golang-windows开发根据指定端口号查找并kill进程

需求：

window下golang程序开发，希望根据指定端口号查找对应的进程id并kill调该进程。

代码

依赖库安装

go get golang.org/x/text/encoding/simplifiedchinese

package main

	"errors"
	"fmt"
	"golang.org/x/text/encoding/simplifiedchinese"

// KillProcessByPort 根据端口找到服务并杀死对应进程
func KillProcessByPort(port int) (string, error) {
    
    
	c1 := exec.Command("powershell.exe", "netstat", "-ano", "| findstr", strconv.Itoa(port), "| findstr", "LISTENING")
	output, err := c1.CombinedOutput()
	if err != nil {
    
    
		return "", err
	}
	decodeBytes, _ := simplifiedchinese.GB18030.NewDecoder().Bytes(output)
	strNetstat := string(decodeBytes)

	Pid := "0"
