我使用以下自定义模块作为NodeMailer的包装器
var nodemailer = require("nodemailer");
function Emailer(to, subject, message) {
this.to = to;
this.subject = subject;
this.message = message;
this.smtpTransport = nodemailer.createTransport("SMTP",{
service: "Gmail", // sets automatically host, port and connection security settings
auth: {
user: "*******",
pass: "*******"
}
});
this.send = send;
function send() {
this.smtpTransport.sendMail({ //email options
from: "******* <*****>", // sender address. Must be the same as authenticated user if using Gmail.
to: this.to, // receiver
subject: this.subject, // subject
text: this.message // body
}, function(error, response){ //callback
if(error){
//console.log(error);
}else{
//console.log("Message sent: " + response.message);
}
smtpTransport.close(); // shut down the connection pool, no more messages. Comment this line out to continue sending emails.
});
};
}
module.exports = Emailer;
我这样实现:
var emailer = require('./models/emailer.js');
var myEmailer = new emailer('--------', 'my subject', 'my message');
myEmailer.send();
它有效,但我仍然收到此错误:
ReferenceError: smtpTransport is not defined
at MailComposer.returnCallback (/Users/drewwyatt/Sites/JS/Node/Tutorials/email/models/emailer.js:28:7)
我做错了什么?

问题在于这一行:
smtpTransport.close();
您可以通过将回调绑定到邮件的上下文来避免ReferenceError
。
this.smtpTransport.sendMail({ /* options */ }, function (err, response) {
// do stuff
this.smtpTransport.close();
}.bind(this));
将send
作为方法放在原型上也更有意义,因为它使用了实例的状态。
Emailer.prototype.send = function () {
// this.smtpTransport ...
};
最后,我将其命名为Email
而不是Emailer
:)

...
var self = this;
function send() {
this.smtpTransport.sendMail({ //email options
from: "******* <*****>", // sender address. Must be the same as authenticated user if using Gmail.
to: this.to, // receiver
subject: this.subject, // subject
text: this.message // body
}, function(error, response){ //callback
if(error){
//console.log(error);
}else{
//console.log("Message sent: " + response.message);
}
self.smtpTransport.close(); // shut down the connection pool, no more messages. Comment this line out to continue sending emails.
});
