[{"key":"0","value":"男"},{"key":"1","value":"女"}]转实体map

以下是将[{"key":"0","value":"男"},{"key":"1","value":"女"}]转换为实体map的示例代码：

#include <iostream>
#include <map>
#include <string>
#include <json/json.h>

int main() {
    std::string jsonStr = R"([{"key":"0","value":"男"},{"key":"1","value":"女"}])";
    
    Json::Value root;
    Json::Reader reader;
    if (!reader.parse(jsonStr, root)) {
        std::cout << "Failed to parse JSON string." << std::endl;
        return 1;
    }
    
    std::map<std::string, std::string> entityMap;
    for (const auto& item : root) {
        std::string key = item["key"].asString();
        std::string value = item["value"].asString();
        entityMap[key] = value;
    }
    
    // 输出实体map
    for (const auto& pair : entityMap) {
        std::cout << "Key: " << pair.first << ", Value: " << pair.second << std::endl;
    }
    
    return 0;
}

运行以上代码，将会输出以下结果：

Key: 0, Value: 男
Key: 1, Value: 女
