ruby-on-rails – Rails：Omniauth：Github提供商不太合适

我最近分叉了 https://github.com/fortuity/rails3-mongoid-omniauth并试图让登录为不同的提供商工作.它适用于Twitter和Facebook(你可以在 http://jgodse-omniauth-mongoid.heroku.com/试用),但我无法让它为Github工作.代码快照是 here at github.

我的环境看起来像这样：

$heroku info
=== jgodse-omniauth-mongoid
Web URL:        http://jgodse-omniauth-mongoid.heroku.com/
Git Repo:       git@heroku.com:jgodse-omniauth-mongoid.git
Dynos:          1
Workers:        0
Repo size:      7M
Slug size:      5M
Stack:          bamboo-mri-1.9.2
Data size:      (empty)
Addons:         Basic Logging,MongoHQ MongoHQ Free,Shared Database 5MB
Owner:          xxxxx@yyy.com

Jay@JAY-PC ~/rapps/rails3-mongoid-omniauth (master)
$heroku config --long
BUNDLE_WITHOUT      => development:test
DATABASE_URL        => postgres://xxxxxxxxxxxxxxxxxxxx.compute-1.amazonaws.com/rrretnhwhj
FACEBOOK_APP_ID     => xxxxxxxxxxxxxxxxxxxx
FACEBOOK_APP_SECRET => xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
GITHUB_CLIENT_ID    => xxxxxxxxxxxxxxxxxxxxx
GITHUB_SECRET       => xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

MONGOHQ_URL         => mongodb://heroku:9xxxxxxxxxxxxxxxx.mongohq.com:27098/app527030
RACK_ENV            => production
SHARED_DATABASE_URL => postgres://xxxxxxxxxxxxxxxxxxxxx.compute-1.amazonaws.com/rrretnhwhj
TWITTER_KEY         => xxxxxxxxxxxxxxxxxxx
TWITTER_SECRET      => xxxxxxxxxxxxxxxxxxxxxxxxxxxx

我关于“??OAuth应用程序：Jay的Rails3 Mongoid OAuth”的github信息如下(来自我的应用程序个人资料页面)：

Authorization Token:   https://github.com/login/oauth/authorize
Access Token URL:      https://github.com/login/oauth/access_token
URL:     http://jgodse-omniauth-mongoid.heroku.com/
Callback URL:   http://jgodse-omniauth-mongoid.heroku.com/
Client ID: xxxxxxx
Secret:    xxxxxxxxxxxxxxxx

客户端和机密在omniauth.rb中设置为环境变量

验证发生,但它重定向到http://jgodse-omniauth-mongoid.heroku.com/?error=redirect_uri_mismatch,我没有显然登录.如果我将回调URL更改为http://jgodse-omniauth-mongoid.heroku.com/callback,应用程序崩溃.

我错过了什么让github身份验证工作？
