Laravel 接口依赖注入

Question

我有一个接口依赖注入问题，错误消息看起来无法捕获 class，有什么理想吗？

错误信息：

FatalThrowableError in UserController.php line 27:
Class 'App\Http\Controllers\App' not found

我的文件夹路径：

UserController.php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Domain\Services\Social\SocialService;
use Domain\Services\Social\SocialInterface;
use Domain\Services\Social\Facebook;

class UserController extends Controller
{
  public function fb(Request $request)
  {
    App::bind(SocialInterface::class, Facebook::class);
    $target = App::make(SocialService::class);
    return $target ->getCallbackData($request);
  }
}

SocialService.php

namespace Domain\Services\Social;

class SocialService
{
    public function getCallbackData(SocialInterface $social,$request)
  {
      return $social->getCallbackData($request);
  }
}

Facebook.php

namespace Domain\Services\Social;

class Facebook implements SocialInterface
{

  public function getCallbackData($request)
  {
     //Somethig inside...
  }
}

Answer 1

  public function fb(Request $request)
  {
    \App::bind(SocialInterface::class, Facebook::class);
    $target = \App::make(SocialService::class);
    return $target ->getCallbackData($request);
  }

用反斜杠试试。
