如何从vkontakte获取长期访问令牌？

Question

I am using passport js for authenticating people in my node.js application. In case of vkontakte I got the access token which is valid for just one day? here is my code

passport.use(new VKontakteStrategy({clientID: '******',clientSecret: '********',callbackURL: "http://example.com/signin/vkontakte/callback",profileFields:     ['notify','friends','photos','notes','pages','offers','questions','wall','messages','offline']},
function (accessToken, refreshToken, profile, done) {
    process.nextTick(function () {
        console.log('vk profile: '+util.inspect(profile));
        console.log('refresh Token: '+refreshToken);
        profile.accessToken = accessToken.toString();
        return done(null, profile);
    });
}

)); ` Is there a way to increase the validity period? Help appreciated. Thanks in advance.
