问题描述
我正在使用Rotativa将我的视图转换为pdf.我想将生成的pdf作为电子邮件附件发送(而不必先将其下载到磁盘上).我一直在遵循一堆教程来做到这一点,但是我一直在转圈.我将不胜感激.
I am using Rotativa to convert my view to pdf. I would like to send that generated pdf as an email attachment (without having to download it first to disk). I've been following a bunch of tutorials to do this but I just keep going round in circles. I would much appreciate any help I can get.
public async Task<IActionResult>SomeReport()
{
...
return new ViewAsPdf (report)
}
return view();
MemoryStream memoryStream = new MemoryStream();
MimeMessage msg = new MimeMessage();
MailboxAddress from = new MailboxAddress ("Name", "emailAddress")
msg.From.Add(from);
MailboxAddress to = new MailboxAddress ("Name", "emailAddress")
msg.From.Add(to);
BodyBuilder bd = new BodyBuilder();
bb.HtmlBody ="some text";
bb.Attachments.Add("attachmentName", new MemoryStream());
msg.Body = bb.ToMessageBody();
SmtpClient smtp = new SmtpClient();
smtp.Connect("smtp.gmail.com",465, true);
smtp.Authenticate("emailAddress", "Pwd");
smtp.Send(msg);
smtp.Disconnect(true);
smtp.Dispose();
编辑
Parent View from which Email is sent
@Model MyProject.Models.EntityViewModel
<a asp-action= "SendPdfMail" asp-controller ="Student" asp-route-id = "@Model.Student.StudentId">Email</a>
...
SendPdfMail action in Student Controller
public async Task<IActionResult> SendPdfMail(string id)
{
var student = await context.Student. Where(s => s.StudentId == id);
if (student != null)
{
...
var viewAsPdf = new ViewAsPdf("MyPdfView", new{route = id})
{
Model = new EntityViewModel(),
FileName = PdfFileName,
...
}
}
};

Nuget
Install-package Rotativa.AspNetCore
样品控制器
public class SendPdfController : ControllerBase
{
private const string PdfFileName = "test.pdf";
private readonly SmtpClient _smtpClient;
public SendPdfController(SmtpClient smtpClient)
{
_smtpClient = smtpClient;
}
[HttpGet("SendPdfMail")] // https://localhost:5001/SendPdfMail
public async Task<IActionResult> SendPdfMail()
{
using var mailMessage = new MailMessage();
mailMessage.To.Add(new MailAddress("a@b.c"));
mailMessage.From = new MailAddress("c@d.e");
mailMessage.Subject = "mail subject here";
var viewAsPdf = new ViewAsPdf("view name", <YOUR MODEL HERE>)
{
FileName = PdfFileName,
PageSize = Size.A4,
PageMargins = { Left = 1, Right = 1 }
};
var pdfBytes = await viewAsPdf.BuildFile(ControllerContext);
using var attachment = new Attachment(new MemoryStream(pdfBytes), PdfFileName);
mailMessage.Attachments.Add(attachment);
_smtpClient.Send(mailMessage); // _smtpClient will be disposed by container
return new OkResult();
}
}
选项类
public class SmtpOptions
{
public string Host { get; set; }
public int Port { get; set; }
public string Username { get; set; }
public string Password { get; set; }
}
在Startup#ConfigureServices
In Startup#ConfigureServices
services.Configure<SmtpOptions>(Configuration.GetSection("Smtp"));
// SmtpClient is not thread-safe, hence transient
services.AddTransient(provider =>
{
var smtpOptions = provider.GetService<IOptions<SmtpOptions>>().Value;
return new SmtpClient(smtpOptions.Host, smtpOptions.Port)
{
// Credentials and EnableSsl here when required
};
});
appsettings.json
appsettings.json
{
"Smtp": {
"Host": "SMTP HOST HERE",
"Port": PORT NUMBER HERE,
"Username": "USERNAME HERE",
"Password": "PASSWORD HERE"
}
}
