Rails 4-如何在控制器上正确设置验证操作？

class UsersController < ApplicationController
  before_action :authenticate_user, only: [:edit, :update]

  def edit
    # Edit action logic
  end

  def update
    # Update action logic
  end

  private

  def authenticate_user
    # Authentication logic
    # 如果用户未通过验证，可以使用`redirect_to`方法重定向到其他页面
  end
end

class UsersController < ApplicationController
  before_action :authenticate_user, except: [:index, :show]

  def index
    # Index action logic
  end

  def show
    # Show action logic
  end

  def new
    # New action logic
  end

  def create
    # Create action logic
  end

  private

  def authenticate_user
    # Authentication logic
  end
end

class UsersController < ApplicationController
  before_action :authenticate_user

  def index
    # Index action logic
  end

  def show
    # Show action logic
  end

  def new
    # New action logic
  end

  def create
    # Create action logic
  end

  private

  def authenticate_user
    # Authentication logic
  end

  def skip_authentication
    skip_before_action :authenticate_user, only: [:index, :show]
  end
end
