I expect that this error is coming from my route configuration, which I changed to Route::resourceinstead, as mentioned in the quickstart guide, of the deprecated - since laravel 5.3 - Route::controllers:
我希望这个错误来自我的路由配置，Route::resource正如快速入门指南中提到的那样，我改为使用已弃用的路由配置- 从 laravel 5.3 开始 - Route::controllers：
Route::resource('datatables', 'DatatablesController', [
'anyData' => 'datatables.data',
'getIndex' => 'datatables',
]);
Any suggestions how to write the route properly?
任何建议如何正确编写路线？
PS.: I already used composer dumpautoload, composer install& composer updateand it does not change the error
PS.: 我已经用过composer dumpautoload, composer install&composer update它不会改变错误

My current Controller looks like the following:
我当前的控制器如下所示：
namespace App\Http\Controllers;
use App\Http\Requests;
use App\User;
use Yajra\Datatables\Datatables;
class DatatablesController extends Controller
{
/**
* Displays datatables front end view
*
* @return \Illuminate\View\View
*/
public function getIndex()
{
return view('datatables.index');
}
/**
* Process datatables ajax request.
*
* @return \Illuminate\Http\JsonResponse
*/
public function anyData()
{
return Datatables::of(User::query())->make(true);
}
}
My view:
我的看法：
@extends('layouts.master')
@section('content')
<table class="table table-bordered" id="users-table">
<thead>
<tr>
<th>Id</th>
<th>Name</th>
<th>Email</th>
<th>Created At</th>
<th>Updated At</th>
</tr>
</thead>
</table>
@stop
@push('scripts')
<script>
$(function() {
$('#users-table').DataTable({
processing: true,
serverSide: true,
ajax: '{!! route('datatables.data') !!}',
columns: [
{ data: 'id', name: 'id' },
{ data: 'name', name: 'name' },
{ data: 'email', name: 'email' },
{ data: 'created_at', name: 'created_at' },
{ data: 'updated_at', name: 'updated_at' }
]
});
});
</script>

In your routes.php, Laravel search a controller (in your case, DatatablesController) and a method to execute in this controller like DatatablesController@methodToExecute.
By default, Laravel try to execute the method index. Like @madalinivascuwrote, this controller needs to exists.
在你的 routes.php 中，Laravel 搜索一个控制器（在你的例子中，DatatablesController）和一个在这个控制器中执行的方法，比如DatatablesController@methodToExecute。
默认情况下，Laravel 尝试执行方法index。就像@madalinivascu写的那样，这个控制器需要存在。
