sending GET/POST responses

[Gerald Yeo]

Hi group,

I'm new to node and flatiron.

I'm trying to use flatiron to create an app that uses Instagram's realtime api. So the first step is to handle the subscription, and I'm stumbling on sending back the hub.challenge response.

I tried looking at the examples in GitHub, the closes that I can get is the app.res.json function.

Can anyone point me in the right direction, either to documentation or examples?

Here's my starting app...

var flatiron = require('flatiron'),

    qs = require('qs');

// declarations

var instagramClientId = 'ID',

    instagramClientSecret = 'SECRET',

    app = flatiron.app;

app.use(flatiron.plugins.http);

app.router.configure({ 'strict':false });

//----- routes --------------------------------------------------

// index

app.router.get('/', function () {

    this.res.writeHead(200, {'content-type':'text/plain'});

    this.res.end('index');

});

// callback

app.router.path('/callback', function () {

    // GET /callback

    // If param hub.challenge is present, renders its value

    // This URL is used by subscription system of Instagram

    // to check if the callback URL provided when creating the subscription

    // is valid and works fine

    this.get(function () {

        if (this.req.query['hub.challenge'] != null) {

            //this.res.send(this.req.query['hub.challenge']);

            console.log(this.res)

        }

        else {

            app.log.info("ERROR on subscription request: %s");

        }

    });

    // post

    this.post(function () {

        // @todo

        this.res.writeHead(200, { 'content-type':'text/plain' });

        this.res.end('hello!');

    });

});

// start the server

app.start(8080, function (err) {

    if (err) {

        throw err;

    }

    var addr = app.server.address();

    app.log.info('listening on http://' + addr.address + ':' + addr.port);

});

ok, so I may have solved my own problem :)

Basically this two lines did it...

this.res.writeHead(200, { 'content-type':'text/plain' });

this.res.end(this.req.query['hub.challenge']);
