本文介绍如何使用Ruby语言通过uuidtools库来实现UUID的随机生成。文章详细展示了如何安装uuidtools库，并提供了具体的代码示例来生成不同的UUID字符串。
How to

1 Install
On DOS command , type this

gem install uuidtools

2 require
Add to top line on application.rb
require 'uuidtools'

Let's create 
key = UUID.random_create().to_s>> UUID.random_create().to_s
UUID.random_create().to_s
=> "003b9ae0-0485-11dc-a799-005056c00008"
>> UUID.random_create().to_s
UUID.random_create().to_s
=> "051f4890-0485-11dc-a799-005056c00008"
>> UUID.random_create().to_s
UUID.random_create().to_s
=> "06b48e90-0485-11dc-a799-005056c00008"
>> UUID.random_create().to_s
UUID.random_create().to_s
=> "081ef400-0485-11dc-a799-005056c00008"

GUID 来自百度： 全局唯一标识符（GUID，Globally Unique Identifier）是一种由算法生成的二进制长度为128位的数字标识符。GUID主要用于在拥有多个节点、多台计算机的网络或系统中。在理想情况下，任何计算机和计算机集群都不会生成两个相同的GUID。GUID 的总数达到了2^128（3.4×10^38）个，所以随机生成两个相同GUID的可能性非常小，但并不为0。所以...

一、boost库 #include <boost/uuid/uuid.hpp> #include <boost/uuid/uuid_io.hpp> #include <boost/uuid/uuid_generators.hpp> boost::uuids::uuid my_uuid = boost::uuids::random_generator(); std::string uuid_to_string = boost::uuids::to_string(a_uu

什么是UUID UUID是128位的数字，用来标志属性的类型，服务也是一种属性，也需要UUID 16位的UUID是精简版的，结合UUID基数就可以凑成128位的，标准UUID，厂商自定义UUID都是采用这种模式 0x1800-0x26FF 作为服务通用唯一标识码 0x2700-0x27FF 作为标识计量单位 0x2800-0x28FF 作为区分属性类型 0x2900-0x29FF 作为特征描...

什么是UUID UUID是指（Universally Unique Identifier）通用唯一识别码，128位。RFC 4122描述了具体的规范实现。 UUID作用 UUID 的目的是让分布式系统中的所有元素都能有唯一的识别信息。如此一来，每个人都可以创建不与其它人冲突的 UUID，就不需考虑数据库创建时的名称重复问题。其作用视场景而定。 UUID定义 UUID使用16进制表示，共有36个字符(32个字母数字+4个连接符"-")组成，格式为8-4-4-4-12；【一个16进制只代表4个bi..
