Schema

The schema of GAPIC Showcase API can be found in schema/google/showcase/v1beta1 It's dependencies can be found in the googleapis/api-common-protos submodule.

Quick Start

This quick start guide will show you how to start the server and make a request to it.

Step 1. Run the server

Run the showcase server to allow requests to be sent to it. This opens port :7469 to send and receive requests.

$ gapic-showcase run
> 2018/09/19 02:13:09 Showcase listening on port: :7469

Step 2. Make a request

Open a new terminal window and make a request to the server.

$ gapic-showcase \
  identity \ # Service name
  create-user \ # Message name
  --user.display_name Rumble \ # Request fields
  --user.email [email protected]
> name:"users/0" display_name:"Rumble" email:"[email protected]" create_time:<seconds:1554414332 nanos:494679000 > update_time:<seconds:1554414332 nanos:494679000 >

* You can make requests to this server from your own client but an insecure channel must be used since the server does not implement auth.
