Curl on Ruby on Rails - ruby-on-rails

Question

how to use curl on ruby on rails? Like this one
curl -d 'params1[name]=name&params2[email]' 'http://mydomain.com/file.json'

Answer 1

Just in case you don't know, it requires 'net/http'
require 'net/http'
uri = URI.parse("http://example.org")
# Shortcut
#response = Net::HTTP.post_form(uri, {"user[name]" => "testusername", "user[email]" => "testemail#yahoo.com"})
# Full control
http = Net::HTTP.new(uri.host, uri.port)
request = Net::HTTP::Post.new(uri.request_uri)
request.set_form_data({"user[name]" => "testusername", "user[email]" => "testemail#yahoo.com"})
response = http.request(request)
render :json => response.body
Hope it'll helps others.. :)

Here is a curl to ruby's net/http converter: https://jhawthorn.github.io/curl-to-ruby/
For instance, a curl -v www.google.com command is equivalent in Ruby to:
require 'net/http'
require 'uri'
uri = URI.parse("http://www.google.com")
response = Net::HTTP.get_response(uri)
# response.code
# response.body

The most basic example of what you are trying to do is to execute this with backticks like this
`curl -d 'params1[name]=name&params2[email]' 'http://mydomain.com/file.json'`
However this returns a string, which you would have to parse if you wanted to know anything about the reply from the server.
Depending on your situation I would recommend using Faraday. https://github.com/lostisland/faraday
The examples on the site are straight forward. Install the gem, require it, and do something like this:
conn = Faraday.new(:url => 'http://mydomain.com') do |faraday|
faraday.request :url_encoded # form-encode POST params
faraday.response :logger # log requests to STDOUT
faraday.adapter Faraday.default_adapter # make requests with Net::HTTP
end
conn.post '/file.json', { :params1 => {:name => 'name'}, :params2 => {:email => nil} }
The post body will automatically be turned into a url encoded form string.
But you can just post a string as well.
conn.post '/file.json', 'params1[name]=name&params2[email]'
