html文件

    <form method="post" enctype="multipart/form-data" action="/api/upload">
        <input type="text" name="username">
        <input type="password" name="password">
        <input type="file" name="file">
        <input type="submit">
    </form>

upload.js文件 const fs = require('fs') const path = require('path') const FormData = require('form-data') const express = require('express') const fetch = require('node-fetch') const router = express.Router() const multipart = require('connect-multiparty'); var multipartMiddleware = multipart() router.post('/upload', multipartMiddleware, function (req, res) { // console.log(req.body, req.files); const { path: filePath, originalFilename } = req.files.file const newPath = path.join(path.dirname(filePath), originalFilename) fs.rename(filePath, newPath, function (err) { if (err) { return; } else { const file = fs.createReadStream(newPath) const form = new FormData() form.append('file', file) fetch('http://localhost:8080/upload', { method: "POST", body: form }) } }) res.json({}) }); module.exports = router;
