问题描述

我想知道是否有人可以帮忙处理一个 MVC 联系表，在提交时发送电子邮件?我想我已经设置了大多数元素，但由于某种原因，表单似乎正在发送(需要很长时间)然后返回表单并没有收到电子邮件.

MailModels.cs:

命名空间 WebApplication1.Models{公共类邮件模型{公共字符串名称 { 获取；放;}公共字符串电子邮件{获取；放;}公共字符串电话{得到;放;}公共字符串消息 { 获取；放;}}}

Contact.cshtml:

@using (Html.BeginForm("Contact", "Home", new { ReturnUrl = ViewBag.ReturnUrl }, FormMethod.Post, new { @id = "contact-form", role = "form"})){@Html.ValidationSummary()<字段集><div class="form-div-1"><label class="name">@Html.TextBoxFor(m => m.Name, new { @placeholder = "Name *", @type = "text" })

<div class="form-div-2"><label class="email">@Html.TextBoxFor(m => m.Email, new { @placeholder = "Email Address *", @type = "email" })

<div class="form-div-3"><label class="phone notRequired">@Html.TextBoxFor(m => m.Telephone, new { @placeholder = "电话号码", @type = "text" })

<div><label class="message">@Html.TextAreaFor(m => m.Message, new { @placeholder = "Message *" })

<div class="button-wrapper"><input type="submit" value="Send" name="submit" class="button"><input type="reset" value="Reset" name="MFReset" class="button"><span>*必填字段</span>

</fieldset>}

HomeController.cs:

使用系统；使用 System.Collections.Generic;使用 System.Data;使用 System.Data.Entity;使用 System.Linq；使用 System.Net.Mail；使用 System.Web；使用 System.Web.Mvc;使用 System.Web.Mvc.Html;使用 WebApplication1.Models;使用 System.Text;命名空间 WebApplication1.Controllers{公共类 HomeController : 控制器{公共 ActionResult 联系(){ViewBag.Message = "测试表格";返回视图()；}[HttpPost]公共 ActionResult 联系人(MailModels e){如果(模型状态.IsValid){StringBuilder message = new StringBuilder();MailAddress from = new MailAddress(e.Email.ToString());message.Append("姓名:" + e.Name + "
");message.Append("Email: " + e.Email + "
");message.Append("电话:" + e.Telephone + "

");message.Append(e.Message);MailMessage 邮件 = new MailMessage();SmtpClient smtp = 新 SmtpClient();smtp.Host = "smtp.mail.yahoo.com";smtp.Port = 465;System.Net.NetworkCredential 凭据 = new System.Net.NetworkCredential("yahooaccount", "yahoopassword");smtp.Credentials = 凭证；smtp.EnableSsl = true;mail.From = from;mail.To.Add("雅虎邮箱地址");mail.Subject = "测试查询来自"+e.Name;mail.Body = message.ToString();smtp.Send(mail);}返回视图()；}

用这个把我的头撞在砖墙上，任何帮助将不胜感激:-)

解决方案

发送电子邮件需要时间.它应该是一个线程.将您的代码放在一个函数中.并进行以下更改:

public void SendEmail(string toAddress, string fromAddress,字符串主题，字符串消息){尝试{使用 (var mail = new MailMessage()){const string email = "username@yahoo.com";const string password = "密码！";var loginInfo = new NetworkCredential(email, password);mail.From = new MailAddress(fromAddress);mail.To.Add(new MailAddress(toAddress));mail.Subject = 主题；mail.Body = 消息；mail.IsBodyHtml = true;尝试{使用 (var smtpClient = new SmtpClient("smtp.mail.yahoo.com", 465)){smtpClient.EnableSsl = true;smtpClient.UseDefaultCredentials = false;smtpClient.Credentials = loginInfo;smtpClient.Send(mail);}}最后{//处理客户端邮件处理()；}}}catch (SmtpFailedRecipientsException ex){foreach(ex.InnerExceptions 中的 SmtpFailedRecipientException t){var status = t.StatusCode;if (status == SmtpStatusCode.MailboxBusy ||状态 == SmtpStatusCode.MailboxUnavailable){Response.Write("传递失败 - 5 秒后重试.");System.Threading.Thread.Sleep(5000);//重发//smtpClient.Send(message);}别的{Response.Write("无法将消息发送到 {0}",t.FailedRecipient);}}}catch (SmtpException Se){//在这里处理异常Response.Write(Se.ToString());}捕获(异常前){Response.Write(ex.ToString());}}

在控制器中调用该函数:

[HttpPost]公共 ActionResult 联系人(MailModels e){如果(模型状态.IsValid){//准备邮件var toAddress = "someadress@yahoo.co.uk";var fromAddress = e.Email.ToString();var subject = "测试查询来自"+ e.Name;var message = new StringBuilder();message.Append("姓名:" + e.Name + "
");message.Append("Email: " + e.Email + "
");message.Append("电话:" + e.Telephone + "

");message.Append(e.Message);//启动邮件线程var tEmail = new Thread(() =>SendEmail(toAddress, fromAddress, subject, message));tEmail.Start();}返回视图()；}

如果您没有收到电子邮件，请检查您的垃圾邮件文件夹

I wonder if someone can please help with a MVC Contact Form which send an Email on submission? I think I have most elements setup, but for some reason the form appear to be sending (takes ages) then just returns back to the form and no email is received.

