コードiaは次のとおりです
FileService fileService = FileServiceFactory.getFileService();
GSFileOptionsBuilder optionsBuilder = new GSFileOptionsBuilder()
.setBucket("mybucket")
.setKey(key)
.setMimeType("text/html")
.setAcl("public-read")
.addUserMetadata("myfield1", "my field value");
try {
AppEngineFile writableFile = fileService.createNewGSFile(optionsBuilder.build());
// Open a channel for writing
boolean lockForWrite = false;
FileWriteChannel writeChannel = fileService.openWriteChannel(writableFile, lockForWrite);
PrintWriter out = new PrintWriter(Channels.newWriter(writeChannel, "UTF8"));
out.println(value);
out.close();
writeChannel.closeFinally();
} catch (IOException e) {
// TODO Auto-generated catch block
}
App EngineSDK1.6.4を使用しています
