### 使用Python通过FTP或SMB协议保存文件 #### FTP 协议实现方法 为了使用 Python 将文件上传至 FTP 服务器，`ftplib` 是标准库中的一个模块，它提供了简单的接口来处理 FTP 文件传输。 ```python from ftplib import FTP def upload_file_via_ftp(ip_address, username, password, local_filepath, remote_filepath): with FTP(ip_address) as ftp: ftp.login(user=username, passwd=password) with open(local_filepath, 'rb') as file: ftp.storbinary(f'STOR {remote_filepath}', file) upload_file_via_ftp('192.168.31.2', 'username', 'password', '/path/to/local/file.txt', '/path/on/server/file.txt') ``` 此代码片段展示了如何利用 `ftplib` 进行基本的身份验证并上传文件到远程位置[^1]。 #### SMB 协议实现方法 对于 SMB 协议的支持，在 Windows 上通常推荐使用 `pysmbclient` 或者更常用的第三方包如 `smbprotocol` 来完成这项工作。这里给出基于 `smbprotocol` 的例子： 首先安装依赖项： ```bash pip install smbprotocol[kerberos] ``` 接着编写脚本执行文件上传操作： ```python import os from smbprotocol.connection import Connection from smbprotocol.session import Session from smbprotocol.tree import TreeConnect from smbprotocol.open import Open, CreateDisposition, FilePipePrinterAccessMask from smbprotocol.create_contexts import Smb2CreateContextRequest, CreateContextName def upload_file_via_smb(server_ip, share_name, username, password, domain, source_path, destination_path): connection = Connection(uuid.uuid4(), server_ip, 445) connection.connect() session = Session(connection, username, password, domain=domain) session.authenticate() tree = TreeConnect(session, f'\\\\{server_ip}\\{share_name}') tree.connect() create_disposition = CreateDisposition.FILE_OVERWRITE_IF access_mask = FilePipePrinterAccessMask.GENERIC_READ | FilePipePrinterAccessMask.GENERIC_WRITE with open(source_path, "rb") as src_file: data_to_write = src_file.read() with Open(tree, destination_path, desired_access=access_mask, creation_disposition=create_disposition) as opened_file: opened_file.write(data_to_write) upload_file_via_smb( ip_address='192.168.31.2', share_name='personal_folder', username='your_username', password='your_password', domain='', source_path='/local/path/to/sourcefile.txt', destination_path='/remote/path/destinationfile.txt' ) ``` 这段代码说明了怎样建立与 SMB 服务器的安全连接，并将本地文件写入目标路径中[^3]。
