通过PHP验证Google Play链接

我想通过脚本检查应用程序的Google Play链接是否有效：

-有效 -无效的

但是每一个我买的或者免费的剧本都会给我404或者303的回应。可能有一些重定向

如何验证这样的链接。如果Google Play store中存在应用程序，我需要检查我的广告系统中的大约1000个链接

我将自己编写循环，从数据库中读取，等等。但请熟悉php的人帮助检查。我为此花了300美元，被两个人骗了，这就是“检查”链接。始终使用404或303。

尝试以下方法：

<?php
/**
 * Check google play app
 * 
 * @param string $url Url to check
 * 
 * @return boolean True if it exists, false otherwise
 * @throws \Exception On Curl error, an exception is thrown
 */
function checkGooglePlayApp($url)
{
    $curlOptions = array(
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_CUSTOMREQUEST  => 'GET',
        CURLOPT_URL => $url
    );

    $ch = curl_init();
    curl_setopt_array($ch, $curlOptions);
    $result = curl_exec($ch);
    $http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);

    if ($curl_error = curl_error($ch)) 
    {
        throw new \Exception($curl_error, Exception::CURL_ERROR);
    } 

    curl_close($ch);

    return $http_code == '200';
}

$url = 'https://play.google.com/store/apps/details?id=com.ketchapp.zigzaggameERRORERROR';
$result = checkGooglePlayApp($url);
var_dump($result); // Should return false

$url = 'https://play.google.com/store/apps/details?id=com.ketchapp.zigzaggame';
$result = checkGooglePlayApp($url);
var_dump($result); // Should return true

---

这可以通过get_headers函数轻松完成。例如：

不正确的URL

$file = 'https://play.google.com/store/apps/details?id=com.ketchapp.zigzaggamessdasd';
$file_headers = get_headers($file);
print_r($file_headers);

将返回：

如果文件确实存在，将返回：

因此，您可以创建如下脚本：

<?php
$files = ['https://play.google.com/store/apps/details?id=com.ketchapp.zigzaggame', 'https://play.google.com/store/apps/details?id=com.ketchapp.zigzaggamesadasd'];

foreach($files as $file)
{
   $headers = get_headers($file);

   if($headers[0] == 'HTTP/1.0 404 Not Found')
   {
      return false;
   }
   else
   {
      return true;
   }
}
?> 

您只需执行以下操作

    function checkGooglePlayApp($url)
    {
            $headers = get_headers($url);
            return $headers[0] == 'HTTP/1.0 404 Not Found';
    }
    $inValid = checkGooglePlayApp("https://play.google.com/store/apps/details?id=com.ketchapp.zigzaggame");

    if(!$inVald)
    {
      echo "URL Valid";
    }
    else{
       echo "URL Invalid";
    }

看起来您必须使用第三方API来完成此操作。一个快速的谷歌展示了android市场的一些选择。
