我创建了一个 html 表单，并且正在使用 php 脚本检索用户输入。

我的表格要求选项 1 和选项 2。

当用户按下提交按钮时，php 脚本被调用，这些数据存储在两个变量中：$option1 和 $option2。

这是我的 php 脚本：

<?php

 if (isset($_POST['option1']) AND isset($_POST['option2']))
 {
 $option1 = htmlentities($_POST['option1']);
 $option2 = htmlentities($_POST['option2']);

 if (empty($option1))
 {
  echo ("Saisissez votre pseudo");
  exit();
 }
 if (empty($option2))
 {
  echo ("Le titre ne peut être vide");
  exit();
 }
}

//Here will be the HTTP POST request 

?>

我想要做的是将 HTTP POST 请求发送到 Web 服务并将这些数据作为参数传递。

这是调用 Orchestrator Web 服务的 HTTP POST 请求全局语法：

尝试执行此操作时遇到 HTP 500 错误：

    exit();
   }

   echo $vlan_id;
   echo ' was correctly created with the name ';
   echo $vlan_name;

    $result = ''; 
    while(!feof($fp)) {
        // receive the results of the request
        $result .= fgets($fp, 128);
    }

    return array(
