异步通信atmosphere.js

之前的项目，由于要照顾低端机型不支持websocket进行通信，选择了atmosphere.js，
在不支持websocket的环境下，使用long-polling长轮询方式进行，很好用。特做个笔记。

$(function () {   var request = {        url: ajaxServerUrl + '/chat/doctor/' + data.relationId,        contentType: "application/json",        logLevel: 'debug',        transport: 'websocket',        trackMessageLength: true,        reconnectInterval: 5000,        fallbackTransport: 'long-polling'    };   request.onOpen = function(response) {        uuid = response.request.uuid;        $.atmosphere.subscribe(request).push(atmosphere.util.stringifyJSON({            clientId: localStorage.id,            type: '2',            uuid: uuid        }));        console.log("聊天开始了："+localStorage.id);  };    request.onMessage = function (response) {//监听         console.log(response.responseBody);         var msgObj = atmosphere.util.parseJSON(response.responseBody);   };   request.onClose = function(response) {    //          subSocket.push(atmosphere.util.stringifyJSON({author: author, message: 'disconnecting'}));};request.onError = function(response) {    logged = false;};request.onReconnect = function(request, response) {    // content.html($('', {text: 'Connection lost, trying to reconnect. Trying to reconnect ' + request.reconnectInterval}));    // input.attr('disabled', 'disabled');};   $.atmosphere.subscribe(request);//发送}
