Python3+WebSockets实现

2.1 python服务端代码

import asyncio
import websockets

# 检测客户端权限,用户名密码通过才能退出循环
async def check_permit(websocket):
    while True:
        recv_str = await websocket.recv()
        cred_dict = recv_str.split(":")
        if cred_dict[0] == "admin" and cred_dict[1] == "123456":
            response_str = "congratulation, you have connect with server\r\nnow, you can do something else"
            await websocket.send(response_str)
            return True
        else:
            response_str = "sorry, the username or password is wrong, please submit again"
            await websocket.send(response_str)

# 接收客户端消息并处理,这里只是简单把客户端发来的返回回去
async def recv_msg(websocket):
    while True:
        recv_text = await websocket.recv()
        response_text = f"your submit context: {recv_text}"
        await websocket.send(response_text)

# 服务器端主逻辑
# websocket和path是该函数被回调时自动传过来的,不需要自己传
async def main_logic(websocket, path):
    await check_permit(websocket)

    await recv_msg(websocket)

# 把ip换成自己本地的ip
start_server = websockets.serve(main_logic, '10.10.6.91', 5678)
# 如果要给被回调的main_logic传递自定义参数,可使用以下形式
# 一、修改回调形式
# import functools
# start_server = websockets.serve(functools.partial(main_logic, other_param="test_value"), '10.10.6.91', 5678)
# 修改被回调函数定义,增加相应参数
# async def main_logic(websocket, path, other_param)

asyncio.get_event_loop().run_until_complete(start_server)
asyncio.get_event_loop().run_forever()

2.2 python版客户端代码

import asyncio
import websockets

# 向服务器端认证,用户名密码通过才能退出循环
async def auth_system(websocket):
    while True:
        cred_text = input("please enter your username and password: ")
        await websocket.send(cred_text)
        response_str = await websocket.recv()
        if "congratulation" in response_str:
            return True

# 向服务器端发送认证后的消息
async def send_msg(websocket):
    while True:
        _text = input("please enter your context: ")
        if _text == "exit":
            print(f'you have enter "exit", goodbye')
            await websocket.close(reason="user exit")
            return False
        await websocket.send(_text)
        recv_text = await websocket.recv()
        print(f"{recv_text}")

# 客户端主逻辑
async def main_logic():
    async with websockets.connect('ws://10.10.6.91:5678') as websocket:
        await auth_system(websocket)

        await send_msg(websocket)

asyncio.get_event_loop().run_until_complete(main_logic())
