使用全真身份验证脸书登录时执行过期错误

Question

自7月3日起，用户无法从Facebook登录。 我正在使用omniauth-facebook。我测试了从本地主机成功登录(指向另一个FB测试应用程序)。但在生产环境中，应用程序会显示此错误：

我尝试使用本地主机与Facebook创建一个测试应用程序，它可以工作。 我尝试使用另一个域的生产中的另一个应用程序，它可以工作。 它不适用于生产中的此特定应用程序。我给Facebook的支持发了消息，但他们没有回复，几天过去了。

我正在使用 RoR 4.2.8，捆绑器 1.17.3 我尝试使用 ruby-2.5.1 和 ruby-2.3.3 以防万一(同样的错误)

我尝试使用另一个具有相同设置的 Facebook 应用程序，使用另一个带有 ruby-5 的 RoR v2.6 应用程序并且它有效，因此 FB 应用程序设置似乎还可以。

我创建了另一个FB应用程序，以尝试使用失败的RoR v4.2.8应用程序，它失败并出现相同的"法拉第：：连接失败(执行已过期)："错误。

config/initializers/omniauth.rb

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

用户应该能够使用Facebook登录，但它失败并显示"Faraday：：ConnectionFailed(执行已过期)：">

Answer 1

从表面上看，您遇到了一个网络问题，法拉第没有设置为等待足够长的响应时间。我从跟踪中真正能看出的是，沿着通往Facebook和返回的小径的某个地方，您遇到了网络问题。

我可以想到的几件事来检查：

• 如果您的站点通过 HTTPS 运行，请确保您的证书正常工作。
  • 检查您的 gemfile 是否设置为需要与您的 Rails 版本和依赖项兼容的特定omniauth-facebook版本。
  • 延长法拉第的超时长度
  • 使用像 https://github.com/ooyala/retries 这样的重试 gem 来尝试在 Faraday 关闭连接之前给网络足够的时间来响应。

其他一些人在omniauth-facebook的github https://github.com/mkdynamic/omniauth-facebook/issues/283 中对这个问题发表了评论。
