我正在使用我的App Engine允許應用上傳文件。 該文件在HTTP POST中收到，我試圖將其存儲在Google Storage中。無法通過我的Google App Engine Servlet（Java）在Google雲端存儲中存儲對象
我的服務器代碼;
GcsFileOptions instance = GcsFileOptions.getDefaultInstance();
GcsFilename fileName = new GcsFilename("my-bucket", "file.dat");
GcsOutputChannel outputChannel;
log.info("Saving " + fileName + " to " + instance);
outputChannel = gcsService.createOrReplace(fileName, instance);
copy(req.getInputStream(), Channels.newOutputStream(outputChannel));
中間產量的日誌條目;
com.my.app.Servlet: Saving GcsFilename(my-bucket, file.dat) to GcsFileOptions [userMetadata={}]
這導致異常;
