统一消息系统

// 示例代码：基于Node.js的统一消息推送服务

const express = require('express');

const app = express();

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

app.use(bodyParser.json());

let filesDB = [];

// 接收投标文件

app.post('/upload', (req, res) => {

const file = req.body;

filesDB.push(file);

res.send({ message: 'File uploaded successfully.' });

});

// 更新文件状态并推送通知

app.put('/update/:id', (req, res) => {

const fileId = parseInt(req.params.id);

const updatedState = req.body.state;

filesDB[fileId].state = updatedState;

// 触发消息推送

notify相关人员(updatedState);

res.send({ message: 'File state updated.' });

});

function notify(state) {

// 假设使用WebSocket进行实时通知

io.emit('fileStatusUpdate', { state });

}

app.listen(3000, () => console.log('Server running on port 3000'));
