通过用户指定的gmail帐户发送消息

Question

我正在制作一个电子邮件客户端。我希望用户输入他们的谷歌凭据，并能够发送消息到其他电子邮件。我会用nodemailer这样做，但谷歌似乎不允许nodemailer只使用用户名和密码发送消息。下面是我尝试做的一个例子:

const nodemailer = require('nodemailer');
async function main() {
let transporter = nodemailer.createTransport({
host: 'smtp.gmail.com',
port: 587,
secure: false,
auth: {
user: '[e-mail]',
pass: '******',
},
});
let info = await transporter.sendMail({
from: '"Divine" <[e-mail]>',
to: '[e-mail]',
subject: 'Hello',
text: 'Hello world?',
html: '<b>Hello world?</b>',
});
console.log('Message sent: %s', info.messageId);
}
main().catch(console.error);

我收到的错误是:

Node.js v18.12.1

}

是否有一种类型的谷歌认证，我可以使用，或者一些方法为用户配置nodemailer从他们的gmail发送电子邮件而不添加应用令牌?

我也试过允许不安全的应用程序访问我的Gmail作为解决方案，但这也不起作用。

首先去你的谷歌帐户，然后去步骤验证，然后点击和你的电子邮件密码第二步，进入安全选项，点击应用程序密码，然后选择你的设备和Windows，点击生成然后哪个代码生成复制和删除你的旧密码，写你的代码
