使用 nodemailer 通过 Node.js 发送电子邮件不起作用

Question

提问by Sprout Coder

I've set up a basic NodeJS server (using the nodemailer module) locally (http://localhost:8080) just so that I can test whether the server can actually send out emails.

我已经在本地 ( http://localhost:8080)设置了一个基本的 NodeJS 服务器（使用 nodemailer 模块），以便我可以测试服务器是否真的可以发送电子邮件。

If I understand the SMTP option correctly (please correct me if I'm wrong), I can either try to send out an email from my server to someone's email account directly, orI can send the email, still using Node.js, but via an actual email account(in this case my personal Gmail account), i.e using SMTP. This option requires me to login into that acount remotely via NodeJS.

如果我理解正确的SMTP选项（请纠正我，如果我错了），我可以尝试从我的服务器发送电子邮件给某人的电子邮件帐户直接，或者我可以发送电子邮件，仍然使用Node.js的，但通过实际的电子邮件帐户（在这种情况下是我的个人 Gmail 帐户），即使用 SMTP。此选项要求我通过 NodeJS 远程登录该帐户。

So in the server below I'm actually trying to use NodeJs to send an email from my personal email account to my personal email account.

所以在下面的服务器中，我实际上是在尝试使用 NodeJs 从我的个人电子邮件帐户向我的个人电子邮件帐户发送电子邮件。

Here's my simple server :

这是我的简单服务器：

var nodemailer = require('nodemailer');
var transporter = nodemailer.createTransport("SMTP", {
    service: 'Gmail',
    auth: {
        user: '*my personal Gmail address*',
        pass: '*my personal Gmail password*'
    }
});

var http = require('http');
var httpServer = http.createServer(function (request, response)
{
    transporter.sendMail({
       from: '*my personal Gmail address*',
       to: '*my personal Gmail address*',
       subject: 'hello world!',
       text: 'hello world!'
    });
}).listen(8080);

However, it's not working. I got an email by Google saying :

但是，它不起作用。我收到了一封来自 Google 的电子邮件，内容是：

Google Account: sign-in attempt blocked If this was you You can switch to an app made by Google such as Gmail to access your account (recommended) or change your settings at https://www.google.com/settings/security/lesssecureappsso that your account is no longer protected by modern security standards.

Google 帐户：登录尝试被阻止如果是您您可以切换到 Google 制作的应用程序（例如 Gmail）来访问您的帐户（推荐）或在https://www.google.com/settings/security/更改您的设置lesssecureapps使您的帐户不再受现代安全标准的保护。

I couldn't find a solution for the above problem on the nodemailer GitHub page. Does anyone have a solution/suggestion ?

我在 nodemailer GitHub 页面上找不到上述问题的解决方案。有没有人有解决方案/建议？

Thanks! :-)

谢谢！:-)

The answer is in the message from google.

答案在来自谷歌的消息中。

Go to : https://www.google.com/settings/security/lesssecureapps
set the Access for less secure appssetting to Enable

转到：https: //www.google.com/settings/security/lesssecureapps
将安全性较低的应用程序的访问设置设置为启用

For the second part of the problem, and in response to

对于问题的第二部分，以及响应

I'm actually simply following the steps from the nodemailer github page so there are no errors in my code

我实际上只是按照 nodemailer github 页面中的步骤操作，因此我的代码中没有错误

I will refer you to the nodemailer github page, and this piece of code :

我将向您推荐 nodemailer github 页面，以及这段代码：

var transporter = nodemailer.createTransport({
service: 'Gmail',
auth: {
    user: '[email protected]',
    pass: 'userpass'
}
});

It differs slightly from your code, in the fact that you have : nodemailer.createTransport("SMTP". Remove the SMTP parameter and it works (just tested). Also, why encapsulating it in a http server? the following works :

它与您的代码略有不同，因为您有 : nodemailer.createTransport("SMTP"。删除 SMTP 参数，它可以工作（刚刚测试过）。另外，为什么要将其封装在 http 服务器中？以下作品：

var nodemailer = require('nodemailer');
var transporter = nodemailer.createTransport({
    service: 'Gmail',
    auth: {
        user: 'xxx',
        pass: 'xxx'
    }
});

console.log('created');
transporter.sendMail({
from: '[email protected]',
  to: '[email protected]',
  subject: 'hello world!',
  text: 'hello world!'
});

For those who actually want to use OAuth2 / don't want to make the app "less secure", you can achieve this by

对于那些真正想要使用 OAuth2 / 不想让应用程序“不那么安全”的人，您可以通过

Search "Gmail API" from the google API consoleand click "Enable"
Follow the steps at https://developers.google.com/gmail/api/quickstart/nodejs. In the quickstart.js file, changing the SCOPESvar from ['https://www.googleapis.com/auth/gmail.readonly']to ['https://mail.google.com/']in the quickstart js file provided as suggested in troubleshooting at https://nodemailer.com/smtp/oauth2/
After following the steps in (2), the generated JSON file will contain the acessToken, refreshToken, and expiresattributes needed in the OAuth2 Examples for Nodemailer

