Web of Needs Bot Skeleton

December 12, 2019 ยท View on GitHub

This skeleton contains a bot that creates a Service Atom that one can connect to. For each atom that has been created on the configured node(s), the bot sends a message with the atomUri of the created Atom to everyone that is connected to the Service Atom.

The Bot Skeleton is a Spring Boot Application.

Running the bot

Prerequisites

  • Openjdk 8 - the method described here does not work with the Oracle 8 JDK!
  • Maven framework set up
  • Use this repository as a template (green button in github GUI), fork it, or clone it.

On the command line

cd bot-skeleton
export WON_NODE_URI="https://hackathonnode.matchat.org/won"
mvn clean package
java -jar target/bot.jar

Now go to What's new to find your bot, connect and create an atom to see the bot in action.

In Intellij Idea

  1. Create a run configuration for the class won.bot.skeleton.SkeletonBotApp
  2. Add the environment variables
  • WON_NODE_URI pointing to your node uri (e.g. https://hackathonnode.matchat.org/won without quotes)

to your run configuration.

  1. Run your configuration

If you get a message indicating your keysize is restricted on startup (JCE unlimited strength encryption policy is not enabled, WoN applications will not work. Please consult the setup guide.), refer to Enabling Unlimited Strength Jurisdiction Policy to increase the allowed key size.

Optional Parameters for both Run Configurations:
  • WON_KEYSTORE_DIR path to folder where bot-keys.jks and owner-trusted-certs.jks are stored (needs write access and folder must exist)

Start coding

Once the skeleton bot is running, you can use it as a base for implementing your own application.

  • Add/edit config files in src/main/resources
  • Follow the Mini HowTos.
