【问题描述】：

我正在尝试将 Sendgrid api 合并到我的 nodejs 项目中，但它不起作用。

我的代码：

const sgMail = require('@sendgrid/mail');
sgMail.setApiKey('SG.5sNiSHdLTLqFK-jzAiM2WA.gd6wBmu5FzqXVQPe8Ey1yFjKjX1MXnu6sMafSeys');
const msg = {
  to: 'vishal@gmail.com',
  from: 'kartik@gmail.com',
  subject: 'Sending with Twilio SendGrid is Fun',
  text: 'and easy to do anywhere, even with Node.js',
  html: '<strong>and easy to do anywhere, even with Node.js</strong>',
};
sgMail.send(msg);
console.log('check   ')

我收到以下错误：

尽可能为您的 Mongo 连接添加更多详细信息

【解决方案1】：

错误与 Mongo/Mongoose 连接有关，与 Sendgrid API 无关。

请验证以下几行：

(node:12732) UnhandledPromiseRejectionWarning: MongooseServerSelectionError: connect ECONNREFUSED 127.0.0.1:27017
    at NativeConnection.Connection.openUri (C:\Users\Niranjan\Desktop\krb\web d\node\login-system\node_modules\mongoose\lib\connection.js:826:32)
    at Mongoose.connect (C:\Users\Niranjan\Desktop\krb\web d\node\login-system\node_modules\mongoose\lib\index.js:335:15)
    at Object.<anonymous> (C:\Users\Niranjan\Desktop\krb\web d\node\login-system\src\db\mongoose.js:3:10)

请检查您的 Mongo 连接。
