卡萨布兰卡问题检索json [英] Casablanca question retrieving json

问题描述

大家好，只是将我的脚趾浸入卡萨布兰卡世界并需要一些使用json :: value对象的帮助 - 我已经调用了一个服务器，该服务器返回JSON并在jsonValue中拥有我想要的数据，如下所示 - 我需要的元素是结果，我无法理解如何将它从集合中删除 - 我尝试了自动myres = jsonValue [3]，它给出了一个错误，没有运算符[]匹配这些操作数 - 任何想法？

Hi all, just dipping my toes into the Casablanca world and need some help working with json::value objects - I've made a call to a server which returns JSON and have the data I want in jsonValue as shown below - the element I need is "result" and I can't fathom out how to get it out of the collection - I've tried auto myres = jsonValue[3] which gives an error no operator "[]" matches these operands - any ideas ?

jsonValue dump
object {size = 4}
    [0]: (L"id", 1)
    [1]: (L"method", 0x0047c694 L"slim.request")
    [2]: (L"params", array {size = 2})
    [3]: (L"result", object {size = 11})
    [Raw View]: 0x0282f0c0 {m_value=unique_ptr {m_object={size = 4} } m_kind=Object(3) }
