urlshorter

golang url shorter like t.co,t.cn and so on.

Use uint64 id and convert it to 62 decimal string .

You should save origURL ,id and the 62 decimal string as shortURL by yourself.

install

go get -u -v github.com/brucemaclin/urlshorter

use

you can use without DB,but only use shortURLGene and GetID by short URL.

example:

    package main
    import (
        "github.com/brucemaclin/urlshorter"
        "math/rand"
        "fmt"
    )

    func main() {
        id := rand.Uint64()
        shortURL := urlshorter.ShorterURLGene(id)
        fmt.Println("shortURL for id:", shortURL)

    }

if use with db,you should implement the urlshorter.DB interface.

see DefaultDB in db.go .

you can use mysql/redis/mongo as your wish.

you can try with demo.

    go run demo.go

then you can type http://127.0.0.1:8080/?url=www.google.com,it will return a shorter url.
