使用Facebook应用程序登录时出错

Question

I am trying to develop a fb app. It shows me a error message when I try to log in with the app.

API Error Code: 191 API Error Description: The specified URL is not owned by the application Error Message: Invalid redirect_uri: Given URL is not allowed by the Application configuration.

app domain:www.abc.def.com

site url :http://www.abc.def.com/

Canvas URL:http://www.abc.def/fbapp/

Answer 1

check your redirect_url

The redirect_url must contain the Site URL or Canvas URL as defined in your App Settings. If one has a trailing slash the other must too.

You will find that this is the most common solution to this problem.
