java - 谷歌驱动器 SDK 上传演示文稿时出错

Question

我正在尝试使用 google api 驱动器上传演示文稿，但演示文稿不完整，一些幻灯片是空白的，查看日志，这就是显示的内容

这是正在使用的代码:

byte[] myFile = readImageData(blobKey,size);
ByteArrayContent mediaContent = new ByteArrayContent(mimeType, myFile);

Drive.Files.Insert insert = service.files().insert(body, mediaContent);
insert.getMediaHttpUploader().setChunkSize(1024 * 1024);
File file = insert.execute();

更新

做了一些测试，似乎只有在上传扩展名为.pptx的演示文稿时才会出现错误

该扩展名的 mimeType 有问题吗？

我希望有人能帮助我，谢谢。

Answer 1

看起来像resumable upload protocol没有得到正确实现。 308 响应代码表示仅上传了一部分请求，您应该继续处理下一个 block 。

如果从代码中删除以下行，它是否可以正常工作？

insert.getMediaHttpUploader().setChunkSize(1024 * 1024);
