来自 Node.js 服务器应用程序的 SendGrid CORS 错误

如何解决来自 Node.js 服务器应用程序的 SendGrid CORS 错误

我只是想从 SendGrid 文档中获取一个简单的示例。这部分代码是从我的 Node.js + Express 应用程序中调用的：

function sendConfirmationEmail() {
    const sgMail = require('@sendgrid/mail');
    sgMail.setApiKey(process.env.SENDGRID_API_KEY);
    const msg = {
        to: '[e-mail]',// Change to your recipient
        from: '[e-mail]',// Change to your verified sender
        subject: 'Hello,world!',text: 'Thank you for your interest. We will let you kNow if we need any more information.',html: '<strong>Thank you for your interest. We will let you kNow if we need any more information.</strong>',};
    sgMail
        .send(msg)
        .then(() => {
            console.log('Email sent')
        })
        .catch((error) => {
            console.error(error)
        });
}

看到这个记录：

> { Error: Forbidden
    at axios.then.catch.error (node_modules/@sendgrid/client/src/classes/client.js:146:29)
    at process._tickCallback (internal/process/next_tick.js:68:7)
  code: 403,message: 'Forbidden',response:
   { headers:
      { server: 'Nginx',date: 'Sat,27 Feb 2021 15:58:48 GMT','content-type': 'application/json','content-length': '281',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] } } }

不确定为什么这是 CORS 错误，因为它不会发生在浏览器中。有什么想法吗？

来自 SendGrid 的建议解决方法没有帮助：

您可以创建一个基于服务器的应用程序，以保护您的 API 密钥不被公开。可以实现 NodeJS、PHP、Ruby、Python、C#、Go 和 Java 等语言，以从锁定的服务器环境的安全性调用 API。
