CssRewrite过滤器不会将相对url转换为绝对

Question

我试图将所有使用的css文件合并为一个。但是包含相对路径的资源会导致问题。我试过资产的CssRewriteFilter，但它不起作用。

这里是我的代码：

$files = [ 
     '/node_modules/select2/dist/css/select2.min.css', 
     '/node_modules/jquery-datetimepicker/jquery.datetimepicker.css', 
     '/node_modules/icheck/skins/square/blue.css', 
     '/node_modules/Plupload/js/jquery.plupload.queue/css/jquery.plupload.queue.css', 
     '/node_modules/pace/themes/white/pace-theme-flash.css', 
     '/node_modules/lightgallery/dist/css/lightgallery.min.css', 
     '/node_modules/x-editable/dist/bootstrap3-editable/css/bootstrap-editable.css', 
     '/node_modules/sweetalert2/dist/sweetalert2.css', 
     '/node_modules/animate.css/animate.min.css', 
     '/node_modules/fullcalendar/dist/fullcalendar.min.css', 
     '/node_modules/flag-icon-css/css/flag-icon.min.css', 
     '/theme/assets/skin/default_skin/css/theme.css', 
    ]; 

    $am = new \Assetic\AssetManager(); 

    $items = []; 

    foreach ($files as $file) { 
     $filename = APP_ROOT_DIR . '/public/ui' . $file; 
     $items[] = new \Assetic\Asset\FileAsset($filename, [new \Assetic\Filter\CssRewriteFilter()]); 
    } 

    $collection = new \Assetic\Asset\AssetCollection(
     $items 
    ); 
    $collection->setTargetPath('vendor.css'); 

    $am->set('collection', $collection); 

    $writer = new \Assetic\AssetWriter(APP_ROOT_DIR . '/public/ui/shared/css/'); 
    $writer->writeManagerAssets($am); 

我期待什么：

当IMG是/node_modules/test/css/test.css包含../img/test.png代码Assetic应该把它改写为/node_modules/test/img/test.png

尝试构建您的FileAsset类像：

new \Assetic\Asset\FileAsset(
    $filename, 
    [new \Assetic\Filter\CssRewriteFilter()], 
    '/node_modules/test/' 
); 

在src/Assetic/Asset/FileAsset.php:37中，我们看到您可以包含$sourcePath作为第三个参数。

https://github.com/kriswallsmith/assetic/blob/master/src/Assetic/Asset/FileAsset.php#L37

您可能要rejig您$files阵列像

$files = [ 
    ['/node_modules/select2/dist/css/', 'select2.min.css'] 
    ... 
]; 

所以，你可以调用$sourcePath过两次类似

new \Assetic\Asset\FileAsset(
    APP_ROOT_DIR . '/public/ui' . $file[0].$file[1], 
    [new \Assetic\Filter\CssRewriteFilter()], 
    '/public/ui'.$filename[0] 
);
