使用Java将视频上传到Youtube

Question

我正在尝试使用YouTube API将视频上传到YouTube。使用不变的代码运行测试时抛出以下异常：

Exception in thread "main" java.lang.IllegalArgumentException: Cannot call getProgress() if the specified AbstractInputStreamContent has no content length. Use getNumBytesUploaded() to denote progress instead.

任何想法为什么以及如何修复它？

Answer 1

更换getProgress()到getNumBytesUploaded()

System.out.println("Upload percentage: " + uploader.getNumBytesUploaded()); 

它工作的，你可以上传大型视频。
