使用Mailgun和Rails处理传入的电子邮件

标签： ruby-on-rails email parsing mailgun incoming-mail

我正在尝试使用rails和ruby on rails接收传入电子邮件以获取参数并从中解析出正确的数据以创建书签。 Mailgun正在成功处理传入的电子邮件，但rails并未创建书签。你能帮我找一下这个bug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

我使用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

我使用以下信息发送示例电子邮件：

转到：postmaster@appd5fb3842ce6a4e52a5acb511e854e06b.mailgun.org

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，然后在发送示例电子邮件后检查日志：

经过几个小时的努力解决这个问题，这个问题的答案非常简单。

添加到incominig_controller.rb：

skip_before_action :authenticate_user!, only: [:create]

当用户发送电子邮件时，错误即将发生，应用程序希望用户登录（显然不应该是这样）。
