Devise + Omniauth + Carrierwave 不保存 facebook/github 个人资料图片

Question

之前我只使用Omni auth + designise让用户注册。一切都很好。后来我决定使用简单的注册形式设计。我配置了它，它也工作正常，但是当用户想要使用 Omni 身份验证进行注册时会出现问题。Avatar总是设置为nil，即使facebook/Github返回个人资料图片的链接。我已经尝试了这个解决方案，但仍然不起作用，我知道载波远程位置上传方法。我用于 Omni 身份验证的 Gems 是 omniauth-facebook 和 omniauth-github。

User.rb

法典：

class User < ApplicationRecord
  include Storext.model
  devise :database_authenticatable, :registerable, :omniauthable,
     :recoverable, :rememberable, :trackable, :validatable
  validates :first_name, :last_name, :email, :experience_level,
        :goal_level, :theoretical_learner_level, presence: true
  mount_uploader :avatar, AvatarUploader
  # Override devise method for Oauth
  def self.new_with_session(params, session)
    if session['devise.user_attributes']
      new(session['devise.user_attributes'].merge(session[:user_attributes])) do |user|
        user.attributes = params
        user.valid?
      end
    else
      super
    end
  end
  def self.from_omniauth(auth)
    where(auth.slice(:provider, :uid).to_hash).first_or_create do |user|
      OauthUserGenerator.new(user: user, auth: auth).generate
    end
  end
  # If sign in through Oauth, don't require password
  def password_required?
    super && provider.blank?
  end
  # Don't require update with password if Oauth
  def update_with_password(params, *options)
    if encrypted_password.blank?
      update_attributes(params, *options)
    else
      super
    end
  end
end

oauth_user_generator.rb

法典：

class OauthUserGenerator
  def initialize(user:, auth:)
    @user = user
    @auth = auth
  end
  def generate
    @user.provider = @auth.provider
    @user.uid = @auth.uid
    @user.email = @auth.info.email
    @user.password = Devise.friendly_token[0, 20]
    @user.first_name = @auth.info.name.split[0]
    @user.last_name = @auth.info.name.split[1]
    @user.remote_avatar_url = @auth.info.image
  end
end

(三(

omniauth_callbacks_controller.rb

法典：

class OmniauthCallbacksController < Devise::OmniauthCallbacksController
  def omniauth_providers
    process_oauth(request.env['omniauth.auth'].merge(session.fetch(:user_attributes, {})))
  end
  alias facebook omniauth_providers
  alias github omniauth_providers
  private
  def process_oauth(omniauth_params)
    user = User.from_omniauth(omniauth_params)
    if user.persisted?
      flash.notice = 'Signed in!'
      sign_in_and_redirect user
    else
      session['devise.user_attributes'] = user.attributes
      redirect_to new_user_email_registration_path
    end
  end
end

谢谢。

前我遇到了类似的问题。当然，载波不允许从一个协议重定向到另一个协议的remote_url。您通过auth.info.image获得的网址是一个http网址，它会重定向到https网址。所以在你的OauthUserGenerator课上，在你的generate方法上。尝试执行以下操作：

@user.remote_avatar_url = @auth.info.image.gsub('http', 'https')

这样，重定向将来自https -> https。这对我有用。希望这对你来说是同样的问题。
