谷歌網站Ping成功

Question

我有一個PHP腳本，創建一個XML網站地圖。最後，我使用

shell_exec('ping -c1 www.google.com/webmasters/tools/ping?sitemap=sitemapurl'); 

將更新後的站點地圖提交給Google網站站長工具。

閱讀Google文檔後，我不確定每次是否需要這樣做。通過手動輸入代碼中的鏈接，可以從google獲得成功頁面，但使用ping命令我不會收到確認。我還想知道是否有任何方法來檢查命令是否真正起作用。

Answer 1

這樣以來shell_exec()，exec()，passthru()等命令是由許多託管封鎖，你應該使用curl和檢查的200

響應代碼你也可以使用fsockopen如果捲曲不可用。我將檢查代碼段並在找到答案時更新答案。

UPDATE：

發現了它。我知道我在某個地方使用過它。有趣的指令：它在我的Sitemap類中xD 你可以在github上找到它：https://github.com/func0der/Sitemap。它位於Sitemap \ SitemapOrg類中。 還有一個實施捲曲調用的例子。

無論哪種方式，這裏是獨立實施的代碼。

/** 
* Call url with fsockopen and return the response status. 
* 
* @param string $url 
* The url to call. 
* 
* @return mixed(boolean|int) 
* The http status code of the response. FALSE if something went wrong. 
*/ 
function _callWithFSockOpen($url) { 
    $result = FALSE; 

    // Parse url. 
    $url = parse_url($url); 
    // Append query to path. 
    $url['path'] .= '?'.$url['query']; 

    // Setup fsockopen. 
    $port = 80; 
    $timeout = 10; 
    $fso = fsockopen($url['host'], $port, $errno, $errstr, $timeout); 

    // Proceed if connection was successfully opened. 
    if ($fso) { 
     // Create headers. 
     $headers = 'GET ' . $url['path'] . 'HTTP/1.0' . "\r\n"; 
     $headers .= 'Host: ' . $url['host'] . "\r\n"; 
     $headers .= 'Connection: closed' . "\r\n"; 
     $headers .= "\r\n"; 

     // Write headers to socket. 
     fwrite($fso, $headers); 

     // Set timeout for stream read/write. 
     stream_set_timeout($fso, $timeout); 

     // Use a loop in case something unexpected happens. 
     // I do not know what, but that why it is unexpected.   
     while (!feof($fso)){ 
      // 128 bytes is getting the header with the http response code in it.    
      $buffer = fread($fso, 128); 

      // Filter only the http status line (first line) and break loop on success. 
      if(!empty($buffer) && ($buffer = substr($buffer, 0, strpos($buffer, "\r\n")))){ 
       break; 
      } 
     } 

     // Match status. 
     preg_match('/^HTTP.+\s(\d{3})/', $buffer, $match); 
     // Extract status. 
     list(, $status) = $match; 

     $result = $status; 
    } 
    else { 
     // @XXX: Throw exception here?? 
    } 

    return (int) $result; 
} 

如果你們發現這個代碼的任何傷害或改進，不要猶豫，在GitHub上開闢票/拉請求，請。 ;）

這裏是一個腳本來自動提交你的網站地圖，谷歌，冰/ MSN，問：

/* 
* Sitemap Submitter 
* Use this script to submit your site maps automatically to Google, Bing.MSN and Ask 
* Trigger this script on a schedule of your choosing or after your site map gets updated. 
*/ 

//Set this to be your site map URL 
$sitemapUrl = "http://www.example.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 
$url = "http://www.google.com/webmasters/sitemaps/ping?sitemap=".$sitemapUrl; 
$returnCode = myCurl($url); 
echo "<p>Google Sitemaps has been pinged (return code: $returnCode).</p>"; 

//Bing/MSN 
$url = "http://www.bing.com/ping?siteMap=".$sitemapUrl; 
$returnCode = myCurl($url); 
echo "<p>Bing/MSN Sitemaps has been pinged (return code: $returnCode).</p>"; 

//ASK 
$url = "http://submissions.ask.com/ping?sitemap=".$sitemapUrl; 
$returnCode = myCurl($url); 
echo "<p>ASK.com Sitemaps has been pinged (return code: $returnCode).</p>"; 

還可以，如果提交失敗，給自己發送一封電子郵件：

function return_code_check($pingedURL, $returnedCode) { 

    $to = "webmaster@yoursite.com"; 
    $subject = "Sitemap ping fail: ".$pingedURL; 
    $message = "Error code ".$returnedCode.". Go check it out!"; 
    $headers = "From: hello@yoursite.com"; 

    if($returnedCode != "200") { 
     mail($to, $subject, $message, $headers); 
    } 
} 

希望幫助

簡單的解決方案：file_get_contents("https://www.google.com/webmasters/tools/ping?sitemap={$sitemap}");

這將適用於每個主要託管服務提供商。如果你想選購的錯誤報告，這裏是一個開始：

$data = file_get_contents("https://www.google.com/webmasters/tools/ping?sitemap={$sitemap}"); 
$status = (strpos($data,"Sitemap Notification Received") !== false) ? "OK" : "ERROR"; 
echo "Submitting Google Sitemap: {$status}\n"; 

至於如何你應該經常這樣做，只要你的網站可以處理來自谷歌的機器人額外的流量，而不會減慢，你應該這樣做，每次已經做出了改變。
