php curl调用蓝汛刷新CDN缓存接口

直接贴代码

　　　　$urls = array(
            "",
            "",
            ""
        );

        $data =array(
            "username" => $this->cdnUserName,
            "password" => $this->cdnPwd
        ) ;

        $data['task'] = json_encode(
            array(
                'urls' => $urls
            )
        );

        $data = http_build_query($data);
        $url = "https://r.chinacache.com/content/refresh";
        $curl = curl_init();
        curl_setopt($curl, CURLOPT_POST, 1);
        curl_setopt($curl, CURLOPT_URL, $url);
        curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
        curl_setopt($curl, CURLOPT_TIMEOUT, 30);
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
        $html = curl_exec($curl);
        if (curl_errno($curl)) {
            //to do...
        } else {
            //to do...
        }
        curl_close($curl);

期间curl报了：Couldn't resolve host 'r.chinacache.com'错误信息，用nslookup查看

# nslookup r.chinacache.com
;; connection timed out; trying next origin
;; connection timed out; no servers could be reached

解决方式为

# vi /etc/resolv.conf

nameserver 8.8.8.8

保存退出

再用nslookup查看

# nslookup r.chinacache.com
Server:        8.8.8.8
Address:    8.8.8.8#53
