Json的嵌套创建

//例如下为Json格式
{"ErrorColor":"red","ErrorCode":123,"ResultValue":{"assyLot":"12345678901234567890","checkResult":"0","rankNo":"B"},"ErrorMessage":null,"ResultCode":0}
//在代码里创建一个Json格式的root
Json::Value root;
root["ErrorColor"] = "red";
root["ErrorCode"] = 123;
Json::Value ResultValue;
ResultValue["assyLot"] = "12345678901234567890";
ResultValue["checkResult"] = "0";
ResultValue["rankNo"] = "B";
root["ResultValue"] = ResultValue;
root["ResultCode"] = 0;
