今天和组员一起做弹窗，发现将弹窗抽离出的factory真心不错

这两天一直在做ionic开发，期间有个诉求是要完成ionic与socket.io对接，中间绕了不少弯子，故留下笔记。

先叙述下基本的诉求：

  • Nodejs 做为服务端，主要做服务端消息的监听与发送
  • 客户端App 为服务端发送消息
  • 主要协议TCP

服务端代码如下：

var http= require('http'), io= require('socket.io');
var app = http.createServer(), io = io.listen(app);
app.listen(10010);
io.sockets.on('connection', function (socket) {
  socket.emit('news', { hello: 'world' });//监听，一旦客户端连接上，即发送数据，第一个参数'new'为数据名，第二个参数既为数据
  socket.on('my new event', function (data) {//捕获客户端发送名为'my other event'的数据
    console.log(data.my);
  });
  socket.emit('other', { hello: 'other world' });//发送另一个数据
  socket.on('event1', function (data) {//捕获另外一个数据
    console.log(data);
  });
});

Ionic 部分：

  • 生成新项目：ionic start chat-app blank
  • 引入angular-socket-io 库:bower install angular-socket-io
  • folder
  • 注入socket.io在项目里：var app=angular.module('ionic-socketio-chat-client', ['ionic','btford.socket-io'])

  • 在index.html导入socket.io，注：socket.io/socket.io.js是服务端动态生成

     <script src="http://192.168.0.101:10010/socket.io/socket.io.js"></script>
<script src="lib/angular-socket-io/socket.js"></script>

    10
    11
    var socket = io.connect('http://192.168.0.101:10010');
          // io.set('origins', '*:*');
          socket.on('news', function(data) {
              console.log(data.hello);
          });
          socket.on('other', function(data) { //接收另一个名为'other'数据，  
              console.log(data.hello);
              socket.emit('event1', {
                  my: 'other data'
              });
          });

如此，客户端调用成功。

上次发博文记得是五月，中间mac更新了一次，ruby1.9.3 用不了，缺少组件，于是rebuild and reintall ruby, 折腾了一个钟左右，之后rake 生成文章，deploy 尽然上传不上去，又一个钟pass了。在种种不能忍受的情况下，果断切到hexo.真的是很很力呀！！！
