将Laravel 4.2升级到5.0，获得[ReflectionException]类App \ Http \ Controllers \ PagesController不存在

问题描述

我正在将我的项目从laravel 4.2更新到laravel 5.0.但是，在我遇到此错误并在过去4个小时内一直尝试解决该错误之后.

I was updating my project from laravel 4.2 to laravel 5.0. But, after I am facing this error and have been trying to solve it for the past 4 hours.

我在4.2版本上没有遇到任何类似的错误.我尝试过作曲家dump-autoload没有任何效果.

I didn't face any error like this on the 4.2 version. I have tried composer dump-autoload with no effect.

如更新指南中所述，我已经按原样移动了所有控制器，并将app/Providers/RouteServiceProvider.php中的namespace属性设置为null.因此，我想我所有的控制器都在全局名称空间中，因此不需要在任何地方添加路径.

As stated in the guide to update, I have shifted all the controllers as it is, and made the namespace property in app/Providers/RouteServiceProvider.php to null. So, I guess all my controllers are in global namespace, so don't need to add the path anywhere.

这是我的composer.json:

Here is my composer.json:

"autoload": {
    "classmap": [
        "app/console/commands",
        "app/Http/Controllers",
        "app/models",
        "database/migrations",
        "database/seeds",
        "tests/TestCase.php"
    ],

页面控制器:

<?php
class PagesController extends BaseController {

  protected $layout = 'layouts.loggedout';

  public function getIndex() {
    $categories = Category::all();

    $messages = Message::groupBy('receiver_id')
                ->select(['receiver_id', DB::raw("COUNT('receiver_id') AS total")])
                ->orderBy('total', 'DESC'.....

这里是BaseController.

And, here is BaseController.

<?php

class BaseController extends Controller {

    //Setup the layout used by the controller.
    protected function setupLayout(){
        if(!is_null($this->layout)) {
            $this->layout = View::make($this->layout);
        }
    }

}

在routes.php中，我按如下方式调用控制器:

In routes.php, I am calling controller as follows :

Route::get('/', array('as' => 'pages.index', 'uses' => 'PagesController@getIndex'));

任何人都请帮忙.过去几个小时，我一直在挠头.

Anyone please help. I have been scratching my head over it for the past few hours.

推荐答案

路由已加载到 app/Providers/RouteServiceProvider.php 文件中.如果您在其中查看，则会看到以下代码块:

Routes are loaded in the app/Providers/RouteServiceProvider.php file. If you look in there, you’ll see this block of code:

$router->group(['namespace' => $this->namespace], function($router)
{
    require app_path('Http/routes.php');
});

这会将名称空间添加到任何路由中，默认情况下为App\Http\Controllers，因此会出现错误消息.

This prepends a namespace to any routes, which by default is App\Http\Controllers, hence your error message.

您有两个选择:

1. 在控制器顶部添加适当的名称空间.
2. 加载组中外部的路由，因此不会自动添加名称空间.

1. Add the proper namespace to the top of your controllers.
2. Load routes outside of the group, so a namespace isn’t automatically prepended.

我会选择选项#1，因为从长远来看，它可以避免您的头痛.

I would go with option #1, because it’s going to save you headaches in the long run.
