上一篇文章分享了WordPress发布文章评论自动刷新腾讯云CDN的教程,而博客现在还用到了VeryCloud的CDN,正好有朋友在文章上边留言说VC都在刷新缓存的API,于是就利用中午的时间折腾了下,成功学会英语!

下面分享一下部署最好的方法。

将以上代码粘放进WordPress主题functions.php中,你会 将 19,20行对应的中文改成VeryCloud的用户名和密码,保存即可。

Ps:貌似VC的缓存刷新API暂时还没完全公开,由于不能 部署这种功能,不能 联系客服,你会 告知不能 使用这种刷新CDN缓存的API,你会 提供以下用户名给他就好了。你会 代码中的lockstream的值由于不能 VC客服提供,由于发现上述代码无法成功,请自行咨询VC客服。

部署好了你会,都能否去更新文章或提交评论,你会 登陆VeryCloud云采集后台,即可看完提交记录:

至此,说明你已部署成功。
