Desktop application (Python)

Set up and Activate virtualenv:

virtualenv venv
source venv/bin/activate

Use pip to install python-bitcoinrpc within the environment:

pip3 install python-bitcoinrpc

Create a new file named desktopapp.py and paste the code below into it.

    from __future__ import print_function
    from bitcoinrpc.authproxy import AuthServiceProxy, JSONRPCException

    rpc_port = 18884
    rpc_user = 'user1'
    rpc_password = 'password1'

    try:
        rpc_connection = AuthServiceProxy("http://%s:%s@127.0.0.1:%s"%(rpc_user, rpc_password, rpc_port))
        
        result = rpc_connection.getwalletinfo()
        
        print(result["balance"]["bitcoin"])
    except JSONRPCException as json_exception:
        print("A JSON RPC Exception occured: " + str(json_exception))
    except Exception as general_exception:
        print("An Exception occured: " + str(general_exception))

Execute:

python3 desktopapp.py

When finished, deactivate vitualenv:

deactivate

Web application (Python)

Install Flask web application framework:

pip3 install Flask

Create a new file named webapp.py and paste the code below into it.

from flask import Flask
from bitcoinrpc.authproxy import AuthServiceProxy, JSONRPCException

app = Flask(__name__)

@app.route("/")
def elements():
    rpc_port = 18884
    rpc_user = 'user1'
    rpc_password = 'password1'

    try:
        rpc_connection = AuthServiceProxy("http://%s:%s@127.0.0.1:%s"%(rpc_user, rpc_password, rpc_port))
    
        result = rpc_connection.getwalletinfo()
    
    except JSONRPCException as json_exception:
        return "A JSON RPC Exception occured: " + str(json_exception)
    except Exception as general_exception:
        return "An Exception occured: " + str(general_exception)

    return str(result['balance']['bitcoin'])

if __name__ == "__main__":
    app.run()

Start the web server and execute the code:

FLASK_APP=webapp.py flask run

When finished, deactivate vitualenv:

deactivate
