http Post request And declaration of authorization header in rails - ruby-on-rails

I am trying to perform an HTTP authorization using Ruby on Rails. Here is what I'm trying:
res = http.post(uri.request_uri,
:Authorization => cobSessionToken,
"coBrandSessionCredential=loginToken=#{cobSessionToken}&userLogin=#{login}&userPassword=#{password}")
render :json => {"isValid" => true, "Body" => JSON.parse(res.body)}
This doesn't seem to work. How can I perform an authorization?

how about something like this?
url = URI.parse('https://my.url.com/path')
req = Net::HTTP::Post.new(url.path)
req.basic_auth 'user', 'pass'
req.use_ssl = true
req.form_data({'key1' => 'val1', 'key2' => 'val2'})
resp = Net::HTTP.new(url.host, url.port).start {|http| http.request(req) }
puts resp

I would recommend using something like postman (its a free google program you can get at the google store) to make sure the error is not on the server side. Use Net:http it comes with ruby so you do not need to install it but you have to require it.
Require it by:
require "net/http"
require "uri"
Use this cheatsheet I think you need basic_auth.rb You will see how to form the request.

How to run cURL commands in Rails

I'm using Ruby on Rails 5 and I need to execute the following command in my application:
curl -F 'client_id=126581840734567' -F 'client_secret=678ebe1b3b8081231aab27dff738313' -F 'grant_type=authorization_code' -F 'redirect_uri=https://uri.com/' -F 'code=AQBi4L2Ohy3Q_N3V48OygFm0zb3gEsL985x5TIyDTNDJaLs93BwXiT1tyGYWoCg1HlBDU7ZRjUfLL5HVlzw4G-7YkVEjp6Id2WuqOz0Ylt-k2ADwDC5upH3CGVtHgf2udQhLlfDnQz5NPsnmxjg4bW3PJpW5FaQs8fn1ztgYp-ssfAf6IRt2-sI45ZC8cqqr5K_12y0Nq_Joh0H-tTfVyNLKatIxHPCqRDb3tfqgmxim1Q' https://api.instagram.com/oauth/access_token
so that it returns something like:
{"access_token": "IGQVJYS0k8V6ZACRC10WjYxQWtyMVRZAN8VXamh0RVBZAYi34RkFlOUxXZnTJsbjlEfnFJNmprQThmQ4hTckpFUmJEaXZAnQlNYa25aWURnX3hpO12NV1VMWDNMWmdIT3FicnJfZAVowM3VldlVWZAEViN1ZAidHlyU2VDMUNuMm2V", "user_id": 17231445640157812}
Is there a way to make Rails execute those types of commands? I was trying the following:
uri = URI.parse('https://api.instagram.com/oauth/access_token')
http = Net::HTTP.new(uri.host, uri.port)
request = Net::HTTP::Post.new(uri.request_uri)
request.set_form_data({
"client_id" => "126581840734567",
"client_secret" => "678ebe1b3b8081231aab27dff738313",
"grant_type" => "authorization_code",
"redirect_uri" => "http://nace.network/",
"code" => params[:code]
})
res = Net::HTTP.start(uri.hostname, uri.port) do |http|
http.request(request)
end
but I get the following error:
end of file reached
in this line:
res = Net::HTTP.start(uri.hostname, uri.port) do |http|
http.request(request)
end
You're using HTTPS, so you need to add this to your code:
Net::HTTP.start(uri.hostname, uri.port, use_ssl: true) do |http|
res = http.request(request)
end
But if you don't need persistent connections, you could also use this:
res = Net::HTTP.post_form(uri,
"client_id" => "126581840734567",
"client_secret" => "678ebe1b3b8081231aab27dff738313",
"grant_type" => "authorization_code",
"redirect_uri" => "http://nace.network/",
"code" => params[:code]
)
Also, you could consider using a library like Faraday, which is a lot easier to deal with.
Edit
This is from TinMan's comment below, sound points.
Using cURL from inside Ruby or Rails is extremely valuable. There is an incredible amount of functionality inside cURL that isn't implemented in Rails or Ruby; Even Ruby's HTTP clients have a hard time replicating it, so cURL is very acceptable depending on the needs of the application. And, depending on the application, because cURL is in compiled C, it could easily outrun pure Ruby clients.
Curl is a means of issuing HTTP (or HTTPs) requests from the command line.
You don't want to use CURL in Rails. You want to issue HTTP requests from within Rails. Using curl is okay, it's one way to issue HTTP requests from with Rails.
We can refine that down further to, you want to issue HTTP requests from Ruby. Narrowing/distilling down to the most basic version of the problem is always good to do.
We knew all this already probably - still worth writing down for us all to benefit from!
Use HTTP in Ruby
We want to use a HTTP Client. There are many but, for this I'm going to use Faraday (a gem) 'cause I like it.
You've made a good start with Ruby's built in NET:HTTP but I prefer Faraday's DSL. It results in more readable and extendable code.
So, here is a class! I barely tested this so, use as a starting point. Make sure you write some unit tests for it.
# This is a Plain Old Ruby Object (PORO)
# It will work in Rails but, isn't Rails specific.
require 'faraday' # This require is needed as it's a PORO.
class InstagramOAuth
attr_reader :code
# The code parameter will likely change frequently, so we provide it
# at run time.
def initialize(code)
#code = code
end
def get_token
connection.get('/oauth/access_token') do |request|
request.params[:code] = code
end
end
private
def connection
#connection ||= Faraday.new(
url: instagram_api_url,
params: params,
ssl: { :ca_path => https_certificate_location }
)
end
def instagram_api_url
#url ||= 'https://api.instagram.com'
end
# You need to find out where these are for your self.
def https_certificate_location
'/usr/lib/ssl/certs'
end
def params
# These params likely won't change to often so we set a write time
# in the class like this.
{
client_id: '126581840734567',
client_secret: '678ebe1b3b8081231aab27dff738313',
grant_type: 'authorization_code',
redirect_uri: 'https://uri.com/'
}
end
end
# How do we use it? Like so
# Your big old authorisation code from your question
code = 'AQBi4L2Ohy3Q_N3V48OygFm0zb3gEsL985x5TIyDTNDJaLs93BwXiT1tyGYWoCg1HlBDU'\
'7ZRjUfLL5HVlzw4G-7YkVEjp6Id2WuqOz0Ylt-k2ADwDC5upH3CGVtHgf2udQhLlfDnQz'\
'5NPsnmxjg4bW3PJpW5FaQs8fn1ztgYp-ssfAf6IRt2-sI45ZC8cqqr5K_12y0Nq_Joh0H'\
'-tTfVyNLKatIxHPCqRDb3tfqgmxim1Q'
# This will return a Faraday::Response object but, what is in it?
response = InstagramOAuth.new(code).get_token
# Now we've got a Hash
response_hash = response.to_hash
puts 'Request made'
puts "Request full URL: #{response_hash[:url]}"
puts "HTTP status code: #{response_hash[:status]}"
puts "HTTP response body: #{response_hash[:body]}"
When I ran the snippet above I got the following. The class works, you just need to tweak the request params until you get what you want. Hopefully the class demonstrates how to send HTTP requests in Ruby/Rails.
Request made
Request full URL: https://api.instagram.com/oauth/access_token?client_id=126581840734567&client_secret=678ebe1b3b8081231aab27dff738313&code=AQBi4L2Ohy3Q_N3V48OygFm0zb3gEsL985x5TIyDTNDJaLs93BwXiT1tyGYWoCg1HlBDU7ZRjUfLL5HVlzw4G-7YkVEjp6Id2WuqOz0Ylt-k2ADwDC5upH3CGVtHgf2udQhLlfDnQz5NPsnmxjg4bW3PJpW5FaQs8fn1ztgYp-ssfAf6IRt2-sI45ZC8cqqr5K_12y0Nq_Joh0H-tTfVyNLKatIxHPCqRDb3tfqgmxim1Q&grant_type=authorization_code&redirect_uri=https%3A%2F%2Furi.com%2F

The content type 'application/x-www-form-urlencoded' is not supported in Ruby on Rails

