首先，确保您已经安装了multer和express：
npm install multer express
然后，您可以使用以下代码来设置一个Express服务器，该服务器能够接收Blob格式的文件上传：
在项目一级目录，创建uploads文件夹和server.js
const express = require('express');
const multer = require('multer');
const app = express();
// 配置存储选项
const storage = multer.diskStorage({
destination: function (req, file, cb) {
cb(null, 'uploads/'); // 保存的路径，确保这个目录存在
},
filename: function (req, file, cb) {
cb(null, file.originalname); // 使用原始文件名作为保存的文件名
}
});
// 创建multer实例
const upload = multer({ storage: storage });
// 设置允许跨域请求，如果需要的话
app.use((req, res, next) => {
res.header('Access-Control-Allow-Origin', '*');
res.header('Access-Control-Allow-Methods', 'GET, POST');
next();
});
// 定义上传路由
app.post('/upload', upload.single('file'), (req, res) => {
// req.file 包含了上传文件的信息
if (!req.file) {
return res.status(400).send('No file uploaded');
}
// 文件上传成功
res.send(`File uploaded successfully. ${req.file.filename}`);
});
// 启动服务器
const port = 3000;
app.listen(port, () => {
console.log(`Server running on port ${port}`);
});启动服务
