Yahoo OAuth 1.0 Callback Issue? - ruby-on-rails

Question

I want to use Yahoo Fantasy sport API in my web application, For that I am using OAuth for Yahoo login. I have consumer key and secret key and i passed the keys successfully, When I run the following code. It redirects to Yahoo login, It asks permission for accessing the user's credentials. If i give AGREE the page Redirects to https://api.login.yahoo.com/oauth/v2/request_auth and It shows the Verifying code. If i press the close button in verification code page, it's not callback to my URL.
#ts=Time.now.to_i
#callback_url = "http://localhost:3000/callback"
#nonce = SecureRandom.hex()
consumer = OAuth::Consumer.new("my consumerkey","secret key",
{ :site => 'https://api.login.yahoo.com',
:http_method => :post,
:scheme => :header,
:oauth_nonce => #nonce,
:request_token_path => '/oauth/v2/get_request_token',
:authorize_path => '/oauth/v2/request_auth',
:access_token_path => '/oauth/v2/get_token',
:oauth_callback => "http://localhost:3000/callback",
:oauth_timestamp => Time.now.to_i,
:oauth_signature_method => "HMAC-SHA-1",
:oauth_version => "1.0",
:oauth_callback_confirmed => true,
})
request_token = consumer.get_request_token
session[:request_token]=request_token
redirect_to request_token.authorize_url
access_token=request_token.get_access_token
access = ActiveSupport::JSON.decode(access_token.to_json)
if !(access.present?)
#response = "Response failed"
else
#response = access
end
Can you please tell me What changes to be made to get the callback for to get access_token.

I think you got confused while getting callback. change your code as follows, You will surely get access token to make Yahoo API call.
##access_token = nil
##request_token = nil
def get_request_token
##consumer = OAuth::Consumer.new('consumer key',
'secret key',
{
:site => 'https://api.login.yahoo.com',
:scheme => :query_string,
:http_method => :get,
:request_token_path => '/oauth/v2/get_request_token',
:access_token_path => '/oauth/v2/get_token',
:authorize_path => '/oauth/v2/request_auth'
})
##request_token = ##consumer.get_request_token( { :oauth_callback => 'http://localhost:3000/callback' } )
session[:request_token]=##request_token
redirect_to ##request_token.authorize_url
#redirect_to ##request_token.authorize_url( { :oauth_callback => 'http://localhost:3000/success' } )
end
def callback
request_token = ActiveSupport::JSON.decode(##request_token.to_json)
if !(request_token.present?)
$request_token_value = "Response failed"
else
$request_token_value = request_token
end
# access_token = ##request_token.get_access_token({:oauth_verifier=>params[:oauth_verifier],:oauth_token=>params[:oauth_token]})
##access_token = ##request_token.get_access_token(:oauth_verifier=>params[:oauth_verifier])
access_json = ActiveSupport::JSON.decode(##access_token.to_json)
puts "****************************"
puts $access_json
puts "****************************"
end
