如果您使用快递，请遵循此文档

在香草Node js中，您可以执行此操作

const http = require('http');
const url = require('url');

// Routes
const router = {
    /* '/myapp' route will be handled here and following function will be executed */
    'myapp': function (callback) {
        //we expect a callback function as argument
        callback(200, { name: 'sample handler' });
        //execute the callback function and pass 200 status code and a sample data which will send as response payload to user
    },
    'login': function(callback){
        callback(200, { name: 'Login' }); //You can add your routes in this object and handle them
    }
};

const server = http.createServer((req, res) => {
    // Get URL
    const parsedURL = url.parse(req.url, true);

    // Get Path
    const path = parsedURL.pathname; //This will give **http://127.0.0.1:8080/myapp **
    const trimmedPath = path.replace(/^\/+|\/+$/g, '');
    //This will get routes specified after base url in our case **myapp**

    req.on('data', (data) => {
        // streamed data. Browser will send data in stream, this func will run on each stream
    });

    // When Request in ended, all user requests can be handled in this event
    req.on('end', () => {
        // Handle Routes
        const choosenHandler = router[trimmedPath]; //Check in route obj

        //Send the callback function which was required
        choosenHandler(function (statusCode, payload) {
            // Send response to user
            const payloadString = JSON.stringify(payload);

            res.setHeader('Content-Type', 'text/html');
            res.writeHead(statusCode);
            res.write('<h1>Data: ' + payloadString + '</h1>'); //This will be sent to user
            console.log('returning response');
            res.end();
        });
    });
});

// Start the server
server.listen(3000, () => {
    console.log('Server Listening to 3000 port ');
});
