How to Transfer Pandas DataFrame to .csv on SFTP using Paramiko Library in Python?

问题

I want to transfer a Python dataframe directly as a .csv file to a remote server using Paramiko module. Currently, I save the dataframe as a .csv then I push that .csv file to the server. I stumbled by this similar question How to write pandas dataframe to csv/xls on FTP directly, but is it possible using Paramiko module? Thanks in advance!

This is the simple script I use to transport a .csv file from my directory to the remote server:

import pandas as pd
import paramiko

# Save DataFrame as CSV
file_name = 'file.csv'
df.to_csv(file_name,index=False)

# Connect to Server Via FTP
ssh_client = paramiko.SSHClient()
ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh_client.connect(hostname='host',username='user_name',password='password')
ftp_client= ssh_client.open_sftp()

# Upload 'file.csv' to Remote Server
ftp_client.put('path_to_file.csv','path_to_remote_file')

回答1:

Just use SFTPClient.open

with sftp.open('path_to_remote_file', "w") as f:
    f.write(df.to_csv(index=False))
