Question

我为我的应用程序创建了一个Contract接口和一个Eloquent Repository，但是当我尝试使用它时，我收到了500错误。

我觉得它与注册方式有关。要使用具有以下register方法的服务提供商执行此操作：

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

然后我在我的控制器中按如下方式使用合同：

class EventController扩展了Controller {

/**
 * @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));

当我加载500错误的页面时，Laravel日志或Nginx日志中没有条目（我使用带有Vagrant的Homestead）。

有什么想法吗？提前致谢

编辑：找到一些日志！

可能是愚蠢的指针，但没有伤害检查：

仔细检查各个文件中的命名空间，即EventContract 和EloquentEventRepository类文件。
检查是否已在EventController中导入名称空间if 不使用完整路径
在注册服务提供商你是否运行了composer dump-autoload -o

尝试使用chrome devtools查看调试时的响应

Laravel Contract提供500错误
