使用 Webhook 和 Mandrill Ruby 的入站电子邮件

Question

根据文档，我们应该查看一个名为“message”的参数，它没有进来。进来的是一个名为“mandrill_events”的参数。

require 'mail'

class InboxController < ApplicationController
  skip_before_filter :verify_authenticity_token, only: :create

  def create
    mail = Mail.new(params[:message])
....

没有骰子，但是当我使用以下语法时，我确实在控制台日志中看到了这一点（注意，JSON 太多以至于无法通过格式查看它）：

puts JSON.parse(params[:mandrill_events])

所以我得到了一个 JSON 字符串，但是获取 TO、FROM 和 SUBJECT 的最佳方法究竟是什么？

更新：我刚刚尝试了以下方法：

tester =  JSON.parse(params[:mandrill_events])

puts tester[:msg][:subject]

#and even this

puts tester["msg"]["subject"]

没有用。出现错误：**TypeError（没有将 String 隐式转换为 Integer）：**

Answer 1

经过一天的努力，我想出了解决方案。顺便说一句，直接访问这些值是行不通的。我不得不循环进入它。

incomingMail = params[:mandrill_events]

mail_from = "Cannot read From"
mail_originally_to = "Cannot read To"
mail_subject = "No subject"
mail_date = ""
mail_body = "No email body"

if incomingMail != nil
  incomingMail = JSON.parse(incomingMail)

  incomingMail.each do |item|
    mail_from = item["msg"]["from_email"]
    mail_originally_to = item["msg"]["headers"]["To"]
    mail_subject = item["msg"]["subject"]
    mail_date = item["msg"]["headers"]["Date"]
    mail_body = item["msg"]["text"]
    mail_body_html = item["msg"]["html"]
  end

  #Confirm
else
  puts "Email not sent. Parameter invalid."
end
