getaddrinfo: No such host is known

I am trying to setup a wordpress xml-rpc with rails:

blog = XMLRPC::Client.new("localhost/blog", "/xmlrpc.php", 80)

However, when I try to call something like

connection.call(
          'wp.getCommentCount',
          1,
          'username',
          'password',
          1

I get the following error:

getaddrinfo: No such host is known. 

This only happens in my localhost (I'm using xampp), on the live website it works fine. What can this be?

If I go directly to loc开发者_如何学编程alhost/blog/xmlrpc.php I get XML-RPC server accepts POST requests only. which means it's working fine. I don't understand what can be messing this up... thanks for any help.

Instead, try

blog = XMLRPC::Client.new("localhost", "/blog/xmlrpc.php", 80)

I have this tested on my WordPress site and it works for me.

Try putting "http://localhost/blog" and not "localhost/blog".
