Closes #7
@kbvernon reported that
https://services.arcgisonline.com/arcgis/rest/services/USA_Topo_Maps/MapServer
would not work witharc_open()
. This was an idiosyncrasy wheref=json
was being passed in the request body. But this service does not work with f=json in the body but requires it as a part of the url query.This PR makes sure that
f=json
is added to the URL instead of the body. The token, if present, is added usinghttr2::req_auth_bearer_token()
.
