java - 将大文件插入 Google 驱动器时出现 IOException "insufficient data written"

Question

我正在尝试使用 google-api-services-drive 版本 v2-rev93-1.16.0-rc 将大文件插入 Google 的驱动器 我已将 setChunkSize() 设置为最小值，以便更频繁地通知我自己的 ProgressListener。以下代码用于插入文件:

File body = new File();
body.setTitle(filetobeuploaded.getName());
body.setMimeType("application/zip");
body.setFileSize(filetobeuploaded.length());

InputStreamContent mediaContent =
        new InputStreamContent("application/zip",
        new BufferedInputStream(new FileInputStream(filetobeuploaded)));
mediaContent.setLength(filetobeuploaded.length());

Insert insert = drive.files().insert(body, mediaContent);
MediaHttpUploader uploader = insert.getMediaHttpUploader();
uploader.setChunkSize(MediaHttpUploader.MINIMUM_CHUNK_SIZE);
uploader.setProgressListener(new CustomProgressListener(filetobeuploaded));
insert.execute();

“一段时间”后(有时 200 MB 有时 300 MB)我得到了 IOException :

Exception in thread "main" java.io.IOException: insufficient data written
at sun.net.www.protocol.http.HttpURLConnection$StreamingOutputStream.close(HttpURLConnection.java:3213)
at com.google.api.client.http.javanet.NetHttpRequest.execute(NetHttpRequest.java:81)

at com.google.api.client.googleapis.services.AbstractGoogleClientRequest.execute(AbstractGoogleClientRequest.java:460)

有什么想法可以让这段代码正常工作吗？

由于时间限制，您将无法从前端运行它。唯一可靠的方法(但很痛苦)是使用可恢复上传从后端执行此操作，因为后端/任务队列也可能在处理 block 时关闭。
