如何在没有html/js的情况下捕获fastapi websocket消息？

import asyncio
import websockets

async def receive_websocket_messages():
    async with websockets.connect('ws://localhost:8000/ws') as websocket:
        while True:
            message = await websocket.recv()
            print(f"Received message: {message}")

asyncio.run(receive_websocket_messages())

from fastapi import FastAPI, WebSocket

app = FastAPI()

@app.websocket("/ws")
async def websocket_endpoint(websocket: WebSocket):
    await websocket.accept()
    while True:
        message = await websocket.receive_text()
        print(f"Received message: {message}")
