websockets is a library for building WebSocket servers and clients in Python with a focus on correctness and simplicity.. Built on top of asyncio, Python’s standard asynchronous I/O framework, it provides an elegant coroutine-based API.. Here’s how a client sends and receives messages: The WebSocket Protocol enables two-way communication between a client running untrusted code in a controlled environment to a remote host that has opted-in to communications from that code. The security model used for this is the origin-based security model commonly used by web browsers. The protocol consists of an opening handshake followed by basic message framing, layered over TCP. Note: In some environments the WebSocket connection may fail due to intermediary firewalls, proxies, routers, etc. Creating your own test.
