我正在研究next.js项目，并且在本地运行我的项目时，我能够将电子邮件插入表单并通过其API成功地将其发布到MailChimp。在生产环境中，相同的代码不起作用，但我已经确认生产环境具有以下功能：

• 访问并更正MailChimp API密钥下一个API路由
• Api路线{URL}/subscribe返回200

问题似乎出在API路由被调用并且随后的API调用发生之后。我迷路了，很乐意您的见识。

pages / api / subscribe.js

const axios = require('axios');

const LIST_ID = 'b29d6f1e61'; // MailChimp Audience
const key = `Basic ${Buffer.from(`apikey:${process.env.MAILCHIMP_API_KEY}`).toString('base64')}`;


const subscribe = ( email ) => {
axios({
    method: 'POST',url: `https://us18.api.mailchimp.com/3.0/lists/${LIST_ID}/members/`,headers: {Authorization: key},data: { email_address: `${email}`,status: "subscribed" } })
    .then(response => {
        console.log(response);
        return response
    }).then(data => {
        console.log('Data Rec\'d:',data);
    }).catch(error => {
        console.log('Subscribe error:',error);
        // reject('Something went wrong')
    });

};

module.exports = async (req,res) => {
    if (req.method === 'POST') {
        res.setHeader('Content-Type','application/json');
        res.statusCode = 200;
        res.send(req);
        await subscribe(req.body);
        res.end()
    } else {
        res.setHeader('Content-Type','application/json');
        res.statusCode = 200;
        res.end(JSON.stringify({name: 'GET received'}))
    }
};
