How to use subdomain in laravel 4?
提问by Kapil Gupta
I want to detect subdomains in routes.php in my L4 website and want to store that subdomain value somewhere so that I can access that value in each controller.
我想在我的 L4 网站的 routes.php 中检测子域，并希望将该子域值存储在某处，以便我可以在每个控制器中访问该值。
How can I do that ? Please help
我怎样才能做到这一点 ？请帮忙

Route::group(array('domain' => '{account}.myapp.com'), function() {
Route::get('user/{id}', function($account, $id) {
//
});
});

You can put this type of method in routes. However, I think it's a better fit for a filter in the 'app/filters.php' file. Try this:
您可以将这种类型的方法放在路由中。但是，我认为它更适合“app/filters.php”文件中的过滤器。尝试这个：
Route::filter('getSubdomain', function($route, $request)
{
$host = $request->getHost();
$parts = explode('.', $host);
$subdomain = $parts[0];
// Store subdomain in session
Session::put('subdomain', $subdomain);
});
Then add the filter to the route (probably a group route) as follows:
然后将过滤器添加到路由（可能是组路由）中，如下所示：
Route::group(array('before' => 'getSubdomain'), function()
{
... add route stuff here ..
});

You can use Request to get your domain anywhere.
您可以使用 Request 在任何地方获取您的域。
So, create a BaseController and add a method to get the current domain on all your extended controllers:
因此，创建一个 BaseController 并添加一个方法来获取所有扩展控制器上的当前域：
class BaseController extends Controller {
public function getDomain()
{
return Request::getHost();
}
}
And use it:
并使用它：
class PostsController extends BaseController {
public function store()
{
$post = new Post;
$post->domain_id = Domain::where('name', $this->getDomain())->first()->id;
$post->save();
}
}
Of course, this controller example supposes that you have a Domain model:
当然，这个控制器示例假设您有一个域模型：
class Domain extends Eloquent {
private $table = 'domains';
}
EDIT:
编辑：
Unless you have a very good reason for it, you don't have to use routes or store your subdomain on a session, unless you have a reallygood reason for this, it's a smell. Take a look at Laravel's code, there only one session stored by it: Laravel's session.
除非你有一个很好的理由，你不必使用路由或您的子存储在一个会话，除非你有一个真正好的理由，这是一个味道。看一下 Laravel 的代码，它只存储了一个会话：Laravel 的会话。
You can create a helper function:
您可以创建一个辅助函数：
Create a app/helpers/functions.php file (this is just an example) and add this helper function there:
创建一个 app/helpers/functions.php 文件（这只是一个例子）并在那里添加这个辅助函数：
function getCurrentSubdomain()
{
$domain = Config::get('app.domain');
preg_match("/^(.*)(\.$domain)$/", Request::getHost(), $parts);
return $parts[1];
}
Open your app/config/app.php and add a domain configuration to it:
打开您的 app/config/app.php 并向其添加域配置：
return array(
'domain' => 'myapp.com',
...
);
Add the file to the autoload section of your composer.json:
将文件添加到 composer.json 的自动加载部分：
"autoload": {
"classmap": [
...
],
"files": [
"app/helpers/functions.php"
]
},
Then you can use it everywhere: controllers, classes, routers, etc. Here's the same example as before, using it:
然后你就可以在任何地方使用它：控制器、类、路由器等。 这是和之前一样的例子，使用它：
class PostsController extends BaseController {
public function store()
{
$post = new Post;
$post->domain_id = Domain::where('name', getCurrentSubdomain())->first()->id;
$post->save();
}
}
You can also create a class and a Facade for it, so you can call this class from anywhere, like Laravel does:
你还可以为它创建一个类和一个 Facade，这样你就可以从任何地方调用这个类，就像 Laravel 那样：
Helper::getCurrentSubdomain();
Or you can do the same by just creating a class and create a static function (less testable).
或者您可以通过创建一个类并创建一个静态函数（较少可测试）来做同样的事情。

This is working on my Laravel 4.2 right now.
这现在正在我的 Laravel 4.2 上工作。
On your routes file:
在您的路线文件中：
Route::group(['domain' => '{subdomain}.myapp.com'], function()
{
Route::get('/', function($subdomain)
{
return "Your subdomain is: ".$subdomain;
});
});
Get subdomain in your controllers or anywhere:
在您的控制器或任何地方获取子域：
$subdomain = Route::getCurrentRoute()->getParameter('subdomain');
