Sendgrid Web API 基本安装不使用 Meteor 方法发送电子邮件

Question

我正在为 Node.js 使用 SendGrid WebAPI。

我遵循了这些说明：

我从客户端触发的方法中有以下代码。

// using SendGrid's v3 Node.js Library
// https://github.com/sendgrid/sendgrid-nodejs
const sgMail = require('@sendgrid/mail');
sgMail.setApiKey(process.env.SENDGRID_API_KEY);
const msg = {
  to: 'test@example.com',
  from: 'test@example.com',
  subject: 'Sending with 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);

当我触发发送方法时，我收到一个奇怪的错误（如下）- 不确定为什么会这样。希望有一些想法。

谢谢！！

错误：

首先，将您的 API_KEY 放在客户端，就是在展示它，它应该保密。

创建一个新文件server/smtp.js。通过将它放在 server/ 目录中，Meteor 将只把它放在服务器端，这段代码在客户端是不可见的：

Meteor.startup(function () {
  process.env.MAIL_URL = 'smtp://username:password@smtp.sendgrid.net:587';
});

将电子邮件包添加到流星。在命令行上：

meteor add email

创建文件server/methods.js以添加一些服务器端方法：

Meteor.methods({
  sendmail(to) {
    // for security reasons, you should validate the 'to' argument
    // but let's forget that for now.
    Email.send({
      from: "me@paulpedrazzi.com",
      to: to
      subject: "Awesome",
      text: "It worked"
    });
  }
});

每当您想发送电子邮件时，在客户端调用此方法并向其传递必要的参数：

Meteor.call('sendmail', ‘elon.musk@tesla.com’, (err, res) => {
  if (err) {
    alert(err);
  } else {
    // success!
  }
});

希望对您有所帮助。
