node net创建的tcp连接实例如何关闭

Question

var server = net.createServer(function(connection) { 
   console.log('client connected');

   connection.on('end', function() {
      console.log('客户端关闭连接');
   });

   connection.write('Hello World!\r\n');
    
   connection.pipe(connection);

});

server.listen(8080, function() { 
  console.log('server is listening');
});

现在想手动关闭connection，要用什么方法呀，找了好久....

Answer 1

connection.destroy()可以关掉

Answer 2

server.cloes([callback])，关闭不了么？
