关于passport client_credentials 模式 需要登录问题

请教一个问题。我想写一个http接口， 采用 laravel passport client_credentials模式，现在passport搭建好了。用postman测试也能取到token，但是我现在定义了一个接口。用postman测试 跳转到用户登录验证界面，不会进入我写接口内。我本意是不需要用户验证，因为我的接口提示给其他系统用的，不要用户验证。
在api.php中定义了Route::post('upload', 'UploadFileController@upload');
然后写了app/http/app/http/controllers中定义了一个控制器，代码如下：
namespace App\Http\Controllers;

class UploadFileController extends Controller {
//
public function upload() {
print_r($_POST);
print_r($_FILES);
file_put_contents('c:/ssss.log', 's');

}

}
kernel.php中我是这样定义的
protected $middlewareGroups = [
'web' => [
\App\Http\Middleware\EncryptCookies::class,
\Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
\Illuminate\Session\Middleware\StartSession::class,
// \Illuminate\Session\Middleware\AuthenticateSession::class,
\Illuminate\View\Middleware\ShareErrorsFromSession::class,
\App\Http\Middleware\VerifyCsrfToken::class,
\Illuminate\Routing\Middleware\SubstituteBindings::class,
],

    'api' => [
        'throttle:60,1',
        'bindings',
        'client',
    ],
];

/**
 * The application's route middleware.
 *
 * These middleware may be assigned to groups or used individually.
 *
 * @var array
 */
protected $routeMiddleware = [
    'auth' => \Illuminate\Auth\Middleware\Authenticate::class,
    'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
    'bindings' => \Illuminate\Routing\Middleware\SubstituteBindings::class,
    'cache.headers' => \Illuminate\Http\Middleware\SetCacheHeaders::class,
    'can' => \Illuminate\Auth\Middleware\Authorize::class,
    'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
    'signed' => \Illuminate\Routing\Middleware\ValidateSignature::class,
    'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
    'client' => \Laravel\Passport\Http\Middleware\CheckClientCredentials::class,
];

AuthServiceProvider.php 中 我是这样定义的
public function boot() {
$this->registerPolicies();
Passport::routes();
}
