No Facebook Cookies when using getLoginURL #55

Closed confile closed 11 years ago

confile commented 11 years ago

It turns out that facebook cookies fbm and fbsr are perfectly set if I use this:

<facebook:loginLink appPermissions="${facebookContext.app.permissions}">Login</facebook:loginLink>

When I generate a login URL with: 

def auth() {
def loginUrl = facebookContext.getLoginURL(
                redirect_uri:createLink(controller:"facebookLogin",action:"successAction",absolute: true),
                scope: grailsApplication.config.grails.plugin.facebooksdk.appPermissions)

            redirect uri: loginUrl
}

I can still login, but I get no Facebook cookies set.

What is the difference? Both variants should lead to the same result.

fbsr cookie is set by the Facebook Javascript SDK. When you use a server side redirect, there is no cookie created, facebook info are passed through the app via signed_request params and stored in session scope. It is the same behaviour when you are running your apps on apps.facebook.com.
