将变量从路由组传递到 Laravel 4 中的路由函数

Passing variables from route group to route functions in Laravel 4

提问by Inigo

I have one installation of Laravel on which I wish to run 3 sites (addon domains). I am using Laravel's route grouping method to grab each domain. However, I need to be able to know which domain I am working with inside of each group. What is the best way to do this? I have the following code:

我有一个 Laravel 安装，我希望在其上运行 3 个站点（附加域）。我正在使用 Laravel 的路由分组方法来获取每个域。但是，我需要能够知道我在每个组内使用哪个域。做这个的最好方式是什么？我有以下代码：

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

^ Which doesn't work.

^ 这不起作用。

The notessuggest using wildcards in the URL, eg.

该票据建议在网址中使用通配符，例如。

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

However, I would prefer a different method, as I can't really use this during development on my local server. Is there any way that is more like my first method, in which I can just manually declare a key for each domain?

但是，我更喜欢不同的方法，因为在本地服务器上的开发过程中我无法真正使用它。有什么方法更像我的第一种方法，我可以在其中手动为每个域声明一个键？

EDIT: I also then need to pass that domain variable to a controller, which I am also struggling to work out how to do?

编辑：然后我还需要将该域变量传递给控制器​​，我也在努力解决如何做？

Thanks.

谢谢。

My problem is that I am not using subdomains, I am using domains; I have 3 separate domains for 3 sister sites that are running on the same installation of Laravel. So I have 3 route groups, one for each domain. Moreover, I don't want to requestthe domain variable using {domain}.comeach time, I want to tellLaravel the domain in each case, then pass that domain as a variable to the appropriate controller within each group. Here is my example code:

我的问题是我没有使用子域，我使用的是域；我有 3 个单独的域，用于运行在同一 Laravel 安装上的 3 个姐妹站点。所以我有 3 个路由组，每个域一个。此外，我不想每次都请求域变量{domain}.com，我想在每种情况下告诉Laravel 域，然后将该域作为变量传递给每个组内的适当控制器。这是我的示例代码：

$domain1 = 'domain1.com';
$domain2 = 'domain2.com';
$domain3 = 'domain3.com';

Route::group(array('domain' => $domain1), function(){
    Route::get('/', 'PrimaryController@somefunction1');  // <-- I want to access $domain1 in my controller
});
Route::group(array('domain' => $domain2), function(){
    Route::get('/', 'PrimaryController@somefunction2');  // <-- ...and $domain2
});
Route::group(array('domain' => $domain3), function(){
    Route::get('/', 'PrimaryController@somefunction3');  // <-- ...and $domain3
});

This is an option for your first method:

这是您的第一种方法的一个选项：

$domain = 'domainone';
Route::group(array('domain' => $domain.'.com'), function() use ($domain)
{
    Route::get('/', function() use ($domain) {
         echo "$domain";
    });
});

You can pass watever you like to your controllers, via groups too, you just need to add one more level.

您可以通过组将任何您喜欢的水传递给您的控制器，您只需要再添加一个级别。

$subdomain = 'atlanta';
$domain = 'domainone';

Route::group(array('domain' => "$subdomain.$domain.com"), function()
{
    Route::group(array('domain' => '{subdomain}.{domain}.com'), function()
    {
        Route::get('testdomain', function($subdomain, $domain) {
            dd("closure: subdomain: $subdomain - domain: $domain");
        });

        Route::get('testdomaincontroller', 'FooController@index');
    });
});

By doing this you have to understand that your first two variables passed to your controller action will always be $subdomain and $subdomain. Here's a controller to show it, which you can use to test those routes too:

通过这样做，您必须了解传递给控制器​​操作的前两个变量将始终是 $subdomain 和 $subdomain。这是一个显示它的控制器，您也可以使用它来测试这些路由：

class FooController extends Controller {

    public function index($subdomain, $domain)
    {
        dd("controller: subdomain: $subdomain - domain: $domain");
    }
}

You'll have two different routes with this:

您将有两条不同的路线：

http://yourdomain.dev/testdomain
http://yourdomain.dev/testdomaincontroller

I accomplish this with the following two steps:

我通过以下两个步骤完成此操作：

First, using the Laravel documentation example, I pull the subdomain down and assign it to {account}.

首先，使用 Laravel 文档示例，我拉下子域并将其分配给 {account}。

Route::group(array('domain' => '{account}.myapp.com'), function()

From here, any controller you assign to a route within this groupwill have the ability to inject this {account}data in to its functions.

从这里开始，您分配给该组内路由的任何控制器都可以将此{account}数据注入其功能。

Note: you can'taccess it in the constructor. Each function in the Controller that needs to use this data will need a parameter created for it. Like this:

注意：您不能在构造函数中访问它。Controller 中需要使用此数据的每个函数都需要为其创建一个参数。像这样：

/**
 * The $subdomain variable below will capture the data stored in  
 * {account} in your route group.  Note that you can name this variable 
 * anything you'd like.
 */
public function showCreateBankAccount($subdomain) { 

   echo "This is your subdomain: " . $subdomain;

}
