I’ve been looking for this for ages now, but this morning I actually found someone that had done this, and is still following the XML-RPC conventions. (I’ve also got a closed source version of this, included in some projects, but it doesn’t follow the XML-RPC conventions anymore).
So I was very glad to find this. But due to me not using a verified SSL certificate, I ran into some problems.
I kept getting the following error:
* SSL certificate problem, verify that the CA cert is OK. Details:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
After reading through the code, I created a modified version that solves this issue (just added an additional CURL command to ignore the problem), you can download it from this location.
