Question

我在本地运行我的网站，测试“联系我们”页面功能。电子邮件永远不会在接收端通过，但没有任何预期。当用户提交表单时，这里是被调用的端点（我从http://www.mikesdotnetting.com/article/268/how-to-send-email-in-asp-net-mvc改编了大部分代码）：

[HttpPost]
public async Task<ActionResult> contact(ContactUsViewModel inputModel)
{
    try 
    {
        string body =
            "<h4>Email from <strong>{0}</strong> ({1})</h4>" +
            "<p>Date: {2}</p>" +
            "<p>Phone: {3}</p>" +
            "<p>Message:</p><p style='padding-left: 20px;'>{4}</p>" +
            "<br /><p style='font-size: 10px; color: gray;'>This email was generated by testsite.com</p>";
        string to = ConfigurationManager.AppSettings["ContactUsEmailAddress"];
        MailMessage message = new MailMessage();
        message.To.Add(new MailAddress(to));
        message.From = new MailAddress(inputModel.Email);
        message.Subject = "Message from " + inputModel.Name;
        message.Body = String.Format(body, new string[]
            {
                inputModel.Name, inputModel.Email, DateTime.Now.ToLongDateString(), inputModel.Phone, inputModel.UserMessage
            }
        );
        message.IsBodyHtml = true;

        using (var smtp = new SmtpClient())
        {
            var credential = new NetworkCredential
            {
                UserName = ConfigurationManager.AppSettings["EmailServerUserName"],
                Password = ConfigurationManager.AppSettings["EmailServerPassword"]
            };
            smtp.Credentials = credential;
            smtp.Host = ConfigurationManager.AppSettings["EmailServerHost"];
            smtp.Port = Convert.ToInt32(ConfigurationManager.AppSettings["EmailServerPort"]);
            smtp.EnableSsl = true;
            await smtp.SendMailAsync(message);
            return View(new ContactUsViewModel(true)); //return to the same page, but with form now emptied.
                                                       //"true" param tells the model/Razor page to show a "Email sent" message
        }
    }
    catch (Exception ex)
    {
        // handle exception
    }
}

这是我的web.config。我没有对默认的MVC模板web.config进行任何更改，只是在appSettings部分添加了5个新密钥，用于引用电子邮件信息。

这是我的第一个网站，也是我第一次实施电子邮件，所以非常感谢任何帮助。感谢。

编辑：可能不言而喻，但在我这边，我有真正的凭据写入web.config的ContactUsEmailAddress，EmailServerUserName和EmailServerPassword字段，而不是这里包含虚拟值。

Answer 1

参考@MRebati在他的回答中分享的文章，我能够通过从web.config中的手动appSettings键切换到正确的system.web > mailSettings > smtp设置来实现这一点。

  <system.net>
    <mailSettings>
      <smtp from="you@outlook.com">
        <network host="smtp-mail.outlook.com" 
                 port="587" 
                 userName="you@outlook.com"
                 password="password123" 
                 enableSsl="true" />
      </smtp>    
    </mailSettings>
  </system.net>

Answer 2

关闭SSL。

m <- leaflet() %>%
addTiles() %>%  # Add default OpenStreetMap map tiles
addMarkers(lng=174.768, lat=-36.852, popup="The birthplace of R")
m  # Print the map

当域使用HTTPS时，您必须只使用SSL。这不适用于localhost或仅http域。
