我最近从Ambient Weather购买了WS-1400-IP气象站，该气象站连接到Weather Underground。我试图在IP链接设备的HTML上进行DOM查询。这是我的代码：
（我知道它非常粗糙的代码，这只是一个初步的事情。）
<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);
$filename = "http://10.175.3.28/bscsetting.htm";
$html = file_get_contents($filename);
echo "<input type=text value='{$html}'></input>";
$dom = new DOMDocument();
@$dom->loadHTML($html);
$x = new DOMXPath($dom);
$data = array();
foreach($x->query("//input") as $node)
{
$data[][$node->getAttribute("name")] = $node->getAttribute("value");
}
echo json_encode($data, JSON_PRETTY_PRINT);
当我回应我从设备获取的HTML时，这就是我所看到的：
<input type=text value='ction: Keep-Alive
Content-type: text/html
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=big5">
<meta http-equiv="refresh" content="0;URL=./bscsetting.htm">
<title></title>
<body leftmargin="80" topmargin="80" marginwidth="80" marginheight="0" bgcolor="#333">
<font size="+3"><strong><p align="center"></p></strong></font>
</body>
</html>
'></input>[
]
以下是我应该看到的内容（因为这是我在使用常规浏览器时看到的内容）：

如何通过元刷新？有什么想法吗？
编辑：尝试卷曲后，它按预期工作..为什么会有所作为？

他们有一个API，并通过RESTful协议使用JSON。您需要在请求中发送api密钥，以使用服务器的api密钥对服务器进行身份验证。全部免费，然后可以指定您要查找的过去和现在的数据。然后，您可以在网页上显示或保存到数据库
