你不需要有2个重定向uris,你只需要在接收回调时做更多的工作。例如:
class SessionsController < ApplicationController
...
def create
email = auth_hash['info']['email'] # assuming your omniauth hash is auth_hash and you're requiring the email scope
@user = User.find_by(email: email) if !email.blank? # assuming your user model is User
if @user
login_user(@user) # use your login method
elsif !email.blank?
@user = User.new(name: auth_hash['info']['name'], email: email)
unless @user.save!(validate: false) # validate false because I'm enforcing passwords on devise - hence I need to allow passwordless register here)
# deal with error on saving
end
else
# deal with no found user and no email
end
end
protected
def auth_hash
request.env['omniauth.auth']
end
end
我写的所有步骤,但创建过程可以缩短为:
@user = User.create_with(name: auth_hash['info']['name']).find_or_initialize_by(email: email)
@user.save! if @user.new_record?
if @user
login_user(@user)
else
# deal with no user
end
然而,你不能确保用户将会给你范围访问电子邮件,所以我个人认为第一个版本,即使有点更长更强大。然后在较短的版本也有问题,if @user
是错误的,为什么如此?并且需要你添加更多的逻辑来弄清为什么是这样,而在第一种情况下,对每种情况应用正确的响应要容易得多。
