golang ssh host 串連華為NE5k路由器並支援more分頁符

• 利用golang/x/crypto/ssh實現並參考作者: CodyGuo代碼
• 登入華為路由器執行命令display version和display arp statistics all
• 對終端屏寬產生的分頁符做處理
• 可用作單台裝置執行命令列印輸出之用

重點code說明

...in <- "display version"  //執行輸入goroutinein <- "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執行一條命令        }    }()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])            //迴圈處理裝置分頁符            if strings.Contains(string(buf[t-n:t]), "More") {                w.Write([]byte("\n"))            }            //匹配等待符完成一條操作清空goroutine            if strings.Contains(result, "username:") ||                strings.Contains(result, "password:") ||                strings.Contains(result, ">") {                out <- string(buf[:t])                t = 0                wg.Done()            }        }    }()...
