这篇文章主要给大家介绍了关于Laravel配合jwt使用的相关资料，文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值，需要的朋友们下面随着小编来一起学习学习吧。

测试使用的是Laravel5.5版本。

安装

composer require tymon/jwt-auth=1.0.0-rc.5

配置

生成配置

php artisan vendor:publish --provider="Tymon\JWTAuth\Providers\LaravelServiceProvider"

php artisan jwt:secret

auth配置

<?php

return [

...

'defaults' => [

  'guard' => 'web',

  'passwords' => 'users',

],

'guards' => [

  'web' => [

   'driver' => 'session',

   'provider' => 'users',

  ],

  // 使用jwt

  'api' => [

   'driver' => 'jwt',

   'provider' => 'apiUser',

  ],

],

'providers' => [

  ...

  // 指定model

  'apiUser' => [

   'driver' => 'eloquent',

   'model' => App\ApiUser::class,

  ],

],

];

编码

控制器：

<?php

namespace App\Http\Controllers\Api;

use App\ApiUser;

use App\Http\Controllers\Controller;

use Illuminate\Http\Request;

use Tymon\JWTAuth\Facades\JWTAuth;

class AuthController extends Controller

{

/**

  * 中间件去除login和refresh

  *

  * @return void

  */

public function __construct()

{

  $this->middleware('auth:api', ['except' => ['login','refresh']]);

}

/**

  * Get a JWT via given credentials.

  *

  * @return \Illuminate\Http\JsonResponse

  */

public function login(Request $request)

{

  $credentials = $request->only('phone', 'password');

  if (count($credentials) < 2) {

   return response()->json(['error' => 'Unauthorized'], 401);

  }

  $user = ApiUser::where('phone', $credentials['phone'])

   ->where('password', md5($credentials['password']))

   ->first();

  if (emptyempty($user) || !$token = JWTAuth::fromUser($user)) {

   return response()->json(['error' => 'Unauthorized'], 401);

  }

  // dd($token);

  return $this->respondWithToken($token);

}

/**

  * Get the authenticated User.

  *

  * @return \Illuminate\Http\JsonResponse

  */

public function me()

{

  return response()->json(auth('api')->user());

}

/**

  * Log the user out (Invalidate the token).

  *

  * @return \Illuminate\Http\JsonResponse

  */

public function logout()

{

  auth()->logout();

  return response()->json(['message' => 'Successfully logged out']);

}

/**

  * Refresh a token.

  *

  * @return \Illuminate\Http\JsonResponse

  */

public function refresh()

{

  return $this->respondWithToken(auth('api')->refresh());

}

/**

  * Get the token array structure.

  *

  * @param string $token

  *

  * @return \Illuminate\Http\JsonResponse

  */

protected function respondWithToken($token)

{

  return response()->json([

   'access_token' => $token,

   'token_type' => 'bearer',

   'expires_in' => auth('api')->factory()->getTTL() * 60

  ]);

}

}

路由：

此处注意，我为了方便测试，使用了get方法，生产环境不建议使用get。

// routes/api.php

Route::middleware('api')->prefix('auth')->namespace('Api')->group(function () {

Route::get('login', 'AuthController@login');

Route::post('logout', 'AuthController@logout');

Route::get('refresh', 'AuthController@refresh');

Route::get('me', 'AuthController@me');

});

unauthenticated处理

这里需要注意下，unauthenticated处理一下比较好，否则会默认跳转login登录页面。

<?php

namespace App\Exceptions;

use Exception;

use Illuminate\Foundation\Exceptions\Handler as ExceptionHandler;

use Illuminate\Auth\AuthenticationException;

class Handler extends ExceptionHandler

{

  ...

  protected function unauthenticated($request, AuthenticationException $exception)

  {

    return response()->json(['message' => 'Unauthenticated.'], 401);

     /*非api可以这么处理

    return $request->expectsJson()

          ? response()->json(['message' => 'Unauthenticated.'], 401)

          : redirect()->guest(route('login'));

          */

  }

}

加入token refresh

加入中间件代码：

<?php

namespace App\Http\Middleware;



use Closure;

use Tymon\JWTAuth\Facades\JWTAuth;

use Tymon\JWTAuth\Exceptions\JWTException;

use Illuminate\Auth\AuthenticationException;

use Tymon\JWTAuth\Exceptions\TokenExpiredException;

use Illuminate\Http\Exceptions\HttpResponseException;

use Tymon\JWTAuth\Http\Middleware\BaseMiddleware;

class RefreshToken extends BaseMiddleware

{

  /**

   * Handle an incoming request.

   *

   * @param \Illuminate\Http\Request $request

   * @param \Closure $next

   * @return mixed

   */

  public function handle($request, Closure $next)

  {

    try{

      //检查请求中是否带有token 如果没有token值则抛出异常

      $this->checkForToken($request);

      if ($request->user = JWTAuth::parseToken()->authenticate()) {

        return $next($request);

      }

      throw new AuthenticationException('Unauthorized', []);

    }catch (TokenExpiredException $exception){

      //返回特殊的code

      throw new HttpResponseException(response()->json([

        'message' => 'token expired'

      ]));

    } catch (\Exception $exception) {

      throw new AuthenticationException('Unauthorized', []);

    }

  }

}

<?php

namespace App\Http;

use Illuminate\Foundation\Http\Kernel as HttpKernel;

class Kernel extends HttpKernel

{

  ...

  protected $routeMiddleware = [

    'token.refresh' => \App\Http\Middleware\RefreshToken::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,

  ];

}
