如何让我的Next.JS应用编程接口电子邮件路由将主机IP地址发送到SendGrid？

import sgMail from '@sendgrid/mail';
import os from 'os';

export default async (req, res) => {
  const hostIP = os.networkInterfaces().eth0[0].address; // 获取主机IP地址
  // 使用SendGrid发送电子邮件，将主机IP地址作为邮件内容发送
  sgMail.setApiKey(process.env.SENDGRID_API_KEY);
  const msg = {
    to: 'recipient@example.com',
    from: 'sender@example.com',
    subject: 'Host IP Address',
    text: `The host IP address is: ${hostIP}`,
  };
  try {
    await sgMail.send(msg);
    res.status(200).json({ message: 'Email sent successfully' });
  } catch (error) {
    res.status(500).json({ error: 'Failed to send email' });
  }
};

import React, { useEffect, useState } from 'react';

const MyComponent = () => {
  const [emailSent, setEmailSent] = useState(false);

  useEffect(() => {
    const sendEmail = async () => {
      try {
        const response = await fetch('/api/sendgrid');
        const data = await response.json();
        if (response.ok) {
          setEmailSent(true);
        } else {
          console.error(data.error);
        }
      } catch (error) {
        console.error('Failed to send email:', error);
      }
    };

    sendEmail();
  }, []);

  return (
    <div>
      {emailSent ? (
        <p>Email sent successfully!</p>
      ) : (
        <p>Sending email...</p>
      )}
    </div>
  );
};

export default MyComponent;
