如何从FTP服务器读取gzip压缩文件？

Question

I want to read file from public FTP server, and can't seem to figure how to use gzip and urllib efficiently, without explicitely downloading the file then opening it with gzip.open() . Is there other way possible at all?

For example " ftp://ftp.server.com/pub/data/archive.gz " is link I got. What is the right way to read the contents from this file in Python?

Edit:

So I ended using:

g = gzip.open(urllib.urlretrieve(url)[0])

Argument to gzip.open() this way is temp file downloaded from url path, and g is now like regular file object representing archive contents

可能的工作是将其读取到内存中，然后将其解压缩，问题是最终将使用大量的内存，因此最好下载而不是将其下载到内存中并从那里进行操作。
