Event

This example demonstrates how to handle event between client and server.

1. Client will publish access event when handle http request.
2. Server will subscribe access event and update access statistics.

Protobuf

protoc --go_out=proto --micro_out=proto proto/statistics.proto

Run Server

go run event/server/main.go event/server/handler.go event/server/subscriber.go

Tips

Panic recover is required in subscribe method to prevent crash when panic occur in subscribe goroutine.

Run Client

go run event/client/main.go

Testing

curl -X POST http://localhost:80/helloworld?user=test
{"message":"Hello test"}

curl -X GET http://localhost:80/statistics?method=POST
{"access_count":1}

curl -X GET http://localhost:80/statistics?method=GET
{"access_count":1}

curl -X GET http://localhost:80/statistics
{"access_count":3}
