pomelo新建一个服务类型

需求：一个购买物品demo

客户端发起请求事例：客户端—->前端（connector）——->后端（game）

服务端

pomelo前端connector：新建connector.entryHandler.js

module.exports = function(app) {
  return new Handler(app);
};

var Handler = function(app) {
  this.app = app;
};

/**
 * New client entry.
 *
 * @param  {Object}   msg     request message
 * @param  {Object}   session current session object
 * @param  {Function} next    next step callback
 * @return {Void}
 */
Handler.prototype.entry = function(msg, session, next) {
//  next(null, {code: 200, msg: 'game server is ok.'});

var uid= msg.name;

session.bind(uid);
session.pushAll();

session.on("closed" , function(){
	console.log("玩家"+ session.uid + "断开了链接");
})

next(null,"链接成功");

};

entry 负责维护客户端的session 包括建立绑定等，玩家进入后返回一个成功字段，并且分配session，uid为客户端名字。

pomelo后端game：负责具体的购买逻辑，该服务不可直接和客户端通讯，也就是客户端pomelo.init 不能连接到后端服务器game，新建文件game/handler/gameHandler.js

module.exports = function(app) {
	return new Handler(app);
};

var Handler = function(app) {
	this.app = app;
};
var handler=Handler.prototype;

handler. getNotify = function(msg, session, next) {
//console.log(msg)
//console.log(session)


	next(null, {msg:"欢迎玩家" + msg.name + "进入游戏"});
	
};



handler.buyGoods=function(msg,session,next){
	var id=msg.id;
	var count = msg.count;
	console.log("购买物品玩家 uid:" + session.uid);

	if(id == "100" &&  count ==1){
		next(null,{msg:"购买物品:#活血丹 成功",code:200}); // 返回客户端
	}else{
				next(null,{msg:"你的金币不足，购买失败",code:200}); // 返回客户端调用
	}

}
//客户端通过pomelo.request("game.gameHandler.buyGoods",{id:"100",count:1},function(data){
//来发起此请求
            		

配置：

servers.json // 配置
