如何使用“ compress / gzip”包gzip文件？ [英] How can I use the "compress/gzip" package to gzip a file?

问题描述

我是Go语言的新手，无法弄清楚如何使用 compress / gzip 软件包对我有利。基本上，我只想写一些东西到文件中，将其gzip压缩，然后通过另一个脚本直接从压缩格式中读取。如果有人可以给我一个有关如何执行此操作的示例，我将不胜感激。

I'm new to Go, and can't figure out how to use the 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compress包都实现相同的接口。您可以使用类似的方法进行压缩：

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()

然后将其解包：

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