以下是一个使用nlohmann库解析JSON数据,并提取其中的YAML数据,并使用yaml-cpp库解析该YAML数据的示例代码:
#include <iostream>
#include <string>
#include <nlohmann/json.hpp>
#include <yaml-cpp/yaml.h>
using json = nlohmann::json;
int main() {
// JSON字符串
std::string jsonString = R"({
"id": "1.2.31",
"text": "Ensure that the --etcd-cafile argument is set as appropriate (Automated)",
"audit": "/bin/ps -ef | grep ${apiserverbin} | grep -v grep",
"tests": {
"test_items": [
{"flag": "--etcd-cafile"}
]
},
"remediation": "| Follow the Kubernetes documentation and set up the TLS connection between the apiserver and etcd.\nThen, edit the API server pod specification file ${apiserverconf}\non the master node and set the etcd certificate authority file parameter.\n--etcd-cafile=<path/to/ca-file>",
"scored": true
})";
// 解析JSON
json jsonData = json::parse(jsonString);
// 提取YAML数据
std::string yamlData = jsonData["remediation"].get<std::string>();
// 解析YAML数据
YAML::Node yamlNode = YAML::Load(yamlData);
// 输出解析结果
std::cout << "ID: " << jsonData["id"] << std::endl;
std::cout << "Text: " << jsonData["text"] << std::endl;
// 其他字段...
std::cout << "\nRemediation:\n";
for (const auto& line : yamlNode) {
std::cout << line.as<std::string>() << "\n";
}
return 0;
}
请确保已经安装了nlohmann库和yaml-cpp库,并将它们的头文件路径正确包含在项目中。
