不想使问题过于复杂,但我认为我需要发布与此错误相关的所有代码。
使用MvcMailer并引入了一个单独的Send
机制(用于 Orchard CMS 自己的电子邮件)。
MvcMailer 代码:
1) AskUsMailer.cs:
public class AskUsMailer : MailerBase, IAskUsMailer
{
public AskUsMailer()
: base()
{
//MasterName = "_Layout";
}
public virtual MvcMailMessage EMailAskUs(AskUsViewModel model)
{
var mailMessage = new MvcMailMessage { Subject = "Ask Us" };
ViewData.Model = model;
this.PopulateBody(mailMessage, viewName: "EMailAskUs");
return mailMessage;
}
}
2) IAskUsMailer.cs:
public interface IAskUsMailer : IDependency
{
MvcMailMessage EMailAskUs(AskUsViewModel model);
}
3) AskUsController.cs: (GETTING NULL REFERENCE ERROR BELOW)
[Themed]
public ActionResult Submitted()
{
//This is the new call (see new code below):
//Note: Debugging steps through eMailMessagingService,
//then shows the null reference error when continuing to
//SendAskUs
eMailMessagingService.SendAskUs(askUsData);
//Below is normal MvcMailer call:
//AskUsMailer.EMailAskUs(askUsData).Send();
return View(askUsData);
}
注意: askUsData 在控制器的单独块中定义:
private AskUsViewModel askUsData;
protected override void OnActionExecuting(ActionExecutingContext
filterContext)
{
var serialized = Request.Form["askUsData"];
if (serialized != null) //Form was posted containing serialized data
{
askUsData = (AskUsViewModel)new MvcSerializer().
Deserialize(serialized, SerializationMode.Signed);
TryUpdateModel(askUsData);
}
else
askUsData = (AskUsViewModel)TempData["askUsData"] ??
new AskUsViewModel();
TempData.Keep();
}
protected override void OnResultExecuted(ResultExecutedContext
filterContext)
{
if (filterContext.Result is RedirectToRouteResult)
TempData["askUsData"] = askUsData;
}
我不知道如何让我的 EMailMessagingService.cs(见下文)调用到控制器中,所以在控制器的一个单独块中我这样做了:
private IEMailMessagingService eMailMessagingService;
public AskUsController(IEMailMessagingService eMailMessagingService)
{
this.eMailMessagingService = eMailMessagingService;
}
我认为这是我问题的一部分。
现在,新代码试图连接到 Orchard 的电子邮件:
1)电子邮件消息服务.cs:
public class EMailMessagingService : IMessageManager
{
private IAskUsMailer askUsMailer;
private IOrchardServices orchardServices;
public EMailMessagingService(IAskUsMailer askUsMailer,
IOrchardServices orchardServices)
{
this.orchardServices = orchardServices;
this.askUsMailer = askUsMailer;
this.Logger = NullLogger.Instance;
}
public ILogger Logger { get; set; }
public void SendAskUs(AskUsViewModel model)
{
var messageAskUs = this.askUsMailer.EMailAskUs(model);
messageAskUs.To.Add("email@email.com");
//Don't need the following (setting up e-mails to send a copy anyway)
//messageAskUs.Bcc.Add(AdminEmail);
//messageAskUs.Subject = "blabla";
Send(messageAskUs);
}
....
}
EMailMessagingService.cs 还包含 Send 方法:
private void Send(MailMessage messageAskUs)
{
var smtpSettings = orchardServices.WorkContext.
CurrentSite.As<SmtpSettingsPart>();
// can't process emails if the Smtp settings have not yet been set
if (smtpSettings == null || !smtpSettings.IsValid())
{
Logger.Error("The SMTP Settings have not been set up.");
return;
}
using (var smtpClient = new SmtpClient(smtpSettings.Host,
smtpSettings.Port))
{
smtpClient.UseDefaultCredentials =
!smtpSettings.RequireCredentials;
if (!smtpClient.UseDefaultCredentials &&
!String.IsNullOrWhiteSpace(smtpSettings.UserName))
{
smtpClient.Credentials = new NetworkCredential
(smtpSettings.UserName, smtpSettings.Password);
}
if (messageAskUs.To.Count == 0)
{
Logger.Error("Recipient is missing an email address");
return;
}
smtpClient.EnableSsl = smtpSettings.EnableSsl;
smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
messageAskUs.From = new MailAddress(smtpSettings.Address);
messageAskUs.IsBodyHtml = messageAskUs.Body != null &&
messageAskUs.Body.Contains("<") &&
messageAskUs.Body.Contains(">");
try
{
smtpClient.Send(messageAskUs);
Logger.Debug("Message sent to {0} with subject: {1}",
messageAskUs.To[0].Address, messageAskUs.Subject);
}
catch (Exception e)
{
Logger.Error(e, "An unexpected error while sending
a message to {0} with subject: {1}",
messageAskUs.To[0].Address, messageAskUs.Subject);
}
}
}
现在,在 EMailMessagingService.cs 中,我收到了一个错误,表明事情没有被实现,所以我自动生成了以下内容(不知道这是否是我的错误的一部分):
public void Send(Orchard.ContentManagement.Records.ContentItemRecord recipient, string type, string service, System.Collections.Generic.Dictionary<string, string> properties = null)
{
throw new NotImplementedException();
}
public void Send(System.Collections.Generic.IEnumerable<Orchard.ContentManagement.Records.ContentItemRecord> recipients, string type, string service, System.Collections.Generic.Dictionary<string, string> properties = null)
{
throw new NotImplementedException();
}
public void Send(System.Collections.Generic.IEnumerable<string> recipientAddresses, string type, string service, System.Collections.Generic.Dictionary<string, string> properties = null)
{
throw new NotImplementedException();
}
public bool HasChannels()
{
throw new NotImplementedException();
}
public System.Collections.Generic.IEnumerable<string> GetAvailableChannelServices()
{
throw new NotImplementedException();
}
2) IEMailMessagingServices.cs
public interface IEMailMessagingService
{
MailMessage SendAskUs(AskUsViewModel model);
}
MvcMailer 可以在没有这个添加的情况下正常工作(在 Orchard 之外),但我正试图让一切在 Orchard 内工作。
我只是无法弄清楚我做错了什么。有什么想法吗?
抱歉代码过多。
