Put some traps to capture the nasty websocket._exceptions.WebSocketConnectionClosedException: Connection is already closed? Let's see if they will work. For anyone wishing to help, please install: pip install git+https://github.com/slazarov/python-bittrex-websocket.git@0.0.6.3 Owner slazarov com...

My slack team has 9,500+ users and upon bot application startup will experience a "connection is already closed" In commit 875839b - slackclient/_server.py.rtm_connect(self, reconnect=False): If line 74 self.connect_slack_websocket(self.ws_url) is moved before if not reconnect: on line...

多个协程读取websocket 返回的数据会报错,错误:cannot call recv while another coroutine is already waiting for the next message 题目来源及自己的思路 client.py 里同时实现主动请求及被动接收广播的数据 ws.py 里,在异步协程里收发请求 基本确定 是ws.py 有两个地方的协程都在读取websocket的数据导致。

Create the WebSocket Let’s dive into the code. In order to use subscriptions, the first step is to create a WebSocket connection. We use thewebsocket-clientlibrary for Python which provides both low and high-level abstractions of the WebSocket. In order to connect to AppSync, we have to ...
