Add an HTTP request¶

In this section we will show you how to add an http request to your sandbox application.

As an example, we are going to preform a GET request to CTA train tracker. which returns a total number of in-service trains for Red line route.

self.states.add('states:red', function(name) {
    return self
        .http.get(
            'http://lapi.transitchicago.com/api/1.0/ttpositions.aspx?', {
            params: {rt: 'red', key: '33305d8dcece4aa58c651c740f88d1e2', outputType: 'JSON'}
        })
        .then(function(resp) {
            return self.states.create('states:exit', { echo: resp.data});
        });
});

The HTTP request is made to that URL, with the parameters key, train route and the output type as Json. Once you’ve made the request to that URL, The .then() function will create the exit state and returns the results.
