@blowmage thank you. I can use it.
Are there api document of SubscriberClient ??
I wanna use streaming function.

You can find the SubscriberClient documentation here:

https://googlecloudplatform.github.io/google-cloud-ruby/#/docs/google-cloud-pubsub/v0.29.0/google/cloud/pubsub/v1/subscriberclient

The Pub/Sub gem has two different APIs, the public API and the low-level API. SubscriberClient is the low-level API. I would suggest looking at Subscriber#listen, which is the public API for streaming subscription messages.
