我有一个使用Assetic将一些CSS文件生成到磁盘的类。我将直接进入代码。
在我的布局头部,我正在这样做:
$assetify = new Assetify();
$assetify->setDebug(true);
$assetify->setAssetDirectory(BASE_DIR . '/public/assets');
$assetify->setOutputDirectory(BASE_DIR . '/public/assets/generated');
$assetify
->addStylesheet('/assets/css/bootstrap-2.3.2.css')
->addStylesheet('/assets/css/select2-3.4.3.css')
->addStylesheet('/assets/css/main.css');
echo $assetify->dump();
我的“Assetify”类通过Assetic运行此项任务。我将从dump()
函数中复制我希望是相关部分的代码:
// The Asset Factory allows us to not have to do all the hard work ourselves.
$factory = new AssetFactory($this->assetDirectory, $this->debug);
$factory->setDefaultOutput('/generated/*.css');
// The Filter Manager allows us to organize filters for the asset handling.
// For other filters, see: https://github.com/kriswallsmith/assetic
$fm = new FilterManager();
$fm->set('yui_css', new Yui\CssCompressorFilter('/usr/local/bin/yuicompressor-2.4.7.jar'));
$fm->set('yui_js', new Yui\JsCompressorFilter('/usr/local/bin/yuicompressor-2.4.7.jar'));
$factory->setFilterManager($fm);
// The Asset Manager allows us to keep our assets organized.
$am = new AssetManager();
$factory->setAssetManager($am);
// The cache-busting worker prefixes every css with what amounts to a version number.
$factory->addWorker(new CacheBustingWorker());
$assetCollection = array();
foreach ($assetGroups as $assetGroup) {
foreach ($assetGroup as $media => $items) {
$fileCollection = array();
foreach ($items as $item) {
// Add this asset to the asset collection.
$fileCollection[] = new FileAsset($item);
}
$assetCollection[] = new AssetCollection($fileCollection);
}
}
$assetCollection = new AssetCollection($assetCollection);
$am->set('base_css', $assetCollection);
// Generate the required assets. Prefixing a filter name with a question mark
// will cause that filter to be omitted in debug mode.
$asset = $factory->createAsset(
array('@base_css'),
array('?yui_css')
);
// Configure an internal file system cache so we don't regenerate this file on every load.
$cache = new AssetCache(
$asset,
new FilesystemCache($this->outputDirectory)
);
// And generate static versions of the files on disk.
$writer = new AssetWriter($this->assetDirectory);
$writer->writeAsset($cache);
这将生成两个不同的文件,
87229eb-f47a352.css
和a37c1589762f39aee5bd24e9405dbdf9
。这两个文件的内容完全相同。87229eb-f47a352.css
文件似乎每次都会被生成,而除非文件内容发生更改(这就是我想要的),否则不会重新生成另一个文件。如果我注释掉 $writer->writeAsset($cache)
,那么就不会写入任何文件到磁盘中。
我缺少了什么明显的配置?感谢您的帮助,谢谢。
