如何利用laravelPassport实现API认证

安装larave

laravel new passport_demo
cd passport_demo && composer install

将 .env 中数据库配置修改为自己的数据库配置

 DB_DATABASE=homestead
 DB_USERNAME=homestead
 DB_PASSWORD=secret

安装Passport

composer require laravel/passport
php artisan migrate
php artisan passport:install

执行时可能出现以下错误

Illuminate\Database\QueryException  : SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 767 bytes (SQL: alter table `users` add unique `users_email_unique`(`email`))

编辑

 namespace App\Providers;
 use Illuminate\Support\ServiceProvider;
 use Illuminate\Support\Facades\Schema;//新增
 class AppServiceProvider extends ServiceProvider{
     public function boot(){}
     public function register(){
         Schema::defaultStringLength(191);//新增
     }
 }

然后再执行这两条命令即可

php artisan migrate
php artisan passport:install

编辑将添加到

 namespace App;
 use Illuminate\Notifications\Notifiable;
 use Illuminate\Foundation\Auth\User as Authenticatable;
 use Laravel\Passport\HasApiTokens;//新增
 class User extends Authenticatable{
     use Notifiable;
     use HasApiTokens;//新增
     protected $fillable = ['name', 'email', 'password',];
     protected $hidden = ['password', 'remember_token',];
 }

在的方法中调用函数

 namespace App\Providers;
 use Illuminate\Support\Facades\Gate;
 use Illuminate\Foundation\Support\Providers\AuthServiceProvider as ServiceProvider;
 use Laravel\Passport\Passport;//新增
 class AuthServiceProvider extends ServiceProvider{
     protected $policies = ['App\Model' => 'App\Policies\ModelPolicy',];
     public function boot(){
         $this->registerPolicies();
         Passport::routes();//新增
     }
 }

将配置文件中授权看守器的的选项改为

//修改前
 'guards' => [
     'web' => [
         'driver' => 'session',
         'provider' => 'users',
     ],
     'api' => [
         'driver' => 'token',
         'provider' => 'users',
     ],
 ],

// 修改后
 'guards' => [
     'web' => [
         'driver' => 'session',
         'provider' => 'users',
     ],
     'api' => [
         'driver' => 'passport',
         'provider' => 'users',
     ],
 ],

创建文件，这里的代码来自另一个教程。

 namespace App\Http\Controllers;
 use Illuminate\Http\Request;
 use App\Http\Controllers\Controller;
 use App\User;
 use Illuminate\Support\Facades\Auth;
 use Validator;
 class UserController extends Controller {
     public $successStatus = 200;
     public function login() {
         if(Auth::attempt(['email' => request('email'), 'password' => request('password')])) {
             $user = Auth::user();
             $success['token'] =  $user->createToken('MyApp')->accessToken;
             return response()->json(['success' => $success], $this->successStatus);
         }
         else{
             return response()->json(['error'=>'Unauthorised'], 401);
         }
     }
     public function register(Request $request) {
         $validator = Validator::make($request->all(), [
             'name' => 'required',
             'email' => 'required|email',
             'password' => 'required',
             'c_password' => 'required|same:password',
         ]);
         if ($validator->fails()) {
             return response()->json(['error'=>$validator->errors()], 401);
         }
         $input = $request->all();
         $input['password'] = bcrypt($input['password']);
         $user = User::create($input);
         $success['token'] =  $user->createToken('MyApp')->accessToken;
         $success['name'] =  $user->name;
         return response()->json(['success'=>$success], $this->successStatus);
     }
     public function details() {
         $user = Auth::user();
         return response()->json(['success' => $user], $this->successStatus);
     }
 }

使用postman进行测试
注册接口，注册成功后返回token与用户名

登录接口
