第三方服务集成

Question

我正在处理我的应用中的电子邮件回复功能，我正在使用 mandrillapp.com。现在如何运作：

1. User replies from their email to something@something.com
2. Mandril receives the mail and sends the POST request to preconfigured endpoint of my service
3. I process that post request (create internal app message)

关于第 3 步，我的基本代码应该创建包装在 begin/rescue 中的内部应用程序消息。所以任何潜在的错误都会被报告给我，他们过去也有过。

但是现在我遇到了一个用户声称电子邮件已经发送（第 1 步），我联系了 mandrill 支持，他们说他们已经处理并发送到我的端点（第 2 步）。

因此，我只能在特定时间范围内查看第 3 步中发生了什么。我的应用程序在 heroku 上，我的日志存储在 AWS 上，我可以回到过去的那个特定时间，我可以看到来自 mandrill 端的成功 POST 请求。

我能做些什么来赶上这个案子？当然要修复它，因为我不知道现在发生了什么。

我正在考虑创建一个名为 Mandrill hooks 的模型，它的 params 列将是一个序列化的哈希，它将保存从 mandrill 到达我的端点的所有参数。

然后我可以检查我的帐户收到的 webhook 的计数和 mandrill 发送的 webhook 的计数，希望我发现 1 具有不同的计数，并且由于我的数据库中有参数数据，我将能够重现案例。

还是有更明智的方法，因为这在我看来也很幼稚？

我认为可能有一种更明智的方法可以让您更好地控制一切，这听起来与我最近完成的和I answered a similar question here 非常相似。这是否有帮助，还是您想要一些更具体的帮助？

** 编辑：下面链接的帖子/代码

我在 VS 中将 Mandrill Webhook 处理作为 API 项目运行，这就是我启动和运行它的方式：

    [HttpPost]
    public string Post()
    {
        /* Every Mandrill webhook uses the same general data format, regardless of the event type. 
         * The webhook request is a standard POST request with a single parameter (currently) - 'mandrill_events'. */

        string validJson = HttpContext.Current.Request.Form["mandrill_events"].Replace("mandrill_events=", ""); //"mandrill_events=" is not valid JSON. If you take that out you should be able to parse it. //http://stackoverflow.com/questions/24521326/deserializing-mandrillapp-webhook-response
        List<MandrillEvent> mandrillEventList = JsonConvert.DeserializeObject<List<MandrillEvent>>(validJson);

        foreach (MandrillEvent mandrillEvent in mandrillEventList)
        {
            if (mandrillEvent.msg.email != null)
            {
                DataLayer.ReportingData.EmailSave(mandrillEvent); //Saves MandrillEvent email to database and sets a messageId for datalayer
            }
        } 

        foreach (MandrillEvent mandrillEvent in mandrillEventList)
        {
            DataLayer.ReportingData.MandrillEventSave(mandrillEvent); //Saves MandrillEvent object to database
        }

        return "DONE";
    }

然后，我使用“mandrill_event”的记录（和未记录）JSON 参数并使用json2csharp.com 生成C# 属性。我创建了一个名为“MandrillEvent.cs”的类并将它们放在：

public class SmtpEvent
    {
        public int ts { get; set; }
        public DateTime SmtpTs { get; set; }
        public string type { get; set; }
        public string diag { get; set; }
        public string source_ip { get; set; }
        public string destination_ip { get; set; }
        public int size { get; set; }
        public int smtpId { get; set; } //added for datalayer
    }

    public class Msg
    {
        public int ts { get; set; }
        public DateTime MsgTs { get; set; }
        public string _id { get; set; }
        public string state { get; set; }
        public string subject { get; set; }
        public string email { get; set; }
        public List<object> tags { get; set; }
        public List<object> opens { get; set; } //an array of containing an item for each time the message was opened. Each open includes the following keys: "ts", "ip", "location", "ua"
        public List<object> clicks { get; set; } //an array containing an item for each click recorded for the message. Each item contains the following: "ts", "url"
        public List<SmtpEvent> smtp_events { get; set; }
        public List<object> resends { get; set; } //not currently documented on http://help.mandrill.com/entries/58303976-Message-Event-Webhook-format
        public string _version { get; set; }
        public string diag { get; set; } //for bounced and soft-bounced messages, provides the specific SMTP response code and bounce description, if any, received from the remote server
        public int bgtools_code { get; set; } //Is it this? for bounced and soft-bounced messages, a short description of the bounce reason such as bad_mailbox or invalid_domain. (not currently documented but in JSON response)
        public string sender { get; set; }
        public object template { get; set; }
        public string bounce_description { get; set; }

        public Msg()
        {
            tags = new List<object>();
            opens = new List<object>();
            clicks = new List<object>();
            smtp_events = new List<SmtpEvent>();
            smtp_events.Add(new SmtpEvent());
            resends = new List<object>();
        }
    }

    public class MandrillEvent
    {
        public string @event { get; set; }
        public string _id { get; set; }
        public Msg msg { get; set; }
        public int ts { get; set; }
        public DateTime MandrillEventTs { get; set; }
        public int messageId { get; set; } //added for datalayer
        public List<string> SingleMandrillEventData { get; set; } //added for Reporting

        public MandrillEvent()
        {
            SingleMandrillEventData = new List<string>();
            msg = new Msg();
        }
    }

您现在将“mandrill_events”JSON 对象作为功能 C# 对象！这是帮助还是您需要更多说明/帮助？
