Hi there!
Let's start reading the PEM file:
/// Read the PEM file.
pemContentBytes, err := ioutil.ReadFile("google_reserve")
if err != nil {
log.Fatal(err)
}
password := "123456"
/// Parse private key with passphrash
signer, err := ssh.ParsePrivateKeyWithPassphrase(pemContentBytes, []byte(password))
if err != nil {
log.Fatalf("SSH PARSE PRIVATE KEY WITH PASSPHRASE FAILED:%v", err)
}
We have ssh signer so next step is to set up the client with that signer.
username := "replace_with_sftp_username"
sftpURL := "replace_with_sftp_url"
clientConfig := &ssh.ClientConfig{
User: username,
Auth: []ssh.AuthMethod{ssh.PublicKeys(signer)},
HostKeyCallback: ssh.InsecureIgnoreHostKey(),
}
conn, err := ssh.Dial("tcp", sftpURL, clientConfig)
if err != nil {
log.Fatalf("SSH DIAL FAILED:%v", err)
}
defer conn.Close()
Now we can start the client to work with the SFTP connection:
// Create new SFTP client
sftpNewClient, err := sftp.NewClient(conn)
if err != nil {
log.Fatalf("SFTP NEW CLIENT FAILED:%v\n", err)
}
defer sftpNewClient.Close()
Below an example how to upload a file:
fileName := "replace_with_filename.extension"
sourceFile, err := os.Open(fileName)
if err != nil {
return
}
defer sourceFile.Close()
destinationFile, err := sftpNewClient.OpenFile(fileName, os.O_WRONLY|os.O_CREATE|os.O_TRUNC)
if err != nil {
log.Fatalf("OS OPEN FILE FAILED: %v\n", err)
}
defer destinationFile.Close()
_, err = io.Copy(destinationFile, sourceFile)
if err != nil {
log.Fatalf("IO COPY FAILED: %v\n", err)
}
It's done :)
