使用pysftp的get_r()复制远程目录时遇文件未找到错误

It looks like the error is popping up because the local directory you’re trying to download into doesn’t exist—and pysftp’s get_r method doesn’t automatically create missing local directories. Let’s fix this step by step:

Step 1: Create the Local Directory First #

Add code to generate the local directory (and any missing parent folders) before calling get_r. Use Python’s built-in os.makedirs function for this:

import os
import pysftp

cnopts = pysftp.CnOpts()
cnopts.hostkeys = None

# Use a raw string for Windows paths to avoid escape character headaches
local_path = r'E:\New Folder\FTP Download Folder'
# Create the local directory (and parents) if it doesn't exist
os.makedirs(local_path, exist_ok=True)

# Use a 'with' statement to ensure proper connection cleanup
with pysftp.Connection("10.2.2.99", username="user", password="password", cnopts=cnopts) as p:
    remote_path = '/cradius-data/files/webapps/vcm/somedirectory'
    p.get_r(remotedir=remote_path, localdir=local_path)

Key Improvements: #

• Raw string for Windows path: The r'...' syntax eliminates the need for double backslashes and prevents accidental escape sequence errors.
• Automatic directory creation: os.makedirs(..., exist_ok=True) creates the folder (and any missing parent folders) if it doesn’t exist, without throwing an error if it’s already there.
• Proper connection management: The with statement ensures the SFTP connection is closed automatically after the download finishes, which is a best practice for resource handling.

Step 2: Double-Check the Remote Path #

Just to be thorough, confirm the remote directory actually exists. You can add a quick check to rule out issues on the server side:

with pysftp.Connection("10.2.2.99", username="user", password="password", cnopts=cnopts) as p:
    remote_path = '/cradius-data/files/webapps/vcm/somedirectory'
    if p.isdir(remote_path):
        print("Remote directory found—starting download...")
        p.get_r(remotedir=remote_path, localdir=local_path)
    else:
        print(f"Error: Remote directory {remote_path} doesn't exist")

This will help you confirm whether the problem is with the local or remote path.
