I have been using for a month or so and I really enjoy it. I'm now a bit struggling when it comes to using the RCurl/XML/JSON packages.I have 2 separate problems:1- A web service is published at a specific url and accepts the following HTML queries:\[code\]<Object_Request><id>1253</id></Object_Request>\[/code\]How can I embed the id number in my request? Shall I use getURL() or postForm() ?2- Another test for me is to use the Amara API (here: http://amara.readthedocs.org/en/latest/api.html) I tried to use the postForm(): \[code\]postForm(url,.params=c("X-api-username:"=my_user_id, "X-apikey:"=my_code))\[/code\]and I got the following error message:\[code\]Error in function (type, msg, asError = TRUE) : SSL certificate problem, verify that the CA cert is OK. Details:error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed\[/code\]Same thing with getURL:\[code\]getURL(url,httpheader=c("X-api-username:"=my_user_id, "X-apikey:"=my_code) )\[/code\]Any help is much appreciated.
