用腾讯混元ai编写了一个go语言端口扫描器

package main
​
import (
    "fmt"
    "net"
    "os"
    "strconv"
    "sync"
    "time"
)
​
func main() {
    if len(os.Args) != 2 {
        fmt.Println("Usage: go run main.go <ip_address>")
        return
    }
​
    ip := os.Args[1]
    if net.ParseIP(ip) == nil {
        fmt.Println("Invalid IP address")
        return
    }
​
    var wg sync.WaitGroup
    for port := 1; port <= 65535; port++ {
        wg.Add(1)
        go func(port int) {
            defer wg.Done()
            address := ip + ":" + strconv.Itoa(port)
            conn, err := net.DialTimeout("tcp", address, 1*time.Second)
            if err != nil {
                return
            }
            defer conn.Close()
            fmt.Printf("Port %d is open\n", port)
        }(port)
    }
​
    wg.Wait()
    fmt.Println("Port scanning finished")
}
