Question

我有NodeJS App，想要开始使用OpenVPN连接。为此，我在npm（openvpn-client和openvpn-bin）上找到了2个模块 - 但是它们中的任何一个都没有好的文档和示例，但我尝试使用它们并且它没有成功。

我有一个包含540个.opvn文件的Ipvanish帐户（登录名/密码），我可以使用。我试试这个：

var openvpnmanager = require('node-openvpn');
 var openvpnBin = require('openvpn-bin');
 var path = require('path');

 var filePath = path.normalize('../geo/ipvanish/ipvanish-AU-Sydney-syd-a16.ovpn');

    var opts = {
        host: 'syd-a16.ipvanish.com', // normally '127.0.0.1', will default to if undefined
        port: 443, //port openvpn management console
        timeout: 60000, //timeout for connection - optional, will default to 1500ms if undefined
        config: filePath
    };
    var auth = {
        user: 'email@gmail.com',
        pass: 'password'
    };

    var openvpn = openvpnmanager.connect(opts)

    openvpn.on('connected', function() { 
        // will be emited on successful interfacing with openvpn instance
        console.log('connected')
        openvpnmanager.authorize(auth).then(function(res){

        });
    });

我使用这个，更有效的方式（有了它我可以处理OpenVPN连接作为子进程，关闭并重新连接）。

var exec = require('child_process').exec;
var psTree = require('ps-tree');

var kill = function (pid, signal, callback) {
    signal   = signal || 'SIGKILL';
    callback = callback || function () {};
    var killTree = true;
    if(killTree) {
        psTree(pid, function (err, children) {
            [pid].concat(
                children.map(function (p) {
                    return p.PID;
                })
            ).forEach(function (tpid) {
                try { process.kill(tpid, signal) }
                catch (ex) { }
            });
            callback();
        });
    } else {
        try { process.kill(pid, signal) }
        catch (ex) { }
        callback();
    }
};

var ovpnProcess = null;

if(ovpnProcess != null){
    console.log('close connection');
    var isWin = /^win/.test(ovpnProcess.platform);
    if(!isWin) {
        kill(ovpnProcess.pid);
    } else {
    var cp = require('child_process');
            cp.exec('taskkill /PID ' + ovpnProcess.pid + ' /T /F', function (error, stdout, stderr) {
                // more debug if you need
                // console.log('stdout: ' + stdout);
                // console.log('stderr: ' + stderr);
                // if(error !== null) {
                //      console.log('exec error: ' + error);
                // }
            });
        }
    }

//打开连接我使用这段代码：

ovpnProcess = exec('openvpn ipvanish/'+account.ip+'.ovpn');
ovpnProcess.stdout.on('data', function(data) {
    console.log('stdout: ' + data);
});
ovpnProcess.stderr.on('data', function(data) {
    console.log('stdout: ' + data);
});
ovpnProcess.on('close', function(code) {
    console.log('closing code: ' + code);
});
