Constructor Details

#initialize(raw_response) ⇒ Response

Constructs a new response object from a raw_response. Provides utility methods for validating the response as authentic, and for handling the Direct Post Method relay response.

raw_response

The raw response, either a string in POST body or GET query string format, or a hash of key/value pairs.

Typical usage:

response = AuthorizeNet::SIM::Response("x_first_name=John&x_last_name=Doe")

end

#direct_post_reply(url, options = {}) ⇒ Object

Returns an HTML string that can be returned to the gateway during the Relay Response, and will send the user on to URL you specify. Takes a hash of options, currently the only option is :include, which can be True to include all fields returned in the response as query string parameters, or it can be an array of fields to include.

  js_url = url.gsub("'", '\'')
  html_url = url.gsub('&', '&').gsub('"', "\"")
  html = <<-HTML
<html><head><script type="text/javascript" charset="utf-8">window.location='#{js_url}';</script><noscript><meta http-equiv="refresh" content="1;url=#{html_url}"></noscript></head><body></body></html>
HTML
end

#direct_post_url(base_url, include_fields = true) ⇒ Object

Returns an URL with the fields found in the response and specified in include_fields attached as part of the URL’s query string. If you pass true instead of an array of fields, all fields will be attached.

#success?(api_login, merchant_value) ⇒ Boolean
