Der Code zu schreiben, ua wie folgt
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
}
Ich verwende App Engine SDK 1.6.4
Danke
Ist dies auf Ihrem lokalen Entwicklungsserver oder auf dem Produktionsserver? –
Zunächst einmal, vielen Dank für Ihre Zeit. Dies war auf dem Produktionsserver. Mir wurde klar, dass ich es verpasst hatte, meinen Apps Berechtigungen zu geben. Also habe ich meine eigene Frage beantwortet – user1317673