So I'm just trying to make a simple post request using httpclient in RoR.
I'm going through a proxy, doing ntlm authentication with the server ( I can make GET requests without a problem).
Now when I try and do a post request, I get the error mentioned in the title...
proxy = ENV['HTTP_PROXY']
client=HTTPClient.new(proxy)
client.set_auth(nil,user,pass)
body= [{'Content-Type' => 'application/atom+xml, :content => ...}]
res = client.post('url',body)
puts res.body
How am i getting this error when I clearly specify the header as atom+xml..?
You should use
res = client.post('url',
:body => "...body content...",
:header => {'Content-Type' => 'application/atom+xml'})

Rails email using Postmark API on Heroku -- connection reset by peer

I have multiple bruises today, trying to learn two things at once... the API for Postmark and Rails HTTP requests.
Goal: Use Postmark add-on for Heroku to send production email.
I am trying to combine this article on HTTP requests...
http://docs.ruby-lang.org/en/2.0.0/Net/HTTP.html
... with this API reference for Postmark...
http://developer.postmarkapp.com/developer-send-api.html
Unfortunately, the examples from Postmark are done in curl and I have not succeeded in translating them into a HTTP request. I suspect the problem centers around the headers -- the parts of the transmission other than the body.
The rescue clause seen in the code below traps the error 'connection reset by peer'. At this point I don't know if I am even close to the right format for the headers that provide Postmark authentication.
I have the proper server token (in the config entry) and the From email has been given the required Postmark signature.
def send_production_email(email_address, subject, email_body)
# Use API to interact with Heroku add-on Postmark
# http://developer.postmarkapp.com/developer-send-api.html
uri = URI('https://api.postmarkapp.com/email')
# Form the request
req = Net::HTTP::Post.new(uri)
# Set request headers -- SUSPECT THIS IS WRONG
req['Accept'] = 'application/json'
req['Content-Type'] = 'application/json'
req['X-Postmark-Server-Token'] = Rails.application.config.postmark_token
rbody ={
'From' => 'Support <michael#mydomain.com>',
'To' => email_address,
'Subject' => subject,
'HtmlBody' => wrap_html(email_body),
'TextBody' => email_body
}.to_json
req.body = rbody
# Send the request, waiting for the response
begin
response = Net::HTTP.new(uri.host, uri.port).start {|http| http.request(req) }
rescue Exception => e
logthis("http request error: #{e.message}")
return
end
# ...parsing section omitted since I do not get that far...
end
A second attempt was formatted this way, but results in the same peer reset error:
rbody ={
'From' => 'Support <michael#disambiguator.com>', # TODO: replace email when domain is live
'To' => email_address,
'Subject' => subject,
'HtmlBody' => wrap_html(email_body),
'TextBody' => email_body
}.to_json
uri = URI('https://api.postmarkapp.com/email')
http = Net::HTTP.new(uri.host, uri.port)
# http.use_ssl = true
request = Net::HTTP::Post.new(uri.path, {'Content-Type' => 'application/json', 'Accept' => 'application/json', 'X-Postmark-Server-Token' => Rails.application.config.postmark_token})
request.body = rbody
# Send the request, waiting for the response
begin
response = http.request(request)
rescue Exception => e
logthis("http request error: #{e.message}")
return
end
I am grateful for any guidance!
I’m a Wildbit’s employee and the maintainer of the official Postmark Ruby gem.
The "connection reset by peer" error is the result of you trying to send an unencrypted HTTP request to an endpoint expecting secure communication via HTTPS. So, if you change this line:
Net::HTTP.new(uri.host, uri.port).start {|http| http.request(req) }
to:
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
response = http.start { |http| http.request(req) }
then you should be able to receive a response from the API. I see that you have this line in the second example, but it is commented. Since you’re doing this as an exercise, I’d like to add that when using net/http you don’t usually have to work with the underlying classes like Net::HTTP::Post. It’s generally simpler to use the higher level API provided by instances of the Net::HTTP class. Here is an example of how your method could be simplified by using it:
def send_production_email(email_address, subject, email_body)
uri = URI('https://api.postmarkapp.com/email')
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
headers = {'Accept' => 'application/json',
'Content-Type' => 'application/json',
'X-Postmark-Server-Token' => Rails.application.config.postmark_token}
payload = {'From' => 'tema#wildbit.com',
'To' => email_address,
'Subject' => subject,
'HtmlBody' => email_body,
'TextBody' => email_body}
http.post(uri.request_uri, payload.to_json, headers)
rescue => e
puts "http request error: #{e.message}"
end
And, if you’re interested in how net/http is used in the official Postmark Ruby gem, check out the HttpClient class’ source.

