UUID生成实例使用Boost C ++中 [英] Example of UUID generation using Boost in C++

问题描述

我要生成只是随机UUID的，因为它是在我的计划有唯一标识符的实例有重要意义。我看着升压UUID ，但我不能设法生成UUID因为我不知道要使用的类和方法。

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.

我AP preciate如果有人可以给我如何实现这一目标的例子。

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;
}

输出示例：

7feb24af-fc38-44de-bc38-04defc3804de

7feb24af-fc38-44de-bc38-04defc3804de
