我正在运行 AngularJS app .
之前在本地跑过，可以发到本地服务器。
现在我在实时服务器上尝试它，但出现以下错误:
Unable to create Reservation.
此错误是从 create.php 页面发布的，每当它无法发布到服务器时。
有人知道我的代码有什么问题吗？
创建.php页面

它似乎没有设置属性值。
// set product property values
$reservation->name = $data->name;
$reservation->eMail = $data->eMail;
$reservation->phoneNumber = $data->phoneNumber;
$reservation->colorScooter = $data->colorScooter;
$reservation->amountScooters = $data->amountScooters;
$reservation->inputDate = $data->inputDate;
$reservation->returnDate = $data->returnDate;
$reservation->category_id = $data->category_id;
$reservation->created = date('Y-m-d H:i:s');
我可以在打开 create.php live vs local 时看到这个

运行 createproduct() 它会将它post 到 create.php
我用 google chrome 的检查器网络选项卡检查了它。
{name: "test", email: "test", phone: "test", amount: "test", description: "test", pickup: "test",…}
amount
:
"test"
back
:
"test"
description
:
"test"
email
:

name

phone
:

pickup

它还返回代码:200
根据这个 link意思是:
200 好 此响应码表示请求成功。
201 创建 这表示请求成功并创建了资源。它用于确认 PUT 或 POST 请求是否成功。
它似乎没有创建新资源，也没有发布任何内容。
最佳答案
为什么要使用 php://input？您不使用 $_POST 访问发布的数据是否有原因？如果 POST 请求命中 php，则创建全局关联数组 $_POST。每个索引都将匹配您表单中的一个名称属性并包含其值。
显示的错误可能来自这种方法，因为 php://input 可以是任何东西，所以 $data 可以。如果是这种情况，您尝试从实际上不是对象的对象中分配值($reservation->name = $data->name;)。
// get posted data
$data = json_decode(file_get_contents("php://input"));
// set product property values
$reservation->name = $data->name;
$reservation->eMail = $data->eMail;
$reservation->phoneNumber = $data->phoneNumber;
$reservation->colorScooter = $data->colorScooter;
$reservation->amountScooters = $data->amountScooters;
$reservation->inputDate = $data->inputDate;
$reservation->returnDate = $data->returnDate;
$reservation->category_id = $data->category_id;
$reservation->created = date('Y-m-d H:i:s');
阐明 $data 的数据类型并确保它无论如何保持不变。 (尝试使用 var_dump 而不是 echo 或 print_r，提供额外的信息)
