LTI 1.3 Advantage Demo Tool

This code consists an example tool that utilize the library LTI 1.3 PHP library.

Running The Example Code

Setup

The example is all written in PHP, and it also contains a docker compose file for easy setup if you have docker installed.

Registration and Deployment

First thing you will need is to configure your registration and deployment in the example code's fake registrations database.

This can be found in the example tool's code at db/configs/local.json. To configure your registration add a JSON object into a db/configs/local.json file in the following format. You can find an example of a registered tool in the db/configs/example.json file.

{
    "<issuer>" : { // This will usually look something like 'http://example.com'
        "client_id" : "<client_id>", // This is the id received in the 'aud' during a launch
        "auth_login_url" : "<auth_login_url>", // The platform's OIDC login endpoint
        "auth_token_url" : "<auth_token_url>", // The platform's service authorization endpoint
        "key_set_url" : "<key_set_url>", // The platform's JWKS endpoint
        "private_key_file" : "<path_to_private_key>", // Relative path to the tool's private key
        "deployment" : [
            "<deployment_id>" // The deployment_id passed by the platform during launch
        ]
    }
}

To register your tool inside a platform, the platform will need two URLs

OIDC Login URL: http://localhost:9001/login.php
LTI Launch URL: http://localhost:9001/game.php

These URLs may vary if you do not use docker-compose to run the tool and instead run it locally.

Running in Docker

To run in docker you will need both docker and docker-compose

To get the examples up and running in docker simply run:

docker-compose up --build

You're now free to launch in and use the tool.

Example Platform

Due to popular demand, an example platform has been added to show an example of launching into the example game.

The registration and deployment between the example platform and tool is already set up, so no configuration is needed.

To view the example platform, go to http://localhost:9001/platform

Note: The platform is for example purposes only and not a full platform library.
