＆＃34;您还可以使用App facade上的setLocale方法在运行时更改活动语言：＆＃34; https://laravel.com/docs/5.3/localization#introduction

 public static void main(String[] args){
    File file=new File(XmlProcessing.class.getResource("InputXml.txt").getFile());
    // create a new DocumentBuilderFactory
      DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
      try{
    DocumentBuilder  docBuilder = docBuilderFactory.newDocumentBuilder();
    Document document = docBuilder.parse(file);
    System.out.println("Before removing the Node:-");
    printDocument(document, System.out);
    NodeList tagList = document.getElementsByTagName("tag_name");
        Element elemToBeRemoved = (Element)tagList.item( 0 );
        Node prevElem = elemToBeRemoved.getPreviousSibling();
        if (prevElem != null && 
            prevElem .getNodeType() == Node.TEXT_NODE &&
            prevElem .getNodeValue().trim().length() == 0) {
            elemToBeRemoved.getParentNode().removeChild(prevElem );
        }
        elemToBeRemoved.getParentNode().removeChild( elemToBeRemoved );  
       System.out.println("\nAfter removing the node:-");
        printDocument(document, System.out);


      }catch(Exception excep){
          excep.printStackTrace();
      }

}
public static void printDocument(Document doc, OutputStream out) throws IOException, TransformerException {
    TransformerFactory tf = TransformerFactory.newInstance();
    Transformer transformer = tf.newTransformer();
    transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "no");
    transformer.setOutputProperty(OutputKeys.METHOD, "xml");
    transformer.setOutputProperty(OutputKeys.INDENT, "yes");
    transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
    transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "4");

    transformer.transform(new DOMSource(doc), 
         new StreamResult(new OutputStreamWriter(out, "UTF-8")));
}


/** Output:-
Before removing the Node:-
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<root>
    <tag_name>text</tag_name>
    <tag_name>text</tag_name>
    <tag_name>text</tag_name>
</root>

After removing the node:-
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<root>
    <tag_name>text</tag_name>
    <tag_name>text</tag_name>
</root>

*/

如果我们有类似的东西，我们如何使用$ locale：

Route::get('welcome/{locale}', function ($locale) {
    App::setLocale($locale);

    //
});

Answer 1

问题在于路线参数不是本地化

由于你期望路线有两个参数，你应该通过两个参数来进行闭合。

Route::get('posts/{post}/comments/{comment}', function ($postId, $commentId) { 
    // 
});

在你的例子中

Route::group(['prefix' => 'admin/{id}/{locale}', 'namespace' => 'Admin'], function( $id, $locale ) { 
    // this does not work.
    App::setLocale( $locale ); 
    // this does work.
    App::setLocale( Request::segment( 3 ) );
    Route::resource('product', 'ProductController', ['except' => [ 'show' ]]);
});

请注意 - Route::group回调会对任何请求执行（即使不是您的前缀！）。 Route::group与Route::get/post/match不相似，它就像是内部获取/发布/匹配调用的助手。

App::setLocale( $locale );不起作用，因为Laravel仅将Illuminate\Routing\Router的实例传递到群组的回调中。在此阶段，尚未提取locale前缀，甚至尚未处理URL。

App::setLocale( Request::segment( 3 ) );将针对＆＃39;一/二/三＆＃39;执行用＆＃39;三＆＃39;作为一个地区。

你的榜样应该是：

Route::group(['prefix' => 'admin/{id}/{locale}', 'namespace' => 'Admin'], function() {
    // test a locale
    Route::get('test', function($locale){ echo $locale; });

    // ProductController::index($locale)
    Route::resource('product', 'ProductController', ['except' => [
        'show'
    ]]);
});

因此，只需更新您的ProductController并添加$ locale作为参数。

备选方案：如果您希望setLocale在一个地方更新您的路线：

// set locale for '/admin/anything/[en|fr|ru|jp]/anything' only
if (Request::segment(1) === 'admin' && in_array(Request::segment(3), ['en', 'fr', 'ru', 'jp'])) {
    App::setLocale(Request::segment(3));
} else {
    // set default / fallback locale
    App::setLocale('en');
}

Route::group(['prefix' => 'admin/{id}/{locale}', 'namespace' => 'Admin'], function() {
    Route::resource('product', 'ProductController', ['except' => [
        'show'
    ]]);
});

使用Route :: group，prefix和namespace进行Laravel本地化
