【问题描述】：
我正在设置一个（无头）网络服务器，让人们可以制作自己的自定义延时电影。
有几个人想将他们制作的延时视频上传到 YouTube。 与其将视频下载到那个人的笔记本电脑上， 然后那个人手动将其上传到 YouTube， 有没有办法可以在我的网络服务器上编写一些软件来获取我的网络服务器上的视频文件并将其直接上传到该用户在 YouTube 上的帐户？
有人告诉我，向我的用户询问他们的 YouTube 句柄和密码是错误的做法，我应该使用带有 Oauth 的 YouTube V3 API。
我尝试了以下所列的技术 "I want to upload a video from my web page to youtube by using javascript youtube API", 这似乎“有效”，但每次我都必须将视频下载到那个人的笔记本电脑，然后从笔记本电脑上传到 YouTube。有没有办法调整该系统以直接从我的服务器上传到 YouTube？
我发现了一些 python 代码（在我设置了我的 client_secrets.json 之后），我可以将视频直接从我的服务器直接上传到某人的 YouTube 帐户该人进行了 Oauth 身份验证。 但是，当某个新人第一次尝试将视频上传到我的服务器以前从未处理过的某个新 YouTube 帐户时，它要么 (a) 在我的服务器上打开一个网络浏览器，然后如果我 VNC 到服务器并在该网络浏览器中输入 YouTube 句柄和密码，它就会得到身份验证——但我不想为每个用户都这样做。 (b) 使用“--noauth_local_webserver”选项，在命令行中输出一个 URL 并等待。然后，如果我手动复制该 URL 并将其粘贴到 Web 浏览器中，登录到 YouTube，将令牌复制并粘贴回仍在等待命令行输入的应用程序中，该人将获得身份验证。但我不想对每个用户都这样做。我想如果我可以在我的 cgi-bin 脚本中捕获该 URL 并将其粘贴到网页中，然后以某种方式获取身份验证响应并将其塞回该程序中，那将是可以的，但是如何？我什至没有在这段代码中看到 print 语句或 raw_input 语句。
