Question

我正在尝试使用YouTube API将视频上传到YouTube。使用未更改的代码运行测试时，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.

at com.google.api.services.samples.youtube.cmdline.UploadVideo.main(UploadVideo.java:165)

我知道为什么以及如何解决它？

Answer 1

将getProgress()替换为getNumBytesUploaded()

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

它可以上传大型视频。

Answer 2

要使用getProgress()方法取得进展，API必须知道您尝试上传的文件的大小，您可以使用inputStreamContent.setLength(file.getSize())进行设置。

或者您可以按照建议使用getNumBytesUploaded()。

使用Java将视频上传到Youtube
