我试图让我的Facebook应用程序有英文和日文版。是否有可能拥有多种语言的Facebook应用程序?
我尝试使用标签,但不能让他们的工作: http://developers.facebook.com/docs/internationalization/
我当时以为我只是使应用程序的两个版本,一个在英国,另一个在日本。当我打开我的应用程序时,会显示oauth权限对话框。我批准了该应用程序,然后它将我带到一个循环的页面,每次生成一个新的$ _GET ['code']。然后,我点击屏幕左上角的“脸谱”。然后我再次点击我的应用程序,这次我可以用英语或日语访问它。我怎样才能阻止应用程序第一次循环?如何根据用户区域设置直接转到应用程序的版本?谢谢
