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=homesteadDB_USERNAME=homesteadDB_PASSWORD=secret

安装Passport

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

执行php artisan migrate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app/Providers/AppServiceProvider.php

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

然后再执行这两条命令即可

php artisan migrate
php artisan passport:install

编辑App\User将Laravel\Passport\HasApiTokens添加到App\User

 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app/Providers/AuthServiceProvider.php的 boot方法中调用Passport::routes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config/auth.php中授权看守器guards的api的driver选项改为passport

//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app/Http/Controllers/UserController.php，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
