在 C++ 中使用 Boost 生成 UUID 的示例

2021-12-24 00:00:00 uuid c++ boost boost-uuid

我只想生成随机的 UUID，因为对于我的程序中的实例来说具有唯一标识符非常重要.我查看了 Boost UUID，但我不能设法生成了 UUID，因为我不明白要使用哪个类和方法.

I want to generate just random UUID's, as it is just important for instances in my program to have unique identifiers. I looked into Boost UUID, but I can't manage to generate the UUID because I don't understand which class and method to use.

如果有人能给我任何如何实现这一目标的例子，我将不胜感激.

I would appreciate if someone could give me any example of how to achieve this.

推荐答案

一个基本的例子:

#include <boost/uuid/uuid.hpp>            // uuid class
#include <boost/uuid/uuid_generators.hpp> // generators
#include <boost/uuid/uuid_io.hpp>         // streaming operators etc.

int main() {
    boost::uuids::uuid uuid = boost::uuids::random_generator()();
    std::cout << uuid << std::endl;
}

示例输出:
