How to access data requested by Post method in rails - ruby-on-rails

Question

Am trying to access data from a certain API using POST method but it returns back the actual list of params that I sent. Here is my code I don't know whether am doing this right, I will be glad for your help.
This is my controller
#Request access token from ExactApi
params = {
"code" => "#{code}",
"redirect_uri" => '/auth/exact/callback',
"grant_type" => "authorization_code",
"client_id" => "{CLIENT_ID}",
"client_secret" => "CLIENT_SECRET"
}
uri = URI.parse('https://start.exactonline.nl/api/oauth2/token')
#Encode the url into /x-www-form-urlencoded
uri.query = URI.encode_www_form(params)
#Transform http protocol into a secure protocol[https]
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_NONE # You should use VERIFY_PEER in production
#Send the request to the ExactApi and return the received data
res = Net::HTTP::Post.new(uri.request_uri)
res.set_form_data(params)
puts "Received:: "+ res.body.to_yaml
Output
code[CODE]&redirect_uri=%2Fauth%2Fexact%2Fcallback&grant_type=authorization_code&client_id=CLIENT_ID&client_secret=SECRET_ID
How can I access the actual data returned from API?

Answer 1

require "net/http"
require "uri"
uri = URI.parse('https://start.exactonline.nl/api/oauth2/token')
http = Net::HTTP.new(uri.host, uri.port)
request = Net::HTTP::Post.new(uri.request_uri)
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_NONE # You should use VERIFY_PEER in production
request.set_form_data({
"code" => "#{code}",
"redirect_uri" => '/auth/exact/callback',
"grant_type" => "authorization_code",
"client_id" => CLIENT_ID,
"client_secret" => CLIENT_SECRET
})
response = http.request(request)

However I would use Omniauth instead of reinventing the Oauth wheel. Its pretty hard to get right. If you cannot find a ready made provider then creating a custom provider is pretty simple:
require 'omniauth-oauth2'
module OmniAuth
module Strategies
class ExactOnline < OmniAuth::Strategies::OAuth2
# change the class name and the :name option to match your application name
option :name, :exactonile
option :client_options, {
:site => "https://start.exactonline.nl",
:authorize_url => "/api/oauth2/token"
}
uid { raw_info["id"] }
info do
{
:email => raw_info["email"]
# and anything else you want to return to your API consumers
}
end
def raw_info
#raw_info ||= access_token.get('/api/v1/me.json').parsed
end
end
end
end

You are using puts which outputs to the server console. I'm confused where the output is. You should set yourself up a view with the same name as the controller action your block of code is within, for example if this is the index action:
def index
params= { your_hash_keys: "value" }
end
Then you should have an index.html.erb inside the app/views/controller_name/ In your controller instead of puts "Received:: "+ res.body.to_yaml use #debug = "Received:: "+ res.body.to_yaml and inside your view do something to output it like <%= #debug.inspect %>
Alternatively, and not recommended is to render inline in the controller:
render inline: "Received:: " + res.body.to_yaml

You also should rename your params variable, since that is used by Rails for the incoming parameters. All in all I think a tutorial on MVC would be a good place to start.
