nodemailer 不使用 api-gateway-url/dev/submit 发送

问：

我的 express.js nodemailer 有问题，因为当我使用 /submit 时，它适用于本地主机，但是当我使用 api 网关 url 时，它不适用于本地主机和上传的网站。顺便说一句，我使用 aws api 网关。

这是我的 express.js 中的我的应用程序.js

const express = require('express');
const bodyParser = require('body-parser');
const nodemailer = require('nodemailer');
const path = require('path');

const app = express();

// Middleware
app.use(bodyParser.urlencoded({ extended: true }));
app.use(express.static(__dirname)); // Serve static files

// Nodemailer transporter setup
let transporter = nodemailer.createTransport({
    service: 'gmail',
    auth: {
        type: 'OAuth2',
        user: 'my-email',
        clientId: 'number.apps.googleusercontent.com',
        clientSecret: 'number',
        refreshToken: 'number',
        accessToken: 'number',
        expires: 1484314697598
    }
});

app.get('my-api-url/dev/submit', (req, res) => {
    console.log('GET request received at /');
    res.sendFile(path.join(__dirname, 'contact.html'));
});

app.post('my-api-url/dev/submit', (req, res) => {
    console.log('POST request received at /submit');
    let formData = req.body;

    // Format the form data as columnar text
    let emailContent = Object.keys(formData).map(key => {
        return `${key}: ${formData[key]}`;
    }).join('\n');

    let mailOptions = {
        from: 'my-personal-email',
        to: 'my-other-personal-email',
        subject: 'Form Submission',
        text: emailContent
    };

    transporter.sendMail(mailOptions, (error, info) => {
        if (error) {
            console.error('Error sending email:', error);
            res.send('Failed to send email. Please try again later.');
        } else {
            console.log('Email sent:', info.response);
            res.redirect('contact.html?submitted=true');
        }
    });
});

app.use((req, res) => {
    console.log(`Route not found: ${req.url}`);
    res.status(404).sendFile(path.join(__dirname, '404.html'));
});

const PORT = 3000;
app.listen(PORT, () => {
    console.log(`Server is running on http://localhost:${PORT}`);
});

这是我的风格.js中的代码

document.addEventListener('DOMContentLoaded', function() {
    const form = document.querySelector('form');
    const submitButton = document.querySelector('input[type="submit"]');

    form.addEventListener('submit', async function(event) {
        event.preventDefault(); // Prevent the default form submission

        try {
            const formData = new FormData(form);
            const response = await fetch('my-api-url/dev/submit', {
                method: 'POST',
                body: formData
            });

            if (response.ok) {
                submitButton.value = 'Submitted';
                submitButton.disabled = true;
            } else {
                throw new Error('Error sending form data');
            }
        } catch (error) {
            console.error('Error:', error);
            alert('Error submitting form. Please try again.');
        }
    });
});

这是我的 AWS 函数的代码

const express = require('express')

// declare a new express app

  res.json({success: 'delete call succeed!', url: req.url});
});

app.listen(3000, function() {
    console.log("App started")
});

// Export the app object. When executing the application local this does nothing. However,
// to port it to AWS Lambda we will create a wrapper around that will load the app from
// this file
module.exports = app

我还没有尝试过任何代码。我希望代码将电子邮件发送到我的另一封电子邮件。它适用于带有 localhost 的 /submit，但当我使用 api-gateway-url/dev/submit 时它不起作用。而且它没有显示任何错误。