check https status code ruby

Is there a way to check for an HTTPS status code in ruby? I know that there are ways to do this in HTTP using require 'net/http', but I'm looking for HTTPS. Maybe there is a different library that I need to use?
You can do this in net/http:
require "net/https"
require "uri"
uri = URI.parse("https://www.secure.com/")
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
request = Net::HTTP::Get.new(uri.request_uri)
res = http.request(request)
res.code #=> "200"
Refs:
Net::HTTP cheat sheet
How to Cure Net::HTTP’s Risky Default HTTPS Behavior
You can use any wrapper around Net::HTTP(S) to get much easier behavior.
I use Faraday here ( https://github.com/lostisland/faraday ) but HTTParty has almost the same functionality ( https://github.com/jnunemaker/httparty )
require 'faraday'
res = Faraday.get("https://www.example.com/")
res.status # => 200
res = Faraday.get("http://www.example.com/")
res.status # => 200
(as a bonus you get options for parsing responses, raising state exceptions, logging requests....
connection = Faraday.new("https://www.example.com/") do |conn|
# url-encode the body if given as a hash
conn.request :url_encoded
# add an authorization header
conn.request :oauth2, 'TOKEN'
# use JSON to convert the response into a hash
conn.response :json, :content_type => /\bjson$/
# ...
conn.adapter Faraday.default_adapter
end
connection.get("/")
# GET https://www.example.com/some/path?query=string
connection.get("/some/path", :query => "string")
# POST, PUT, DELETE, PATCH....
connection.post("/some/other/path", :these => "fields", :will => "be converted to a request string in the body"}
# add any number of headers. in this example "Accept-Language: en-US"
connection.get("/some/path", nil, :accept_language => "en-US")
require 'uri'
require 'net/http'
res = Net::HTTP.get_response(URI('http://www.example.com/index.html'))
puts res.code # -> '200'
Slightly more readable way:
response.kind_of?(Net::HTTPOK)

How do I use GET and POST on Github using access tokens?

I am using OmniAuth to authenticate a user via Github. OmniAuth provides access tokens. Now I want to send the GET or POST request to Github. I don't want to use any gems, I want to do with Net::HTTP. I did it like this:
<%consumer = OAuth::Consumer.new("mshsD0jpgcYwwOEcTW5ZTA", "V6KTqllY5jS392pj4FNFCb5EiOM8DaFzVwr9cS54XQ", { :site => "https://api.github.com", :request_token_path => '/oauth/request_token', :access_token_path => '/oauth/access_token', :authorize_path => '/oauth/authorize', :scheme => :header })%>
<%access_token = OAuth::AccessToken.new(consumer,auth.token,auth.secret)%>
The same I previously did for Twitter worked fine but now I am getting the following error:
uninitialized constant ActionView::CompiledTemplates::OAuth
Even in the same application the same thing is working for Twitter but not for Github.
I searched through Google but found nothing that helped.
You should be using OAuth2 instead of OAuth. I'd actually recommend using Octokit, it's easy to use and Wynn works for GitHub now so part of his job is keeping it up to date. :)
If you want to use Net::HTTP (although I can't imagine why), you can actually do that without any gems. Just put the token you got from OmniAuth in the request's "Authentication" header.
require 'net/https'
require 'uri'
uri = uri = URI.parse("https://api.github.com/users/username")
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
headers = { "Authentication" => "token" }
request = Net::HTTP::Get.new(uri.request_uri, headers)
response = http.request(request)
response.body # => A string containing the JSON response
Seeing as you're already using Omniauth and are familiar with it, I'd recommend using the omniauth-github strategy: https://github.com/intridea/omniauth-github
