php - "error":true,"message":"required parameters are not available" while check api call using postman

问题描述

我正在学习如何使用 volley 将 android 应用程序与 php 管理面板连接起来，为此我使用了Javatpoint的教程，但是当他们告诉我在Postman web中创建和检查 apicall 时，我制作了两个文件，我收到了这个错误：

"error":true,"message":"所需参数不可用"

我也附上了截图

这是我要从中获取数据的表的结构。

谁能帮我解决这个错误，我真的不知道如何解决它。

<?php   
  require_once 'connection.php';  
  $response = array();  
  if(isset($_GET['apicall'])){  
  switch($_GET['apicall']){  
  case 'signup':  
    if(isTheseParametersAvailable(array('username','email','password',))){  
    $username = $_POST['username'];   
    $email = $_POST['email'];   
    $password = md5($_POST['password']);  
   
    $stmt = $conn->prepare("SELECT user_id FROM ci_users WHERE username = ? OR email = ?");  
    $stmt->bind_param("ss", $username, $email);  
    $stmt->execute();  
    $stmt->store_result();  
   
    if($stmt->num_rows > 0){  
        $response['error'] = true;  
        $response['message'] = 'User already registered';  
        $stmt->close();  
    }  
    else{  
        $stmt = $conn->prepare("INSERT INTO ci_users (username, email, password,) VALUES (?, ?, ?, ?)");
