google-oauth2 + devise :: service.list_user_labels user_id - 错误 - Google::Apis::ClientError：请求的身份验证范围不足

如何解决google-oauth2 + devise :: service.list_user_labels user_id - 错误 - Google::Apis::ClientError：请求的身份验证范围不足

错误 - Google::Apis::ClientError: insufficientPermissions: Request had insufficient authentication scopes.

面临错误 - 在dashboards_controller.rb 中的第 result = service.list_user_labels user_id 行

以下是我的文件。

设计.rb

config.omniauth :google_oauth2,client_id,client_secret

users/omniauth_callbacks_controller.rb

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
  def google_oauth2
    #create user

    if user.present?
      flash[:success] = t 'devise.omniauth_callbacks.success',kind: 'Google'
      sign_in_and_redirect user,event: :authentication
    else
      flash[:alert] = t 'devise.omniauth_callbacks.failure',kind: 'Google',reason: "#{auth.info.email} is not authorized."
      redirect_to new_user_session_path
    end
  end
end

dashboards_controller.rb

require 'google/api_client/client_secrets.rb'

        # Initialize the API
        service = Google::Apis::GmailV1::GmailService.new
        service.authorization = google_secret.to_authorization
        service.authorization.refresh!
        # Show the user's labels
        user_id = current_user.uid
        result = service.list_user_labels user_id
        puts "Labels:"
        #puts "No labels found" if result.labels.empty?
        #result.labels.each { |label| puts "- #{label.name}" }
  end

      def google_secret
            scope = "https://www.googleapis.com/auth/gmail.labels"

            Google::APIClient::ClientSecrets.new(
          { "web" =>
            { "access_token" => current_user.token,"refresh_token" => current_user.refresh_token,"client_id" => client_id,"client_secret" => client_secret,"scope" => scope
