cocos2d-x 网络部分之Json数据包

 Json 采用Jsoncpp ， 从官网上下载源代码， 目录下面有2个目录：

1. jsoncpp/src/lib_json/ ，这里是json实现方法，要将以下文件加入到工程中

 

                   ../../Classes/jsoncpp/src/lib_json/json_reader.cpp \

                   ../../Classes/jsoncpp/src/lib_json/json_value.cpp \

                   ../../Classes/jsoncpp/src/lib_json/json_writer.cpp \

 

2. jsoncpp/include/json ，这里需要设置为include路径， 具体跨平台设置头文件路径，请参考：

（http://zgame.blog.51cto.com/6144241/1066817）

 

$(LOCAL_PATH)/../../Classes/jsoncpp/include/json \

//-------------------------------------------------------------------

Json使用方法: 

1. 解析

#include "json.h"
using namespace std;
Json::Reader reader;
Json::Value value;

void GameBoard::readJson(std::string net_response) {
//开始解析
if(reader.parse(net_response, value))
{
//读取string
Read_json_GameDataByString(value,"v");
Read_json_GameDataByString(value,"performance");
//解析数组
Json::Value arrayObj = value["result"];
for(unsigned int i = 0;i <arrayObj.size(); i++)
{
int errore = Read_json_GameDataByInt(arrayObj[i] ,"ecode");
....
}
}
}

2. 发送

void GameBoard::writeJson(std::string cmd, Json::Value params) {
    std::string ss;

    using namespace std;
    Json::FastWriter writer;
    Json::Value root;
    Json::Value arrayObj;
    Json::Value item;
    Json::Value dataArray;
    Json::Value dataItem;

    if (cmd == kNetGameInit)
    {

        _globalData.userInfo_.guid =  "test";

#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)

        if(!this->gameBoardDelegate->if_QQLogin()){
        char * ttt=  this->gameBoardDelegate->Get_Andorid_Udid();
        _globalData.userInfo_.guid =  * CCString::createWithFormat("%s",ttt);
        }
        else{
            // qq already set
        }
        CCLOG("_globalData.userInfo_.guid:%s",_globalData.userInfo_.guid.getCString());
#endif


        item["guid"] = 0;
        item["code"] = 00;
        params["sync"]=0;
    }
    else
    {
        item["guid"] = _globalData.userInfo_.udid.m_sString;
        item["code"] = _globalData.userInfo_.authcode;
        params["sync"]=1;
    }
    item["uid"] = _globalData.userInfo_.guid.m_sString;
    item["pid"] = "2";
    item["t"] = "";
    item["v"] = "1.3.4";
    item["key"] = "1234";
    item["server"]="1";

    dataItem["cmd"] = cmd;


    dataItem["params"] = params;
    dataArray.append(dataItem); //数组的处理方式
    item["data"] = dataArray;

    ss =  item.toStyledString();
    CCLOG("%s",ss.c_str());
    ss = writer.write(item);

    //json数据，http发送
    this->gameBoardDelegate->HttpDataSend(ss);


}

 

数据包加密在http网络收数据后和发数据前处理就可以。
