Nodemailer 与 Gmail 出现环回错误 - 对象 #<Object> 没有方法“getToken”

Question

我正在学习 Loopback，我决定发送一些电子邮件。我想使用 Gmail 帐户。 我创建了远程方法并配置了数据源。这是它的样子：

"myEmailDataSource": {
"name": "myEmailDataSource",
"connector": "mail",
"transports": [
  {
    "type": "smtp",
    "host": "smtp.gmail.com",
    "auth": {
      "xoauth2": {
        "user": "[email protected]",
        "clientId": "myClientId.apps.googleusercontent.com",
        "clientSecret": "mySecret",
        "refreshToken": "myToken"
      }
    }
  }
]

}

但是当我想发送电子邮件时，它会抛出此错误：

TypeError: Object #<Object> has no method 'getToken'
at SMTPConnection._handleXOauth2Token (/home/arth95/Projects/firstCMS/node_modules/loopback/node_modules/nodemailer/node_modules/nodemailer-smtp-transport/node_modules/smtp-connection/src/smtp-connection.js:961:67)

这是为什么？

Answer 1

作为解决方法，我已经完成了以下操作。

1. 在服务器oot中创建启动脚本
2. 在脚本中编写以下代码

var email = app.models.Email;

var auth = email.dataSource.connector.transports[0].transporter.options.auth;

auth.xoauth2 = require('xoauth2').createXOAuth2Generator(auth.xoauth2);

这会将您在数据源中定义的 xoauth2 对象转换为 Nodemailer 所需的 XOAuth2Generator 对象。

您需要安装xoauth2模块。
