cocoahttpserverを迅速に使用してオーディオ（デバイスソング）をストリーミングする方法は？

Question

1つのデバイスがサーバーとして動作し、他のデバイスが参加するアプリケーションを作成していますが、サーバーを作成できますが、オーディオをストリーミングする方法（デバイスローカルソング）が見つかりません。

ステップ：

1. 私はGCDWebServer

   でサーバーを作成

2. 取得NSDataのサーバに設定songData

MPMediaItem
からデフォルトのGetここで

を要求しますが、私のコードです：

class DjSocketServer : NSObject,GCDWebServerDelegate 
{ 
var myLocalServer = GCDWebServer() 
var isRunning = false 
var serverType = ServerType.isDj 


func startServer(with type:ServerType) 
{ 
    serverType = type 
    GCDWebServer.setLogLevel(4) 
    myLocalServer = GCDWebServer() 

    myLocalServer?.delegate = self 

    myLocalServer?.addDefaultHandler(forMethod: "GET", request: GCDWebServerRequest.self, processBlock: {request in 

     //Default Response to GET request 
     if let requestUrl = request?.url.absoluteString 
     { 
      if requestUrl.contains(".mp3") 
      { 
       return GCDWebServerDataResponse(data: playerInfo.songPlayedData as Data!, contentType: "audio/mp3") 
      } 
     } 

     let para:NSMutableDictionary = NSMutableDictionary() 
     para.setValue(DjInformation.party_name, forKey: "djName") 
     para.setValue(Common.DJ_Connected_Users.count, forKey: "listener") 
     para.setValue(DjInformation.dj_ip, forKey: "djIp") 
     para.setValue("http://\(DjInformation.dj_ip):\(AppConfig.Dj_Port)/atrist_poster", forKey: "djImg") 
     para.setValue(DjInformation.artist_name, forKey: "artist") 

     let jsonData = try! JSONSerialization.data(withJSONObject: para, options: JSONSerialization.WritingOptions.prettyPrinted) 
     return GCDWebServerDataResponse(data: jsonData, contentType: "application/json") 
    }) 

    //myLocalServer?.start(withPort: UInt(ServerPort.DjPort.rawValue), bonjourName: UIDevice.current.name) 
    do 
    { 
    try myLocalServer?.start(options: [GCDWebServerOption_AutomaticallySuspendInBackground:false,GCDWebServerOption_Port:UInt(ServerPort.DjPort.rawValue),GCDWebServerOption_BonjourName:UIDevice.current.name]) 
     print("\n\n\n\n\n\nSuccess Tag:Started ----- \n\n\n\n\n\n") 
    }catch 
    { 
     print("Error Tag : Starting MainDj Server") 
    } 
} 

func webServerDidStart(_ server: GCDWebServer!) { 
    print("Visit \(server.serverURL) in your web browser") 
    isRunning = true 
} 

func webServerDidCompleteBonjourRegistration(_ server: GCDWebServer!) { 
    print(" CompleteBonjourRegistration ") 
} 

func webServerDidStop(_ server: GCDWebServer!) { 
    print("\n\n\n\n\n\n\nServer Stoped MainDj\n\n\n\n\n\n\n") 
    isRunning = false 
} 
} 

私は、この関数にMPMediaItemを渡すと、ドキュメントディレクトリ内のmp3ファイルとしてNSDataの

class func getSongRawData(item: MPMediaItem,success: @escaping (NSData) -> Void,fail: @escaping (NSError) -> Void) -> Void { 

    if let exporter = createSongExporter(item: item) { 
     exporter.exportAsynchronously(completionHandler: {() -> Void in 
      switch exporter.status { 
      case .completed: 
       let rawData = NSData(contentsOf: exporter.outputURL!)! 
       songUrl_selected = (exporter.outputURL?.absoluteString)! 
       //print("UURL : ",exporter.outputURL?.absoluteString ?? "None") 
       success(rawData) 
      default: 
       let e = NSError(
        domain: "jp.co.faithcreates.Meowziq", 
        code: MusicManagerError.RawDataAccessFailed.rawValue, 
        userInfo: [ 
         "exporterStatus": exporter.status.rawValue 
        ]) 
       fail(e) 
      } 

      self.removeExportedFile(url: exporter.outputURL! as NSURL) 
     }) 
    } else { 
     let e = NSError(
      domain: "jp.co.faithcreates.Meowziq", 
      code: MusicManagerError.RawDataAccessFailed.rawValue, 
      userInfo: nil 
     ) 
     fail(e) 
    } 
} 

private class func createSongExporter(item: MPMediaItem) -> AVAssetExportSession? { 
    if let url = item.assetURL { 
     let asset = AVURLAsset(url: url, options: nil) 
     let exporter = AVAssetExportSession(asset: asset, presetName: AVAssetExportPresetAppleM4A) 

     exporter?.outputFileType = "com.apple.m4a-audio"; 

     let docDir = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0] 
     let fileName = createExportFileName() 
     exporter?.outputURL = NSURL(fileURLWithPath: docDir).appendingPathComponent(fileName) 

     return exporter 
    } else { 
     return nil 
    } 
} 

private class func createExportFileName() -> String { 
    let dateFormatter = DateFormatter() 
    dateFormatter.dateFormat = "yyyyMMddhhmmss" 
    let dateString = dateFormatter.string(from: NSDate() as Date) 
    return String(format: "%@.m4a", dateString) 
    //return String(format: "%@.m4a", "tmp") 
}

保存のNSDataに変換し、オーディオをストリーミングする」

以下

let fileResponse = GCDWebServerFileResponse(file: song_filePath) 
return fileResponse
