我想将一个API与我的一个网站集成在一起，这是我的前辈给我的任务。API是关于搜索域名是否已存在。。请在这个话题上帮我请给我一个我可以参考的例子。我的网站是用PHP编写的。
[EDIT 2]正如@Poe在评论中提到的，gethostbyname可能是一个更好的解决方案，因为它适用于任何顶级域，因为它执行DNS查询而不是whois查询，而且实现起来更简单，可能更快：
<?php
$ip = gethostbyname('example.com');
if (strstr($ip,"example.com")){
echo "No match for domain example.com<br />'n";
} else {
echo "Domain found. Query output: <br />'n".$ip;
}
?>
无论如何，一个域可以注册，但它没有链接到任何计算机（例如，尽管这很少见，但你可能会得到www.example.com但不是example.com的解析）
[EDIT]我以前没有发布这个消息，因为我在连接到端口43上的whois.internic.net执行whois查询时遇到了一些问题（我认为他们已经永远关闭了服务）。无论如何，这是我刚刚编写的一个基于fsockopen的解决方案，我认为它比我在使用他们的CGI web脚本之前给出的解决方案要好得多，也简单得多。希望它能有所帮助（用法：myqueryscript.php？domain=domainiwanttocheck.com）：
<?php
$fp = fsockopen("199.7.58.74", 43, $errno, $errstr, 30);
if (!$fp) {
echo "$errstr ($errno)<br />'n";
} else {
$query = $_GET['domain']."'r'n";
$answer= '';
fwrite($fp, $query);
while (!feof($fp)) {
$answer .= fgets($fp, 128)."<br />";
}
fclose($fp);
if (strstr($answer,"No match for")){
echo "No match for domain ".$_GET['domain']."<br />'n";
} else {
echo "Domain found. Query output: <br />'n".$answer;
}
}
?>
从国际网站，这是实现whois查询的html代码：
<form method="get" action="http://reports.internic.net/cgi/whois" name="my_form">
<input type="text" size="30" name="whois_nic" maxlength="80">
<br>
<input type="radio" name="type" value="domain" checked>
Domain<font size="-1"> (ex. internic.net)
<br>
<input type="radio" name="type" value="registrar">
Registrar<font size="-1"> (ex. ABC Registrar, Inc.)
<br>
<input type="radio" name="type" value="nameserver">
Nameserver (ex. NS.EXAMPLE.COM or 192.16.0.192)<br>
<br>
<input type="submit" value="Submit">
</form>
这意味着您可以发送这样的whois查询：http://reports.internic.net/cgi/whois?whois_nic=domainiwanttocheck.com&type=域
您可以从脚本中发送查询，并将响应存储在DOMDocument对象上。退房时间：http://www.php.net/manual/en/domdocument.loadhtml.php
如果使用此方法查找域，但该域不存在，则会得到字符串No match for domain。使用strpos 在响应中查找此信息
如果域存在，您可以过滤响应以包括有关注册商的信息等。它将是响应的html标签<pre>的内容：

另外，看看这个相关的问题：谁提供WHOIS API？
<?php
if(isset($_GET['domain'])){
$domain = $_GET['domain'];
} else {
$domain = "";
}
$api_key = "api_key";
//domain also you can use this api http://api.neoistone.com/domain-check/?apiKey=&domainName=google.com
//if need api key contact us https://www.neoistone.com/contact-us/
//domain also your user the api https://domain-availability.whoisxmlapi.com/api/v1/?apiKey=&domainName=google.com
//if need api key contact us browser https://domain-availability.whoisxmlapi.com
$api = "https://domain-availability.whoisxmlapi.com/api/v1";
$api .= '?apiKey='.urlencode($api_key);
$api .= "&domainName=".urlencode($domain);
$response = array();
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => $api,CURLOPT_RETURNTRANSFER => true,CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,CURLOPT_TIMEOUT => 30,CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "GET",CURLOPT_HTTPHEADER => array("cache-control: no-cache","postman-token: 22890b81-68a3-c75c-7dc5-1d1e6e9d1cf2"),));
$ch_ap = json_decode(curl_exec($curl),TRUE);
if (isset($ch_ap['messages'])) {
$response['status'] = "error";
$response['message'] = $ch_ap['messages'];
$response['code'] = $ch_ap['code'];
} else {
$curl_response = $ch_ap['DomainInfo'];
if ($curl_response['domainAvailability'] == "UNAVAILABLE") {
$response['status'] = "sussfuly";
$response['meassage'] = 'Domain is '.$domain.' unavailable ';
$response['code'] = 200;
} elseif ($curl_response['domainAvailability'] == "AVAILABLE") {
$response['status'] = "sussfuly";
$response['meassage'] = 'Domain is '.$domain.' available ';
$response['code'] = 200;
} else {
$response = $curl_response;
}
}
print_r($response);
curl_close($curl);
?>
获取域名和tld
<?php
$host = 'https://compute-1.hyd.in.securedatacenter.host';
preg_match("/[^'.'/]+'.[^'.'/]+$/", $host, $matches);
$data = explode('.',$matches['0']);
//print_r($data);
echo 'Your domain name is :- '.$data['0'].'<br>';
echo 'Your tld is :- '.$data['1'];
?>
