Sending data to threat analytics server

[MatejKovacic]

Example of Python3 server receiving data through HTTP post JSON call. Server is listening on port 3000 on /api/data, and storing data to dile data.json.

# Import the necessary modules
import json
from http.server import BaseHTTPRequestHandler, HTTPServer

# Define the HTTP request handler
class RequestHandler(BaseHTTPRequestHandler):
    def do_POST(self):
        # Set the response headers
        self.send_response(200)
        self.send_header('Content-Type', 'application/json')
        self.send_header('Access-Control-Allow-Origin', '*')
        self.end_headers()
        
        # Handle only POST requests to the '/api/data' endpoint
        if self.path == '/api/data':
            # Read the request data
            content_length = int(self.headers['Content-Length'])
            body = self.rfile.read(content_length)
            
            # Parse the JSON data and save it to a file
            try:
                data = json.loads(body)
                with open('data.json', 'a') as f:
                    f.write(json.dumps(data) + '\n')
                self.wfile.write(json.dumps({'success': True}).encode())
            except ValueError:
                self.send_error(400, 'Invalid JSON data')
        else:
            self.send_error(404, 'Endpoint not found')

# Create the HTTP server
server_address = ('', 3000)
httpd = HTTPServer(server_address, RequestHandler)

# Start the HTTP server
print('Server listening on port 3000')
httpd.serve_forever()

Example of curl call to the server:

curl -X POST -H "Content-Type: application/json" -d '{"PDUtype": "SMS-DELIVER", "datetime": "2023-03-21T13:28:06.419Z", "toNumber": "+386 41 123 456"}' http://localhost:3000/api/data

Content of a JSON file (cat data.json):

{"PDUtype": "SMS-DELIVER", "datetime": "2023-03-21T13:28:06.419Z", "toNumber": "+386 41 123 456"}
{"PDUtype": "SMS-DELIVER", "datetime": "2023-03-22T08:30:12.528Z", "toNumber": "+386 41 123 456"}

(This is just quick mockup.)
