golang实现版本号比较

写一下，好久没更新博客了。

import (
    "fmt"
    "strings"
    "testing"
    "time"
)

/**
*Created by 908204694@qq.com 
*/

//版本号大
const VersionBig = 1

//版本号小
const VersionSmall = 2

//版本号相等
const VersionEqual = 0

func Test_version(t *testing.T) {

    versionA := "1.2.3a"
    versionB := "1.2.3b"
    fmt.Println(compareStrVer(versionA, versionB))

    time.LoadLocation("Local")
    fmt.Println(time.Now())
}

func compareStrVer(verA, verB string) int {

    verStrArrA := spliteStrByNet(verA)
    verStrArrB := spliteStrByNet(verB)

    lenStrA := len(verStrArrA)
    lenStrB := len(verStrArrB)

    if lenStrA != lenStrB {
        panic("版本号格式不一致")

    }

    return compareArrStrVers(verStrArrA, verStrArrB)
}
