Question

我已连接x个客户端。

如果我的API出现问题，这意味着如果我收到3个部分的数据，我该如何将其推送给特定的客户？

var socketio = require('socket.io');
exports.socketServer = function (app, server) {
  var clients = [];
  var io = socketio.listen(server);
  io.sockets.on('connection', function (socket) {

  });
});

示例API /回调（这是另一个文件）

exports.callback = function(req, res){
    //how do reach my socket.io and my clients from here
};

你可以传递io。这是一种方式，在API /回调文件

中

var io;

var initializeSocket = function (socket) {
    io = socket;
}

var callback = function (req, res) {
    // your code here and which will have a reference to io object
}

module.exports = {callback: callback, initializeSocket: initializeSocket};

在此之前你必须从这里用io对象调用那个Api /回调模块的initializeSocket方法，

var socketio = require('socket.io');
var Api = require(./location_to_your_Api_callback_file);

exports.socketServer = function (app, server) {
  var clients = [];
  var io = socketio.listen(server);
  Api.initilizeSocket(io);
  io.sockets.on('connection', function (socket) {

  });
});

如何从API路由到达socket.io客户端
