Ruby https POST with headers - ruby

Question

How can I make a Https post with a header in Ruby with a json?
I have tried:
uri = URI.parse("https://...")
https = Net::HTTP.new(uri.host,uri.port)
req = Net::HTTP::Post.new(uri.path)
req['foo'] = bar
res = https.request(req)
puts res.body

Answer 1

The problem it was a json. This solve my problem. Anyway, my question was not clear, so the bounty goes to Juri
require 'uri'
require 'net/http'
require 'net/https'
require 'json'
#toSend = {
"date" => "2012-07-02",
"aaaa" => "bbbbb",
"cccc" => "dddd"
}.to_json
uri = URI.parse("https:/...")
https = Net::HTTP.new(uri.host,uri.port)
https.use_ssl = true
req = Net::HTTP::Post.new(uri.path, initheader = {'Content-Type' =>'application/json'})
req['foo'] = 'bar'
req.body = "[ #{#toSend} ]"
res = https.request(req)
puts "Response #{res.code} #{res.message}: #{res.body}"

Answer 2

Try:
require 'net/http'
require 'net/https'
uri = URI.parse("https://...")
https = Net::HTTP.new(uri.host,uri.port)
https.use_ssl = true
req = Net::HTTP::Post.new(uri.path)
req['foo'] = bar
res = https.request(req)
puts res.body

Here's a cleaner way to use Net::HTTP. If you just want to get the response and throw other objects away this is quite useful.
require 'net/http'
require 'json'
uri = URI("https://example.com/path")
res = Net::HTTP.start(uri.host, uri.port, use_ssl: true) do |http|
req = Net::HTTP::Post.new(uri)
req['Content-Type'] = 'application/json'
# The body needs to be a JSON string, use whatever you know to parse Hash to JSON
req.body = {a: 1}.to_json
http.request(req)
end
# The "res" is what you need, get content from "res.body". It's a JSON string too.

A secure-by-default example:
require 'net/http'
require 'net/https'
req = Net::HTTP::Post.new("/some/page.json", {'Content-Type' =>'application/json'})
req.body = your_post_body_json_or_whatever
http = Net::HTTP.new('www.example.com', 443)
http.use_ssl = true
http.ssl_version = :TLSv1 # ruby >= 2.0 supports :TLSv1_1 and :TLSv1_2.
# SSLv3 is broken at time of writing (POODLE), and it's old anyway.
http.verify_mode = OpenSSL::SSL::VERIFY_PEER # please don't use verify_none.
# if you want to verify a server is from a certain signing authority,
# (self-signed certs, for example), do this:
http.ca_file = 'my-signing-authority.crt'
response = http.start {|http| http.request(req) }

Its working, you can pass data and header like this:
header = {header part}
data = {"a"=> "123"}
uri = URI.parse("https://anyurl.com")
https = Net::HTTP.new(uri.host,uri.port)
https.use_ssl = true
req = Net::HTTP::Post.new(uri.path, header)
req.body = data.to_json
res = https.request(req)
puts "Response #{res.code} #{res.message}: #{res.body}"
