Nibdew bi WebSocket in Python

WebSocket huwa protokoll li jippermetti komunikazzjoni f'żewġ direzzjonijiet bejn server u klijent fuq konnessjoni kontinwa. F'dan l-artikolu, se nibdew billi nsiru familjari ma WebSocket ' fi Python.

Installazzjoni WebSocket tal-Librerija

L-ewwelnett, għandek bżonn tinstalla l- WebSocket librerija xierqa. Xi libreriji popolari jinkludu websockets, websocket-client, u autobahn.

pip install websockets

WebSocket Ħolqien ta ' Server Sempliċi

Nibdew billi noħolqu WebSocket server sempliċi. Hawn taħt hawn eżempju bl-użu tal- websockets librerija:

import asyncio  
import websockets  
  
async def handle_client(websocket, path):  
    async for message in websocket:  
        await websocket.send("You said: " + message)  
  
start_server = websockets.serve(handle_client, "localhost", 8765)  
  
asyncio.get_event_loop().run_until_complete(start_server)  
asyncio.get_event_loop().run_forever()

Stabbiliment ta WebSocket 'Konnessjoni mill-Klijent

Ladarba s-server jiġi stabbilit, tista' tistabbilixxi WebSocket konnessjoni mill-klijent:

import asyncio  
import websockets  
  
async def hello():  
    uri = "ws://localhost:8765"  
    async with websockets.connect(uri) as websocket:  
        await websocket.send("Hello, WebSocket!")  
        response = await websocket.recv()  
        print(response)  
  
asyncio.get_event_loop().run_until_complete(hello())

Billi ssegwi dawn il-passi sempliċi, ħadt pass ieħor biex tiffamiljarizza ruħek WebSocket ma' Python. Kompli esplora u tibni applikazzjonijiet eċċitanti billi tuża dan il-protokoll qawwi!
