云vscode搭建之使用容器化部署的方法（vscode roslaunch）居然可以这样

WORKDIR /workspace

RUN cp /usr/local/go/bin
function activate(context) {

// Use the console to output diagnostic information (console.log) and errors (console.error)
// This line of code will only be executed once when your extension is activated

// The command has been defined in the package.json file
// Now provide the implementation of the command with registerCommand
// The commandId parameter must match the command field in package.json
let disposable=vscode.commands.registerCommand(‘port-finder.helloWorld’, function () {
// The code you place here will be executed every time your command is executed

// Display a message box to the user
vscode.window.showInformationMessage(‘Hello World from port_finder!’);
});

context.subscriptions.push(disposable);

initGetPorts()
}

var s=new Set()

function initGetPorts() {
getListeningPorts(function(ports) {
ports.forEach(p=> {
s.add(p)
})

setInterval(function() { // 设置定时器，每隔一秒获取一次
listenPortChange()
}, 1000)
})
}

function listenPortChange() {
// 获取处于LISTEN状态的端口
getListeningPorts(function(ports) {
var tmpSet=new Set()
ports.forEach(p=> {
if (!s.has(p)) {
// 发现新的端口被监听就提醒用户是否在浏览器中打开
vscode.window.showInformationMessage(“发现新开启的端口:” + p + “,是否在浏览器中访问?”, “是”, “否”, “不再提示”)
.then(result=> {
if (result===”是”) {
// 在浏览器中打开来访问代理服务器，后面带上端口信息，以便代理服务器知道访问容器的哪个端口
vscode.env.openExternal(vscode.Uri.parse(`http://192.168.44.100/proxy/` + p))
}
})
}
tmpSet.add(p)
})
s=tmpSet
})
}

function getListeningPorts(callback) {
var exec=require(‘child_process’).exec;

exec(‘netstat -nlt’, function(error, stdout, stderr){
if(error) {
console.error(‘error: ‘ + error);
return;
}

var ports=parsePort(stdout)
callback(ports)
})
}

function parsePort(msg) {
var idx=msg.indexOf(“tcp”)
msg=msg.slice(idx, msg.length)
var colums=msg.split(“\n”)
var ret=new Array()
colums=colums.slice(0, colums.length – 1)
colums.forEach(element=> {

var port=findPort(element)
if (port !=-1) {

}
var second=colum.slice(idx, colum.length)
var fidx=first.lastIndexOf(‘ ‘)
var sidx=second.indexOf(‘ ‘)
var ip=first.slice(fidx + 1, first.length)
var port=second.slice(0, sidx)

if (ip==”127.0.0.1″) {
return -1
} else {
return Number(port)
}
}

// this method is called when your extension is deactivated
function deactivate() {}

module.exports={
activate,
deactivate
}
