我尝试在我的网站ChercheAvocat（Rails 3）上安装FB Connect，但点击链接后＃34;使用Facebook登录＆＃34;我有一个错误＆＃34;参数app_id是必需的＆＃34;。 网址：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），我已将ID添加到代码中。
你能帮助我吗？

答案 0 :(得分：1)
OmniAuth通过Facebook登录时，网址中没有app_id参数。
您是否正确配置了应用？ 你的Devise初始化程序中应该有一个关于OmniAuth的特定行，如：
config.omniauth :facebook, "APP_ID", "APP_SECRET"
APP_ID和APP_SECRET位于您创建的Facebook应用的详细信息页面中。再一次，将它们保密。您不应将它们直接放在代码中，而应使用Figaro gem和环境变量。
有关使用Devise实施OmniAuth Facebook的详细信息，请访问：https://github.com/plataformatec/devise/wiki/OmniAuth:-Overview
<强>更新
事实上这已经完成了，但是你确认这些环境变量确实设置为正确的值吗？
我看到你在localhost上运行你的服务器，假设一个开发环境;你有没有将这些环境变量添加到你的环境中？
