Question

我有一个noob问题 - 我创建了一个非常简单的HTML页面，当按下按钮时，通过我的网络将一串串行数据发送到以太网到串行转换器。它控制音频矩阵开关（通过其串行端口）。网页工作，它切换音频矩阵，但在我点击一个按钮后，浏览器无限期地等待响应。我可以点击其他按钮并仍然进行切换，但它总是在等待响应。如何从该远程设备获取响应并在网页上显示（或对其进行操作），并使页面无限期等待？这是将此数据字符串发送到远程IP的正确方法，还是有更好的方法？这是代码：

Answer 1

1）使用PHP

设置Apache Web服务器

2）下载PHP Telnet脚本（或任何其他PHP的Telnet库）

3）修改字符串

    if ($this->fp=fsockopen($ip,23)) {

到

    if ($this->fp=fsockopen($ip,100)) {

（根据我的理解，您的设备是否响应端口100？）

4）用这样的东西制作PHP脚本（用你的凭证替换username和password）：的 proxy.php

<?php require_once "PHPTelnet.php"; $telnet = new PHPTelnet(); $command = $_GET['command']; $result = $telnet->Connect('192.168.5.30:100','username','password'); if ($result == 0) { $telnet->DoCommand($command, $result); echo $result; $telnet->Disconnect(); } ?>

5）使HTML页面与此类似（这是非常基本的，只是为了让您了解并用您的网络服务器的IP替换yourhost）：

<html> <body> <form action="http://yourhost/proxy.php" method="GET"> Enter command <input type="text" name="command"> <input type="Submit"> </form> <form action="http://yourhost/proxy.php" method="GET"> <input type="hidden" value="CL1I3O1T" id="Backyard Apple TV" name="command" /> <input type="Submit" value="Apple TV"> </form> </body> </html>

复制HTML文件的最后一部分以添加其他命令。将实际命令放在value hidden输入中，并在value输入的submit标记。

Answer 2

我知道这篇文章没有标记PHP，但我终于用PHP套接字解决了这个问题。此网页将响应按下网页按钮，打开到远程IP的套接字，发送一串数据，最后关闭套接字。正如我之前提到的，远程设备是以太网到串行转换器，它连接到音频切换器。我现在可以使用PHP网页控制这个以太网连接/串行控制的音频切换器。代码非常简单，但是语法正确很难。感谢所有帮助过的人！我希望这有助于其他人......以下是代码：

<?php

$input=$_POST['input'];
$sock = fsockopen('192.168.5.30:100', NULL, $errno, $errstr);
fwrite($sock, $input);
echo fread($sock, 4096)."\n";
fclose($sock);
?>
