我有 2 个工作网页,我正试图将它们合并为一个。第一个是 PHP,按一下按钮,它会打开一个套接字并将一串数据发送到我网络上的设备。
第二个网页有类似的功能,但不是 PHP。此页面有链接到 CGI 脚本的按钮,这些按钮被调用并将数据发送到串行端口。
我想使用 PHP 网页,其中一些按钮的功能与现在一样(打开 PHP 套接字并将数据发送到 IP 地址),但也有一些按钮可以在不使用 CGI 脚本的情况下将数据发送到串行端口或爪哇。
这是有效的基本 PHP 页面:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<?php
// Checks to see if button pressed
if(isset($_POST['input'])) {
// Assigns value of button press to $input variable
$input=$_POST['input'];
//echo "$input<br />";
// Open the socket to the IP address
$sock = fsockopen('192.168.5.30:4660', NULL, $errno, $errstr);
// Send the value of the button press to the IP address
fwrite($sock, $input);
// Display the response from the socket on the webpage
echo fread($sock, 4096)."\n";
// Close the socket
fclose($sock); }
// If input is not set, then wait
else {
//input is not set, do something about it, raise an error, throw an exception, or whatever
}
?>

<br />
<br />
</form>
</body>
</html>
这是我正在运行的基本 CGI 脚本:
#!/bin/sh -ax
#Send out the serial command in Hex code
echo -e "OF1/r" > /dev/ttyACM0
#Redirect the browser back to the index page
echo "Content-type: text/html"
echo ""
echo "<html><head><title>Audio Control</title>"
echo "</head><body>"
echo "<script type="text/javascript"><!--"
echo "setTimeout('Redirect()',0);"
echo " function Redirect(){ location.href = '../index.html';}"
PHP echo " --></script></body></html>"
我有兴趣集成到 PHP 网页按钮中的功能是 echo -e "OF1/r" > /dev/ttyACM0。该命令向串口发送“OF1/r”。
谢谢!
