参考resume的代码进行设置

#config/initializer/omniauth.rb
Rails.application.config.middleware.use OmniAuth::Builder do
  provider :github, Rails.application.credentials.dig(:development, :github_id), 
    Rails.application.credentials.dig(:development, :github_secret)
end

#user.rb
def find_by_omniauth(auth)
  user = User.find_by_provider_and_nickname(auth["provider"], auth["info"]["nickname"])
  user ? user : User.create_with_omniauth(auth)
end

def create_with_omniauth(auth)
  create! do |user|
    random_password = SecureRandom.hex(9)
    user.provider = auth["provider"]
    user.nickname = auth["info"]["nickname"]
    user.password = random_password
    user.password_confirmation = random_password
    user.name_en = auth["info"]["nickname"] + "-" +RandomCode.generate_name_uuid
  end
end

#sessions_controller.rb
def create
  user = User.find_by_omniauth(auth)
  log_in user
  flash[:success] = t('github_login_successfully')
  redirect_to edit_user_path(user)
end

#view
<a href="/auth/github">login</a>
