如何使用nlhoman json在c++中将相同的键json数据合并为一个

#include <nlohmann/json.hpp>

nlohmann::json mergedJson;

std::vector<nlohmann::json> jsonVector;

nlohmann::json json1 = R"(
    {
        "key": "value1",
        "data": "data1"
    }
)"_json;

nlohmann::json json2 = R"(
    {
        "key": "value2",
        "data": "data2"
    }
)"_json;

jsonVector.push_back(json1);
jsonVector.push_back(json2);

for (const auto& json : jsonVector) {
    for (auto it = json.begin(); it != json.end(); ++it) {
        mergedJson[it.key()] = it.value();
    }
}

std::cout << mergedJson.dump(4) << std::endl;
