我使用的是CodeIgniter+Zend库。我想让用户上传视频到我的网站，然后我会上传到我的YouTube频道。这是我第一次接触YouTube API。有人能给我指正确的方向吗？
我这样看对吗：http://code.google.com/apis/youtube/2.0/developers_guide_protocol.html#Direct_uploading?有没有人有一段代码可以展示如何通过PHP进行上传？
试试它的工作

由于Zend的大小和复杂性，我不建议将其与CI一起使用。我专门为CodeIgniter开发了一个库https://github.com/jimdoescode/CodeIgniter-YouTube-API-Library
该库提供了几种不同的上传到YouTube的选项。你可以直接上传存储在服务器上的视频到youtube。还有一个选项可以使用表单将视频从客户端上传到youtube。看看它，如果你有任何问题，请告诉我。
文档包含Zend Gdata的此方法以及其他方法：上传视频
