【问题描述】：

我正在运行php 7.0.25 和Laravel Framework 5.5.25。

我想使用laravel datatables package 并遵循quickstart guide 并拥有完全相同的controller 和view。

但是，在运行我的应用程序时，我收到以下错误：

BadMethodCallException thrown with message "Method [index] does not exist on [App\Http\Controllers\DatatablesController]."

我希望这个错误来自我的路由配置，我改为 Route::resource，如 quickstart guide 中所述，已弃用 - 自 laravel 5.3 - Route::controllers：

Route::resource('datatables', 'DatatablesController', [
    'anyData'  => 'datatables.data',
    'getIndex' => 'datatables',
]);

对如何正确编写路线有什么建议吗？

PS.: 我已经使用了composer dumpautoload, composer install & composer update 并没有改变错误

更新

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);
    

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>

【参考方案1】：

需要使用 artisan 生成资源控制器

php artisan make:controller DatatablesController --resource

创建控制器将具有您的资源路由所需的方法

more info

注意：第三个参数（数组）无效

【讨论】：

感谢您的回复！我生成了资源控制器。如何，正确的控制器和路线应该是什么样子？恳请您提供示例代码。

控制器看起来像生成的控制器，在路由集合中你应该删除第三个参数，我不知道你在做什么

请看上面我对当前控制器的更新。我基本上想加载索引页面并使用函数anyData加载axjax请求。

如果你有自定义方法，你需要自定义路由

Route::get('datatables/data', 'DatatablesController@getIndex')->name('datatables.data')

【参考方案2】：

在你的 routes.php 中，Laravel 搜索一个控制器（在你的例子中是 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 会尝试执行 index 方法。就像@madalinivascu 写的那样，这个控制器需要存在。
