voting

In this application we will save the request in the Postgres database, but for do it, first we send the request to a RabbitMQ exchange and a consumer will process it and save in the database.

Dependencies

we can use the docker image to RabbitMQ and Posgresql. We need to create the database called votedb.

How to start

In the root directory of the application run the command of program that will send the message to the RabbitMQ:

go run main.go

After that, enter in the consumer directory and run:

go run main.go

Example of request to the api:

curl -d '{"name":"Phoenix"}' -H "Content-Type: application/json" -X POST http://localhost:8080/api/votes

Request to get the result:

curl -X GET http://localhost:8080/api/votes
