pass JSON to HTTP POST Request

I think the following should work:

// fire requestrequest({    url: url,    method: "POST",    json: requestData}, ...

In this case, the Content-type: application/json header is automatically added.

I worked on this for too long. The answer that helped me was at:send Content-Type: application/json post with node.js

Which uses the following format:

request({    url: url,    method: "POST",    headers: {        "content-type": "application/json",        },    json: requestData//  body: JSON.stringify(requestData)    }, function (error, resp, body) { ...

You don't want multipart, but a "plain" POST request (with Content-Type: application/json) instead. Here is all you need:

var request = require('request');var requestData = {  request: {    slice: [      {        origin: "ZRH",        destination: "DUS",        date: "2014-12-02"      }    ],    passengers: {      adultCount: 1,      infantInLapCount: 0,      infantInSeatCount: 0,      childCount: 0,      seniorCount: 0    },    solutions: 2,    refundable: false  }};request('https://www.googleapis.com/qpxExpress/v1/trips/search?key=myApiKey',        { json: true, body: requestData },        function(err, res, body) {  // `body` is a js object if request was successful});
