Koa使用koa-body上传文件问题

1. 确认koa-body中间件是否正确使用： const Koa = require('koa'); const koaBody = require('koa-body'); const app = new Koa();

app.use(koaBody({ multipart: true, formidable: { maxFileSize: 20010241024, } }));

2. 确认表单中是否正确设置了enctype属性： <form method="POST" action="/upload" enctype="multipart/form-data"> <input type="file" name="file"> <button type="submit">上传</button> </form>

3. 确认服务器端接收文件的方式是否正确： const Koa = require('koa'); const koaBody = require('koa-body'); const app = new Koa();

app.use(koaBody({ multipart: true, formidable: { maxFileSize: 20010241024, } }));

app.use(async (ctx) => { const file = ctx.request.files.file; // 处理上传的文件 });

4. 确认处理文件的函数是否正确实现： const fs = require('fs'); const path = require('path');

function uploadFile(file) { const readStream = fs.createReadStream(file.path); const writeStream = fs.createWriteStream(path.resolve(__dirname, './dist', file.name)); readStream.pipe(writeStream); }

app.use(async (ctx) => { const file = ctx.request.files.file; uploadFile(file); ctx.response.body = '上传成功'; });
