我创建了新的Rails应用程序并安装了Devise和omniauth-facebook gem.

并将我的Facebook App设置为测试环境.

所以,我通过Facebook登录并注册了我的新Rails应用程序,但request.env不包含电子邮件地址.info.

返回request.env ['omniauth.auth']

{
   "provider" => "facebook",
   "uid" => "xxxxxxxxxxxx",
   "info" => {
         "name" => "xxxxxxx",
        "image" => "http://graph.facebook.com/xxx/picture"
    },
    "credentials" => {
             "token" => "tokenstring",
        "expires_at" => xxxxxxxxx,
           "expires" => true
    },
          "extra" => {
        "raw_info" => {
            "name" => "xxx xxxx",
              "id" => "xxxxxxxxx"
        }
    }
}

它机架request.env ['omniauth.auth'] ['info'] ['email']

如何通过oauth从facebook获取电子邮件地址？请有人帮帮我.

Rails ver是4.2.3 Ruby ver是2.2.2p95

这是宝石版本

 omniauth (1.2.2)
 omniauth-facebook (2.0.1)
 devise (3.5.1)

配置/初始化/ devise.rb

  config.omniauth :facebook, 'appId', 'appSeacret', scope: 'email,public_profile'

应用程序/控制器/ omniauth_callbacks_controller.rb

  def …

我有Order模型并Order.all在下面返回.
