Zend framework neilime/zf2资产包和Base64资产

有人知道怎么做吗

在css中

background:url("data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAwAAAAMCAYAAABWdVznAAAAYUlEQVR42mP4////P1IwA5RBNIBr+Pj5+/9Tlx78v373OYoCkBgIY2gACWr7tP63CO8BanoBlmyfuQssBsIYGtAVLNpwEsMADA0gAFMIw+hOpEwDSU4i2dMkByvJEUcsAABHaALCQIZDrAAAAABJRU5ErkJggg==");

错误：

 Fatal error: Uncaught exception 'LogicException' with message `'"data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAwAAAAMCAYAAABWdVznAAAAYUlEQVR42mP4////P1IwA5RBNIBr+Pj5+/9Tlx78v373OYoCkBgIY2gACWr7tP63CO8BanoBlmyfuQssBsIYGtAVLNpwEsMADA0gAFMIw+hOpEwDSU4i2dMkByvJEUcsAABHaALCQIZDrAAAAABJRU5ErkJggg==" has not been cached as file "public/cache/data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAwAAAAMCAYAAABWdVznAAAAYUlEQVR42mP4////P1IwA5RBNIBr+Pj5+/9Tlx78v373OYoCkBgIY2gACWr7tP63CO8BanoBlmyfuQssBsIYGtAVLNpwEsMADA0gAFMIw+hOpEwDSU4i2dMkByvJEUcsAABHaALCQIZDrAAAAABJRU5ErkJggg=="' in vendor/neilime/zf2-assets-bundle/src/AssetsBundle/Service/Service.php on line 855`

对于这种png格式的Base64编码媒体，是否有内置的解决方案？

错误已修复，并按预期工作。
