无法解析服务器名称或地址，为什么？

i using below code in my asp page of (www.test1.com)

我在我的asp页面(www.test1.com)中使用下面的代码

url= "http://www.test1.com/test.asp"
    dim http, pxml, http_response
    set http = server.CreateObject("MSXML2.ServerXMLHTTP.3.0")
    http.open "GET", url, 0
    http.setrequestheader "content-type", "text/xml; charset=utf-8"
    http.send ""

but i get error in my page like below

但我在我的页面中得到错误,如下所示

msxml3.dll error '80072ee7'

The server name or address could not be resolved

But i send requet to same server (http://www.test1.com) only the problem. but i send request to any other server like (http://www.test2.com) is working fine

但我发送requet到同一服务器(http://www.test1.com)只有问题。但我发送请求到任何其他服务器,如(http://www.test2.com)工作正常

why the problem in same server?

为什么同一台服务器出现问题?

It could be that the DNS for your web server doesn't have its own name listed (true, it happens!), so try using either 'localhost' or '127.0.0.1' instead.

可能是您的Web服务器的DNS没有列出自己的名称(true,它会发生!),因此请尝试使用“localhost”或“127.0.0.1”。

If you have PHP installed/enabled on this server, here's a quick way to check what server names it can resolve:

如果您在此服务器上安装/启用了PHP,则可以快速查看它可以解析的服务器名称:

<?php

function test() {
    $hostname = isset($_POST['hostname']) ? trim($_POST['hostname']) : false;

    if ($hostname) {
        echo "<h2>Hostname: ", htmlspecialchars($hostname), "</h2>\n";

        if ($addrs = gethostbynamel($hostname)) {
            echo "<div>\n";
            var_dump($addrs);
            echo "</div>\n";
        }
        else {
            echo "<p>No records found.</p>\n";
        }
    }
}

?>
<!DOCTYPE html>
<html>

<head>
<meta charset="utf-8">
<title>Test DNS record retrieval</title>
</head>

<body>
<h1>Test DNS record retrieval</h1>
<?php test(); ?>

<form action="<?php echo $_SERVER['SCRIPT_NAME']; ?>" method="post">
    <table>
        <tr>
            <th>host name:</th>
            <td><input type="text" tabindex="10" name="hostname" size="40" ></td>
        </tr>
        <tr>
            <td></td>
            <td><input type="submit" tabindex="99"></td>
        </tr>
    </table>
</form>

</body>
</html>
