在我僅使用Omni auth + devise爲用戶註冊之前。一切工作正常。後來我決定使用設計的簡單註冊形式。我配置了它,它也工作正常,但是當用戶想要使用Omni認證註冊時出現問題。即使Facebook/Github正在將鏈接返回到個人資料圖片,但頭像始終設置爲零。我試過這solution但是,仍然不工作,我知道載波遠程位置上傳方法。我用於Omni auth的寶石是omniauth-facebook和omniauth-github。Devise + Omniauth + Carrierwave不保存facebook/github個人資料圖片

User.rb 

代碼:

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 

代碼:

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

omniauth_callbacks_controller.rb 

代碼:

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 

謝謝。

前段時間我有類似的問題。另外,carrierwave不允許remote_url從協議重定向到另一個協議。您通過auth.info.image獲得的網址是http網址,它會重定向到https網址。因此,在您的OauthUserGenerator課程中,您的generate方法中。嘗試執行以下操作:

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

這樣重定向將從https -> https。這對我有效。希望這對你來說也是同樣的問題。
