Question

如何打开和FTP网址并将其下载到文件中。我正在尝试的东西看起来像这样：

from contextlib import closing
from urllib.request import urlopen

url = 'ftp://whatever.com/file.txt'
target_path = 'file.txt'

with closing(urlopen(url)) as source:
    with open(target_path, 'wb') as target:
        target.write(source)

然而，这失败并出现以下错误：

TypeError: 'addinfourl' does not support the buffer interface

有没有简单的方法让这项工作？特别是如果我想扩展它，以便在下载文件时提取文件？

write需要具有缓冲区接口的对象，特别是bytes，但source实际上是BufferedReader（如果是http，则为HTTPResonse。要获取字节，您需要调用BufferedReader.read()

from contextlib import closing
from urllib.request import urlopen

url = 'ftp://whatever.com/file.txt'
target_path = 'file.txt'

with closing(urlopen(url)) as source:
    with open(target_path, 'wb') as target:
        target.write(source.read())

Python打开FTP url并写入文件
