MessageBox

基于golang 和 reids pubsub 实现的sever sent events 服务器，可以用来对接任意平台作为消息推送

Usage

There is one route to listen to message published:

GET /messagebox

port default: 9977

1. need to set four environments

REDISADDR=127.0.0.1:6379 // 配置的redis server 地址
REDISDB=0 // 配置的redis DB

2. html 5 client example

        var sse = new EventSource("http://localhost:9977/messagebox");
        sse.onmessage = function(event) {
            console.log(event.data);
            document.getElementById("result").innerHTML+=event.data + "<br>";
        }
        sse.onerror = function(event) {
        console.log(event);

How to dockerize this service

1. 为了得到小的image，我们build outside dockerfile

注意编译的系统应选择cross-linux 64，以适应alpine docker image base

go build -o MessageBox

2. build docker

docker build -t lzhao/messagebox

3. start up service

利用docker-compose启动服务

docker-compose up -f docker-compose.yml -d --force-recreate --remove-orphans
