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
