POST Requests with Ruby Faraday OpenSSL PKCS12 - ruby

Question

Good day!
I am trying to send POST requests to a server via ssl connection with .p12 certificate from Windows 7 with Ruby's Faraday library.
Ruby's version is ruby 2.3.3p222 (2016-11-21 revision 56859) [x64-mingw32]
Faraday gem's version are: faraday (0.14.0, 0.9.2)
1) I have a folder with the following cert files:
[cert_name].crt,
[cert_name].csr,
[cert_name].key,
[cert_name].p12
2) As to the code, I have the following:
require "faraday"
require "json"
require "openssl"
data = [JSON_object]
host = 'https://[domain_name]'
url = '[string]/[string]'
p12 = OpenSSL::PKCS12.new(File.open('[path_to_folder_with_cert_files]/[cert_name].p12', "rb").read, "[password]")
key = p12.key
cert = p12.certificate
connection = Faraday::Connection.new host, :ssl => {
:client_cert => cert,
:client_key => key,
:ca_file => '[path_to_folder_with_cert_files]/[cert_name].crt',
:verify => false
}
puts response.status = connection.post do |req|
req.url(url)
req.headers['Content-Type'] = #headers["content_type"]
req.body = data
end
Response has 403 Forbidden. I have tested with no ssl connection the data, url, host parameters and the status is 200 OK.
Please help, as I have found no tutorial / question to this particular use of Ruby's Faraday and OpenSSL::PKCS12

Answer 1

The following worked for me:
class Gateway
def call
connection.get do |req|
req.url(url)
req.headers['Content-Type'] = 'text/xml'
req.body = data
end
end
def connection
Faraday.new(ssl: ssl) do |builder|
builder.request :retry
builder.response(:logger) unless Rails.env.test?
builder.adapter :net_http
end
end
def ssl
{
client_key: client_key,
client_cert: client_cert,
ca_file: 'CA.crt' # optional
}
end
def url
'https://...'
end
def client_key
p12.key
end
def client_cert
p12.certificate
end
def p12
OpenSSL::PKCS12.new(p12_file.read, p12_password)
end
def p12_file
File.open('<path-to-p12-file>', 'rb')
end
def p12_password
'password' # if password protected
end
end
And the usage:
puts Gateway.new.call.body
