在 Dart 中发送 SMTP 邮箱

有一个名为mailer的图书馆，它的功能正是你想要的:发送邮箱.

将其设置为pubspec.yaml中的依赖项，然后运行pub install:

dependencies:
  mailer: any

我将给出一个在本地Windows计算机上使用Gmail的简单示例:

import 'package:mailer/mailer.dart';

main() {
  var options = new GmailSmtpOptions()
    ..username = 'kaisellgren@gmail.com'
    ..password = 'my gmail password'; // If you use Google app-specific passwords, use one of those.

  // As pointed by Justin in the comments, be careful what you store in the source code.
  // Be extra careful what you check into a public repository.
  // I'm merely giving the simplest example here.

  // Right now only SMTP transport method is supported.
  var transport = new SmtpTransport(options);

  // Create the envelope to send.
  var envelope = new Envelope()
    ..from = 'support@yourcompany.com'
    ..fromName = 'Your company'
    ..recipients = ['someone@somewhere.com', 'another@example.com']
    ..subject = 'Your subject'
    ..text = 'Here goes your body message';

  // Finally, send it!
  transport.send(envelope)
    .then((_) => print('email sent!'))
    .catchError((e) => print('Error: $e'));
}

GmailSmtpOptions只是一个帮手类.如果要使用本地SMTP服务器:

var options = new SmtpOptions()
  ..hostName = 'localhost'
  ..port = 25;

你可以在SmtpOptions班考check here for all possible fields分.

下面是一个使用流行的Rackspace Mailgun的例子:

var options = new SmtpOptions()
  ..hostName = 'smtp.mailgun.org'
  ..port = 465
  ..username = 'postmaster@yourdomain.com'
  ..password = 'from mailgun';

该库还支持HTML邮箱和附件.查看the example了解如何做到这一点.

我个人使用mailer与邮枪在生产中使用.
