我如何在vercel上使用带有nextjs的强大功能上传文件

问题描述

api/upload.js

import formidable from 'formidable';

export const config = {
  api: {
    bodyParser: false,},};

export default async (req,res) => {
  const form = new formidable.IncomingForm();
  form.uploadDir = "./";
  form.keepExtensions = true;
  form.parse(req,(err,fields,files) => {
    console.log(err,files);
    res.send(err || "DONE")
  });
};

api/get.js

export default async (_,res) => {
    const fs = require('fs');
    fs.readdir("./",files) => {
        console.log(err)
        res.send(err || files)
    });
};

在 localhost 一切正常，但当我将其部署到 vercel 时却无法正常工作。

解决方法

您需要一个具有文件系统访问权限的服务器
