向无状态服务交换矩阵应用添加应用洞察

const express = require('express');
const app = express();
const { ApplicationInsightsClient } = require('@azure/ai-application-insights');

// 初始化应用洞察客户端
const appInsightsClient = new ApplicationInsightsClient({
    endpoint: 'https://<your-endpoint>.cognitiveservices.azure.com/',
    apiKey: '<your-api-key>'
});

// 中间件：记录请求信息
app.use((req, res, next) => {
    const startTime = Date.now();
    res.on('finish', () => {
        const duration = Date.now() - startTime;
        appInsightsClient.trackRequest(req.method, req.url, res.statusCode, duration);
    });
    next();
});

// 示例路由
app.get('/', (req, res) => {
    res.send('Hello World!');
});

// 启动服务器
const PORT = process.env.PORT || 3000;
app.listen(PORT, () => {
    console.log(`Server is running on port ${PORT}`);
});
