Sending a JSON to an API Url through Ruby on Rails - ruby

Question

I have a json object that I'm sending to Google's QXP Express API. The idea is that I send the object with the relevant travel information. In terminal, through curl, it's very easy to send it. I just use the following curl command. Doc.json is the file name of the json.
curl -d #doc.json --header "Content-Type: application/json" https://www.googleapis.com/qpxExpress/v1/trips/search?key=AIzaSyAaLHEBBLCI4aHLNu2jHiiAQGDbCunBQX0
This is my code to do it in Ruby.
uri = URI('https://www.googleapis.com/qpxExpress/v1/trips/search?key=MYAPIKEY')
req = Net::HTTP::Post.new uri.path
req.body = {
"request" => {
"passengers" => {
"adultCount" => 1
},
"slice" => [
{
"origin" => "BOS",
"destination" => "LAX",
"date" => "2014-10-14"
},
{
"origin" => "LAX",
"destination" => "BOS",
"date" => "2014-11-14"
}
]
}
}.to_json
res = Net::HTTP.start(uri.host, uri.port, :use_ssl => true) do |http|
http.verify_mode = OpenSSL::SSL::VERIFY_NONE
http.ssl_version = :SSLv3
http.request req
end
puts res.body
However I'm getting back the following error.
{
"error": {
"errors": [
{
"domain": "global",
"reason": "parseError",
"message": "This API does not support parsing form-encoded input."
}
],
"code": 400,
"message": "This API does not support parsing form-encoded input."
}
}
I just need to send it with the json file, but nothing I can find online covers sending json's to APIs. Please help, I'm very stuck.

It is always matter of taste what tools you prefer, but as for me i am currently using the rest-client gem for accessing REST APIs. With this library your example could be written like this:
require 'json'
require 'rest-client'
response = RestClient.post 'https://www.googleapis.com/qpxExpress/v1/trips/search?key=AIzaSyAaLHEBBLCI4aHLNu2jHiiAQGDbCunBQX0',
{
request: {
passengers: {
adultCount: 1
},
slice: [
{
origin: "BOS",
destination: "LAX",
date: "2014-10-14"
},
{
origin: "LAX",
destination: "BOS",
date: "2014-11-14"
}
]
}
}.to_json,
:content_type => :json
puts response.body
But if you want a Net::HTTP only solution, this might not be a suitable answer for you.
