Google Flight RPC

system · November 11, 2013, 9:32pm

Does anyone know how to use Google Flight RPC (www.google.com/flights/rpc) or how to post a json array to it? The only documentation I’ve found for it is www.nohup.in/blog/using-json-google-flights. It shows the responses and part of the requests. I’m not sure how to build and post a json array using the following example from part 1 of the linked documentation.

[,[[,"fs","[,[,[\"SJC\"]\n,\"2012-04-05\",[\"EWR\",\"JFK\",\"LGA\"]\n,\"2012-04-12\"]\n]\n"] ] ,[,[[,"b_ca","54"] ,[,"f_ut","search;f=SJC;t=EWR,JFK,LGA;d=2012-04-05;r=2012-04-12"] ,[,"b_lr","11:36"] ,[,"b_lr","1:1528"] ,[,"b_lr","2:1827"] ,[,"b_qu","3"] ,[,"b_qc","1"] ] ] ]

Also, how do I set up the necessary headers using cURL?

#! /usr/bin/ruby
require 'mechanize'
require 'json'
require 'pp'


start_date = "2012-12-18"
end_date = "2013-01-02"
start_location = "LAX,LGB,SNA,BUR,ONT"
end_location = "VIE"

json_start_location = start_location.split( ',' ).map { |location| '\"' + location + '\"' }.join( ',' )


def make_google_api_request( json )
  headers = {}
  headers['Content-Type'] = 'application/json; charset=utf-8'
  headers['X-GWT-Permutation'] = '475BAF4AEBA848B4F2A7E0E8803D533E'
  headers['X-GWT-Module-Base']='http://www.google.com/flights/static/'
  headers['Referer']='http://www.google.com/flights/'
