我的laravel4应用程序中有一个小型图像生成器。生成图像大约需要700毫秒,因此我开始在服务器上缓存生成的结果,并将其返回给浏览器,这样可以节省一些时间。
由于图像一旦生成就永远不会改变,所以我想告诉浏览器在本地缓存图像,并使用以下代码完成了此操作:
$path = $cacheFolderPath . $cacheFileName;
if (File::exists( $path )){
$response = Response::make(File::get($path));
$response->header('Content-Type', 'image/png');
$response->header('Content-Disposition', 'inline; filename="'.$cacheFileName.'"');
$response->header('Content-Transfer-Encoding', 'binary');
$response->header('Cache-Control', 'public, max-age=10800, pre-check=10800');
$response->header('Pragma', 'public');
$response->header('Expires', date(DATE_RFC822,strtotime(" 2 day")) );
$response->header('Last-Modified', date(DATE_RFC822, File::lastModified($path)) );
$response->header('Content-Length', filesize($path));
return $response;
}
