totobro-bot

A no-nonsense helper to fetch Singapore lottery results and details of the next draw.

Getting started

You will need:

1. Create a bot or get a bot token through the BotFather
2. Docker
3. ngrok
4. Postman or other REST API client

Get dependencies

go get

Change your env

Copy .dbenv_example into .dbenv. Change the credentials as necessary.

Copy .env_example into .env.

Put the token you have gotten in Getting started (1) as BOT_TOKEN

DATABASE_URL should have the credentials listed in your .dbenv.

FETCH_NEXT_DRAW_TASK_MOCK_ID can be any int64 value.

FETCH_NEXT_DRAW_TASK_USER_FIRST_NAME can be any string value.

Database

Run docker-compose up -d This will start create a postgres db using docker.

Migrations

Run:

docker run -v /absolute/path/to/migrations:/migrations --network host migrate/migrate -path=/migrations/ -database postgres://{POSTGRES_HOST}:{POSTGRES_PASSWORD}@localhost:5432/{POSTGRES_DB}\?sslmode=disable up

Build and serve your app

Run:

go build main.go bot.go
./main

This will make the app serve on 8080

Run ngrok

ngrok http 8080

This would output several URL but we are only interested in this.

...
Web Interface                 http://127.0.0.1:4040
Forwarding                    https://xxxxx-xxxx-xxx.ap.ngrok.io -> http://localhost:8080

Copy the https link. Open up your web browser or your favorite REST API client key in this and make this request.

GET https://api.telegram.org/bot{token}/setWebhook?url={https://xxxxx-xxxx-xxx.ap.ngrok.io}

You should see: {"ok":true,"result":true,"description":"Webhook was set"}

And you are good to go.

To start off, go talk to your bot and send /start to it.
