环回电子邮件连接器连接 ETIMEDOUT 错误

Question

我在email connector 看到了使用电子邮件连接器的环回文档 我在 datasources.js 中的电子邮件数据源如下：

"emailDataSource": {
"name": "emailDataSource",
"connector": "mail",
"transports":[{
  "type":"SMTP",
  "host": "stmp.gmail.com",
  "secure":true,
  "port":50,
  "auth":{
    "user":"test@gmail.com",
    "pass":"pass"
  }
}]}

还有我在 model-config.json 中的配置

"Email":{
"dataSource":"emailDataSource"}

这是我使用远程方法对模型 js 文件的测试：

MyModel.orderproduct = function(id, email, cb){
    MyModel.app.models.Email.send({
        to: email,
        from: 'test@gmail.com',
        subject: 'test subject',
        text : 'my text',
        html : 'my <em> html </em>'
    }, function(err, mail){
        console.log('email sent!' + mail);
        cb(err);
    });

}

MyModel.remoteMethod('orderproduct',{
    accepts:[{arg:'id',type : 'string', required: true},
            {arg: 'email', type : 'string', required : true}],
    http: {path : '/product/:id', verb : 'get',source: 'query'},
    return:{arg : 'res', type : 'Object'}
});

我的远程方法获得了请求成功的状态。但我从邮件连接器组件收到错误：

{"error": {
"statusCode": 500,
"name": "Error",
"message": "connect ETIMEDOUT 125.235.4.59:50",
"errno": "ETIMEDOUT",
"code": "ECONNECTION",
"syscall": "connect",
"address": "125.235.4.59",
"port": 50,
"command": "CONN",
"stack": "Error: connect ETIMEDOUT 125.235.4.59:50\n    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1189:14)"

} }

有人请提供一些使用 Loopback 框架的邮件连接器的高级或教程。 谢谢~

Answer 1

问题在于SMTP 服务器的配置。端口号应为465 而不是50。使用以下配置

"transports": [{
    "type": "SMTP",
    "host": "smtp.gmail.com",
    "secure": true,
    "port": 465,
    "auth": {
      "user": "name@gmail.com",
      "pass": "pass"
    }
  }]
