使用Python流将数据从S3传输到FTP服务器

import boto3
import ftplib

s3 = boto3.client('s3')
bucket_name = 'your_bucket_name'
file_name = 'your_file_name'
local_file_path = 'local_file_path_to_save'

s3.download_file(bucket_name, file_name, local_file_path)

ftp_host = 'ftp_server_host'
ftp_user = 'ftp_username'
ftp_password = 'ftp_password'
ftp_directory = 'ftp_directory_to_upload'

ftp = ftplib.FTP(ftp_host)
ftp.login(ftp_user, ftp_password)
ftp.cwd(ftp_directory)

with open(local_file_path, 'rb') as file:
    ftp.storbinary('STOR ' + file_name, file)

import boto3
import ftplib

def transfer_data_from_s3_to_ftp():
    # S3配置
    s3 = boto3.client('s3')
    bucket_name = 'your_bucket_name'
    file_name = 'your_file_name'
    local_file_path = 'local_file_path_to_save'

    # 下载文件
    s3.download_file(bucket_name, file_name, local_file_path)

    # 连接FTP服务器并上传文件
    ftp = ftplib.FTP(ftp_host)
    ftp.login(ftp_user, ftp_password)
