看到Laravel-China 社区常有人问 Laravel Passport 用于密码验证方式来获取 Token 的问题，刚好我最近一个 API 项目使用 Laravel Dingo Api+Passport，也是使用 Oauth2 的'grant_type' => 'password'密码授权来做 Auth 验证，对于如何做登录登出，以及多账号系统的认证等常用场景做一下简单的使用小总结。

基本配置

基本安装配置主要参照官方文档,具体不详细说，列出关键代码段

config/auth.php

'guards' => [
        'api' => [
            'driver' => 'passport',
            'provider' => 'users',
        ],
    ],

 'providers' => [
        'users' => [
            'driver' => 'eloquent',
            'model' => AppModelsUser::class
        ],
    ],

Providers/AuthServiceProvider.php

    public function boot()
    {
        $this->registerPolicies();

        //默认令牌发放的有效期是永久
        //Passport::tokensExpireIn(Carbon::now()->addDays(2));
        //Passport::refreshTokensExpireIn(Carbon::now()->addDays(4));
        Passport::routes(function (RouteRegistrar $router) {
            //对于密码授权的方式只要这几个路由就可以了
            config(['auth.guards.api.provider' => 'users']);
            $router->forAccessTokens();
        });
    }

Middleware/AuthenticateApi.php 自定义中间件返回

<?php

namespace AppHttpMiddleware;

use Closure;
use IlluminateAuthMiddlewareAuthenticate;
use SymfonyComponentHttpKernelExceptionUnauthorizedHttpException;

class AuthenticateApi extends Authenticate
{
    protected function authenticate(array $guards)
    {

        if ($this->auth->guard('api')->check()) {
            return $this->auth->shouldUse('api');
        }

        throw new UnauthorizedHttpException('', 'Unauthenticated');
    }
}

App/Http/Kernel.php

    /**
     * The application's route middleware.
     *
     * These middleware may be assigned to groups or used individually.
     *
     * @var array
     */
    protected $routeMiddleware = [
        'api-auth' => AuthenticateApi::class,
        ......
    ];
}

账号验证字段不止邮箱

对于账号验证不止是数据表中的 emial 字段，还可能是用户名或者手机号字段只需要在 User 模型中添加findForPassport方法，示例代码如下:

AppModelsUsers

class User extends Authenticatable implements Transformable
{
    use TransformableTrait, HasApiTokens, SoftDeletes;
    public function findForPassport($login)
    {
        return $this->orWhere('email', $login)->orWhere('phone', $login)->first();
    }
}

客户端获取 access_token 请求只传用户名和密码

对于密码授权的方式需要提交的参数如下:

$response = $http->post('http://your-app.com/oauth/token', [
    'form_params' => [
        'grant_type' => 'password',
        'client_id' => 'client-id',
        'client_secret' => 'client-secret',
        'username' => 'taylor@laravel.com',
        'password' => 'my-password',
        'scope' => '',
    ],
]);

但是客户端请求的时候不想把grant_type,client_id,client_secret,scope放到请求参数中或者暴露给客户端，只像 JWT 一样只发送username和password 怎么办？很简单我们只要将不需要请求的放到配置文件中，然后客户端请求用户名密码以后我们再向oauth/token发送请求带上相关的配置就可以了。

.env.php

OAUTH_GRANT_TYPE=password
OAUTH_CLIENT_ID=1
OAUTH_CLIENT_SECRET=EvE4UPGc25TjXwv9Lmk432lpp7Uzb8G4fNJsyJ83
OAUTH_SCOPE=*

config/passport.php 当然该配置你可以配置多个client

return [
    'grant_type' => env('OAUTH_GRANT_TYPE'),
    'client_id' => env('OAUTH_CLIENT_ID'),
    'client_secret' => env('OAUTH_CLIENT_SECRET'),
    'scope' => env('OAUTH_SCOPE', '*'),
];

LoginController.php的示例代码如下，因为用了Dingo Api配置了api前缀，所以请求/api/oauth/token

 	/**
     * 获取登录TOKEN
     * @param LoginRequest $request
     * @return IlluminateHttpJsonResponse
     */
    public function token(LoginRequest $request)
    {
        $username = $request->get('username');
        $user = User::orWhere('email', $username)->orWhere('phone', $username)->first();

        if ($user && ($user->status == 0)) {
            throw  new UnauthorizedHttpException('', '账号已被禁用');
        }

        $client = new Client();
        try {
            $request = $client->request('POST', request()->root() . '/api/oauth/token', [
                'form_params' => config('passport') + $request->only(array_keys($request->rules()))
            ]);

        } catch (RequestException $e) {
            throw  new UnauthorizedHttpException('', '账号验证失败');
        }

        if ($request->getStatusCode() == 401) {
            throw  new UnauthorizedHttpException('', '账号验证失败');
        }
        return response()->json($request->getBody()->getContents());
    }

退出登录并清除 Token

对于客户端退出后并清除记录在oauth_access_tokens表中的记录，示例代码如下:

  /**
     * 退出登录
     */
    public function logout()
    {
        if (Auth::guard('api')->check()) {
            Auth::guard('api')->user()->token()->delete();
        }

        return response()->json(['message' => '登出成功', 'status_code' => 200, 'data' => null]);
    }

根据用户 ID 认证用户

app('auth')->guard('api')->setUser(User::find($userId));

