Python根据文件日期从FTP获取文件

from ftplib import FTP
from datetime import datetime
import os

ftp = FTP('ftp.example.com')  # 替换为你的 FTP 服务器地址
ftp.login(user='username', passwd='password')  # 替换为你的用户名和密码

def get_file_date(ftp, filename):
    # 获取文件的详细信息
    response = ftp.sendcmd(f'MDTM {filename}')
    # 解析日期时间字符串
    date_str = response[4:]
    file_date = datetime.strptime(date_str, '%Y%m%d%H%M%S')
    return file_date

# 列出目录中的文件
files = ftp.nlst()

# 过滤出符合日期条件的文件
target_date = datetime(2023, 10, 1)  # 替换为你需要的日期
filtered_files = []

for file in files:
    file_date = get_file_date(ftp, file)
    if file_date.date() == target_date.date():
        filtered_files.append(file)

print("Filtered files:", filtered_files)

def download_file(ftp, filename, local_path):
    with open(local_path, 'wb') as local_file:
        ftp.retrbinary(f'RETR {filename}', local_file.write)

# 下载符合条件的文件
for file in filtered_files:
    local_path = os.path.join('local_directory', file)  # 替换为你的本地目录
    download_file(ftp, file, local_path)
    print(f"Downloaded {file} to {local_path}")
