XML-RPC Example

This is a toy example of XML-RPC in Python and Nodejs.

Usage:

$ python server.py

In a separate shell:

$ python client.py

Or to use the node client

$ node client.js

client.js

const xmlrpc = require('xmlrpc'); // npm install xmlrpc

const client = xmlrpc.createClient({host: 'localhost', port: '8000'})
client.methodCall('respond', [21], (error, resp) => {
  if (error) {
    console.log(`Something went wrong! ${error}`);
    return 1;
  }
  console.log(resp.ptime.toLocaleString());
  console.log(JSON.stringify(resp));
});

client.py

from xmlrpc.client import ServerProxy
import datetime

proxy = ServerProxy("http://localhost:8000/")

resp = proxy.respond(12)
print(resp)

server.py

from datetime import datetime
from dataclasses import dataclass
from xmlrpc.server import SimpleXMLRPCServer
import xmlrpc.client


@dataclass
class Answer:
    value: int
    description: str = 'The secret to the universe'


@dataclass
class Response:
    answer: Answer
    ptime: datetime

    @classmethod
    def respond(cls, input):
        return cls(
            answer=Answer(value=2 * input),
            ptime=datetime.now(),
        )


server = SimpleXMLRPCServer(("localhost", 8000))
print("Listening on port 8000...")
server.register_function(Response.respond, "respond")
server.serve_forever()
