这篇文章主要介绍了关于laravel dingo/api添加jwt-auth认证,有着一定的参考价值,现在分享给大家,有需要的朋友可以参考一下
前面我们学了laravel dingo/api创建简单的api,这样api是开放给所有人的,如何查看和限制api的调用呢?可以用jwt-auth来验证,JSON Web Token Authentication
1,首先安装jwt-auth插件,在命令行中用composer安装
composer require tymon/jwt-auth '0.5.*'
2,然后发布
php artisan vendor:publish --provider="Tymon\JWTAuth\Providers\JWTAuthServiceProvider"
在/config/生成了一个jwt.php文件
3,生成key
php artisan jwt:generate
如果命令无法运行,可以在/config/jwt.php文件中修改changeme为自己设置的密匙
'secret' => env('JWT_SECRET', 'changeme'),
4,修改/app/Api/Controllers/HelloController.php为
<?php namespace App\Api\Controllers; use Illuminate\Http\Request; use App\Http\Controllers\Controller; //添加jwt-auth认证 use JWTAuth; use Tymon\JWTAuth\Exceptions\JWTException; class HelloController extends Controller { public function index() { return '{content:Helloworld!}'; } //添加jwt-auth认证 public function authenticate(Request $request) { // grab credentials from the request $credentials = $request->only('email', 'password'); try { // attempt to verify the credentials and create a token for the user if (! $token = JWTAuth::attempt($credentials)) { return response()->json(['error' => 'invalid_credentials'], 401); } } catch (JWTException $e) { // something went wrong whilst attempting to encode the token return response()->json(['error' => 'could_not_create_token'], 500); } // all good so return the token return response()->json(compact('token')); } }
5,添加路由(/routes/web.php)
$api->post('auth', 'App\Api\Controllers\HelloController@authenticate');
6,测试路由:php artisan api:routes,如果出现如下提示表示正确
访问url:***.com/api/auth显示错误,因为没加token
重新修改hellocontrol和loutes
<?php namespace App\Api\Controllers; use Illuminate\Http\Request; use App\Http\Controllers\Controller; use JWTAuth; use Tymon\JWTAuth\Exceptions\JWTException; class HelloController extends Controller { /** * Create a new controller instance. * * @return void */ /** * Show the application dashboard. * * @return \Illuminate\Http\Response */ public function index() { return '{content:Helloworld!}'; } public function authenticate(Request $request) { // grab credentials from the request $credentials = $request->only('email', 'password'); try { // attempt to verify the credentials and create a token for the user if (! $token = JWTAuth::attempt($credentials)) { return response()->json(['error' => 'invalid_credentials'], 401); } } catch (JWTException $e) { // something went wrong whilst attempting to encode the token return response()->json(['error' => 'could_not_create_token'], 500); } // all good so return the token return response()->json(compact('token')); } //添加user public function user() { JWTAuth::parseToken(); $user = JWTAuth::parseToken()->authenticate(); return $user; } }
name('home'); $api = app('Dingo\Api\Routing\Router'); $api->version('v1', function ($api) { $api->get('helloworld', 'App\Api\Controllers\HelloController@index'); $api->post('auth', 'App\Api\Controllers\HelloController@authenticate'); $api->get('auth', 'App\Api\Controllers\HelloController@user'); });
用谷歌浏览器postman插件获取token,注意是post方法,步骤如下图所示
将获取的token复制,黏贴到第二步的用户验证token中,下图5中就是我们刚刚注册的用户
