我对 RoR 比较陌生，最近建立了一个有效的linkedin 自动化。
我的linkedin OmniAuth 连接似乎已断开。它工作了大约 12 个小时。但是，我的代码库没有改变，但我现在收到以下错误。
OAuth::Problem
parameter_absent
使用 rails 3、gem 'omniauth'、gem 'omniauth-linkedin'
我已经通过这些链接无济于事： https ://github.com/intridea/omniauth/issues/622 OAuth::Problem (parameter_absent) Rails - OAuth::Problem Exception: parameter_absent in LinkedIn API
这是完整的跟踪
