websocketd是一个很小的命令后工具，可以让你的命令行接口程序封装成可通过WebSocket进行访问。
例如这样一个命令行程序count.sh:
#!/bin/bashfor COUNT in $(seq 1 10); do echo $COUNT sleep 1done可通过如下命令进行封装：
$ websocketd --port=8080 ./count.sh然后你可以创建一个网页来测试count.html:
<!DOCTYPE html><pre id="log"></pre><script> // helper function: log message to screen function log(msg) { document.getElementById('log').textContent += msg + '\n'; } // setup websocket with callbacks var ws = new WebSocket('ws://localhost:8080/'); ws.onopen = function() { log('CONNECT'); }; ws.onclose = function() { log('DISCONNECT'); }; ws.onmessage = function(event) { log('MESSAGE: ' + event.data); };</script>
