golang通过FTP上传并同时获得FTP进度

fileName := "sth"
var err error
var ftp *goftp.FTP

if ftp,err = goftp.Connect("serverip:port"); err != nil {
    fmt.Println(err)
}

defer ftp.Close()

config := tls.Config{
    InsecureSkipVerify: true,ClientAuth:         tls.RequestClientCert,}

if err = ftp.AuthTLS(config); err != nil {
    //      log.Println("1",err)
}

if err = ftp.Login("userName","pass"); err != nil {
    log.Println("2",err)
}
//
if err = ftp.Cwd("/home/myDir/"); err != nil {
    log.Println("3",err)
}

var file *os.File
if file,err = os.Open(fileName); err != nil {
    log.Println("6",err)
}
defer file.Close()

fmt.Println("start")

go func() {
    fmt.Println("first")
    nmp := ftp.Stor(fileName,file)
    if nmp != nil {
        log.Println("7",err)
    } else {
        fmt.Println("first is runung")

    }
}()

go func() {
    fmt.Println("second")
    for {
        files,nms := ftp.List(fileName)
        if nms == nil {
            fmt.Println(files)
        }
        time.Sleep(1 * time.Second)
    }
}()

fmt.Println("end")

var mnmn string
fmt.Scan(&mnmn)

ftp.Stor func将无法运行,我的代码返回低于输出：
