如何反序列化由 GSON 序列化的 PHP 中的数据

Question

我正在使用PHP 开发的 api 开发 android 应用程序。我正在尝试将一个对象发送到 api，因此我使用Gson 库对其进行序列化，并尝试使用Unserialize() 函数在PHP 代码中反序列化。但是，它给出的错误为(!)Notice: unserialize(): Error at offset 0 of 468 bytes in C:\wamp64\www\digiclass\admin\api\upload_pending_results.php on line 5，最后给出的json响应为{"error":false,"data":false}这是我的PHP代码：

<?php
//an array to display response
$response = array();
$serObject = $_POST['serObject'];
$response['error'] = false;
$response['data'] = unserialize($serObject);
echo json_encode($response);
?>

目前，我没有对数据执行任何操作，只想查看数据是否正确反序列化。我试过看序列化的对象，转换如下。

我不确定转换是否正确或错误可能是什么。有人可以帮忙吗？

你得到的值是一个 URL 编码的 JSON 字符串，所以首先解码它...

$serObject = urldecode($serObject);

然后将其解码为 JSON...

$response['data'] = json_decode($serObject, true);
