我有这个脚本

<?php

//creating response array
$response = array();

if($_SERVER['REQUEST_METHOD']=='POST'){

//getting values
$teamName = $_POST['name'];
$memberCount = $_POST['member'];


//including the db operation file
require_once '../includes/DbOperation.php';

$db = new DbOperation();

//inserting values
if($db->createTeam($teamName,$memberCount)){
    $response['error']=false;
    $response['message']='Team added successfully';
}else{

    $response['error']=true;
    $response['message']='Could not add team';
}

}else{
$response['error']=true;
$response['message']='You are not authorized';
}
echo json_encode($response);

<?

当我在 Postman 中测试时，我会注意到这样的情况

<br/>
<b>Notice</b>: name in

<b>Notice</b>:  Undefined index: member in
<b>C:\xampp\htdocs\MyWebService\api\createteam.php</b> on line
<b>12</b>
<br />
{"error":true,"message":"Could not add team"}

未定义索引：成员

$memberCount = $_POST['member'];

您在预期的 POST 数据中缺少“成员”值

我建议在使用值之前检查它们是否存在。

if (!isset($_POST['member'])) {
    throw new Exception("missing expected value \"member\" in POST");
}
$memberCount = $_POST['member'];
