问题 I want to use jsoncpp for writing a C++ code in order to parse a JSON file. Let me explain what I did. I created a CMakeLists.txt and I made a FindJsoncpp.cmake along with a simple c++ file to test jsoncpp . When I compile the C++ source without cmake using -I/usr/include/jsoncpp/ -ljsoncpp it works fine. but when I try to build it using cmake it cannot find json.h header file that I included in my c++ source code. here is my CMakeLists.txt : cmake_minimum_required (VERSION 2.6) project

I understand that json::value can

JsonCpp - when having a json::Value object, how can i know it's key name?

由 我们两清 提交于 2019-12-06 01:39:07
问题 Let suppose I have this Json file: [ { "id": 0 } ] using jsoncpp, i can have a Json::Value object by doing this: Json::Value node = root[0u]["id"]; OK, somewhere else in the code, I'm getting that node object, and I want to get some info out of it. I can get its value, like this: int node_value = node.asInt(); But how can I get its NAME? (i.e the "id"). It should be something like: string node_name = node.Name(); //or maybe: string node_name2 = node.Key(); but I can't find anything similar.
