setting query params to RESTful API with getURL in RCurl

Question

I would like to translate the following HTTP GET command to work with RCurl:

curl -G https://api.example.com/resource \
-d "param=value" \
-d "param=value" \
-u 'user:password'

Here is my attempt using getURL in RCurl:

getURL("https://api.example.com/resource",
userpwd ="username:password",param="value",param="value")

The first code block works fine in my command line terminal and I have no troubles using getURL until I try to set parameters; I get warning messages saying that the params are "Unrecognized CURL options". Any ideas?

posted my RCurl attempt. – user2844910 Oct 07 '13 at 01:37 — user2844910, Oct 07 '13 at 01:37

Anything going to the ... argument is interpreted as a curl option. You need to put parameters as a list in the httpheader argument. See documentation.

Try something like:

getURL("https://api.example.com/resource",
       userpwd ="username:password",
       httpheader=list(param1="value",param2="value"))
