开源软件介绍：

Guuid

Guuid 是一款由 Go 语言开发的 UUID 生成服务.

UUID(Universally Unique Identifier)全局唯一标识符,是指在一台机器上生成的数字，它保证对在同一时空中的所有机器都是唯一的。

Guuid使用了服务器主机名、运行的进程ID、时间戳、随机数、时序元素等一系列元素来保证生成UUID的唯一性。

UUID 16 bytes, 构成:

4 bytes 主机名&进程ID
4 bytes 时间戳
4 bytes 计数器
4 bytes 随机数

安装

$ go get -u github.com/dreamans/guuid/guuid-server$ cd $GOPATH/src/github.com/dreamans/guuid/guuid-server$ go install

运行

$GOPATH/bin/guuid-server -port 11223 -timeout 3

Usage:

-port 运行端口-timeout 读写超时时间

运行成功:

⇨ http server started on [::]:11223

RestAPI

获取UUID

$ curl http://127.0.0.1:11223/get{    "code": 200,    "message": "OK",    "uuid": "5d1b3abf-5ab2-2792-0000-00046b2155a4"}

批量获取UUID

$ curl http://127.0.0.1:11223/mget/100{    "code": 200,    "message": "OK",    "data": [        "5d1b3abf-5ab2-27cd-0000-00056d61a5e0",        "5d1b3abf-5ab2-27cd-0000-000648f72a80",        ...    ]}说明:最多返回1000条记录

获取简版UUID
