Built on top of asyncio hello(): uri = "ws://localhost:8765" async with websockets.connect(uri) as websocket: await websocket.send("Hello world!") await websocket.recv() asyncio.get_event_loop().run_until_complete(hello()) And here’s /usr/bin/env python import asyncio import websockets async def echo(websocket, path): async for message in websocket: await websocket.send(message) start_server = websockets.serve(echo, "localhost", 8765)

Index 29 i ii websockets Documentation, Release 3.4 websockets is a library for developing WebSocket servers and clients in Python. It implements RFC 6455 with a focus on correctness and simplicity Here’s a WebSocket server example. It reads a name from the client, sends a greeting, and closes the connection. #!/usr/bin/env python import asyncio import websockets async def hello(websocket, path): path): name = await websocket.recv() print("< {}".format(name)) greeting = "Hello {}!".format(name) await websocket.send(greeting) print("> {}".format(greeting)) start_server = websockets.serve(hello, 'localhost'

ThinkJS 是⼀一款⾼高效、简单易⽤用的 Node.js MVC 框架。基于 ES6 Promise 开发，让异步编程更加简单、⽅方便。 ⾃自动启动服务 ⽀支持 Http、命令⾏行、WebSocket、Restful等多种⽅方式调⽤用 CBD 架构，MVC 模式 基于 Promise，异步编程更加简单 封装了 Db, Cache, Session 等常⽤用功能 开发模式下⽂文件修改后⽴立即⽣生效，⽆无需重启 // ⽤用户名 'db_pwd': '', // 密码 'use_websocket': true, // 使⽤用 websocket } JavaScript 注意： 配置参数的 key 不区分⼤大⼩小写（key 会强制转为⼩小写）。建议使⽤用⼩小写，便于阅读。 配置值除了是 return self.success(); }) ThinkJS 可以⽆无缝的⽀支持 websocket ，写 WebSocket 的逻辑和普通的 Http 请求的⽅方式⼀一致，底层使⽤用了 websocket-driver 模块。 websocket 的功能默认是关闭的，使⽤用 WebSocket 需要开启下⾯面的配置： 还有下⾯面的配置可以设置： 为了更好的规范浏览器端和服务端之间传送的数据格式，ThinkJS
