How do I touch a URL with rails?

StackOverflow https://stackoverflow.com/questions/8387580

Question

I have a json URL supplied by sendgrid. All it needs to be is touched. How would I do this?

def suspend
  @user = User.find(params[:id])
  @user.update_attribute("suspended", true)

  # the url I need to touch => https://sendgrid.com/api/unsubscribes.add.xml?api_user=username%40website.com&api_key=secret_password&email=#{@user.email}

end
Was it helpful?

Solution

You can use Net::HTTP.get from standard library (see docs):

require 'net/http'
Net::HTTP.get URI("https://sendgrid.com/api/unsubscribes.add.xml?api_user=username%40website.com&api_key=secret_password&email=#{@user.email}")

Updated:

For HTTPS you can do smth like that:

require "net/https"

uri = URI.parse("https://www.google.com")
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_NONE

request = Net::HTTP::Get.new(uri.request_uri) 
# request = Net::HTTP::Head.new(uri.request_uri) - get response without body

response = http.request(request)

Nice article on the subject - Ruby Net::HTTP Cheat Sheet.

OTHER TIPS

Install httpclient gem

HTTPClient.get("https://sendgrid.com/api/unsubscribes.add.xml?api_user=username%40website.com&api_key=secret_password&email=#{@user.email}")

require 'open-uri'
open("http://pragprog.com/") { |f| f.gets  }

result? just one row, not the whole page:
