Python websockets客户端保持连接打开

Question

在Python中，我将“WebSockets”库用于websocket客户端。

import asyncio
import websockets

async def init_sma_ws():
    uri = "wss://echo.websocket.org/"
    async with websockets.connect(uri) as websocket:
        name = input("What's your name? ")

        await websocket.send('name')
        greeting = await websocket.recv()

问题是一旦收到响应，客户端websocket连接就会断开。我希望连接保持打开，以便以后可以发送和接收消息。

为了保持websocket打开并能够在以后发送和接收消息，我需要做哪些更改？

我认为您的websocket由于在recv()之后退出上下文管理器而断开连接。这样的代码工作得很好：

import asyncio
import websockets


async def init_sma_ws():
    uri = "wss://echo.websocket.org/"
    async with websockets.connect(uri) as websocket:
        while True:
            name = input("What's your name? ")
            if name == 'exit':
                break

            await websocket.send(name)
            print('Response:', await websocket.recv())


asyncio.run(init_sma_ws())
