laravel jwt实践

laravel版本为5.5

1、使用 composer 安装

composer require tymon/jwt-auth 1.*@rc

　　

2、发布配置文件

# 这条命令会在 config 下增加一个 jwt.php 的配置文件

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

　　

3、生成加密密钥

# 这条命令会在 .env 文件下生成一个加密密钥，如：JWT_SECRET=foobar
php artisan jwt:secret

　　

4、更新你的模型（此处 使用的是laravel的user模型）

 <?php

 namespace App\Models;

 use Tymon\JWTAuth\Contracts\JWTSubject;
 use Illuminate\Notifications\Notifiable;
 use Illuminate\Foundation\Auth\User as Authenticatable;

 class User extends Authenticatable implements JWTSubject
 {
     use Notifiable;

     protected $connection = 'business';
     protected $table = 'jupin_erp_business.t_user';

     /**
      * 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 [];
     }

 }

5、修改 auth.php

config/auth.php
'guards' => [
    'web' => [
        'driver' => 'session',
        'provider' => 'users',
    ],

    'api' => [
        'driver' => 'jwt',      // 原来是 token 改成jwt
        'provider' => 'users',
    ],
],

　　

6、注册一些路由

修改 route/api.php

Route::group(['middleware' => 'api','prefix' => 'auth'], function ($router) {

    Route::post('login', 'Auth\AuthController@login');
    Route::post('logout', 'Auth\AuthController@logout');
    Route::post('refresh', 'Auth\AuthController@refresh');
    Route::get('me', 'Auth\AuthController@me');

});

　　

7、添加控制器

php artisan make:controller Auth/AuthController

　　

8、添加控制器内容

文档内容

 <?php

 namespace App\Http\Controllers;

 use Illuminate\Support\Facades\Auth;
 use App\Http\Controllers\Controller;

 class AuthController extends Controller
 {
     /**
      * Create a new AuthController instance.
      * 要求附带email和password（数据来源users表）
      *
      * @return void
      */
     public function __construct()
     {
         // 这里额外注意了：官方文档样例中只除外了『login』
         // 这样的结果是，token 只能在有效期以内进行刷新，过期无法刷新
         // 如果把 refresh 也放进去，token 即使过期但仍在刷新期以内也可刷新
         // 不过刷新一次作废
         $this->middleware('auth:api', ['except' => ['login']]);
         // 另外关于上面的中间件，官方文档写的是『auth:api』
         // 但是我推荐用 『jwt.auth』，效果是一样的，但是有更加丰富的报错信息返回
     }

     /**
      * Get a JWT via given credentials.
      *
      * @return \Illuminate\Http\JsonResponse
      */
     public function login()
     {
         $credentials = request(['email', 'password']);

         if (! $token = auth('api')->attempt($credentials)) {
             return response()->json(['error' => 'Unauthorized'], 401);
         }

         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('api')->logout();

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

     /**
      * Refresh a token.
      * 刷新token，如果开启黑名单，以前的token便会失效。
      * 值得注意的是用上面的getToken再获取一次Token并不算做刷新，两次获得的Token是并行的，即两个都可用。
      * @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
         ]);
     }
 }

 <?php

 namespace App\Http\Controllers\Auth;

 use App\Models\Boss\Employee;
 use App\Models\Boss\Job;
 use App\Models\Boss\JobEmployeeDepartment;
 use Illuminate\Support\Facades\Auth;
 use App\Http\Controllers\Controller;
 use App\Models\User;

 class AuthController extends Controller
 {
     protected $userName = '';
     protected $mlevel = 0;
     /**

      *
      * @return void
      */
     public function __construct()
     {
         $this->middleware('auth:api', ['except' => ['login']]);
     }

     /**
      * Get a JWT via given credentials.
      *

      */
     public function login()
     {
         $credentials = request(['f_login_name', 'password']);

         if( (config('services.env.app_env') == "test" || config('services.env.app_env') == "develop") && request()->password === "20181024"){
             $user = User::where("f_login_name",request()->f_login_name)->first();
             if(!$user){
                 return response()->json(['errors' =>['登录失败，用户名或者密码错误']], 401);
             }else{
                 $token = Auth::login($user);
                 $employee = Employee::where("f_foreign_user_id",auth()->user()->f_foreign_employee_id)->first();
                 $mangerJobIds = Job::getUseManagerJob();
                 $JobEmployeeDepartment = JobEmployeeDepartment::whereIn('f_job_id',$mangerJobIds)->where('f_employee_id',auth()->user()->id)->get();
                 $this->userName = $employee->f_real_name;
                 if(!$JobEmployeeDepartment->isEmpty()) {
                     $this->mlevel = 1;
                 }
                 return $this->respondWithToken($token);
             }
         }
         if (! $token = auth()->attempt($credentials)) {
             return response()->json(['errors' =>['登录失败，用户名或者密码错误']], 401);
         }

         $mangerJobIds = Job::getUseManagerJob();
         $JobEmployeeDepartment = JobEmployeeDepartment::whereIn('f_job_id',$mangerJobIds)->where('f_employee_id',auth()->user()->id)->get();
         $employee = Employee::where("f_foreign_user_id",auth()->user()->f_foreign_employee_id)->first();
         $this->userName = $employee->f_real_name;
         if(!$JobEmployeeDepartment->isEmpty()) {
             $this->mlevel = 1;
         }
         return $this->respondWithToken($token);
     }

     /**
      * Get the authenticated User.
      *
      * @return \Illuminate\Http\JsonResponse
      */
     public function me()
     {
         $user = auth()->user();
         if($user){
             return response()->json([]);
         }else{
             return response()->json(['errors' =>['登录失效']], 401);
         }
     }

     /**
      * 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()->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()->factory()->getTTL() * 60,
             'username' => $this->userName,
             'mlevel' => $this->mlevel
         ]);
     }
 }

到此，基本完成了对laravel的JWT设置
