为什么Microsoft bot框架不可扩展？

Question

在群集之后,它无法按预期工作,并一次又一次地询问我的名字.

我错过了什么吗？

这是我的微软机器人框架代码.

server.js

var worker = require('./worker');
var cluster = require('cluster');


var spawnWorker = function() {
  worker.createServer();
};

var createCluster = function() {
  if(cluster.isMaster) {
    var cpus = require('os').cpus().length;
    for(var i = 0; i < cpus; i++) {
      cluster.fork();
    }
    cluster.on('online', function(wkr) {
      console.log('Worker started', wkr.process.pid);
    });
    cluster.on('exit', function(wkr) {
      console.log('Worker died, respawing', wkr.process.pid);
      cluster.fork();
    });
  } else {
    spawnWorker();
  }
};

createCluster();

worker.js

exports.createServer = function(){
    var builder = require('botbuilder');
    var connector = new builder.ConsoleConnector().listen();
    var bot = new builder.UniversalBot(connector);
    bot.dialog('/', [
        function (session) {
            builder.Prompts.text(session, process.pid+': Hi! What is your name?');
        },
        function (session, results) {
            session.send(process.pid+':Hello %s!', results.response);
        }
    ]);
}

产量

$ node server.js 

Worker started 8540
Worker started 8068
Worker started 6020
Worker started 4244

8540: Hi! What is your name?
abc
8068: Hi! What is your name?
prq
6020: Hi! What is your name?
lmn
4244: Hi! What is your name?
xyz

您在Worker.js文件中使用ConsoleConnector,该文件将所有机器人对话跟踪状态存储在内存中.这意味着每个节点都有一个单独的会话状态副本,这在多节点体系结构中不起作用.您需要使用使用BotFramework的ChatConnector将对话状态存储在机器人的一个中心位置,否则您必须将自定义IBotStorage实现传递给UniversalBot.该实现可以使用redis缓存或其他东西来集中所有内容.
