Golang 实现的通过 QQWry.dat 查找 IP 归属地的库

安装

go get -u github.com/elsejj/qqwry

使用

使用 db

package main
import "github.com/elsejj/qqwry"

func main() {
	path := "qqwry.dat"
	ip   := "183.224.52.133"
	db, err := qqwry.NewDb(path)
	if err != nil {
		country, area := db.Search(ip)
		//TODO: use country area
	}
}

使用 http 服务

package main
import "github.com/elsejj/qqwry"

func main() {
	path := "qqwry.dat"
	addr := "127.0.0.1:8000"
	qqwry.StartHttp(addr, path)
}

则通过 http://127.0.0.1:8000/?ip=183.224.52.133&ip=xxx.xx.xxx.xx
