霸气三国2先说下这么项目的进度（进度有点慢每天晚上写一点努力坚持下去吧）已经完成了消息系统每个模块之间都是发送消息来完成数据通信的。

现在有主场景模块、信息公告模块、武将模块这三个模块都是在主场景模块上来撸的代码流程如下：

进入主场景之前会请求服务器发送scene.main请求

local pProxy = EMFacade:getInstance():retrieveProxy("SceneMainProxy")if(pProxy~=nil) then   pProxy:getSceneMain()endfunction SceneMainProxy:getSceneMain()    self:sendRequest("","&login=1",PTLNM.GET_SCENEMAIN)    -- bodyendvoid EMHttpClient::sendRequest(string url,string method){    HttpRequest* request = new HttpRequest();    CCLOG("%s",url.c_str());    request->setUrl(url.c_str());    request->setRequestType(HttpRequest::Type::GET);    // write the post data    request->setResponseCallback(CC_CALLBACK_2(EMHttpClient::onHttpRequestCompleted, this));    request->setTag(method.c_str());    HttpClient::getInstance()->setTimeoutForConnect(1500);    HttpClient::getInstance()->sendImmediate(request);    HttpClient::getInstance()->enableCookies(NULL);    request->release();}void EMHttpClient::onHttpRequestCompleted(HttpClient *sender, HttpResponse *response){    if (!response)    {        return;    }        // You can get original request type from: response->request->reqType    if (0 != strlen(response->getHttpRequest()->getTag()))    {        log("%s completed", response->getHttpRequest()->getTag());    }        long statusCode = response->getResponseCode();    char statusString[64] = {};    sprintf(statusString, "HTTP Status Code: %ld, tag = %s", statusCode, response->getHttpRequest()->getTag());    log("response code: %ld", statusCode);        if (!response->isSucceed())    {        log("response failed");        log("error buffer: %s", response->getErrorBuffer());        EMFacade::getInstance()->sendNotification("OTHER_UNLOCK",0);        return;    }        // dump data    std::vector *m_responseData =response->getResponseData();    long data_length =  m_responseData->size();    string json;        for (long i = 0;i<data_length;++i)     {         json+=m_responseData->at(i);    }    EMFacade::getInstance()->sendNotification(response->getHttpRequest()->getTag(),json);}

这样 c++中就是接受这些数据进行请求了

当客户端接受到服务器传回的数据后会发送一个response->getHttpRequest()->getTag() 的消息这个消息是从request->setTag(method.c_str());中获取的目的就是知道这个消息是什么类型的请求的是什么类型服务器发送回来的就是什么类型这是统一的

将得到的数据以json字符串的格式传到控制层。

      if notification then            notification = tolua.cast(notification, "EMNotification");            local jsonData = notification:getJsonData()            local cjson = require "cjson"            local data = cjson.decode(jsonData)            if data.rc ~= 0 then                cclog("数据出错")            else                --初始化主场景                local sceneMainProxy = EMFacade:getInstance():retrieveProxy("SceneMainProxy")                if nil ~= sceneMainProxy then                    sceneMainProxy.uid=data.user.uid;                    sceneMainProxy.name=data.user.name;                end                --初始化武将                local generalProxy = EMFacade:getInstance():retrieveProxy("GeneralProxy")                if nil ~=generalProxy then                    --武将信息                    generalProxy.generals_info=data.data.generals.generals_info                    --武将列表                    generalProxy.gid_list=data.data.generals.gid_list                    --武将布阵信息列表                    generalProxy.formations_info=data.data.generals.formations_info                end                EMFacade:getInstance():sendNotification(QMSG.LOAD_COMPLETE,0)            end        end

获取的数据才进行二次处理就是我们客户端要用到的数据了。其中客户端用到了 cjson
