node-eos

eos(https://github.com/ulyn/eos) client for node.js

This module has been tested to work with eos version 2.1.0.

Installation

You can install it using npm:

$ npm install node-eos

How to use

（1） init eos :

	var eos = require("node-eos");
	eos.init({
	    zookeeper_ip: '127.0.0.1',
	    zookeeper_port: 2181,
	    long_connect: true,
	    exclude_eos:[],//ignore eos
	    debugging_server_ip: '', //联调服务端ip,多个应用可以用分号隔开，没有冒号的为默认，有具体指定则使用具体的。如：127.0.0.1；app1：192.168.0.60；app2:192.168.0.65
	    use_mock: false, //全局控制是否使用mock
	    mock_online:true,//mock数据是否使用在线，当user_mock为true时生效
	    filter:[] //path为正则表达式 {"path":/appid/testService/*,filter:new Filter()}
	});

（2） definde a eos service，you can use eos-uddi to generate it

	
	module.exports = function(eos,mockConfig){
	    function testType(){
	        eos.Service.call(this);
	        this.appId = "test";
	        this.serviceId = "testType";
	        this.serviceVersion = "1.3";
	    }
	    eos.util.inherits(testType,eos.Service);
	
	    testType.prototype.testMap = function(map,str,successFunc,errorFunc){
	        var req = this._createReqPro("testMap",map,str);
	        eos.call(req,successFunc,errorFunc,mockConfig);
	    }
	    testType.prototype.testMap.paramKey = ["map","str"];
	
	    return testType;
	}

（3） call service

	
	var testType =  require("./testType")(eos);

    new testType().testMap({"a":"1","b":"2"},"abc",function(data){
        console.log("get result："+JSON.stringify(data));
    },function(e){
        console.log("exception："+e);
    });
