javascript – 通过nodemailer向多个收件人发送电子邮件

我正在尝试向多个收件人发送电子邮件.为此,我创建了一个收件人数组,但是使用我的代码,我只能将邮件发送到阵列的最后一次电子邮件ID三次.我的代码出了什么问题？

var nodemailer = require("nodemailer");

var smtpTransport = nodemailer.createTransport(
"SMTP",{
  host: '',
  //  secureConnection: true,         // use SSL
  port: 25
});

var maillist = [
  '****.sharma3@****.com',
  '****.bussa@****.com',
  '****.gawri@****.com',
];

var msg = {
    from: "******", // sender address
    subject: "Hello ✔", // Subject line
    text: "Hello This is an auto generated Email for testing  from node please ignore it  ✔", // plaintext body
    cc: "*******"    
    //  html: "<b>Hello world ✔</b>" // html body
}


maillist.forEach(function (to, i , array) {
  msg.to = to;

  smtpTransport.sendMail(msg, function (err) {
    if (err) { 
      console.log('Sending to ' + to + ' failed: ' + err);
      return;
    } else { 
      console.log('Sent to ' + to);
    }

    if (i === maillist.length - 1) { msg.transport.close(); }
  });
});

解决方法:

您的问题是从异步代码引用相同的msg对象.
forema在sendMail发送电子邮件之前完成.

所以msg.to将成为maiilist对象的最后一项.

尝试在maillist foreach中克隆/复制msg,或者只是将msg定义移动到那里：

maillist.forEach(function (to, i , array) {


  var msg = {
        from: "******", // sender address
        subject: "Hello ✔", // Subject line
        text: "Hello This is an auto generated Email for testing  from node please ignore it  ✔", // plaintext body
        cc: "*******"    
        //  html: "<b>Hello world ✔</b>" // html body
    }
  msg.to = to;

  smtpTransport.sendMail(msg, function (err) {
