Question

尝试创建用户时，我在开发过程中遇到此错误。谁能告诉我我做错了什么？

users_controller.rb

  def create
    @user = User.new(user_params)
    if @user.save
      session[:user_id] = @user.id
      UserMailer.signup_confirmation(@user).deliver_now
      redirect_to user_tasks_path(current_user.id), notice: "Thank you for signing up!"
    else
      render "new"
    end
  end

环境/ development.rb

Rails.application.configure do
  # Settings specified here will take precedence over those in config/application.rb.

  # In the development environment your application's code is reloaded on
  # every request. This slows down response time but is perfect for development
  # since you don't have to restart the web server when you make code changes.

  config.eager_load = false

  # Show full error reports and disable caching.

  }

尝试传递邮件时，gmail会拒绝连接。我有几乎相同的问题，最近我发现我没有在我的系统上启用ping gmail的telnet客户端。所以我在我的系统上启用了telnet客户端（Windows 7）。还要运行telnet测试来排除连接故障。我已按照此链接[http://techblissonline.com/troubleshoot-gmail-smtp-server-connection/]http://techblissonline.com/troubleshoot-gmail-smtp-server-connection/进行telnet测试。如果您能够ping gmail并且仍然收到错误，那么请转到gmail设置并允许安全性较低的应用访问您的帐户。
