使用Mailgun和Rails处理传入电子邮件

Question

我正在尝试使用malil和ruby on rails获取params并解析其中的正确数据以创建书签。Mailgun正在成功处理传入的电子邮件，但rails没有创建书签。你能帮我找到虫子吗？

我在routes.rb 中添加了一个POST

post :incoming, to: 'incoming#create'

Rails.application.routes.draw do
  post :incoming, to: 'incoming#create'
  resources :topics do
    resources :bookmarks, except: [:index]
  end
  devise_for :users
  get 'about' => 'welcome#about'
  root 'welcome#index'
end

我用create方法创建了incoming_controller.rb。

class IncomingController < ApplicationController
  skip_before_action :verify_authenticity_token, only: [:create]
  def create
     user = User.find(params[:sender])
     topic = Topic.find(params[:subject])
     url = params["body-plain"]
     if @user.nil?
       @user = User.new(email: user, password: "password")
       @user.save!
     end
      if @topic.nil?
        @topic = Topic.new(title: topic)
        @topic.save!
      end
      @bookmark = @topic.bookmarks.build(user: user, url: url)
      @bookmark.save!

    head 200
  end
end

我发送了一封样本电子邮件，其中包含以下信息：

到：[e-mail]

主题：Ruby on Rails

正文：www.amazon.com

Mailgun成功处理传入的电子邮件。该应用程序部署在heroku中，然后我在发送示例电子邮件后查看日志：

Answer 1

经过数小时与这个bug的斗争，这个问题的答案很简单。

添加到incominig_controller.rb:

skip_before_action :authenticate_user!, only: [:create]

当用户发送电子邮件时出现错误，应用程序希望该用户登录（显然不应该是这样）。
