send a binary json message to a udp server in python

To send a binary JSON message to a UDP server in Python, first you need to convert the JSON object to bytes using the json.dumps() method. Then, you can use the socket module to open a UDP socket and send the message to the server. Here's an example:

main.py
import json
import socket

# define the JSON object
message = {
    "name": "John Doe",
    "age": 42,
    "city": "New York"
}

# convert the JSON object to bytes
message_bytes = json.dumps(message).encode('utf-8')

# define the destination address and port
dest_address = '127.0.0.1'
dest_port = 5000

# create the socket and send the message
with socket.socket(socket.AF_INET, socket.SOCK_DGRAM) as udp_socket:
    udp_socket.sendto(message_bytes, (dest_address, dest_port))
478 chars
21 lines

In this example, the json.dumps() method is used to convert the message object to a string in JSON format, and then the encode() method is used to convert the string to bytes in UTF-8 format. The socket.socket() method is used to create a UDP socket with the AF_INET address family and SOCK_DGRAM transport type. Finally, the socket.sendto() method is used to send the message bytes to the destination address and port.
