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 (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' => $token,
'token_type' => 'bearer',
'expires_in' => auth('api')->factory()->getTTL() * 60
]);
}
}
路由：
此处注意，我为了方便测试，使用了get方法，生产环境不建议使用get。
// routes/api.php
Route::middleware('api')->prefix('auth')->namespace('Api')->group(function () {
Route::get('login', 'AuthController@login');
Route::post('logout', 'AuthController@logout');
Route::get('refresh', 'AuthController@refresh');
Route::get('me', 'AuthController@me');
});
测试一下:
unauthenticated处理
这里需要注意下，unauthenticated处理一下比较好，否则会默认跳转login登录页面。
<?php
namespace App\Exceptions;
use Exception;
use Illuminate\Foundation\Exceptions\Handler as ExceptionHandler;
use Illuminate\Auth\AuthenticationException;
class Handler extends ExceptionHandler
{
...
protected function unauthenticated($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', []);
}
}
}
注册：
<?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,
];
}
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。
