This library enables the user to write pingback aware applications. It consists of two components, the client and the server. The specs of pingback are available at hixie.ch/specs/pingback/pingback-1.0
The client provides the methods for sending pingback requests.
The server is a simple Rack application, which should be used to receive pingback requests. Notice that this class does not know how to handle a pingback request, this is application specific. Therefore a proc in which the request is handled has to be provided. This design was chosen to enable the users of this library a maximum of flexibility. The pingback specification suggest some steps on how to process a request. Personally I dont think that its a good idea to allow some strangers to request some URIs from my server.
gem install pingback
source_uri = "http://myblog.com/articles/2" target_uri = "http://someblog.com/articles/16" Pingback::Client.new.ping(source_uri, target_uri)
Notice that this class does not know how to handle a pingback request, it simply provides the general set-up. Therefore a proc in which the request is handled has to be provided.
Pingback::Server.new(Proc.new { |source_uri, target_uri| raise GenericFaultException unless Linkback.create(source_uri, target_uri) })
To mark a resource as pingback-enabled the header must contain the URI of the pingback-server in the field “X-Pingback”.
