ruby-on-rails - Ruby omniauth-oauth2 - A Errno::ENETUNREACH - 网络无法访问 - 连接(2)

Question

当用户尝试使用 facebook 登录时，我的 Rails 应用程序有时(大约 2 周后)在回调方法期间崩溃。

这是随机发生的，我找不到解决这个问题的方法。

下面是错误和一段堆栈跟踪:

Errno::ENETUNREACH 发生在#:网络无法访问 - connect(2)

• REQUEST_METHOD:获取
• REQUEST_PATH :/auth/facebook/callback
• REQUEST_URI :/auth/facebook/callback?code=AQDoUnHaO4ShfZUtCw6TVHAd_oOWUQ7Lar-OunhlFHoWhpTmiliY8hWTEb0CmufEMABpUggIlAe15jx8BOxTmVXmHb3JvVlePEfECpkVhf82UWdoHK8jCYN00KM5RYUkbx6M5SHjusb2xWFeHnE92-nfvbpw2KSARqR5njgJqbV_hkJYb42SiuvNXKOTU6hYY_g

Answer 1

这听起来像是需要向我重新请求访问 token ，但这是一个不为人知的猜测。

在我让它工作之前，有很多事情阻止了回调对我的工作:

• 互联网连接全部停止
• config/routes 中没有路由
• 糟糕的javascript
• 回调 url 与 facebook 应用程序不匹配
• oauth 的过时版本..等..

请随时仔细检查您的工作和我的工作，看看是否有帮助:
