Is there a way to integrate web services in Rails 3 by sending POST parameters to an external URL? Typically, I utilize a command line method like the one below for posting:
curl -X POST -u "v10REVkw:XuCqIhyCw" \
-H "Content-Type: application/json" \
--data '{"apids": ["c80-d363237c-e513b"], "android": {"alert": "Android Test!"}}' \
https://url/to/push
If I were to choose, I'd opt for utilizing Rest client. Take a look at this code snippet which is directly from their documentation:
RestClient.post "http://demo-site.com/data", { 'id' => 123 }.to_json, :content_type => :json, :accept => :json
Utilizing ActiveResource from the Rails package can be a helpful solution.
Below is a detailed method to accomplish your desired outcome taken from one of my valuable resources.
Simply adjust and activate with the use of remote.
def remote
begin
Net::HTTP.get_response((uri)).body
rescue
#insert custom error handling here
end
end
def gateway
'http://api.opencalais.com/enlighten/rest/'
end
def uri
URI.parse(gateway + '?' + URI.escape(post_params.collect{ |k, v| "#{k}=#{v}" }.join('&')))
end
def post_params
{
'licenseID' => @api_key,
'content' => @context
}
end
EDIT:
Make sure to include the following:
require 'uri'
require 'net/http'
require 'open-uri'
EDIT2:
If dealing with a RESTful webservice, consider utilizing ActiveResource
