Facebook 连接 - 参数 app_id 是必需的
Facebook Connect - The parameter app_id is required
我尝试在我的网站 ChercheAvocat (Rails 3) 上安装 FB Connect，但是在点击 link "Sign in with Facebook" 之后我有一个错误“参数 app_id 是必须的”。
URL :https://www.facebook.com/dialog/oauth?client_id=&display=popup&redirect_uri=http%3A%2F%2Flocalhost%3A3000%2Fcustomers%2Fauth%2Ffacebook%2Fcallback&response_type=code&scope=email&state=fbe0db878d8d47b896aa18f40e00d5f1e117dde9bef55de9
我在 Developers.Facebook 上创建了应用程序 (Chercheavocat-login)，并将 ID 添加到代码中。
你能帮帮我吗？

OmniAuth 生成的用于使用 Facebook 登录的 URL 中没有 app_id 参数。
您的应用配置是否正确？
你应该在你的 Devise 初始值设定项中有一个关于 OmniAuth 的特定行，比如：
config.omniauth :facebook, "APP_ID", "APP_SECRET"
APP_ID 和 APP_SECRET 可以在您创建的 Facebook 应用程序的详细信息页面中找到。再次强调，将它们保密。您不应将它们直接放入代码中，而应使用 Figaro gem 和环境变量。
有关使用 Devise 实施 OmniAuth Facebook 的完整详细信息，请参见：https://github.com/plataformatec/devise/wiki/OmniAuth:-Overview
更新
所以这实际上已经完成了，但是您是否验证了这些环境变量是否真的设置为正确的值？
我看到你 运行 你的服务器在本地主机上，假设是开发环境；您是否已将这些环境变量添加到您的环境中？
