完全按照 gem 的教程进行操作，我似乎仍然遇到了一些问题。我首先单击链接通过 Facebook 注册并重定向到 Facebook。我单击确定并返回我的注册页面。没有创建新用户。如果我尝试再次单击注册链接，它只会在地址栏中刷新页面http://localhost:3000/register#_=_。我究竟做错了什么？

用户模型

devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable, :omniauthable, omniauth_providers: [:facebook]

def self.from_omniauth(auth)
  where(provider: auth.provider, uid: auth.uid).first_or_create do |user|
    user.email = auth.info.email
    user.password = Devise.friendly_token[0,20]
    user.first_name = auth.info.first_name
    user.last_name = auth.info.last_name
  end
end

回调控制器

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
  def facebook
    # You need to implement the method below in your model (e.g. app/models/user.rb)
    @user = User.from_omniauth(request.env["omniauth.auth"])

    if @user.persisted?
      sign_in_and_redirect @user, :event => :authentication #this will throw if @user is not activated
      set_flash_message(:notice, :success, :kind => "Facebook") if is_navigational_format?
    else
      session["devise.facebook_data"] = request.env["omniauth.auth"]
      redirect_to new_user_registration_url
    end
  end
end

控制台代码

将此行添加到 config/initializers/devise.rb

config.omniauth :facebook, "app id", "app secret", scope: 'email', info_fields: 'email'

新版 Facebook API 有变化， 引入 Graph API v2.4

减少默认字段以提高性能：为了帮助提高移动网络连接的性能，我们减少了 API 默认返回的字段数量。您现在应该使用 ?fields=field1,field2 语法来声明您希望 API 返回的所有字段。

如果您正在关注设计的 wiki 页面，则身份验证失败。在 tge 控制器中，如果身份验证失败，它将重定向到注册路径。就像穆罕默德说的，但你现在应该在你的 info_fields 中添加 first_name 和 last_name 所以在 config/initializers/devise.rb 写这个 config.omniauth :facebook, "app id", "app secret", scope: 'email', info_fields: '电子邮件，名字，姓氏'
