Perform the following steps to perform user authentication through RPC:

1. Add the jsonrpc_authenticate.py file. You can place this file anywhere you want because the RPC program will work independently.
2. Add the following code to the file:

import json
import random
import requests


server_url = 'http://localhost:8069'
db_name = 'test-12'
username = 'admin'
password = 'admin'

json_endpoint = "%s/jsonrpc" % server_url
headers = {"Content-Type": "application/json"}

def get_json_payload(service, method, *args):
    return json.dumps({
        "jsonrpc": "2.0",
        "method": 'call',
        "params": {
            "service": service,
            "method": method,
            "args": args
        },
        "id": random.randint(0, 100000000),
    })

payload = get_json_payload("common", "login", db_name, username, password)
response = requests.post(json_endpoint, data=payload, headers=headers)
user_id = response.json()['result']

if user_id:
    print("Success: User id is", user_id)
else:
    print("Failed: wrong credentials")

3. Run the Python script from the Terminal with the following command:

python3 jsonrpc_authenticate.py

When you run the preceding program and you have passed a valid login name and password, the program will print a success message with id of the user, as follows:
