YouTube PHP API：会话状态与空字符串(10)不匹配"1494600193"

Question

我创建了一个YouTube API，我将用它来通过PHP上传我自己的视频。当我访问 URL 时，它似乎一直在工作，直到我尝试授权它，此时我会收到消息：

NULL string(10) "1494600193" The session state did not match.

我正确设置了我的授权重定向 URI（http://example.com/uploadvideo.php ），并通过 composer.json 安装了库。我还启用了几乎所有功能。

我不知道为什么这对我不起作用。有什么想法吗？

我正在尝试 Google 的示例代码 uploadvideo.php ：

<?php
// Call set_include_path() as needed to point to your client library.
require_once 'vendor/autoload.php';
session_start();
/*

尝试查看删除网站cookie时问题是否消失。如果是这样，您：

• 查看以刷新会话或令牌。
• 另一种选择可能是在处理后清理饼干。最后一个确实要求您在每次上传时重新进行身份验证。
