golang ssh host 连接华为NE5k路由器并支持more分页符

• 利用golang/x/crypto/ssh实现并参考作者: CodyGuo代码
• 登录华为路由器执行命令display version和display arp statistics all
• 对终端屏宽产生的分页符做处理
• 可用作单台设备执行命令打印输出之用

重点code说明

...
in <- "display version" //执行输入goroutine
in <- "display arp statistics all"
...
go func() {
 for cmd := range in {
 wg.Add(1)
 w.Write([]byte(cmd + "\n"))
 wg.Wait() //控制每次goroutine执行一条命令
 }
 }()
go func() {
 var (
 buf [1024 * 1024]byte
 t int
 )
 for {
 n, err := r.Read(buf[t:])
 if err != nil {
 fmt.Println(err.Error())
 close(in)
 close(out)
 return
 }
 t += n
 result := string(buf[:t])
 //循环处理设备分页符
 if strings.Contains(string(buf[t-n:t]), "More") {
 w.Write([]byte("\n"))
 }
 //匹配等待符完成一条操作清空goroutine
 if strings.Contains(result, "username:") ||
 strings.Contains(result, "password:") ||
 strings.Contains(result, ">") {
 out <- string(buf[:t])
 t = 0
 wg.Done()
 }
 }
 }()
...
