Run CAKE API - MichaelPlug/CAKE-Algorand GitHub Wiki

CAKE also has an API to manage its interaction, this section describes its structure and use.

Requirement
Initialization
Run API
Run SDM and SKM servers

Requirement

You need to install flask to run the API server on your machine. Open the terminal and run pip install flask and pip install flask-cors

You need to open your terminal on path `architecture/Keys and using this command line generate a new ca certificate:

openssl req -new -newkey rsa:2048 -days 365 -nodes -x509 -keyout api.key -out api.crt

Assign the value 127.0.0.1 as Common Name.

Initialization

The database resetting and the deployment of the contract cannot be done using the API, you have to open your terminal and run in 'CAKE-Algorand/architecture' sh resetDB.sh and sh deploy.sh.

Run API

At this point is possible to lunch the API, running python3 api.py.

The terminal will show the base path to use to interact the API (in the following example it is 'http://localhost:8888/')

root@7e473ad21d74:/CAKE-Algorand/architecture# python3 api.py 
 * Serving Flask app 'api' (lazy loading)
 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.
   Use a production WSGI server instead.
 * Debug mode: off
 * Running on http://localhost:8888/ (Press CTRL+C to quit)

At this point the API is running, an it is possible interact with it. To test if the API is correctly working you can run this script and check if the request status is 200.

    import requests

    response = requests.get('http://localhost:8888/')

Run SDM and SKM servers

After the client generates a process_id, you need to put it in the .env file, after which you can launch the SDM and SKM servers, running on your terminal python3 sdm_server.py and python3 skm_server.py. Then, copy the SDM and SKM server addresses in the .env file, and the API is ready to be used for ciphering and deciphering messages.

SERVER = "172.17.0.2"
PROCESS_INSTANCE_ID=2494707248652133556
