Node + react js在post请求中增加上传文件大小

npm install express body-parser

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

const app = express();

// 设置上传文件大小限制为10MB
app.use(bodyParser.json({ limit: '10mb' }));
app.use(bodyParser.urlencoded({ limit: '10mb', extended: true }));

// 处理post请求
app.post('/upload', (req, res) => {
  // 处理上传文件的逻辑
});

// 启动服务器
app.listen(3000, () => {
  console.log('Server is running on port 3000');
});
