I need to make remote procedure calls to a server that has a non-standard RPC protocol. It’s basically RPC but with extra types, no required message length declaration and it’s all done over ssl. I have a working version in perl but I’d prefer a solution in ruby. Below is what I have so far with most of the XML removed for brevity. require ‘rubygems’ require ‘http-access2’ client = HTTPAccess2::Client.new() client.ssl\_config.verify\_mode = nil body = \<\ ...blah blah... ENDXML resp = client.post("https://api.ultradns.net:8755",body) Whenever I try to talk to the server it always replies that I have a malformed POST. I’m using http-access2; someone packaged it as a gem but its not in the official repository. I’d like to know: 1. Is there a better way of doing all of this? (something other than http-access2) 2. Is there something obviously wrong with the above code? Keep in mind the XML part is verified in a working perl script. Thanks! ---

Ok I think I discovered the problem. I need to send my XML directly without any headers. Right now I’m sending something like: POST /RPC2 HTTP/1.0 User-Agent: Frontier/5.1.2 (WinNT) Host: [betty.userland.com](http://betty.userland.com) Content-Type: text/xml Content-length: 181 and the response I’m getting is that “POST /RPC2 HTTP/1.0” isn’t valid XML. 🙂 So my new question is: Does anyone know a way to write raw xml data to a given server&port with ssl? In other words do you know how to send a POST over ssl without the headers? ---

What’s running on the server, and why isn’t it looking at the post data, instead of the HTTP headers? – James B.

Man I have no idea; it isn’t my server but I have to talk to it. I have a solution that involves hacking up the http-access2 code so it doesn’t dump the header. If anyone has done anything like writing raw data to an ssl connection let me know. ---

I’ve not done it in Ruby, but some C examples: [An Introduction to OpenSSL Programming, Part I of II | Linux Journal](http://www.linuxjournal.com/article/4822) request\_len=strlen(request); r=SSL\_write(ssl,request,request\_len); switch(SSL\_get\_error(ssl,r)){ } ``` http://www-128.ibm.com/developerworks/linux/library/l-openssl.html if(BIO_write(bio, buf, len) <= 0) { } ``` ---
