Nodemailer transporter -如何访问标准邮件字段？

Question

我正在编写一个简单的nodemailer传输器，但我在查找实际邮件消息数据结构的文档位置时遇到了麻烦。

我的send方法如下所示

send: function(mail, callback) {
  var data = {
    messageId: mail.message.getHeader('message-id'),
    from: mail.message.from,
    to: mail.message.to
  }
  console.log('data', data)
  // do stuff with data
  // etc
};

当我尝试使用如下消息进行此操作时：

var MYTestTransport = require('./');
var email = {
  headers: {
    'message-id': 'a very nice test'
  },
  from: "Bob <bob@test.tes>",
  to: "Alice <alice@test.tes>",
  subject: "Great Idea",
  text: 'This is a test.',
  html: '<p>This is a <strong>test</strong></p>'
};
var transport = nodemailer.createTransport(MYTestTransport());

transport.sendMail(email, function(err, data) {
  expect(err).to.not.exist;
  expect(data.messageId).to.equal('a very nice test');
  expect(data.from).to.equal('Bob <bob@test.tes>');
  expect(data.to).to.equal('Alice <alice@test.tes>')
  done()
});

然而，data最终成为

{
  messageId: 'a very nice test',
  to: undefined,
  from: undefined,
  subject: undefined
}

如何正确读取消息字段？这有记录在案吗？

根据git example，将from和to写为：

var email = {
   headers: {
  'message-id': 'a very nice test'
},
from: '"Bob" <bob@test.tes>',
to: '"Alice" <alice@test.tes>',
subject: "Great Idea",
text: 'This is a test.',
html: '<p>This is a <strong>test</strong></p>')
};
