Here I am facing one issue with Callbacks in socket.io with nodejs

{'success':'1','data':message},function(deliverycb){

推荐答案

首先，从id中获取套接字对象，您可以参考Socket.IO 1.0.x：按ID获取套接字

First, get socket object from id, which you can refer to Socket.IO 1.0.x: Get socket by id

然后用套接字对象 socket.emit（'type'，'message'，ack => {}）;
