Posted 2020-11-02 Blade blog

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")
