NodeJS HttpGet to a URL with JSON response

问题:

I'm new to Node development and I'm trying to make a server-side API call using a RESTful protocol with a JSON response. I've read up on both the API documentation and this SO post.

The API that I'm trying to pull from tracks busses and returns data in a JSON output. I'm confused on how to make a HTTP GET request with all parameters and options in the actual URL. The API and it's response can even be accessed through a browser or using the 'curl' command. http://developer.cumtd.com/api/v2.2/json/GetStop?key=d99803c970a04223998cabd90a741633&stop_id=it

How do I write Node server-side code to make GET requests to a resource with options in the URL and interpret the JSON response?

Thanks in advance!

The request module makes this really easy. Install request into your package from npm, and then you can make a get request.

var request = require("request")

var url = "http://developer.cumtd.com/api/v2.2/json/GetStop?" +
    "key=d99803c970a04223998cabd90a741633" +
    "&stop_id=it"

request({
    url: url,
    json: true
}, function (error, response, body) {

    if (!error && response.statusCode === 200) {
        console.log(body) // Print the json response
    }
})

You can find documentation for request on npm: https://npmjs.org/package/request
