下面分享一下部署方法。

//提交评论刷新当前文章CDN缓存

function post_data($url, $data, $type = "POST") {

//生成tokens

/**
* 提交刷新
* @param $data
* @return array
*/
function refresh($data) {
global $cdn_provider;
$token = get_verycdn_token();
if(!$token) {
return array(
'code' => 0,
'message' => 'unable to get token'
);
}
//刷新类型 file 文件 dir 目录
$type = isset($data['type']) && !empty($data['type']) ? trim($data['type']) : '';
//刷新url
$urls = isset($data['urls']) && !empty($data['urls']) ? $data['urls'] : '';
//url分隔符,多个url使用该符号分隔,默认,
$partition = isset($data['partition']) && !empty($data['partition']) ? trim($data['partition']) : ',';
if(empty($type) || empty($urls)) {
return array(
'code' => 0,
'message' => 'type and urls are required',
);
}
$url = $cdn_provider["verycdn"]["push"];
$send_data = array(
'token' => $token,
'type' => $type,
'urls' => $urls,
'partition' => $partition
);
$return = post_data($url, $send_data);
return $return;
}
将以上代码粘贴到WordPress主题functions.php中,然后将 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,如果需要部署这个功能,需要联系客服,然后告知需要使用这个刷新CDN缓存的API,然后提供以下用户名给他就好了。而且代码中的lockstream的值可能需要VC客服提供,如果发现上述代码无法成功,请自行咨询VC客服。
部署好了之后,可以去更新文章或提交评论,然后登陆VeryCloud云分发后台,即可看到提交记录
