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,"total": 2
},"rc": 0
}
2.我们在onEnter函数中加入如下代码
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());}这样，我们的value对象中就存储到了json里面的数据。我们则可以取里面的数据。取法如下
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());
