I've setup Pubsub.Builder
with root url pointed to local PubSub emulator (localhost:8036
at my case). It seems to be working, I see that emulator is receiving my test pushes, but gives me error 400 Bad Request.
Publish code:
auth = GoogleCredential.getApplicationDefault(HTTP_TRANSPORT, JSON_FACTORY)
.createScoped(PubsubScopes.all());
client = new Pubsub.Builder(HTTP_TRANSPORT, JSON_FACTORY, auth)
.setApplicationName "test"
.setRootUrl("http://localhost:8036/")
.build();
msg = new PubsubMessage().encodeData("{\"a\": 1, \"b\": 2}".getBytes());
req = new PublishRequest().setMessages(Arrays.asList(msg));
client.projects()
.topics()
.publish("projects/GCLOUD-DEFAULT-PROJECT/topics/test-topic", req)
.execute();
In emulator console output I see following (that's for very basic PublishRequest
):

Seems that default PubSub client uses different protocol, but I don't see any way to configure it.
How can I use com.google.apis:google-api-services-pubsub
library with local emulator?
