Description: ws2s--bring socket to browser-side js
        =====================================
        ws2s(websocket to socket) is a websocket server that handle socket(tcp)s.   
        
        the simplest workflow might be like this:    
        
        first, a websocket client(we called **`"ws"`**) ask ws2s_server to create a socket(we called **`"s"`**) for it.    
        then, **`"ws"`** ask ws2s_server to use **`"s"`** to send data.    
        when **`"s"`** received data, ws2s_server will notify **`"ws"`** with the received data.    
        
        ![](https://playlay.github.io/images/ws2s.png)    
        
        with this workflow, javaScript running on a browser got the ability to use socket.    
        
        
        client case
        ============
        a ws2s server at `wss://feling.io/ws2s-server/` is ready for test case
        
        ```javaScript
        var ws = new WebSocket("wss://feling.io/ws2s-server/")
        ws.onmessage = (event) => {
            console.log("onmessage: ", event.data)
        }
        ws.onopen = () => {
            console.log("onopen")
            ws.send(JSON.stringify(
                {
                    command: "connect",
                    host: "www.baidu.com",
                    port: 80
                }
            ))
            ws.send(JSON.stringify(
                {
                    command: "send",
                    data: "GET / HTTP/1.1\r\nHost: www.baidu.com\r\nConnection: close\r\n\r\n"
                }
            ))
        }
        ws.onclose = () => {
            console.log("onclose")
        }
        ```
        
        
        ws2s.js
        =================
        [ws2s-js](ws2s-js/) is a javaScript websocket client wrapper that provide socket-like interface to communicate with ws2s_server.    
        
        
        (upcoming)
        based on the socket_wrapper, other wrappers like redis_wrapper will be provided. then an online redis client will be available at [fredis](https://feling.io/redis/).    
        
        
        install
        =======
        ws2s works on py2、py3、linux、osx. i tried to support Windows, but there is too much adaptation to be handled for Windows.    
        
        if you are using python 3.6, you can install ws2s from pypi:    
        ```shell
        pip install ws2s-python --upgrade
        ```
        
        if you can't install ws2s from pypi, try install from github:    
        ```shhell
        pip install git+https://github.com/playlay/ws2s
        ```
        
        after installed ws2s:     
        `ws2sd` command can be used in shell,     
        `~/.ws2s/` directory will be created when you exec `ws2sd`      
        
        
        config
        ======
        config file is store at `~/.ws2s/config.json`.    
        
        
        protocol
        ========
        
        request
        -------
        
        all kinds of requests are listed below:     
        ```json
        {
            "command": "connect",
            "host":"127.0.0.1",
            "port":80
        }
        {
            "command": "send",
            "data":"GET / HTTP/1.1\r\nHost: 127.0.0.1\r\nConnection: close\r\n\r\n"
        }
        {
            "command": "close"
        }
        ```
        you can find out that:    
        
        1. message(we called request) send to ws2s_sever is a json format string.   
        2. a "command" field is required    
        
        response
        --------
        message(we called response) received from ws2s_sever, is a json format string too:      
        ```json
        {
            "success": true,
            "code": -1,
            "message": "recv data",
            "data": ""
        }
        ```
        ```
        As the example above:    
        - "message" field is for human.   
        - "success" field can be ignored.     
        
        when "code" field = -1, "data" field is presented.     
            that means ws2s_server received data from peer.      
        
        when "code" field = 0.      
            usually means ws2s_server successfully completed the most recent command    
        
        when "code" field > 0.      
            means something is not normal:      
            when "code" = 1:    
                unknown exception, you can submit an issue to ws2s    
        
            when "code" = 2:    
                ConnectionRefusedError raisesd when ws2s_server try to   
                connect host:port you specified    
        
            when "code" = 3:    
                IllegalSocketState, just reSend an "connect" request like:    
                {"command":"connect","host":"127.0.0.1","port":80}    
        
            when "code" = 4:    
                usually means you want ws2s_server to connect 127.0.0.1,    
                but ws2s_server refused to do that     
            
            when "code" = 5:    
                socket connection closed by socket server you connected to
        ```
