Question

我在某些网站的控制器上使用rails HTTP摘要身份验证。它的工作正常，但是它很快就会超时。

如何调整HTTP摘要验证的超时参数？如何实现HTTP基本身份验证的注销？

谢谢，

如果用户离开网站，或关闭浏览器等，并希望他们保持登录状态：

在你的SessionsController中：

def create
    member = Member.find_by_user_name(params[:user_name])
    if member && member.authenticate(params[:password])
      session[:member_id] = member.id
      if params["remember_me"] == "1"
        cookies[:digest] = {:value => member.password_digest, :expires => Time.now + 720000}
      else
        cookies[:digest] = nil
      end
      redirect_to (url_to_go_to_after_login), :notice => "Logged in!"
    else
      redirect_to (login_url), :alert => "Invalid email or password"
    end
  end

如何注销用户：

  def destroy
    session[:member_id] = nil
    cookies[:digest] = nil
    redirect_to url_to_go_to_after_logout, :notice => "Logged out!"
  end

如何从rememberme cookie登录用户：

  def new
    if member = Member.find_by_password_digest(cookies[:digest])
      session[:member_id] = member.id
      redirect_to (url_to_go_to_after_login), :notice => "Hello#{member.first_name}"
    end
  end

设置以后的过期时间（应在rails＆gt; 2.3 https://github.com/rails/rails/blob/2-3-stable/actionpack/lib/action_controller/session/abstract_store.rb#L175中使用）：

Your::Application.config.session_store :active_record_store, {
  key: "your_session_id",
  domain: ".your-domain.com",
  expire_after: 48.hours,
}
