使用python连接到Flask Websocket

本文介绍了使用python连接到Flask Websocket的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我试图做的事情可能无法实现，但是就可以了.

What I'm trying to do may not be possible, but here it goes.

我已经在Flask上玩了一段时间了，并且已经使用flask-socketio创建了多个测试，允许用户在通过Web浏览器访问页面时进行即时通信.

I've been playing around with Flask for a while now, and have created several tests using flask-socketio, allowing users to communicate instantly when accessing the page via a web browser.

但是，我想知道当使用套接字模块从Python本身连接到服务器时，这种事情是否可行.在同一系统中，连接到使用套接字模块托管的Python套接字的过程很简单:

However, I was wondering if that sort of thing is possible when connecting to the server from Python itself, using the socket module. Connecting to a socket in Python that is hosted using the socket module, from the same system, is as simple as:

import socket s = socket.socket() host = socket.gethostname() port = 12345 s.connect((host, port))

然而，经过一两个小时的研究和实验，我无法弄清楚如何使用这种代码来连接烧瓶中的websocket设置.

However after an hour or two of research and experimentation, I cannot work out how to use this kind of code to connect to a websocket setup within flask.

任何帮助(或只是告诉我这是不可能的)将不胜感激！

Any help (or just telling me that it's not possible) would be much appreciated!

因此，在@Aravind的帮助下，我提出了一个仅使用python的客户端服务器解决方案的简单示例:

So, with the help of @Aravind, I've come up with a simple example for a client server solution using only python:

服务器:

from flask import Flask from flask_sockets import Sockets app = Flask(__name__) sockets = Sockets(app) @sockets.route('/echo') def echo_socket(ws): while not ws.closed: message = ws.receive() print(message) ws.send(message)

客户:

import websocket from websocket import create_connection ws = create_connection("ws://127.0.0.1:12345/echo") ws.send("hello world") ws.recv()

我现在意识到，我试图做的事情已经在多个不同的地方多次解释过，我只是没有将所有内容拼凑在一起.希望这将对像我一样对websocket感到困惑的其他人有所帮助.

I realise now that what I was attempting to do had been explained multiple times in multiple different places, I just hadn't put the pieces together. Hopefully this will help anyone else who was as confused by websockets as I was.

推荐答案

import websocket from websocket import create_connection ws = create_connection("127.0.0.1:12345") #ws.close() for closing #ws.send()enter code here #ws.recv() #pip install websocket-client
