Adding a new config file in Laravel 5 not working
提问by geoffs3310
I want a new config file in my Laravel 5 app to store all my constants in. After looking around the net I found the recommended solution seems to be to create a new config file that returns an array of key value pairs and then use that. So I created the following file:
我想在我的 Laravel 5 应用程序中创建一个新的配置文件来存储我的所有常量。在环顾网络后，我发现推荐的解决方案似乎是创建一个新的配置文件，该文件返回一组键值对，然后使用它。所以我创建了以下文件：
<?php
// config/constants.php
return [
'SITE_NAME' => 'Site Name',
'SITE_EMAIL' => '[email protected]',
'ADMIN_EMAIL' => '[email protected]'
];
Then in one of my controllers I try to access one of these values like so:
然后在我的一个控制器中，我尝试访问这些值之一，如下所示：
echo Config::get('constants.ADMIN_EMAIL');
I just get the following error:
我只是收到以下错误：
FatalErrorException in WelcomeController.php line 46:
Class 'App\Http\Controllers\Config' not found
Do I have to do something else to get it to work?
我是否必须做其他事情才能使其正常工作？

In Laravel 5, to avoid this kind of headache, you can use the confighelper function to get a config item, like this :
在 Laravel 5 中，为了避免这种头痛，您可以使用confighelper 函数来获取配置项，如下所示：
config('constants.ADMIN_EMAIL')
config('constants.ADMIN_EMAIL')
Nice and easy ;)
好，易于 ;）

The Configclass is an alias in the global namespace. To reference it from inside the controller (which is in the App\Http\Controllersnamespace) you have to prepend it with a backslash:
该Config班是全局命名空间的别名。要从控制器内部（在App\Http\Controllers命名空间中）引用它，您必须在它前面加上一个反斜杠：
echo \Config::get('constants.ADMIN_EMAIL');
Or add a usestatement above the controller class:
或者use在控制器类上面添加一条语句：
use Config;
class MyController extends Controller {
As an alternative you might also want to use dependency injectionto access the config. That would look somewhat like this:
作为替代方案，您可能还想使用依赖注入来访问配置。这看起来有点像这样：
class MyController extends Controller {
public function __construct(Illuminate\Config\Repository $config){
$this->config = $config;
}
public function index(){
echo $this->config->get('constants.ADMIN_EMAIL');
}
}
As @Bernig suggests you can also simply use the new config()helper function:
正如@Bernig 建议的那样，您也可以简单地使用新的config()辅助函数：
echo config('constants.ADMIN_EMAIL');

I met the same issue today, and I find an elegant solution:
add the config/your_new_config.phpto ConfigServiceProvider, like this:
我今天遇到了同样的问题，我找到了一个优雅的解决方案：添加config/your_new_config.phpto ConfigServiceProvider，如下所示：
/**
* Overwrite any vendor / package configuration.
*
* This service provider is intended to provide a convenient location for you
* to overwrite any "vendor" or package configuration that you may want to
* modify before the application handles the incoming request / command.
*
* @return void
*/
public function register()
{
config([
'config/your_new_config.php', // add your new config file here!
]);
}
The reason is well explained in the function's comments
原因在函数的注释中有很好的解释
