Laravel API Wrapper-无法找到自动加载的包

Question

我目前正在尝试为Laravel构建我的第一个API包装器，但在自动加载实际的PHP-Lirbary时遇到了一些问题。

当我尝试在视图中访问窗口小部件时收到以下错误。

错误：

ErrorException (E_ERROR)
Class 'Uploadcare\Api' not found

查看

{!! app()->uploadcare->widget->getInputTag('file_input') !!}

我的包ServiceProvider看起来像这样。

UploadcareServiceProvider

use Illuminate\Support\ServiceProvider;
use Uploadcare\Api as Uploadcare;


class UploadcareServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap the application services.
     *
     * @return void
     */
    public function boot()
    {
        $this->publishes([
            __DIR__.'/config/uploadcare.php' => config_path('uploadcare.php'),
        ]);
    }



    /**
     * Register the application services.
     *
     * @return void
     */
    public function register()
    {

        $this->app->singleton('uploadcare', function($app) {

            $publicKey = config('uploadcare.public_key');
            $privateKey = config('uploadcare.private_key');

            return new Uploadcare($publicKey, $privateKey);

        });
    }


    /**
     * Get the services provided by the provider.
     *
     * @return array
     */
    public function provides()
    {
        return [
            Uploadcare::class,
        ];
    }
}

在我的包中，composer.json文件需要包。

包composer.json

"require": {
        "uploadcare/uploadcare-php": "^2.1"
    }

在软件包的Vendor文件夹中，我能够找到 Uploadcae \ Api 类，所以我不确定为什么我收到此错误。

包composer.json
