cjappl / yahoo-fantasy-bot

Dependencies

• Java 8 (JDK 8)
• Maven
• Docker
• Docker Compose
• Postgres (Optional)
• Lombok plugin for your IDE

Build

There are 3 files to copy before the bot will work properly:

1. yahoo.properties.template
2. slack.properties.template
3. jwt.properties.template

Copy each of the above and give them the following names:

1. yahoo.properties
2. slack.properties
3. jwt.properties

Ask Bryan to send you the creds. Fill in the creds in the new .properties files. Then run:

mvn clean install

from the root directory of the project

Build Docker Image

Start Docker by opening the application and then run:

docker-compose build

Run

The bot can be run as a standalone app or part of the provided Docker Compose environment.

Standalone

To run as a standalone app, first create a postgres database and configure the values in db.properties appropriately. You can easily do this by running the command

docker run -e POSTGRES_PASSWORD=postgres -p 5432:5432 -d postgres:9.5

Then run:

java -jar target/yahoo-fantasy-bot-0.1.0-SNAPSHOT.jar

Docker Compose

docker-compose up -d

Authentication

Yahoo Fantasy Bot

Based on the secret in jwt.properties, encode a JWT with the HS512 algorithm and send the following header with each request:

Authorization: Bearer <token>

Example JWT payload:

{"sub": "btrujillo","name": "Bryan Trujillo","iat": 1516239022,"exp": 1514793600}

Yahoo

Endpoints utitlizing YahooClient

It's complicated because Yahoo will not redirect to localhost after an OAuth login. Ask Bryan.

Scheduled tasks run by YahooOAuthService

The database needs to be seeded with a valid OAuth token. This can be done through the endpoint POST /tokens. Ask Bryan.
