我是 Rails 的新手,我正在尝试将omniauth 和登录与谷歌集成。在网上冲浪我找到了一种方法,但我收到了这个错误:
undefined method `[]' for nil:NilClass
app/models/user.rb:22:in `find_for_open_id'
app/controllers/users/omniauth_callbacks_controller.rb:17:in `open_id'
我认为这是因为我没有正确访问访问令牌信息。
这是代码:
模型用户.rb
def self.find_for_open_id(access_token, signed_in_resource=nil)
data = access_token['user_info']
if user = User.find_by_email(data["email"])
user
else # Create a user with a stub password.
User.create!(:email => data["email"], :password => Devise.friendly_token[0,20])
end
end
omniauth_callbacks_controller.rb
def open_id
# You need to implement the method below in your model
@user = User.find_for_open_id(env["omniauth.auth"], current_user)
if @user.persisted?
flash[:notice] = I18n.t "devise.omniauth_callbacks.success", :kind => "Google"
sign_in_and_redirect @user, :event => :authentication
else
session["devise.open:id_data"] = env["openid.ext1"]
redirect_to new_user_registration_url
end
end
设计.rb
config.omniauth :open_id, :store => OpenID::Store::Filesystem.new("/tmp"), :name => 'open_id', :identifier => 'https://www.google.com/accounts/o8/id'
我不知道我还能给你看什么。
对我来说,问题就在这里:
数据 = access_token['user_info']
access_token['user_info'] 返回空值。
难道我做错了什么?还有其他方法可以访问“user_info”然后访问电子邮件吗?
提前致谢。希望我很清楚。
