[Facebooker-talk] Facebooker::Session::IncorrectSignature exception when adding application

Whenever a user adds my application Facebooker will throw a
Facebooker::Session::IncorrectSignature exception. Upon further
investigation I was finding that while the expected signature was blank, the
actual signature was the facebook app secret key. why is this happening?

Whenever a user adds my application Facebooker will throw a

was finding that while the expected signature was blank, the actual signature
was the facebook app secret key. why is this happening?

[Facebooker-talk] Facebooker::Session::IncorrectSignature exception when adding application

I was thinking that and I could be wrong but you know I looked at example
after example and I haven''t seen anyone do an :exclude for the
ensure_facebook_application_is_installed with exception for a
''remove_app''
method. Am I wrong? What if I wanted to access show facebook data on the
first page?

I think I saw this, and the problem was the post-add URL defined in the FB
app page needs to go to a controller action that skips the
ensure_facebook_application_is_installed filter.

[Facebooker-talk] Facebooker::Session::IncorrectSignature exception when adding application

I have,
   ensure_application_is_installed_by_facebook_user :except => [:uninstall]
in my controller.  I can''t see how that would cause problems?

Also, my post-add url hits a controller protected by the ensure 
installed filter.  No problem for me there either.  One note, make sure in 
your FB setting your post-add url is your canvas page (not your server 
like your callback url).

Maybe, Dave''s Facebooker Tutorial section "make user add
application"
would help?  FB authentication can be tricky.

I did the same thing with my app

same thing here - my app in post add (even though my app fails during the
add)  works perfectly fine

I''m assuming your callback url calls an ''add'' method
for your app
besides saving facebook uids - does it do anything like app redirection?

For some reason, I don''t know why - facebooker things the actual
signature
during an application add, is my app''s secret key - when it''s
supposed to be
blank...

I put my first app on RubyForge.  It''s pretty bloated, a stupid idea,
and
very poorly done, but it works (or at least did at one point).  If
you''re
desperate do a,
 	svn checkout svn://rubyforge.org/var/svn/couple-rater
Look at trunk/app/controller/application.rb.  I put all the 
install/uninstall code in my base controller.

[Facebooker-talk] Facebooker::Session::IncorrectSignature exception when adding application

I am still having troubles with this exception. I ended up commenting out the
piece of code that throws the exception and things work just fine after that...

I have 
before_filter :ensure_authenticated_to_facebook, :only => [ :edit_facebook,
:sync_facebook_friends]

...before rails even gets to my edit_facebook action the exception is thrown. 

What is the intention of the verify_signature method? It does not make sense to
me outright

I think I saw this, and the problem was the post-add URL defined in the FB
app page needs to go to a controller action that skips the
ensure_facebook_application_is_installed filter.

[Facebooker-talk] Facebooker::Session::IncorrectSignature exception when adding application

This method makes sure requests are actually coming from Facebook.

Without it, anybody could send requests to your application pretending  
to be from any user.

[Facebooker-talk] Facebooker::Session::IncorrectSignature exception when adding application

I have been digging a bit more and I think that I know why this is happening.
Since I am only asking Facebooker to authenticate my current session with
Facebook, I am not getting the expected fb_sig_* parameters from my callback
URL. Instead I only get auth_token and therefore the verify_signature method
fails.

Apparently Facebooker expects ensure_application_is_installed_by_facebook_user
before anything happens, and the callback from that provides fb_sig_* stuff.

I believe I have 3 options:
1) Continue without the signature verification
2) Create a canvas page in my rails app to handle this and leave it blank or
make it link back to my site.
3) Use fb connect - where is this code available?

Thoughts?

What kind of application is this? Facebook should always send the  
fb_sig parameters, right? Is this an iframe application?

[Facebooker-talk] Facebooker::Session::IncorrectSignature exception when adding application

As a heads up.. this could be caused by the change I made that swapped
auth_token auth and fb_sig auth.

[Facebooker-talk] Facebooker::Session::IncorrectSignature exception when adding application

What version did you make the change on ? I can''t seem to find it in
the git history

As a heads up.. this could be caused by the change I made that swapped
auth_token auth and fb_sig auth.

What kind of application is this? Facebook should always send the fb_sig
parameters, right? Is this an iframe application?

I have been digging a bit more and I think that I know why this is happening.
Since I am only asking Facebooker to authenticate my current session with
Facebook, I am not getting the expected fb_sig_* parameters from my callback
URL. Instead I only get auth_token and therefore the verify_signature method
fails.

Apparently Facebooker expects ensure_application_is_installed_by_facebook_user
before anything happens, and the callback from that provides fb_sig_* stuff.

I believe I have 3 options:
1) Continue without the signature verification
2) Create a canvas page in my rails app to handle this and leave it blank or
make it link back to my site.
3) Use fb connect - where is this code available?

Thoughts?

This method makes sure requests are actually coming from Facebook.

Without it, anybody could send requests to your application pretending
to be from any user.
