websocket api python

Recently in a project to do need to use the WebSocket technology introduced in the HTML5, originally thought should be easy to fix, who knows in the real development after the discovery of a lot of trouble, although we are a front-end development and design of the team, And as a second-hand program apes are not to be seen for a long time, but in order to have the same needs of friends less detours, I decided to put the implementation method affixed to

This article mainly introduces a simple WebSocket server that is compatible with the old and new Socket protocols in Python, if you need it, you can refer to the WebSocket technology introduced in HTML5 that needs to be used in a recent project. I thought it would be easy to handle it, who knows that there are a lot of troubles after the development is really sta

The WebSocket technology introduced in HTML5 needs to be used in a project recently, which was supposed to be easily handled, who knows that there are a lot of troubles after the development is really started? Although we are a long-experienced team in development and design, we have never been seen as a second-hand programmer for a long time, however, I decided to stick the implementation method here to reduce detours for my friends who have the same

Summary of websocket implemented by python -- wspy Previously, we had a websocket package for php. For more information, see Websocket-php practice. Recently, we used python to perform some functions and needed websocket operation

First, the theme : Real-time display server-side dynamically generated log files Second, the process : 1. The client browser establishes a WebSocket link with the server, the server suspends the Save link instance, waits for the new content to trigger the return action 2. Log server scripts loop to discover new content and discover new lines to tornado waiting for API POST to send new content 3. The Tornado

Prior to the PHP version of the WebSocket package, see websocket--php Combat, the recent use of Python to do some functions, need to use the websocket operation, so, referring to the previous implementation, the implementation of this Python version. SOURCE See Https://githu
