在Rails中验证Facebook时出现OAuth2错误

Question

在开发模式下,在localhost/auth/facebook的身份验证回调阶段,我遇到以下错误

OAuth2 ::错误:{"access_token":"XXX","token_type":"bearer","expires_in":123}

这是错误的位置

这是堆栈跟踪

oauth2 (0.9.4) lib/oauth2/client.rb:140:in `get_token'
oauth2 (0.9.4) lib/oauth2/strategy/auth_code.rb:29:in `get_token'
omniauth-oauth2 (1.1.2) lib/omniauth/strategies/oauth2.rb:93:in `build_access_token'
omniauth-facebook (1.6.0) lib/omniauth/strategies/facebook.rb:145:in `block in build_access_token'
omniauth-facebook (1.6.0) lib/omniauth/strategies/facebook.rb:171:in `with_authorization_code!'
omniauth-facebook (1.6.0) lib/omniauth/strategies/facebook.rb:145:in `build_access_token'
omniauth-oauth2 (1.1.2) lib/omniauth/strategies/oauth2.rb:75:in `callback_phase'
omniauth-facebook (1.6.0) lib/omniauth/strategies/facebook.rb:71:in `callback_phase'
omniauth (1.4.2) lib/omniauth/strategy.rb:227:in `callback_call'
omniauth (1.4.2) lib/omniauth/strategy.rb:184:in `call!'
omniauth (1.4.2) lib/omniauth/strategy.rb:164:in `call'

我使用以下宝石版本

• oauth(0.5.1)
• oauth2(0.9.4)
• omn​​iauth(1.4.2)
• omn​​iauth-facebook(1.6.0)

我怀疑这是一个问题,宝石与Facebook发回的数据不兼容.

有关如何应对这一挑战的任何指示？

您可能正在使用较旧的宝石版本.如果您的应用程序可行,则更新版本可能是个好主意.另外,请检查您的环境中是否能够与Facebook通信,并且没有代理问题.
