C++ JsonCpp 从 arrayValue 更改 objectValue

Question

我想更改 slotList 的值。

slotList[1][1] = "1234";

我该如何解决这个问题？

这是我尝试过的:

JSON:

{

"slotList" : [

      [ "1452", "1452", "1452", "1452", "1452" ],
      [ "1452", "1452", "1452", "1452", "1452" ],
      [ "1452", "1452", "1452", "1452", "1452" ],
      [ "1452", "1452", "1452", "1452", "1452" ],
      [ "1452", "1452", "1452", "1452", "1452" ]
   ]
}

代码:

if (bIsParsed == true)
{
    Json::Value slotList = root["slotList"];

    Json::Value slot = slotList[currentIndex];
    Json::Value value = "111"; // what is wrong? do not change anything! OMG!
    slot[selectIndex].swap(value);
}

Json::StyledWriter writer;
string jsonData = writer.write(root);

Answer 1

Json::Value& slotList = root["slotList"];

Json::Value& slot = slotList[currentIndex];

插槽[selectIndex] = "1111";

std::cout << root.toStyledString() << std::endl;
