1 recently in writing SFTP upload file, read a pile of code on the Internet, a lot of experiments, always unsuccessful, here to inquire
func Sftp_connect(user, pbi, local string) {
fmt.Println(user, pbi, local)
pub := PublicKeyFile(pbi)
sshConfig := &ssh.ClientConfig{
User: user,
Auth: []ssh.AuthMethod{
pub,
},
HostKeyCallback: func(hostname string, remote net.Addr, key ssh.PublicKey) error {
return nil
},
}
conn, err := ssh.Dial("tcp", local, sshConfig)
if err != nil {
fmt.Println("sulwan")
fmt.Println(err)
} else {
fmt.Println(conn)
defer conn.Close()
}
} error:
panic: runtime error: invalid memory address or nil pointer dereference

for answers to the above questions, it is best to find a complete example of SFTP pubkey authentication upload
