尝试接受照片作为 Microsoft 聊天机器人附件并将其作为电子邮件附件发送 C#

Question

我正在尝试在 Microsoft 聊天机器人 waterFall 对话框中接受照片作为附件...然后将其作为附件或（甚至在正文中）电子邮件功能（我创建的）发送。电子邮件功能似乎可以正常工作....但是我无法在电子邮件中传递照片附件

就像：

无法将 Microsoft bot 架构附件转换为字符串

这是我的代码：第一种方法是要求用户上传照片

  private static async Task<DialogTurnResult> UploadAttachmentAsync(WaterfallStepContext stepContext, CancellationToken cancellationToken)
    {
        stepContext.Values["desc"] = (string)stepContext.Result;
        if (lang == "en")
        {
            lang = "en";
            return await stepContext.PromptAsync(

                attachmentPromptId,
                new PromptOptions
                {
                    Prompt = MessageFactory.Text($"Can you upload a ScreenShot of the Error?"),
                });
        }
        else if (lang == "ar")
        {
            lang = "ar";
            return await stepContext.PromptAsync(

               attachmentPromptId,
               new PromptOptions
               {
                   Prompt = MessageFactory.Text($"هل يمكنك تحميل لقطة شاشة للخطأ؟"),
               });
        }
        else return await stepContext.NextAsync(); 


    }

第二种方法是上传代码本身：

   private async Task<DialogTurnResult> UploadCodeAsync(WaterfallStepContext stepContext, CancellationToken cancellationToken)
    {

         List<Attachment> attachments = (List<Attachment>)stepContext.Result;
         string replyText = string.Empty;
         foreach (var file in attachments)
         {
             // Determine where the file is hosted.
             var remoteFileUrl = file.ContentUrl;

             // Save the attachment to the system temp directory.
             var localFileName = Path.Combine(Path.GetTempPath(), file.Name);

             // Download the actual attachment
             using (var webClient = new WebClient())
             {
                 webClient.DownloadFile(remoteFileUrl, localFileName);
             }

             replyText += $"Attachment \"{file.Name}\"" +
                          $" has been received and saved to \"{localFileName}\"\r\n";
         }

         return await stepContext.NextAsync();                          
    }

第三个是将照片存储为 activity 结果以便稍后传递

  private static async Task<DialogTurnResult> ProcessImageStepAsync(WaterfallStepContext stepContext, CancellationToken cancellationToken)
    {
        stepContext.Values["picture"] = ((IList<Attachment>)stepContext.Result)?.FirstOrDefault();
        await stepContext.PromptAsync(nameof(TextPrompt), new PromptOptions { Prompt = MessageFactory.Text("Attachment Recieved...Thank you!!") }, cancellationToken);
        return await stepContext.EndDialogAsync();
    }

最后是我存储从每个 stepcontext 获得的值并应在电子邮件正文中传递的步骤：（附件应该放在 ticketProfile.screenShot 中）

 private static async Task<DialogTurnResult> SummaryStepAsync(WaterfallStepContext stepContext, CancellationToken cancellationToken)
    {
        var ticketProfile = await _ticketDialogAccessor.GetAsync(stepContext.Context, () => new Ticket(), cancellationToken);

        ticketProfile.userType = (string)stepContext.Values["userType"];
        ticketProfile.staffType = (string)stepContext.Values["staffType"];
        ticketProfile.empIdInfo = (string)stepContext.Values["shareId"];
        ticketProfile.emailInfo = (string)stepContext.Values["shareEmail"];
        ticketProfile.helpType = (string)stepContext.Values["helpType"];
        ticketProfile.describeHelp = (string)stepContext.Values["desc"];
        ticketProfile.screenShot = (Attachment)stepContext.Values["picture"];

        string[] paths = { ".", "adaptiveCard.json" };
        var cardJsonObject = JObject.Parse(File.ReadAllText(Path.Combine(paths)));

        var userEmailValue = cardJsonObject.SelectToken("body[2].facts[0]");
        var userIdValue = cardJsonObject.SelectToken("body[2].facts[1]");
        var userTypeValue = cardJsonObject.SelectToken("body[2].facts[2]");
        var staffTypeValue = cardJsonObject.SelectToken("body[2].facts[3]");
        var helpTypeValue = cardJsonObject.SelectToken("body[2].facts[4]");
        var describeValue = cardJsonObject.SelectToken("body[2].facts[5]");


        userEmailValue["value"] = ticketProfile.emailInfo;
        userIdValue["value"] = ticketProfile.empIdInfo;
        userTypeValue["value"] = ticketProfile.userType;
        staffTypeValue["value"] = ticketProfile.staffType;
        helpTypeValue["value"] = ticketProfile.helpType;
        describeValue["value"] = ticketProfile.describeHelp;


        var attachment = new Attachment()
        {
            Content = cardJsonObject,
            ContentType = "application/vnd.microsoft.card.adaptive"
        };

         var reply = stepContext.Context.Activity.CreateReply();
        reply.Attachments = new List<Attachment>();

        reply.Attachments.Add(attachment);
        await stepContext.Context.SendActivityAsync(reply);
        Email($"Here you go{Environment.NewLine}{ticketProfile.screenShot}");



        return await stepContext.EndDialogAsync(cancellationToken: cancellationToken);
    }

电子邮件功能：

 public static void Email(string htmlString)
    {
        try
        {
            MailMessage mail = new MailMessage();
            SmtpClient SmtpServer = new SmtpClient();
            mail.From = new MailAddress("hassanjarko55@gmail.com");

            mail.Subject = "New Ticket";

            mail.Body = htmlString;
            SmtpServer.Port = 587;
            SmtpServer.Host = "smtp.gmail.com";
            SmtpServer.EnableSsl = true;
            SmtpServer.UseDefaultCredentials = false;
            SmtpServer.Credentials = new NetworkCredential("user Name, "password");
            SmtpServer.DeliveryMethod = SmtpDeliveryMethod.Network;
            mail.To.Add(new MailAddress("hassan.jarko@yahoo.com"));
            mail.IsBodyHtml = true;

            SmtpServer.Send(mail);
        }

        catch (Exception e)
        {

            e.ToString();

        }
    }



 public class Ticket
{
    public string userType { get; set; }

    public string staffType { get; set; }

    public string helpType { get; set; }

    public string helpWith { get; set; }


    public string describeHelp { get; set; }

    public Attachment screenShot { get; set; }

    public string emailInfo { get; set; }

    public string empIdInfo { get; set; }
}

任何帮助将不胜感激...在此先感谢

Answer 1

您是否尝试过附加文件名而不是附加 microsoft.bot.schema.attachment 类型

也看看@这个可能对你有帮助 How do I add an attachment to an email using System.Net.Mail?

同样在您的电子邮件功能中，您需要添加此代码才能在您的电子邮件中添加附件

mail.Attachments.Add(new Attachment());

注意：我对C#没有那么深的了解，但我喜欢参与这类没有答案的问题，以帮助未来的程序员

非常感谢@Alphonso...感谢您为帮助...所做的努力我做了以下操作，将从我的聊天机器人收到的图片作为电子邮件附件发送： 1-将我的电子邮件功能方法移动到 SummaryStepAsync 方法中。 2-使用 WebClient

下载用户接受的图像

 string contentURL = ticketProfile.screenShot.ContentUrl;
        string name = ticketProfile.screenShot.Name;
        using (var client = new WebClient())
        {
            client.DownloadFile(contentURL, name);
            client.DownloadData(contentURL);
            client.DownloadString(contentURL);
        }

3-将其传递到我的电子邮件功能

 try
        {
            HttpClient httpClient = new HttpClient();



            //Help Desk Email Settings
            MailMessage helpDeskMail = new MailMessage();
            if (ticketProfile.screenShot != null)
            {
                System.Net.Mail.Attachment data = new System.Net.Mail.Attachment(ticketProfile.screenShot.Name);
                helpDeskMail.Attachments.Add(data);
            }

就是这样:)
