使用YouTube API将视频上传到1个以上的频道

Question

使用YouTube API将视频上传到单个通道很简单。这就是我目前使用PHP客户库库的方式：

<?php
/**
 * This sample adds new tags to a YouTube video by:
 *
 * 1. Retrieving the video resource by calling the "youtube.videos.list" method
 *    and setting the "id" parameter
 * 2. Appending new tags to the video resource's snippet.tags[] list
 * 3. Updating the video resource by calling the youtube.videos.update method.

第一次运行脚本时，我被提示了一个窗口来验证请求，授予令牌并在60分钟内到期。

我想使用相同的脚本将视频上传到我拥有的不同频道。例如，如果我有3个不同的频道，我可以登录到不同的浏览器以对应用程序进行身份验证。我目前有10个以上的YouTube频道，我想在每隔几个小时后将内容上传到上传。

是否有一种方法可以从中央服务中管理所有这些渠道，以免每次添加新频道进行身份验证。还是有一种方法可以使用我的YouTube登录详细信息来验证YouTube API？

Answer 1

YouTube API与其他Google API略有不同。通常身份验证是基于用户帐户的。因此，如果我对您进行身份验证以访问我的Google日历，则可以访问所有我的Google日历。

YouTube API是基于用户频道的方式。您将必须在每个频道中对您的应用程序进行身份验证。然后确保您有一个刷新令牌。存储与频道名称相关的刷新令牌。然后，您的自动脚本将能够使用刷新令牌请求新的访问令牌并在需要时访问您的帐户。
这个问题是针对Analytics API的，但是该代码也应适用于YouTube，并进行一些小改动，以指向YouTube API。如何使用Google API客户端刷新令牌？
