问题 I'm creating a facebook app with a Perl backend. The problem is that since Facebook sends the request to my web app as a POST request I'm having a problem getting the GET parameters that were also part of the base URL for the application -- in effect I'm only getting the POST params from $CGI->Vars. 回答1: See CGI/MIXING POST AND URL PARAMETERS.
