I get an odd 401 response preforming a get, linkedin API

问题

This gives me the proper response:

"https://api.linkedin.com/v1/people/~?oauth2_access_token="+AToken;

This gives a 401.... not sure why.

"http://api.linkedin.com/v1/people/url=www.linkedin.com%2Fin%2Fpersoniamusing?oauth2_access_token="+AToken

the exception I catch:

System.Net.WebException: The remote server returned an error: (401) Unauthorized. at System.Net.WebClient.DownloadDataInternal(Uri address, WebRequest& request)
