Dynamics 365利用email实体的DeliverIncomingEmail来做抓取邮件的进一步处理

其他 2020-07-26 19:58:27 阅读次数: 0

我是微软Dynamics 365 & Power Platform方面的工程师罗勇，也是2015年7月到2018年6月连续三年Dynamics CRM/Business Solutions方面的微软最有价值专家(Microsoft MVP)，欢迎关注我的微信公众号 MSFTDynamics365erLuoYong ，回复421或者20200726可方便获取本文，同时可以在第一间得到我发布的最新博文信息，follow me!

关于这个消息的官方文档请参考 DeliverIncomingEmail Action 。

为了方便测试，我建立一个public queue，如下：

 为Queue的mailbox执行Approve Email 和 Test & Enable Mailbox 后确保其Incoming Email Status 和 Outgoing Email Status 都是Success 。

 然后我撰写了一个插件，代码如下，

using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Sdk.Query;
using System;

namespace DemoPlugins
{
    public class EmailDeliverIncomingPostPlugin : IPlugin
    {
        public void Execute(IServiceProvider serviceProvider)
        {
            ITracingService tracingService = (ITracingService)serviceProvider.GetService(typeof(ITracingService));
            tracingService.Trace($"Enter {this.GetType()} on {DateTime.UtcNow.ToString("yyyy-MM-dd HH:mm:ss:ms")}");
            IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
            tracingService.Trace($"context.UserId = {context.UserId}");
            tracingService.Trace($"context.InitiatingUserId = {context.InitiatingUserId}");
            if (context.InputParameters.Contains("ExtraProperties") && context.InputParameters["ExtraProperties"] is Entity)
            {
                tracingService.Trace("InputParameters contains ExtraProperties and ExtraProperties is Entity.");
                var currentEntity = (Entity)context.InputParameters["ExtraProperties"];
                tracingService.Trace($"ExtraProperties Entity Logical Name = { currentEntity.LogicalName},Entity Id = { currentEntity.Id }");
                foreach (var item in currentEntity.Attributes)
                {
                    if (item.Value != null)
                    {
                        tracingService.Trace($"ExtraProperties attribute key = {item.Key} value = {item.Value.ToString()} type = { item.Value.GetType()}");
                    }
                    else
                    {
                        tracingService.Trace($"ExtraProperties attribute key = {item.Key} value = null");
                    }
                }
            }
            else
            {
                tracingService.Trace("InputParameters does not contain ExtraProperties or ExtraProperties are not Entity.");
            }
            int i = 1;
            if (context.InputParameters.Contains("Attachments") && context.InputParameters["Attachments"] is EntityCollection)
            {
                tracingService.Trace("InputParameters contains Attachments and Attachments is EntityCollection.");
                var ec = (EntityCollection)context.InputParameters["Attachments"];
                foreach (var ecEntity in ec.Entities)
                {
                    tracingService.Trace($"Attachment - {i},Entity Logical Name = {ecEntity.LogicalName},Entity Id ={ecEntity.Id}");
                    foreach (var item in ecEntity.Attributes)
                    {
                        if (item.Value != null)
                        {
                            if (item.Value.ToString().Length >= 210)
                            {
                                tracingService.Trace($"Attachments attribute key = {item.Key} value = {item.Value.ToString().Substring(0, 200)} type = { item.Value.GetType()}");
                            }
                            else
                            {
                                tracingService.Trace($"Attachments attribute key = {item.Key} value = {item.Value.ToString()} type = { item.Value.GetType()}");
                            }
                        }
                        else
                        {
                            tracingService.Trace($"Attachments attribute key = {item.Key} value = null type = { item.Value.GetType()}");
                        }
                    }
                    i++;
                }
            }
            else
            {
                tracingService.Trace("InputParameters does not contain Attachments or Attachments are not EntityCollection.");
            }
        }
    }
}

我将其注册到email实体的DeliverIncoming 消息的PostOperation阶段，为了减少影响，我将Execution Mode设置为Asynchronous .

然后我往往这个queue发一封没有附件的邮件，打开Plug-in Trace Log产生的日志如下，这个User是 SYSTEM　账号。

Enter DemoPlugins.EmailDeliverIncomingPostPlugin on 2020-07-26 09:46:44:4644

ExtraProperties attribute key = followemailuserpreference value = False type = System.Boolean
ExtraProperties attribute key = correlationmethod value = 0 type = System.Int32
InputParameters contains Attachments and Attachments is EntityCollection.

发一份有附件的邮件，日志如下：

如果是答复邮件被抓取有啥不一样，我先通过LuoYong Test Queue往我的邮箱发一封邮件，这个邮件与一个订单做了关联，然后我回复邮件，我们通过日志来看：

1. ExtraProperties参数增加了属性 parentactivityid ，类型为Guid，这个值是答复邮件的Guid，有了这个就可以知道邮件是关于那个实体记录，获取关联的实体记录的详细信息。

2. ExtraProperties参数增加了属性 inreplyto ，类型为string，值类似这种 0C27DF54E5964AD88C8EB1A4B0F0576E1D66334DB9AC@LUOYONGMAILFORQUEUE.CRM435740.ONMICROSOFT.COM ，我也不知道用处。

那下面我们做点增强，如果答复的邮件是关于 ly_order 实体记录的话(能知道关联的是哪条记录当然你就可以做得更多)，我就创建一个新邮件，将收到的邮件的附件发送给我的邮箱 [email protected] 。

请注意，我这里利用了仅限内部使用的参数 ExtraProperties ，参数中的内容有可能变化而不通知，各位谨慎使用。

    }
}

看我收到了自动转发过来的邮件：

 你可能会问，还能获取其他信息，当然还包括其他信息，比如收件人，邮件标题，邮件内容，发件人，收到邮件的时间等，可以通过官方文档看到包括那些，代码可以通过这样来看下：

            foreach(var item in context.InputParameters)
            {
                if (item.Value != null)
                {
                    tracingService.Trace($"InputParameters key = {item.Key} value = {item.Value.ToString()} type = { item.Value.GetType()}");
                }
                else
                {
                    tracingService.Trace($"InputParameters key = {item.Key} value = null");
                }
            }

我这里提供一个参数值示例，可以看到From的值不只是邮箱，具体情况具体查看。

InputParameters key = MessageId value = <FR1P152MB07091928254D8482F3F57DEE88750@FR1P152MB0709.LAMP152.PROD.OUTLOOK.COM> type = System.String

InputParameters key = ReceivedOn value = 7/26/2020 11:16:14 AM type = System.DateTime
InputParameters key = SubmittedBy value = "罗 勇" [email protected] type = System.String
InputParameters key = Importance value = 1 type = System.String
InputParameters key = Body value = body type = System.String
InputParameters key = Attachments value = Microsoft.Xrm.Sdk.EntityCollection type = Microsoft.Xrm.Sdk.EntityCollection
InputParameters key = Subject value = 回复: LuoYong Test Queue给你发一封邮件 CRM:0001001 type = System.String
InputParameters key = ValidateBeforeCreate value = True type = System.Boolean
InputParameters key = ExtraProperties value = Microsoft.Xrm.Sdk.Entity type = Microsoft.Xrm.Sdk.Entity
