c++ yaml-cpp库解析yaml

1.config.yaml

username: helen
password: 123456

2.源码实现

#include <iostream>
#include <yaml-cpp/yaml.h>

using namespace std;

int main()
{
    YAML::Node config = YAML::LoadFile("config.yaml");

    const std::string username = config["username"].as<std::string>();
    const std::string password = config["password"].as<std::string>();

    cout << username << endl;
    cout << password << endl;

    return 0;
}

3.编译源码

$ g++ -o test test.cpp -std=c++11 -lyaml-cpp

4.运行及其结果

$ ./test
helen
123456
