1.我们准备了一个json文件(test.json)，在resource下面：

{
    "data": {
        "lastArea": {
            "areaId": 200,
            "label": 1,
            "name": "我是区服",
            "state": 1
        },
        "topArea": {
            "areaId": 10,
            "label": 0,
            "name": "我是区服",
            "state": 1
        },
        "total": 2
    },
    "rc": 0
}

	const char *des = NULL;
    std::string jsonpath;
    cs::CSJsonDictionary *jsonDict = NULL;
    jsonpath = CCFileUtils::sharedFileUtils()->fullPathForFilename("test.json");
    unsigned long size = 0;
    des = (char*)(CCFileUtils::sharedFileUtils()->getFileData(jsonpath.c_str(),"r" , &size));
	if(NULL == des || strcmp(des, "") == 0)
	{
		printf("read json file[%s] error!\n", "test.json");
	}
	CSJson::Reader cReader;
	CSJson::Value value;
   if(!cReader.parse(std::string(des), value, false))
   {CCLog("%s", cReader.getFormattedErrorMessages().data());}

	CCLog("areadId:%d, label:%d, name:%s, state:%d", value["data"]["lastArea"]["areaId"].asInt(),
		value["data"]["lastArea"]["label"].asInt(),
		value["data"]["lastArea"]["name"].asCString(),
		value["data"]["lastArea"]["state"].asInt());