从谷歌 API 控制台搜索“Gmail API”并点击“启用”
按照https://developers.google.com/gmail/api/quickstart/nodejs 中的步骤操作。在quickstart.js文件，改变了SCOPES从VAR['https://www.googleapis.com/auth/gmail.readonly']到['https://mail.google.com/']所提供的快速入门js文件作为提示故障排除https://nodemailer.com/smtp/oauth2/
下面（2）中的步骤之后，将所生成的JSON文件将包含acessToken，refreshToken和expires属性需要在用于Nodemailer的OAuth2实例

This way you can use OAuth2 authentication like the following

这样您就可以使用 OAuth2 身份验证，如下所示

let transporter = nodemailer.createTransport({
    service: 'Gmail',
    auth: {
        type: 'OAuth2',
        user: '[email protected]',
        clientId: '000000000000-xxx0.apps.googleusercontent.com',
        clientSecret: 'XxxxxXXxX0xxxxxxxx0XXxX0',
        refreshToken: '1/XXxXxsss-xxxXXXXXxXxx0XXXxxXXx0x00xxx',
        accessToken: 'ya29.Xx_XX0xxxxx-xX0X0XxXXxXxXXXxX0x',
        expires: 1484314697598
    }
});

instead of storing your gmail password in plaintext and downgrading the security on your account.

而不是以明文形式存储您的 Gmail 密码并降低您帐户的安全性。

While the above answers do work, I'd like to point out that you can decrease security from Gmail by the following TWOsteps.

虽然上述答案确实有效，但我想指出您可以通过以下两个步骤来降低 Gmail 的安全性。

STEP #1

第1步

Google Account: sign-in attempt blocked If this was you You can switch to an app made by Google such as Gmail to access your account (recommended) or change your settings at https://www.google.com/settings/security/lesssecureappsso that your account is no longer protected by modern security standards.

Google 帐户：登录尝试被阻止如果是您您可以切换到 Google 制作的应用程序（例如 Gmail）来访问您的帐户（推荐）或在https://www.google.com/settings/security/更改您的设置lesssecureapps使您的帐户不再受现代安全标准的保护。

STEP #2

第2步

In addition to enabling Allow less secure apps, you might also need to navigate to https://accounts.google.com/DisplayUnlockCaptchaand click continue.

除了启用允许不太安全的应用程序外，您可能还需要导航到https://accounts.google.com/DisplayUnlockCaptcha并单击继续。

For debugging purpose it is handy to implement a callback function (they never do on the nodemailer github page) which shows the error message (if there is one).

出于调试目的，实现一个显示错误消息（如果有的话）的回调函数（他们从来没有在 nodemailer github 页面上做）是很方便的。

transporter.sendMail({
    from: from,
    to: to,
    subject: subject,
    html: text
}, function(err){
    if(err)
        console.log(err);
})

It helped me solve my problem... Turns out newer versions are not working properly:

它帮助我解决了我的问题......结果是新版本无法正常工作：

"Looks like nodemailer 1.0 has breaking changes so 0.7 must be used instead: http://www.nodemailer.com/

“看起来 nodemailer 1.0 有重大变化，所以必须使用 0.7：http://www.nodemailer.com/

Message posted on nodemailer as of 12/17/15:

截至 2015 年 12 月 17 日在 nodemailer 上发布的消息：

Do not upgrade Nodemailer from 0.7 or lower to 1.0 as there are breaking changes. You can continue to use the 0.7 branch as long as you like. See the documentation for 0.7 here."

不要将 Nodemailer 从 0.7 或更低版本升级到 1.0，因为存在重大更改。只要你愿意，你可以继续使用 0.7 分支。请参阅此处0.7 的文档。”

You only need App password for google auth, then replace your google password in your code. go here https://myaccount.google.com/apppasswords

您只需要 google auth 的 App 密码，然后在您的代码中替换您的 google 密码。去这里https://myaccount.google.com/apppasswords

sample code:

示例代码：

const nodemailer = require('nodemailer');
var transporter = nodemailer.createTransport({
    service: "Gmail",
    auth: {
      user: '[email protected]',
      pass: 'app password here'
    }
  });
transporter.sendMail(option, function(error, info){
    if (error) {
      console.log(error);
    } else {
      console.log('Email sent: ' + info.response);
    }
});

And install smtp module as dependency:

并安装 smtp 模块作为依赖项：

npm install smtp

var nodemailer = require('nodemailer');

var transporter = nodemailer.createTransport({
  service: 'gmail',
  type: "SMTP",
  host: "smtp.gmail.com",
  secure: true,
  auth: {
    user: '[email protected]',
    pass: 'YourGmailPassword'
  }
});

var mailOptions = {
  from: '[email protected]',
  to: '[email protected]',
  subject: 'Sending Email to test Node.js nodemailer',
  text: 'That was easy to test!'
};

transporter.sendMail(mailOptions, function(error, info){
  if (error) {
    console.log(error);
  } else {
    console.log('Email sent');
  }
});

Go to https://myaccount.google.com/lesssecureappsand change it ONbecause Some apps and devices use less secure sign-in technology, which makes your account more vulnerable. You can turn off access for these apps, which we recommend, or turn on access if you want to use them despite the risks.

转到https://myaccount.google.com/lesssecureapps并将其更改为ON，因为某些应用和设备使用安全性较低的登录技术，这会使您的帐户更容易受到攻击。您可以关闭这些应用程序的访问权限（我们建议您这样做），或者如果您想使用它们而不顾风险打开访问权限。
