因此,我正在遍历URL列表以检查它们是否已死或被重定向,然后记录结果。我也有一些例外,将重定向到godaddy.com或hugedomains.com之类的域标记为无效,基本上就是这样。
我的问题是,它参差不齐。例如,域
重定向到这些:
我尝试过滤掉“?reqp = 1&reqr =”,但有时会起作用。我可以运行该脚本,并且从十个无效/重定向的URL中运行,四个将被标记为无效,然后重新运行,并且将三个或五个标记为无效(并且结果不同,上一次可能标记为无效) ,我正在寻找更一致的结果。这是功能块:
function get_url_status($url) {
$cookie = realpath(dirname(__FILE__)) . "/cookie.txt";
file_put_contents($cookie, "");
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_NOBODY, 1);
if ($curl = curl_init()) {
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); // follow redirects
curl_setopt($ch, CURLOPT_AUTOREFERER, 1); // set referer on redirect
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie);
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (X11; Linux x86_64; rv:58.0) Gecko/20100101 Firefox/58.0');
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 20);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_exec($ch);
$http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
$final_url = curl_getinfo($ch, CURLINFO_EFFECTIVE_URL);
curl_close($ch);
if ((strpos($final_url, "hugedomains.com") !== FALSE) ||
(strpos($final_url, "namecheap.com") !== FALSE) ||
(strpos($final_url, "uniregistry.com") !== FALSE) ||
(strpos($final_url, "afternic.com") !== FALSE) ||
(strpos($final_url, "buydomains.com") !== FALSE) ||
(strpos($final_url, "/?nr=0") !== FALSE) ||
(strpos($final_url, "?reqp=1&reqr=") !== FALSE) ||
(strpos($final_url, "godaddy.com") !== FALSE)) {
return 'dead';
}
if (in_array($http_code, array('404', '403', '500', '0'))) {
return 'dead';
} elseif (($http_code == 200) || ($url == $final_url)) {
return 'ok';
} elseif ($http_code > 300 || $http_code < 400) {
return $final_url;
} else {
return '';
}
}
}
function quote_string($string) {
$string = str_replace('"', "'", $string);
$string = str_replace('&', '&', $string);
$string = str_replace(' ', ' ', $string);
$string = preg_replace('!\s+!', ' ', $string);
return '"' . trim($string) . '"';
}
有人有什么想法可以使其更可靠吗?
答案 0 :(得分:1)
也许比较原始URL和最终URL的域:
$orig_host = parse_url($url, PHP_URL_HOST);
$final_host = parse_url($final_url, PHP_URL_HOST);
$len = strlen($orig_host);
if (substr($final_host, 0 - $len) === $orig_host) {
echo "$final_host ends with $orig_host";
}
}
