Question

我想通过关闭翻转开关的帮助从网页控制一个led，我在网上找到它。我用一个翻转开关制作了一个简单的网页，检查GPIO x是高还是低，并将其调整到翻转开关，但我没有任何结果，有什么帮助吗？

我的php脚本：

<?php
$read_gpio13 = shell_exec("/usr/local/bin/gpio read 13");
$red_checked = ($read_gpio13 == 1) ? "checked=\"\"" : "";
?>
<html>
<head>
  <title></title>    
  <link rel="stylesheet" type="text/css"  href="Flip2.css">
   </head>
    <script>
     $(document).ready(function() {
         $("#myonoffswitch").change(function() {
         var isChecked = $("#myonoffswitch").is(":checked") ? 1:0; 
         if (isChecked){
         $.ajax({
                 url: 'red.php',
                 type: 'POST',
         });
           }
          else {
          $.ajax({
                 url: 'redoff.php',
                 type: 'POST',
         });
           }
       });
     });
  </script> 
 <form> 
 <div class="onoffswitch">
 <input type="checkbox" name="onoffswitch" class="onoffswitch-checkbox" 
 id="myonoffswitch" <?php echo $red_checked; ?>>
 <label class="onoffswitch-label" for="myonoffswitch">
    <span class="onoffswitch-inner"></span>
    <span class="onoffswitch-switch"></span>
</label>
</div>
</form>
</html>

red.php：

<?php
shell_exec("/usr/local/bin/gpio -g mode 13 out");
shell_exec("/usr/local/bin/gpio -g write 13 1");
?>

redoff.php：

<?php
// set to output
shell_exec("/usr/local/bin/gpio -g write 13 0");
?>
