Question

我想将一个API与我的一个网站集成，这是我的高级管理人员给出的一项任务.API是关于搜索已经存在或不存在的域名。请帮助我解决这个问题请给我一个我可以推荐的例子。我的网站是PHP。

Answer 1

[编辑2] 正如@Poe在评论中提到的那样，gethostbyname可能是一个更好的解决方案，因为它适用于任何顶级域名，因为它执行DNS查询而不是一个whois查询，并且实现起来也更简单，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，域名可以注册，但它没有链接到任何计算机（例如，虽然这种情况非常罕见，但您可以获得www.example.com的解析，但不能获得example.com的解析）

[编辑] 我之前没有发布这个帖子，因为我在连接到端口43上的whois.internic.net时遇到了一些麻烦来执行whois查询（认为他们已经关闭了该服务）。无论如何，这是我刚刚编写的基于fsockopen的解决方案，我认为这比我在使用CGI Web脚本之前提供的解决方案要好得多，也简单得多。希望它有所帮助（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;
    }
}
?>

从内部网站，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=domain

您可以从脚本发送查询并将响应存储在DOMDocument对象上。查看：http://www.php.net/manual/en/domdocument.loadhtml.php

如果您使用此方法查找域并且该域不存在，您将获得字符串No match for domain。使用strpos

在回复中查找此内容

如果域名存在，您可以过滤回复以包含有关注册商等的信息。它将是回复的html标记<pre>的内容：
