Laravel中如何配置多语言国际化路由
问题
假设我们有一个网站：example.com，现在我们想拥有URL被翻译过的多个国际化站点，比如example.cn，example.fr，example.it等。访问example.com/hello的时候应该在站点头部标签中生成如下hreflang属性：
link rel="alternate" hreflang="it" href="http://example.it/ciao"link rel="alternate" hreflang="it" href="http://example.cat/hola"
代码
1、在BaseController中，新增如下方法：
// app/Controller/BaseController.php
protected static function geti18nUrls()
{
$domains = Config::get('i18n.sites');
$translatedUrls = array();
//Backup current locale
$currentLocale = App::getLocale();
foreach($domains as $domain => $locale)
{
$protocol = (in_array($domain,Config::get('sites.https'),true)) ? 'https://' : 'http://';
App::setLocale($locale);
$routeName = Route::currentRouteName();
if( $routeName != 'index' )
{
$translatedUrls[$domain] = $protocol.$domain.'/'.Lang::get('routes.'.$routeName) ;
}
else
{
$translatedUrls[$domain] = $protocol.$domain;
}
}
App::setLocale($currentLocale);
return $translatedUrls;
}
2、在config目录下创建一个新的配置文件i18n.php：
// Create a i18n file
// app/config/i18n.php
return array
(
'https' => array(), //list of domains with https support.
'sites' => array(
'example.it',
'example.cat',
'example.com',
),
);
3、并且我们假设你已经对所有路由进行了翻译
// routes.php
switch($_SERVER['HTTP_HOST'])
{
case 'example.com':
App::setLocale('en');
break;
case 'example.it':
App::setLocale('it');
break;
case 'example.cat':
App::setLocale('ca');
break;
}
Route::any(Lang::get('routes.hello'),
array('as' => 'hello', 'uses' => 'HomeController@hello'));
4、创建翻译文件resources/lang/en/routes.php，resources/lang/it/routes.php，resources/lang/ca/routes.php：
//lang/en/routes.php
return array
(
'hello' => '/hello'
);
//lang/it/routes.php
return array
(
'hello' => '/ciao'
);
//lang/ca/routes.php
return array
(
'hello' => '/hola'
);
使用
在所有控制器中调用该方法并渲染相应视图：
// app/controllers/ExampleController.php
class ExampleController extends BaseController
{
public function hello()
{
$this->layout->with( 'hreflang', self::geti18nUrls() );
$this->layout->content = View::make( 'hello_view' );
}
}
编写模板文件hello_view.php：
<!-- app/views/hello_view.blade -->
<head>
<link rel="alternate" hreflang="it" href="{{ hreflang['example.it'] }}" >
<link rel="alternate" hreflang="ca" href="{{ hreflang['example.cat'] }}" >
</head>
