How to specify httr::GET array query

Question

I am trying to compose an httr::GET query where I must use a bracketed (array) query where the url resembles:

 #target = "http://example.com?abc[]=123"

This strategy does not seem to work:

 baseurl = "http://example.com"
 qy = list(abc="123")
 httr::GET(baseurl,query=qy)

R complains about invalid characters if I try:

qy = list(abc[]="123")

Answer 1

You should be able to use

GET(url, query = list("abc[]" = 133))
