Laravel Passport

使用Laravel Passport 实现api用户认证

参考：

使用Laravel Passport

Passport配置

composer require laravel/passport

//表迁移，生成oauth相关的表
php artisan migrate

php artisan passport:install

app/User.php

<?php
...
use Laravel\Passport\HasApiTokens;
class User extends Authenticatable 
{
    use Notifiable,HasApiTokens;
}

引入 HasApiTokens

app/Providers/AuthServiceProvider.php

<?php
<?php

namespace App\Providers;

use Illuminate\Support\Facades\Gate;
use Illuminate\Foundation\Support\Providers\AuthServiceProvider as ServiceProvider;
use Laravel\Passport\Passport;

class AuthServiceProvider extends ServiceProvider
{
    /**
     * The policy mappings for the application.
     *
     * @var array
     */
    protected $policies = [
         'App\Model' => 'App\Policies\ModelPolicy',
    ];

    /**
     * Register any authentication / authorization services.
     *
     * @return void
     */
    public function boot()
    {
        $this->registerPolicies();

        //引入Ppassport routes,
        //注册必要的路由去颁发访问令牌，撤销访问令牌，客户端和个人令牌
        Passport::routes();

        
    }
}

config/auth.php

'api' => [
    //driver 改为passport
    'driver' => 'passport',
    'provider' => 'users',
    'hash' => false,
],

添加api 路由

routes/api.php

<?php
Route::group([
    'prefix' => 'auth'
], function () {
    Route::post('login', 'AuthController@login');
    Route::post('signup', 'AuthController@signup');

    Route::group([
      'middleware' => 'auth:api'
    ], function() {
        Route::get('logout', 'AuthController@logout');
        Route::get('user', 'AuthController@user');
    });
});

创建控制器

app/Http/Controllers/AuthController.php

<?php

namespace App\Http\Controllers;

use App\User;
use Carbon\Carbon;
use Illuminate\Http\Request;
use Auth;
use Illuminate\Support\Facades\Log;
class AuthController extends Controller
{
    public function signup(Request $request)
    {
        $request->validate([
            'name' => 'required|string',
            'email' => 'required|string|email',
            'password' => 'required|string',
        ]);

        $user = new User([
            'name'=>$request->name,
            'email'=>$request->email,
            'password'=>bcrypt($request->password)
        ]);

        $user->save();

        return response()->json([
            'message'=>'create user success'
        ],201);

    }

    public function login(Request $request)
    {
        $request->validate([
            'email' => 'required|string|email',
            'password' => 'required|string',
            'remember' => 'boolean'
        ]);

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

        if (!Auth::attempt($credentials)) {
            return response()->json([
                'message' => 'unauthorized'
            ],401);
        }

        $user = $request->user();

        $tokenResult = $user->createToken('Personal Access Token');
        Log::info($tokenResult);
        $token = $tokenResult->token;

        if ($request->remember_me) {
            $token->expires_at = Carbon::now()->addWeeks(1);
        }

        $token->save();
        return response()->json([
            'access_token' => $tokenResult->accessToken,
            'token_type' => 'Bearer',
            'expires_at' => Carbon::parse(
                $tokenResult->token->expires_at
            )->toDateTimeString()
        ]);
    }

    public function logout(Request $request)
    {
        $request->user()->token()->revoke();

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

    public function user(Request $request)
    {
        return response()->json($request->user());
    }
}

public function login(Request $request)中的

$tokenResult = $user->createToken('Personal Access Token');

$tokenResult的数据结构

{"accessToken":"eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiIsImp0aSI6IjcxNDQyZmVjMzBhNGI3ZWVjMmY2YTMyOTQwYjkyNjkzNzRjNTE1MTNjOWFhMzVlYTY1ODRl......",
"token":{"id":"71442fec30a4b7eec2f6a32940b9269374c51513c9aa35ea6584e051e6e21075f2255c765028a44a",
"user_id":52,"client_id":1,
"name":"Personal Access Token","scopes":[],"revoked":false,"created_at":"2019-06-01 02:30:45","updated_at":"2019-06-01 02:30:45",
"expires_at":"2020-06-01 02:30:45"}
}

public function logout(Request $request)调用
$request->user()->token()->revoke();
注销用户
