python使用ftputil同步远程目录实例代码

import os
from datetime import datetime, timedelta

import ftputil


def sync_ftp_to_local(remote_dir, local_dir, ftp_host, ftp_username, ftp_password):
    # 连接FTP服务器
    ftp = ftputil.FTPHost(ftp_host, ftp_username, ftp_password)

    # 获取最近三天的日期
    three_days_ago = datetime.now() - timedelta(days=365)

    # 遍历远程目录
    for root, dirs, files in ftp.walk(remote_dir):
        for filename in files:
            # 获取文件的完整路径
            remote_path = ftp.path.join(root, filename)

            # 获取文件的修改时间
            modified_time = ftp.path.getmtime(remote_path)

            # 检查文件是否是txt扩展名且在最近三天内修改过
            if datetime.fromtimestamp(modified_time) > three_days_ago:
                # 构建本地目录和文件路径
                local_path = os.path.join(local_dir, os.path.relpath(remote_path, remote_dir))

                # 创建本地目录
                os.makedirs(os.path.dirname(local_path), exist_ok=True)

                # 下载文件
                ftp.download(remote_path, local_path)

    # 关闭FTP连接
    ftp.close()


# 示例用法
remote_path = "/root"
local_path = "D:/TestWorkspace/ftp_sync"
ftp_host = "192.168.1.50"
ftp_username = "root"
ftp_password = "password"

sync_ftp_to_local(remote_path, local_path, ftp_host, ftp_username, ftp_password)

import os
import ftputil
from datetime import datetime, timedelta

def sync_ftp_subdirectories_to_local(remote_dir, local_dir):
    # 连接FTP服务器
    ftp = ftputil.FTPHost('ftp.example.com', 'username', 'password')

    # 获取最近三天的日期
    three_days_ago = datetime.now() - timedelta(days=3)

    # 获取远程目录下的第一层级子目录
    subdirectories = ftp.listdir(remote_dir)

    # 遍历子目录
    for subdir in subdirectories:
        # 构建子目录的完整路径
        remote_subdir = ftp.path.join(remote_dir, subdir)

        # 检查子目录是否存在
        if ftp.path.isdir(remote_subdir):
            # 遍历子目录下的文件
            for filename in ftp.listdir(remote_subdir):
                # 获取文件的完整路径
                remote_path = ftp.path.join(remote_subdir, filename)

                # 获取文件的修改时间
                modified_time = ftp.path.getmtime(remote_path)

                # 检查文件是否是txt扩展名且在最近三天内修改过
                if filename.endswith('.txt') and datetime.fromtimestamp(modified_time) > three_days_ago:
                    # 构建本地目录和文件路径
                    local_path = os.path.join(local_dir, subdir, filename)

                    # 创建本地目录
                    os.makedirs(os.path.dirname(local_path), exist_ok=True)

                    # 下载文件
                    ftp.download(remote_path, local_path)

    # 关闭FTP连接
    ftp.close()

# 调用函数进行同步
sync_ftp_subdirectories_to_local('/remote/ftp/dir', '/local/dir')
