示例

func main() {
    q, err := ip.New(ip.WithMemoryMode("./qqwry.dat"))
    if err != nil {
        panic(err)
    }
    r, err := q.Query("1.0.0.1")
    if err != nil {
        panic(err)
    }
    
    fmt.Printf("国家: %s\n地区: %s\n合并: %s\n", r.Country, r.Region, r.Location)
    fmt.Printf("IP库版本号: %s", q.Version())
}

并发安全

使用goroutine模拟并发未发生竟态

测试

内存模式下单次查询为10微秒级别，文件模式下单次查询为100微秒级别
