If you are usingbuild2, you can use thenlohmann-jsonpackage from the public repositoryhttps://cppget.orgor directly from thepackage's sources repository. In your project'smanifestfile, just adddepends: nlohmann-json(probably with someversion constraints). If you are not familiar with using depe...

是指将JSON数据映射到nlohmann json库中的结构数组对象。nlohmann json是一个开源的C++ JSON库,用于处理和操作JSON数据。 在nlohmann json库中,可以使用std::vector或std::array等容器类型来表示结构数组。结构数组是一个包含多个相同结构的元素的数组,每个元素都具有相同的属性和类型。 下面是一个示例代码,展示...
