[英]Best way to handle 2 websocket connections in the same time
我正在處理來自 2 個 websocket 服務器的數據,我想知道同時處理兩個連接的最快方法是什么,因為第一個連接每 0.1-10 毫秒發送一次數據。
到目前為止我正在做的是:
import json
import websockets
async def run():
async with websockets.connect("ws://localhost:8546/") as ws1:
async with websockets.connect(uri="wss://api.blxrbdn.com/ws", extra_headers = {"Authorization": "apikey") as ws2:
sub1 = await ws1.send("subscription 1")
sub2 = await ws2.send("subscription 2")
while True:
try:
msg1 = await ws1.recv()
msg1 = json.loads(msg1)
msg2 = await ws2.recv()
msg2 = json.loads(msg2)
# process msg1 & msg2
except Exception as e:
print(e, flush=True)
asyncio.run(run())
如評論中所述,嘗試在其自己的協程中處理每個連接。 這是一個小例子:
import asyncio
import websockets
async def worker(ws, msg, t):
while True:
sub = await ws.send(msg)
print("Received from the server:", await ws.recv())
await asyncio.sleep(t)
async def run():
url1 = "ws://localhost:8765/"
url2 = "ws://something_different:8765/"
async with websockets.connect(url1) as ws1, websockets.connect(url2) as ws2:
await asyncio.gather(worker(ws1, "sub1", 1), worker(ws2, "sub2", 2))
asyncio.run(run())
