Laravel合约给出500错误

Question

我为我的应用程序制作了一个Contract接口和一个Eloquent存储库，但是当我尝试使用它时出现500错误。

我觉得它与注册方式有关。 为此，请使用具有以下register方法的服务提供商：

/**
* Register service provider bindings
*/
public function registerBindings() {
    $this->app->bind(
        \App\Repositories\Backend\EventContract::class,
        \App\Repositories\Backend\EloquentEventRepository::class
    );
}

然后，在控制器中按以下方式使用合同：

EventController类扩展了控制器{

/**
 * @var EventContract
 */
protected $events;

/**
 * EventController constructor.
 * @param EventContract $events
 */
public function __construct(EventContract $events)
{
    $this->events = $events;
}

/**
 * Display a listing of the resource.
 *
 * @return \Illuminate\Http\Response
 */
public function index()
{

    return view('backend.events.index')
                ->withEvents($this->events->getEventsPaginated(25, 1));

当我用500错误加载页面时，Laravel日志或Nginx日志中没有任何条目（我将Homestead与Vagrant结合使用）。

任何想法？ 提前致谢

编辑：发现了一些日志！

可能是愚蠢的指针，但是没有危害检查：

1. 仔细检查相应文件中的名称空间，即EventContract和EloquentEventRepository类文件。

2. 如果未使用完整路径，请检查是否已在EventController中导入名称空间

3. 注册服务提供商后，您是否运行了composer dump-autoload -o

如果启用了调试，请尝试使用chrome devtools查看响应
