我如何使用golang的“compress / gzip”包到gzip一个文件？ [英] How can I use golang's "compress/gzip" package to gzip a file?

问题描述

我是golang的新手，不知道如何使用golang的compress / gzip包来获得我的优势。基本上，我只是想写一个文件，gzip它，并直接从压缩格式通过另一个脚本读取它。

I'm new to golang, and can't figure out how to use golang's "compress/gzip" package to my advantage. Basically, I just want to write something to a file, gzip it and read it directly from the zipped format through another script. I would really appreciate if someone could give me an example on how to do this.

推荐答案

所有的压缩包都实现了相同的接口。你将使用这样的东西来压缩：

All the compress packages implement the same interface. You would use something like this to compress:

var b bytes.Buffer
w := gzip.NewWriter(&b)
w.Write([]byte("hello, world\n"))
w.Close()

并解压缩：

r, err := gzip.NewReader(&b)
io.Copy(os.Stdout, r)
r.Close()
