web socket server code, 调用 shell exec child_process

var child_process = require('child_process');

var ws = require("nodejs-websocket");

console.log("开始建立连接...")

var server = ws.createServer(function(conn){

conn.on("text", function (str) {

var arr=str.split(" ");

var comm=arr.shift();

console.log("收到的信息为:"+str)

console.log("******"+comm+"*******");

var command = comm;

var argF=arr;

var spawnObj = child_process.spawn(comm,arr, {encoding: 'utf-8'});

spawnObj.stdout.on('data', function(chunk) {

console.log("pppp"+chunk.toString());

conn.sendText(chunk.toLocaleString());

});

});

conn.on("close", function (code, reason) {

console.log("关闭连接")

});

conn.on("error", function (code, reason) {

console.log("异常关闭")

});

}).listen(8002)

console.log("WebSocket建立完毕")
