php jwt 实例,Laravel5 中使用 JWT 用户认证登陆实例

安装

将"tymon/jwt-auth": "1.0.0-beta.1" 添加到 composer.json 中，执行 composer update

或者

composer require tymon/jwt-auth 0.5.*

Providers

config/app.php 中在 providers 里添加

Tymon\JWTAuth\Providers\LaravelServiceProvider::class,

Class Aliases

config/app.php 中在 aliases 里添加

'JWTAuth' => Tymon\JWTAuth\Facades\JWTAuth::class

修改认证驱动

修改config/auth.php,将 api 的 driver 修改为 jwt。如下：

'guards' => [

'web' => [

'driver' => 'jwt',

'provider' => 'users',

],

'api' => [

'driver' => 'jwt',

'provider' => 'users',

],

]

修改模型文件 User.php

在最后加入这两个方法：

/**

* Get the identifier that will be stored in the subject claim of the JWT.

*

* @return mixed

*/

public function getJWTIdentifier()

{

return $this->getKey();

}

/**

* Return a key value array, containing any custom claims to be added to the JWT.

*

* @return array

*/

public function getJWTCustomClaims()

{

return [];

}

路由 web.php

Route::get('register', 'ApiController@Register');

Route::get('login', 'ApiController@Login');

Route::group(['middleware' => 'auth.jwt'], function () {

Route::get('userdetails', 'ApiController@UserDetails');

});

中间件 authJWT.php

记得要去kernel.php后将新建的中间件添加进去

namespace App\Http\Middleware;

use Closure;

class AuthJWT

{

public function handle($request, Closure $next)

{

$user = auth()->user();

if (is_null($user))

return response()-> json(['code'=>100]);

if($user['type'] == 1)

{

// 用户禁止登陆

return response()-> json(['code'=>101,'msg'=>'用户被禁止']);

}

return $next($request);

}

}

控制器Controller/ApiController.php

登陆生成token

public function Login(Request $request)

{

$input = request(['email', 'password']);

if (! $token = auth()->attempt($input)) {

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

}

return response()->json(['result' => $token]);

}

获取用户信息

public function UserDetails()

{

return response()->json(auth()->user()->toArray());

}
