golang通過ssh實現遠程文件傳輸

使用ssh遠程操作文件, 主要是創建ssh, 直接上代碼

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) { //參數: 遠程服務器用戶名, 密碼, 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) //連接ssh
   if err != nil {
      fmt.Println("連接ssh失敗", err)
      return
   }

   if sftpClient, err = sftp.NewClient(sshClient); err != nil { //創建客戶端
      fmt.Println("創建客戶端失敗", err)
      return
   }

   return
}

使用也很簡單

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