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

<?phpreturn [ ... '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：

<?phpnamespace 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 (empty($user) || !$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.phpRoute::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');});

测试一下:

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。

<?phpnamespace 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); }}

加入token refresh

加入中间件代码：

<?phpnamespace 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', []); } }}

注册：

<?phpnamespace 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, ];}

相应的控制器构造函数修改：

public function __construct(){ $this->middleware('token.refresh', ['except' => ['login','refresh']]);}

把token时间设置成1分钟，测试一下。

可以根据api返回，去调用刷新接口。

简单使用就是这样啦。
