Tencent EdgeOne Cache Purge WordPress Plugin (Free Available) - Automatic Refresh + Manual Control Tutorial

Recently, I changed the website server and started using Tencent's EdgeOne service. Since I had to manually clear the cache in the EdgeOne backend every time I updated an article, I wondered if I could write a plugin to achieve automatic refresh. Thus, this Tencent EdgeOne Cache Purger WordPress Plugin was born.

Explanation about cache plugin integration

Currently, the plugin integrates automatic purge functionality for four caching plugins: WP Super Cache, W3 Total Cache, WP Rocket, and LiteSpeed Cache. When you purge the cache in your caching plugin, the EdgeOne plugin will automatically purge the CDN cache.

However, Naibabiji's own website usesNginx FastCGI Cache. Only W3 Total Cache has been tested with a friend. If your caching plugin's purge does not automatically clear the CDN cache, please manually purge once in the EdgeOne cache plugin.
