谷歌ping失败 - cURL


Google ping failing - cURL

当我更新站点地图时,我试图ping谷歌,但总是得到响应"0"

这是我正在尝试的:

$sitemapUrl = urlencode("http://testsite.com/Sitemap.xml");
// cUrl handler to ping the Sitemap submission URLs for Search Engines…
function myCurl($url) {
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_exec($ch);
    $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    curl_close($ch);
    return $httpCode;
}
//Google
$url = "http: //www.google.com/webmasters/tools/ping?sitemap=".$sitemapUrl;
$returnCode = myCurl($url);
echo = "<p> Google Sitemaps has been pinged (return code: $returnCode). </p>";

其中返回:

Google Sitemaps has been pinged (return code: 0). 
您需要

添加这些参数,因为Google HTTPS/SSL协议上运行。

  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
  curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
