Node.js nodejs结束后写入-切换音频请求

我想知道如何使下面的脚本保持打开状态并继续编写

我需要它在广告结束时触发函数radio（）

错误

的默认行为是在读卡器结束时结束编写器

更改您的代码：

//请求（remoteUrl）.pipe（res）
请求（remoteUrl）.pipe（res，{end:false}）

var http = require('http'),
    request = require('request');
    var icecast = require('icecast-stack');
    let remote = 'http://stream.radiomedia.com.au:8000/stream';
    var stream = icecast.createReadStream(remote);
    var remoteUrl = remote;
    var ad = 0;



http.createServer(function (req, res) {

    res.writeHead(200, {
        'Content-Type': 'audio/mpeg'
    });




    stream.on('connect', function() {
        console.error("Radio Stream connected!");
      });

     stream.on('metadata', function(metadata) {
        var title = icecast.parseMetadata(metadata).StreamTitle;
        if(title === title){
        console.error("advert");
        ad = 1;
        if(ad === 1)
        {

            let remote='https://storage.googleapis.com/ad-system/DRN1_Indie.drn1.com.mp3';
            remoteUrl = remote+"?=Player" + req.url;

               request.get(remoteUrl)
                    .on('response', response => {
                        // pipe response to res 
                    console.error(title);
                    console.error(remoteUrl);
                     // since response is an http.IncomingMessage

                     /*setTimeout(function(){
                        ad = 0;
                         radio();
                     },20000);*/
                     response.pipe(res);

                })

                .on("finish", response => { 
                    return radio();
                });


        }

        }
        else{
            console.error(title);

        }
    });

function radio(){
                    let remote='http://stream.radiomedia.com.au:8003/stream';
                     remoteUrl = remote+"?=Player" + req.url;
                     request.get(remoteUrl)
                            .on('response', response => {
                                // pipe response to res 
                            //console.error(title);
                            //console.error(remoteUrl);
                            // since response is an http.IncomingMessage
                            response.pipe(res);
                        });
}

  // http://somewhere.com/noo.bin
  remoteUrl = remote+"?=Player" + req.url;
  //console.error(remoteUrl);
  //stream.pipe(process.stdout);/


  request(remoteUrl).pipe(res)
}).listen(8080);
