使用 omniauth-facebook 登錄 facebook 時執行過期錯誤

Question

自 7 月 3 日起，用戶無法從 Facebook 登錄。 我正在使用 omniauth-facebook。 我從本地主機成功測試登錄（指向另一個 FB 測試應用程序）。 但在生產中，應用程序顯示此錯誤：

我嘗試使用 localhost 使用 Facebook 創建一個測試應用程序，它可以工作。 我嘗試使用另一個域生產的另一個應用程序，它可以工作。 它不適用於生產中的此特定應用程序。 我給 Facebook 支持發了消息，但他們沒有回復，幾天過去了。

我正在使用 RoR 4.2.8 和 Bundler 1.17.3 我嘗試使用 ruby​​-2.5.1 和 ruby​​-2.3.3 以防萬一（同樣的錯誤）

我嘗試使用另一個具有相同設置的 Facebook 應用程序，使用另一個帶有 ruby​​-2.6 的 RoR v5 應用程序並且它工作正常，所以 FB 應用程序設置似乎沒問題。

我創建了另一個 FB 應用程序，以嘗試使用失敗的 RoR v4.2.8 應用程序，但它以相同的“Faraday::ConnectionFailed (execution expired):”錯誤失敗。

配置/初始化程序/omniauth.rb

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :facebook, 'APP-ID', 'SECRET',
    scope: 'email'
end

用戶應該可以使用 Facebook 登錄，但失敗並顯示“Faraday::ConnectionFailed（執行已過期）：”

Answer 1

從表面上看，您遇到了網絡問題，其中法拉第沒有設置為等待足夠長的響應時間。 我從跟蹤中真正能看出的是，在通往 facebook 和返回的路上的某個地方，您遇到了網絡問題。

我可以考慮檢查幾件事：

• 如果您的站點通過 HTTPS 運行，請確保您的證書正常工作。
  • 檢查您的 gemfile 是否設置為需要與您的 Rails 版本和依賴項兼容的omniauth-facebook的特定版本。
  • 延長法拉第的超時時間
  • 使用像https://github.com/ooyala/retries這樣的重試 gem 嘗試給網絡足夠的時間在法拉第關閉連接之前做出響應。