MailModels.cs:

namespace WebApplication1.Models
{
    public class MailModels
    {
       public string Name { get; set; }
       public string Email { get; set; }
       public string Telephone { get; set; }
       public string Message { get; set; }
    }
}

Contact.cshtml:

@using (Html.BeginForm("Contact", "Home", new { ReturnUrl = ViewBag.ReturnUrl }, FormMethod.Post, new { @id = "contact-form", role = "form" }))
{
    @Html.ValidationSummary()
    <fieldset>
        <div class="form-div-1">
            <label class="name">
                @Html.TextBoxFor(m => m.Name, new { @placeholder = "Name *", @type = "text" })
            </label>
        </div>
        <div class="form-div-2">
            <label class="email">
                @Html.TextBoxFor(m => m.Email, new { @placeholder = "Email Address *", @type = "email" })
            </label>
        </div>
        <div class="form-div-3">
            <label class="phone notRequired">
                @Html.TextBoxFor(m => m.Telephone, new { @placeholder = "Telephone Number", @type = "text" })
            </label>
        </div>
        <div>
            <label class="message">
                @Html.TextAreaFor(m => m.Message, new { @placeholder = "Message *" })
            </label>
        </div>
        <div class="button-wrapper">
            <input type="submit" value="Send" name="submit" class="button"> <input type="reset" value="Reset" name="MFReset" class="button"><span>* Required Fields</span>
        </div>
    </fieldset>
}

HomeController.cs:

using System;
using System.Collections.Generic;
using System.Data;
using System.Data.Entity;
using System.Linq;
using System.Net.Mail;
using System.Web;
using System.Web.Mvc;
using System.Web.Mvc.Html;
using WebApplication1.Models;
using System.Text;

namespace WebApplication1.Controllers
{
    public class HomeController : Controller
    {
    public ActionResult Contact()
    {
        ViewBag.Message = "Test Form";

        return View();
    }

    [HttpPost]
    public ActionResult Contact(MailModels e)
    {
        if (ModelState.IsValid)
        {

            StringBuilder message = new StringBuilder();
            MailAddress from = new MailAddress(e.Email.ToString());
            message.Append("Name: " + e.Name + "
");
            message.Append("Email: " + e.Email + "
");
            message.Append("Telephone: " + e.Telephone + "

");
            message.Append(e.Message);

            MailMessage mail = new MailMessage();

            SmtpClient smtp = new SmtpClient();

            smtp.Host = "smtp.mail.yahoo.com";
            smtp.Port = 465;

            System.Net.NetworkCredential credentials = new System.Net.NetworkCredential("yahooaccount", "yahoopassword");

            smtp.Credentials = credentials;
            smtp.EnableSsl = true;

            mail.From = from;
            mail.To.Add("yahooemailaddress");
            mail.Subject = "Test enquiry from "+e.Name;
            mail.Body = message.ToString();

            smtp.Send(mail);
        }
        return View();
    }

Banging my head against a brickwall with this one, any help would be much appreciated :-)

解决方案

Sending an email will take time. It should be a thread. Put your code in a function. And make the following changes:

public void SendEmail(string toAddress, string fromAddress, 
                      string subject, string message)
{
    try
    {
        using (var mail = new MailMessage())
        {
            const string email = "username@yahoo.com";
            const string password = "password!";

            var loginInfo = new NetworkCredential(email, password);


            mail.From = new MailAddress(fromAddress);
            mail.To.Add(new MailAddress(toAddress));
            mail.Subject = subject;
            mail.Body = message;
            mail.IsBodyHtml = true;

            try
            {
                using (var smtpClient = new SmtpClient(
                                                 "smtp.mail.yahoo.com", 465))
                {
                    smtpClient.EnableSsl = true;
                    smtpClient.UseDefaultCredentials = false;
                    smtpClient.Credentials = loginInfo;
                    smtpClient.Send(mail);
                }

            }

            finally
            {
                //dispose the client
                mail.Dispose();
            }

        }
    }
    catch (SmtpFailedRecipientsException ex)
    {
        foreach (SmtpFailedRecipientException t in ex.InnerExceptions)
        {
            var status = t.StatusCode;
            if (status == SmtpStatusCode.MailboxBusy ||
                status == SmtpStatusCode.MailboxUnavailable)
            {
                Response.Write("Delivery failed - retrying in 5 seconds.");
                System.Threading.Thread.Sleep(5000);
                //resend
                //smtpClient.Send(message);
            }
            else
            {
                Response.Write("Failed to deliver message to {0}",
                                  t.FailedRecipient);
            }
        }
    }
    catch (SmtpException Se)
    {
        // handle exception here
        Response.Write(Se.ToString());
    }

    catch (Exception ex)
    {
        Response.Write(ex.ToString());
    }

}

Call that function in your controller:

[HttpPost]
public ActionResult Contact(MailModels e)
{
    if (ModelState.IsValid)
    {

        //prepare email
        var toAddress = "someadress@yahoo.co.uk";
        var fromAddress = e.Email.ToString();
        var subject = "Test enquiry from "+ e.Name;
        var message = new StringBuilder();
        message.Append("Name: " + e.Name + "
");
        message.Append("Email: " + e.Email + "
");
        message.Append("Telephone: " + e.Telephone + "

");
        message.Append(e.Message);

        //start email Thread
        var tEmail = new Thread(() => 
       SendEmail(toAddress, fromAddress, subject, message));
        tEmail.Start();
    }
    return View();
}

If you dont get email, check your spam folder
