Nmap 给出错误消息 "You are running a deprecated option"

Question

我目前正在制作一个应该能够运行的 golang 程序，但出于某种原因，即使我在 cmd 中输入了相同的选项（例如 -oN test.txt），它没有运行并给我这个 error message 这很奇怪，因为在命令行中该行有效但是当我尝试运行它在我的程序中时它没有。

源代码在这里：

package main

import (
    "os/exec"
    "os"
    "fmt"
    "strings"
)
func main(){

    fmt.Println("Please enter which scanner tool you wish to use:")
    fmt.Println("nmap for nmap")

    var toolargs []string
    var ipaddress string
    var toolchoice string

    fmt.Scanln(&toolchoice)

    if toolchoice == "nmap" {
        toolargs = nmap()
        fmt.Println(toolargs)
    }else{
        fmt.Println("invalid input")
    }

    fmt.Println("Please enter the IP address you wish to scan:")
    fmt.Scanln(&ipaddress)  

    fmt.Println(toolchoice)
    fmt.Println(toolargs)
    fmt.Println(ipaddress)

    funccmd(toolchoice, toolargs, ipaddress)

    fmt.Scanln()

}

func nmap() []string{
    var NoOfArgs int
    var args1 string
    var args2 string
    var args3 string
    var args4 string
    var args5 string
    var args []string
    fmt.Println("Please enter a number for how many arguments you wish to use:")
    fmt.Scanln(&NoOfArgs)

    switch NoOfArgs{
    case 1:
            fmt.Println("Please enter your argument")
        fmt.Scanf("%s", &args1)
        args = []string{args1}
    case 2:
            fmt.Println("Please enter your arguments, separated with a blank space between arguments (eg. -sn -sS -O)")
        fmt.Scanf("%s %s", &args1, &args2)
        fmt.Println(args1)
        fmt.Println(args2)
        args = []string{args1, args2}
        fmt.Println(args)

        case 3:
            fmt.Println("Please enter your arguments, separated with a blank space between arguments (eg. -sn -sS -O)")
        fmt.Scanf("%s %s %s", &args1, &args2, &args3)
        args = []string{args1, args2, args3}
    case 4:
        fmt.Println("Please enter your arguments, separated with a blank space between arguments (eg. -sn -sS -O)")
        fmt.Scanf("%s %s %s %s", &args1, &args2, &args3, &args4)
        args = []string{args1, args2, args3, args4}
    case 5: 
        fmt.Println("Please enter your arguments, separated with a blank space between arguments (eg. -sn -sS -O)")
        fmt.Scanf("%s %s %s %s %s", &args1, &args2, &args3, &args4, &args5)
        args = []string{args1, args2, args3, args4, args5}
        }
    fmt.Println(args)
    return args
}

func funccmd(toolchoice string, args []string, ipaddress string){
    execpath, _ := exec.LookPath("/usr/bin/nmap")

    stringargs := strings.Join(args, " ")
    fmt.Println(stringargs)
    final := []string{execpath, stringargs, ipaddress}
    fmt.Println(final)
    cmdNmap := &exec.Cmd{
       Path: execpath,
       Args: []string{execpath, stringargs, ipaddress},
       Stdout: os.Stdout,
       Stderr: os.Stdout,
    }
    fmt.Println(args)
    if err := cmdNmap.Run(); err !=nil{
       fmt.Println("Error", err);
    }   
}

问题是您在将参数传递给 exec.Cmd 之前将它们连接在一起成为一个字符串 (stringargs)。它们都需要是 Args 数组中的一个单独参数。 Nmap 将第一个参数视为“-oN results.txt”，并将其解析为已弃用的选项“-o”和文件名 "N results.txt"。该警告正是为了防止此类错误，因为您很可能不想创建名称为 "N results.txt".
