin' => [ //admin模块
            'driver' => 'jwt',
            'provider' => 'admin',
        ],
    ],

然后我下面找providers数组,新增admin模块:

'providers' => [
        'users' => [
            'driver' => 'eloquent',
            'model' => App\Models\User::class,
        ],

        'apiusers' => [
            'driver' => 'eloquent',
            'model' => App\Models\User::class,
        ],

        'admin' => [ //admin模块
            'driver' => 'eloquent',
            'model' => App\Models\UserAdmin::class, //admin的用户模型
        ],
    ],

第二步,生产中间件

通过命令:

php artisan make:middleware AuthAdminJwt 

AuthAdminJwt类里面内容如下:

<?php
namespace App\Http\Middleware;

use App\Models\UserAdmin;
use Closure;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Config;
use Tymon\JWTAuth\Facades\JWTAuth;
use Tymon\JWTAuth\Exceptions\JWTException;
use Tymon\JWTAuth\Exceptions\TokenExpiredException;
use Tymon\JWTAuth\Exceptions\TokenInvalidException;

class AuthAdminJwt
{
    /**
     * @param Request $request
     * @param Closure $next
     * @return \Illuminate\Http\JsonResponse|mixed
     */
    public function handle(Request $request, Closure $next)
    {
        //配置JWTAuth::parseToken()->authenticate()读取user_admin表,默认读取user表
        Config::set('auth.providers.users.model', UserAdmin::class);
        try {
            if (!$user = JWTAuth::parseToken()->authenticate()) { //获取到用户数据,并赋值给$user
                return response()->json([
                    'code' => 1,
                    'message' => '用户不存在'
                ], 404);
            }
            return $next($request);
        } catch (TokenExpiredException $e) {
            return response()->json([
                'code' => 1003,
                'message' => 'token已过期',
            ]);
        } catch (TokenInvalidException $e) {
            return response()->json([
                'code' => 1002,
                'message' => 'token无效',
            ]);
        } catch (JWTException $e) {
            return response()->json([
                'code' => 1001,
                'message' => '缺少token参数',
            ]);
        }
    }
}

第三步:配置路由

第一种:配置路由中间件属性

(1):通过路由规则配:


在Http\Kernel.php里面:

protected $routeMiddleware = [
        'jwt.admin.auth' => \App\Http\Middleware\AuthAdminJwt::class,
    ];

然后配置路由规则:

Route::get("/user/detail", [UserController::class, "detail"])->middleware('jwt.admin.auth');

运行这个路由,如果没有给token,就会报错。成功。

(2)还有一种是通过控制器配置中间件:


在Http\Kernel.php里面,这个和上面一样:

protected $routeMiddleware = [
        'jwt.admin.auth' => \App\Http\Middleware\AuthAdminJwt::class,
    ];

接着在控制器里面的构造方法里面:

<?php
/**
 * Created by PhpStorm.
 * User: xyf
 * Date: 2022/5/6
 * Time: 13:34
 */

namespace App\Http\Admin\Account;

use App\Http\Admin\Controller;
use App\Http\Requests\AdminLoginRequest;
use App\Models\UserAdmin;

class LoginController extends Controller
{
    public function __construct()
    {
        //除了login方法,其他需要验证token
        $this->middleware('jwt.admin.auth', ['except' => ['login']]);
    }

    /**
     * 登录
     *
     * @param AdminLoginRequest $request
     * @return \Illuminate\Http\JsonResponse
     */
    public function login(AdminLoginRequest $request)
    {
        $credentials = request(['mobile', 'password']);
        if (!$token = auth("admin")->attempt($credentials)) {
            return $this->fail("登录失败");
        }

        return $this->success([
            'access_token' => $token,
            'token_type' => 'Bearer',
            'expires_in' => auth('admin')->factory()->getTTL()
        ]);
    }

    /**
     * 退出登录
     *
     * @return \Illuminate\Http\JsonResponse
     */
    public function logout()
    {
        auth("admin")->logout();
        return $this->success();
    }

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

第二种:配置路由中间件组属性

在Http\Kernel.php里面:

 protected $middlewareGroups = [
        'web' => [
           //.......
        ],

        'api' => [
          //......
        ],
        'admin'=>[
            \App\Http\Middleware\Auth\AuthAdminJwt::class,
        ]
    ];

或则另一种写法:

 protected $middlewareGroups = [
        'web' => [
           //.......
        ],

        'api' => [
          //......
        ],
        'admin'=>[
              /**
              这种写法前提是在protected $routeMiddleware = [
             'jwt.admin.auth' => \App\Http\Middleware\AuthAdminJwt::class,]配置了
             **/
          "jwt.admin.auth"
    ];
        ]
    ];

然后配置路由规则:

Route::group(['middleware' => 'admin'],function(){
    Route::post("/account/test", [LoginController::class, "test"]);
    Route::post("/account/logout", [LoginController::class, "logout"]);
});

或则另一种写法:

Route::middleware(['admin'])->group(function (){
  Route::post("/account/test", [LoginController::class, "test"]);
  Route::post("/account/logout", [LoginController::class, "logout"]);
});

这样你运行上面的路由就会验证token
