Magento CSS文件合并将主机名假装成我的data-uris,因为Mage_Core_Model_Design_Package
(beforeMergeCss
)中的RegEx 无法正常工作。它应该在主机名之前添加相对的图像路径,但不能在数据URI之前。
$cssUrl = '/url\\(\\s*(?!data:)([^\\)\\s]+)\\s*\\)?/';
$contents = preg_replace_callback($cssUrl, array($this, '_cssMergerUrlCallback'), $contents);
CSS代码:
background: #fafafa url("data:image/svg+xml;base64, PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIHZlcnNpb249IjEuMSIgeD0iMHB4IiB5PSIwcHgiIHdpZHRoPSI2cHgiIGhlaWdodD0iM3B4IiB2aWV3Qm94PSIwIDAgNiAzIiBlbmFibGUtYmFja2dyb3VuZD0ibmV3IDAgMCA2IDMiIHhtbDpzcGFjZT0icHJlc2VydmUiPjxwb2x5Z29uIHBvaW50cz0iNS45OTIsMCAyLjk5MiwzIC0wLjAwOCwwICIvPjwvc3ZnPg==") no-repeat;
合并后的结果:
background: #fafafa url("http://shop12.dev/skin/frontend/shop/default/styles/data:image/svg+xml;base64")PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIHZlcnNpb249IjEuMSIgeD0iMHB4IiB5PSIwcHgiIHdpZHRoPSI2cHgiIGhlaWdodD0iM3B4IiB2aWV3Qm94PSIwIDAgNiAzIiBlbmFibGUtYmFja2dyb3VuZD0ibmV3IDAgMCA2IDMiIHhtbDpzcGFjZT0icHJlc2VydmUiPjxwb2x5Z29uIHBvaW50cz0iNS45OTIsMCAyLjk5MiwzIC0wLjAwOCwwICIvPjwvc3ZnPg==") no-repeat;
如何避免这种情况?我找不到如何纠正所用RegEx的合奏的方法。(对我来说,使用GIF并不是真正的解决方案)
