我有一个java app引擎Web服务,它使用通过Cloud Storage JSON API库访问的Google Cloud Storage.将我的SDK升级到1.19.30后,我开始从一个基本代码中获取异常,该代码从GCS中获取文件.相同的代码在早期的SDK(例如1.19.25)上运行良好,并且在部署到app引擎时也可以正常工作.所以..我想知道开发服务器中是否存在此错误.
目前,我的解决方法是使用较旧的SDK.
例外是:
com.google.apphosting.api.ApiProxy$FeatureNotEnabledException: The Files API is disabled. Further information: https://cloud.google.com/appengine/docs/deprecations/files_api

触发它的方法是:
private void getFile(HttpServletRequest req, HttpServletResponse resp, FileEntity fe) {
try {
GcsFilename filename = new GcsFilename(fe.getBucketName(), fe.getObjectName());
GcsFileMetadata metadata = GCS.getInstance().getMetadata(filename);
resp.setContentType(metadata.getOptions().getMimeType());
GcsInputChannel readChannel = GCS.getInstance().openPrefetchingReadChannel(filename, 0, GCS.BUFFER_SIZE);
GCS.copy(Channels.newInputStream(readChannel), resp.getOutputStream());
} catch (IOException e) {
