问题描述

我正在关注 Node.js 上的 Sendgrid 设置指南(https://app.sendgrid.com/guide/integrate/langs/nodejs),但我不断收到 API 密钥错误。

这是我的代码:

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 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)
  .then(() => console.log('send mail success'))
  .catch(console.log);

我的 .env 文件中正确设置了我的 API 密钥:

SENDGRID_API_KEY=SG.oqKbQHcNxxxxxxxxxxxxxkY5B4o

这是我收到的错误消息:

API key does not start with "SG.".
ResponseError: Unauthorized
    at BE-KeyCon/node_modules/@sendgrid/client/src/classes/client.js:133:29
    at processTicksAndRejections (internal/process/task_queues.js:97:5) {
  code: 401,
  response: {
    headers: {
      server: 'nginx',
      date: 'Fri, 12 Jun 2020 21:31:08 GMT',
      'content-type': 'application/json',
      'content-length': '116',
      connection: 'close',
      'access-control-allow-origin': 'https://sendgrid.api-docs.io',
      'access-control-allow-methods': 'POST',
      'access-control-allow-headers': 'Authorization, Content-Type, On-behalf-of, x-sg-elas-acl',
      'access-control-max-age': '600',
      'x-no-cors-reason': 'https://sendgrid.com/docs/Classroom/Basics/API/cors.html'
    },
    body: { errors: [Array] }
  }
}

如果我将 API 密钥设置为字符串,如下所示:

sgMail.setApiKey('SG.oqKbQHcNxxxxxxxxxxxxxkY5B4o')

然后它工作。但显然出于安全原因,我不能这样离开。知道为什么它会以这种方式运行以及如何解决它吗?

解决方案


从 npm安装dotenv包并使用这段代码来确保它需要 .env 文件:

if (process.env.NODE_ENV !== 'production') require('dotenv').config();

控制台记录process.env.SENDGRID_API_KEY以检查程序是否正在获取 api 密钥。
