这取决于你想怎么做。

例如，如果您仍在使用akamai的CCU或快速清除功能。

如果您使用的是CCU或快速清除，那么最好的办法是将所有图像标记为专用的CP代码。完成后，您可以清除CP代码，该代码将实习清除所有图像。

您可以参考CCU的几个有用文件： https://developer.akamai.com/api/purge/ccu-v2/overview.html

快速清除： https://control.akamai.com/dl/customers/FIMA/Fast-Purge-QuickRef.pdf https://github.com/akamai-open/api-kickstart/tree/master/examples
