Laravel 4 中未找到控制器类

Controller class not found in Laravel 4

提问by Deepak Goyal

I have the following error while trying to run my controller

尝试运行控制器时出现以下错误

Controller class not found

找不到控制器类

I have this code in my routes.phpfile

我的routes.php文件中有此代码

Route::get('cms/create-page', 'AdminCMSController@create_page');
Route::post('cms/createpage','AdminCMSController@createpage');
Route::controller('cms','AdminCMSController');

And this is the code in my Controller

这是我的控制器中的代码

class AdminCMSController extends BaseController {
    public function create_page() {
    }

    public function createpage() {
    }
}

How can I fix it?

我该如何解决？

If you didn't move the controllersdirectory from the original location (which is ?project_root?/app/controllers/, you must guarantee that:

如果您没有controllers从原始位置移动目录（即?project_root?/app/controllers/，您必须保证：

1. Laravel's autoload has the controllerdirectory. Navigate to ?project_root?/app/start/global.php. You need to have something like this:

   (...)
   ClassLoader::addDirectories(array(
       app_path().'/commands',
       app_path().'/controllers',
       app_path().'/models',
       app_path().'/database/seeds',
   ));
   (...)
   

   Take notice to this line app_path().'/controllers'. It must exist.

2. Also, open your composer.jsonfile and verify that the following lines exist:

   (...)
   "autoload": {
       "classmap": [
           "app/commands",
           "app/controllers",
           "app/database/migrations",
           "app/database/seeds",
           "app/tests/TestCase.php"
       ],
   (...)
   

   Make sure that you have the line with app/controllers

1. Laravel 的自动加载有controller目录。导航到?project_root?/app/start/global.php。你需要有这样的东西：

   (...)
   ClassLoader::addDirectories(array(
       app_path().'/commands',
       app_path().'/controllers',
       app_path().'/models',
       app_path().'/database/seeds',
   ));
   (...)
   

   注意这条线app_path().'/controllers'。它必须存在。

2. 此外，打开您的composer.json文件并验证以下行是否存在：

   (...)
   "autoload": {
       "classmap": [
           "app/commands",
           "app/controllers",
           "app/database/migrations",
           "app/database/seeds",
           "app/tests/TestCase.php"
       ],
   (...)
   

   确保你有这条线 app/controllers

If you have this lines and you still get the same message, go to your project root and run the following command from the command-line composer dumpautoload -o.

如果您有这些行并且仍然收到相同的消息，请转到您的项目根目录并从命令行运行以下命令composer dumpautoload -o。

Laravel works with Composer, which is a dependency management tool for PHP. It also prepares an autoload file for all your project classes (see composer docs). When you run the composer dumpautoloadcommand, it will create some files within ?project_root?/vendor/composer.

Laravel 与Composer一起工作，Composer是 PHP 的依赖管理工具。它还为您的所有项目类准备一个自动加载文件（请参阅 composer docs）。当您运行该composer dumpautoload命令时，它会在?project_root?/vendor/composer.

Make sure that you can find the class AdminCMSControllerin the file ?project_root?/vendor/composer/autoload_classmap.php. You should see something like this:

确保您可以AdminCMSController在文件中找到该类?project_root?/vendor/composer/autoload_classmap.php。您应该会看到如下内容：

'AdminCMSController' => $baseDir . '/app/controllers/AdminCMSController.php',

If you have changed the default location of your controllersdirectory, you have to do either one of the following steps. However, since you are not defining a namespace in your class, it doesnt seem likely that this is your problem:

如果您更改了controllers目录的默认位置，则必须执行以下任一步骤。但是，由于您没有在类中定义命名空间，因此这似乎不是您的问题：

1. Use PSR-0for autoloading classes. Imagine that you have the following folder structure:

   /app
       /commands
       /config
       /database
       /Acme
           /controllers
   

   You have to specify the Acmefolder in your composer.json, like this:

   "autoload": {
       "classmap": [
           "app/commands",
           "app/database/migrations",
           "app/database/seeds",
           "app/tests/TestCase.php"
       ],
       "psr-0": {
           "Acme": "app/"
       }
   },
   

   After this you need to update you composer autoload files with the command composer dumpautoload.

2. If you do not want to use the PSR-0 for autoloading, you need to change your routes file from this

   Route::controller('cms','AdminCMSController');
   

   to this:

   Route::controller('cms','Acme\controllers\AdminCMSController');
   

1. 使用PSR-0自动加载类。假设您有以下文件夹结构：

   /app
       /commands
       /config
       /database
       /Acme
           /controllers
   

   您必须Acme在您的 中指定文件夹composer.json，如下所示：

   "autoload": {
       "classmap": [
           "app/commands",
           "app/database/migrations",
           "app/database/seeds",
           "app/tests/TestCase.php"
       ],
       "psr-0": {
           "Acme": "app/"
       }
   },
   

   在此之后，您需要使用命令更新您的 Composer 自动加载文件composer dumpautoload。

2. 如果您不想使用 PSR-0 进行自动加载，则需要从此更改您的路由文件

   Route::controller('cms','AdminCMSController');
   

   对此：

   Route::controller('cms','Acme\controllers\AdminCMSController');
   

IF you use PSR-0, you need to namespace your classes like this:

如果你使用 PSR-0，你需要像这样为你的类命名：

<?php namespace Acme\controllers;

class AdminCMSController extends BaseController {
(...)
}

^{Curious about the Acmereference? I was too. Refer to the wikipedia.}

^{对Acme参考感到好奇？我也是。请参阅维基百科。}
