Now I'm trying to use the sample code in facebook PHP SDK.
Though I can use localhost to view my web on Google Chrome broser,when I fill the URL
(I use APPSERV as my server)
localhost in the "Secure Canvas URL" blank, it always says server connection denied.
(I'm not sure if the message in English is correct.It shows "伺服器拒絕連線"on my broswer)
Thanks for everyone who answers my question.
