Getting A Specific Item With JsonCpp

[EverydayDiesel]

Hello,

Can anyone please tell me how I can access the value of menu.item1.element1-1 (which would be "value1-1" with the jsoncpp library. For some reason I dont seem to be able to get that value.


// here is the json

"menu":{
      "item1":{
     "element1-1":"value1-1",
     "element1-2":"value1-2",
     "element1-3":"value1-3"
      },
      "item2":{
     "element2-1":"value2-1",
     "element2-2":"value2-2",
     "element2-3":"value2-3"
      },
   }
}

//here is the cpp code

Json::Value root;
Json::Reader reader;
constJson::Value defValue;
std::ifstream ifile("inputjson.txt");


bool isJsonOK =( ifile != NULL && reader.parse(ifile, root));
if(isJsonOK)
{
    Json::Value val = root.get("menu","");
    for(Json::Value::iterator it = val.begin(); it != val.end();++it)
    {
         Json::Value key = it.key();
         Json::Value value =(*it);


         // how do i get the details of 'menuValue'
         const Json::Value menuValue = root["menu"]["item1"];


   }
}

Your json is missing the first brace (before "menu"), but I assume you know that.
Is this what you want:

    Json::Value v = root["menu"]["item1"]["element1-1"];
    std::cout << v.asString() << std::endl;