多用户表（多 Auth）认证

比如针对客户表和管理员表分别做 Auth 认证的情况，也列出关键代码段:

 'guards' => [
        'api' => [
            'driver' => 'passport',
            'provider' => 'users',
        ],

        'admin_api' => [
            'driver' => 'passport',
            'provider' => 'admin_users',
        ],
    ],

    'providers' => [
        'users' => [
            'driver' => 'eloquent',
            'model' => AppModelsUser::class
        ],

        'admin_users' => [
            'driver' => 'eloquent',
            'model' => AppModelsAdminUser::class
        ],
    ],

新建一个PasspordAdminServiceProvider来实现我们自己的PasswordGrant,别忘了添加到config/app.php的providers配置段中

AppProviders/PasspordAdminServiceProvider

<?php

namespace AppProviders;

use AppFoundationRepositoryAdminUserPassportRepository;
use LeagueOAuth2ServerGrantPasswordGrant;
use LaravelPassportPassportServiceProvider as BasePassportServiceProvider;
use LaravelPassportPassport;

class PasspordAdminServiceProvider extends BasePassportServiceProvider
{
    /**
     * Create and configure a Password grant instance.
     *
     * @return PasswordGrant
     */
    protected function makePasswordGrant()
    {
        $grant = new PasswordGrant(
            //主要是这里，我们调用我们自己UserRepository
            $this->app->make(AdminUserPassportRepository::class),
            $this->app->make(LaravelPassportBridgeRefreshTokenRepository::class)
        );

        $grant->setRefreshTokenTTL(Passport::refreshTokensExpireIn());

        return $grant;
    }

}

新建AdminUserPassportRepository，Password 的验证主要通过getUserEntityByUserCredentials,它读取配置的guards对应的provider来做认证，我们重写该方法，通过传递一个参数来告诉它我们要用哪个guard来做客户端认证

<?php

namespace AppFoundationRepository;

use App;
use IlluminateHttpRequest;
use LeagueOAuth2ServerEntitiesClientEntityInterface;
use LaravelPassportBridgeUserRepository;
use LaravelPassportBridgeUser;
use RuntimeException;

class AdminUserPassportRepository extends UserRepository
{

    public function getUserEntityByUserCredentials($username, $password, $grantType, ClientEntityInterface $clientEntity)
    {
        $guard = App::make(Request::class)->get('guard') ?: 'api';//其实关键的就在这里，就是通过传递一个guard参数来告诉它我们是使用api还是admin_api provider来做认证
        $provider = config("auth.guards.{$guard}.provider");
        if (is_null($model = config("auth.providers.{$provider}.model"))) {
            throw new RuntimeException('Unable to determine user model from configuration.');
        }

        if (method_exists($model, 'findForPassport')) {
            $user = (new $model)->findForPassport($username);
        } else {
            $user = (new $model)->where('email', $username)->first();
        }


        if (!$user) {
            return;
        } elseif (method_exists($user, 'validateForPassportPasswordGrant')) {
            if (!$user->validateForPassportPasswordGrant($password)) {
                return;
            }
        } elseif (!$this->hasher->check($password, $user->password)) {
            return;
        }

        return new User($user->getAuthIdentifier());
    }
}

登录和单用户系统一样，只是在请求oauth/token的时候带上guard参数，示例代码如下:

Admin/Controllers/Auth/LoginController.php

<?php

namespace AdminControllersAuth;

use AdminRequestsAuthLoginRequest;
use AppHttpControllersController;
use AppModelsUser;
use GuzzleHttpClient;
use GuzzleHttpExceptionRequestException;
use IlluminateFoundationAuthAuthenticatesUsers;
use IlluminateHttpRequest;
use SymfonyComponentHttpKernelExceptionUnauthorizedHttpException;

class LoginController extends Controller
{
    /*
    |--------------------------------------------------------------------------
    | Login Controller
    |--------------------------------------------------------------------------
    |
    | This controller handles authenticating users for the application and
    | redirecting them to your home screen. The controller uses a trait
    | to conveniently provide its functionality to your applications.
    |
    */

    use AuthenticatesUsers;

    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('guest')->except('logout');
    }

    /**
     * 获取登录TOKEN
     * @param LoginRequest $request
     * @return IlluminateHttpJsonResponse
     */
    public function token(LoginRequest $request)
    {
        $username = $request->get('username');
        $user = User::orWhere('email', $username)->orWhere('phone', $username)->first();

        if ($user && ($user->status == 0)) {
            throw  new UnauthorizedHttpException('', '账号已被禁用');
        }

        $client = new Client();
        try {
            $request = $client->request('POST', request()->root() . '/api/oauth/token', [
                'form_params' => config('passport') + $request->only(array_keys($request->rules())) + ['guard' => 'admin_api']
            ]);
        } catch (RequestException $e) {
            throw  new UnauthorizedHttpException('', '账号验证失败');
        }

        if ($request->getStatusCode() == 401) {
            throw  new UnauthorizedHttpException('', '账号验证失败');
        }
        return response()->json($request->getBody()->getContents());
    }

    /**
     * 退出登录
     */
    public function logout()
    {
        if (Auth::guard('admin_api')->check()) {
            Auth::guard('admin_api')->user()->token()->delete();
        }

        return response()->json(['message' => '登出成功', 'status_code' => 200, 'data' => null]);
    }
}
