Question

下面的脚本将仅下载ftp站点的文件名而不是我要下载的实际文件，这就是下载后文件大小保持为0的原因。您是否知道导致问题的原因是什么？任何帮助将不胜感激。

import os
from ftplib import FTP
import time


# Connects to remote ftp server
def connect_ftp(hostname, username, password, source_directory, destination_directory):
    os.chdir(destination_directory)

    print("Connecting to " + hostname + "...")
    ftp = FTP(hostname)
    ftp.login(username, password)

    print(ftp.getwelcome())
    print("Connected Successfully!\n")

    ftp.cwd(source_directory)

    download_files(ftp)


# Download files
def download_files(ftp):
    print("This script will only download files, not directories.")
    print("Files at " + source_directory + ":\n")
    ftp.retrlines("LIST")

    file_list = []
    ftp.retrlines("NLST", file_list.append)

    print("")

    i = 0
    for filename in file_list:
        if (filename != '.') and (filename != '..'):
            print("Downloading " + filename + "...")
            try:
                ftp.retrbinary("RETR " + filename, open(filename, "wb").write)
                i=i+1
            except Exception as directory_error:
                print ("Oops! Was " + filename + " a directory? I won't download directories.")

    print(str(i) + " files successfully downloaded.\n")

    disconnect_ftp(ftp)


# Disconnects from ftp server
def disconnect_ftp(ftp):
    print("Disconnecting from " + hostname + "...")    
    ftp.quit()
    print("Disconnected from " + hostname + ".")
    time.sleep(4)


hostname = "ftpsite"                                    # TODO: Replace with the hostname of the server you want to connect to
username = ""                                                       # TODO: Replace the username
password = ""                                                       # TODO: Replace the password
source_directory = "/source/directory/"    # TODO: Change location to wherever you want to start the download
destination_directory = "C:\example\FTP"                            # TODO: Change the location of where you want to download the files to

connect_ftp(hostname, username, password, source_directory, destination_directory)

为什么要使用Python？在* nix系统shell中，运行命令：

wget -r ftp://source/directory

Python - 从ftp目录下载所有文件
