golang通过ssh实现远程文件传输

Posted 2022-01-26 -xuzhankun

使用ssh远程操作文件, 主要是创建ssh, 直接上代码

import (
   "fmt"
   "github.com/pkg/sftp"
   "golang.org/x/crypto/ssh"
   "net"
   "strconv"
   "time"
)

func SftpConnect(user, password, host string, port int) (sftpClient *sftp.Client, err error)  //参数: 远程服务器用户名, 密码, ip, 端口
   auth := make([]ssh.AuthMethod, 0)
   auth = append(auth, ssh.Password(password))

   clientConfig := &ssh.ClientConfig
      User:    user,
      Auth:    auth,
      Timeout: 30 * time.Second,
      HostKeyCallback: func(hostname string, remote net.Addr, key ssh.PublicKey) error 
         return nil
      ,
   

   addr := host + ":" + strconv.Itoa(port)
   sshClient, err := ssh.Dial("tcp", addr, clientConfig) //连接ssh
   if err != nil 
      fmt.Println("连接ssh失败", err)
      return
   

   if sftpClient, err = sftp.NewClient(sshClient); err != nil  //创建客户端
      fmt.Println("创建客户端失败", err)
      return
   

   return


使用也很简单

sftpClient.Open() 返回的是*sftp.File, 操作和官方库差不多
