C++ Client implementation for Cloud Pub/Sub service (TIPS) |
||||
(https://developers.google.com/apis-explorer/#p/pubsub/v1beta1/). |
||||
|
||||
"Google Cloud Pub/Sub" API needs to be enabled at |
||||
https://console.developers.google.com/project to open the access for a client. |
||||
Select the project name, select the "APIs" under "APIs & auth", and turn |
||||
on "Google Cloud Pub/Sub" API. |
||||
|
||||
To run the client from Google Compute Engine (GCE), the GCE instance needs to |
||||
be created with scope "https://www.googleapis.com/auth/cloud-platform" as below: |
||||
|
||||
gcloud compute instances create instance-name |
||||
--image debian-7 --scopes https://www.googleapis.com/auth/cloud-platform |
||||
|
||||
To run the client from GCE: |
||||
make tips_client |
||||
bins/opt/tips_client --project_id="your project id" |
||||
|
||||
A service account credential is required to run the client from other |
||||
environments, which can be generated as a JSON key file from |
||||
https://console.developers.google.com/project/. To run the client with a service |
||||
account credential: |
||||
|
||||
bins/opt/tips_client |
||||
--project_id="your project id" |
||||
--service_account_key_file="absolute path to the JSON key file" |

gRPC C# |
||||
======= |
||||
|
||||
A C# implementation of gRPC, Google's RPC library. |
||||
|
||||
EXPERIMENTAL ONLY |
||||
----------------- |
||||
|
||||
**This gRPC C# implementation is work-in-progress and is not expected to work yet.** |
||||
|
||||
- The implementation is a wrapper around gRPC C core library |
||||
- Code only runs under mono currently, building gGRPC C core library under Windows |
||||
is in progress. |
||||
- It is very possible that some parts of the code will be heavily refactored or |
||||
completely rewritten. |
||||
|
||||
CONTENTS |
||||
-------- |
||||
|
||||
- ext: |
||||
The extension library that wraps C API to be more digestible by C#. |
