There is no “out of the box” support for gzip-compressed HTTP responses yet. But adding it is pretty trivial. Have a look at

The New York Times have released their <a href="https://github.com/NYTimes/gziphandler" rel="noreferrer">gzip middleware package for Go</a>.

You just pass your <code>http.HandlerFunc</code> through their <code>GzipHandler</code> and you're done. It looks like this:

<pre><code>package main

import (
 "io"
 "net/http"
 "github.com/nytimes/gziphandler"
)

func main() {
 withoutGz := http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
 w.Header().Set("Content-Type", "text/plain")
 io.WriteString(w, "Hello, World")
 })

 withGz := gziphandler.GzipHandler(withoutGz)

 http.Handle("/", withGz)
 http.ListenAndServe("0.0.0.0:8000", nil)
}
</code></pre>

For the sake of completeness, I eventually answered my own question with a handler that is simple and specialises in solving this issue.

This serves static files from a Go http server, including the asked-for performance-enhancing features. It is based on the standard net/http ServeFiles, with gzip/brotli and cache performance enhancements.

There is yet another "out of the box" middleware now, supporting <code>net/http</code> and Gin:

<a href="https://github.com/nanmu42/gzip" rel="nofollow noreferrer">https://github.com/nanmu42/gzip</a>

<code>net/http</code> example:

<pre class="lang-golang prettyprint-override"><code>import github.com/nanmu42/gzip

func main() {
 mux := http.NewServeMux()
 mux.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
 writeString(w, fmt.Sprintf("This content is compressed: l%sng!", strings.Repeat("o", 1000)))
 })

 // wrap http.Handler using default settings
 log.Println(http.ListenAndServe(fmt.Sprintf(":%d", 3001), gzip.DefaultHandler().WrapHandler(mux)))
}

func writeString(w http.ResponseWriter, payload string) {
 w.Header().Set("Content-Type", "text/plain; charset=utf8")
 _, _ = io.WriteString(w, payload+"\n")
}
</code></pre>

Gin example:

<pre class="lang-golang prettyprint-override"><code>import github.com/nanmu42/gzip

func main() {
 g := gin.Default()

 // use default settings
 g.Use(gzip.DefaultHandler().Gin)

 g.GET("/", func(c *gin.Context) {
 c.JSON(http.StatusOK, map[string]interface{}{
 "code": 0,
 "msg": "hello",
 "data": fmt.Sprintf("l%sng!", strings.Repeat("o", 1000)),
 })
 })

 log.Println(g.Run(fmt.Sprintf(":%d", 3000)))
}
</code></pre>

I'm starting to write server-side applications in Go. I'd like to use the <code>Accept-Encoding</code> request header to determine whether to compress the response entity using <code>GZIP</code>. I had hoped to find a way to do this directly using the <code>http.Serve</code> or <code>http.ServeFile</code> methods.
This is quite a general requirement; did I miss something or do I need to roll my own solution?

我开始用Go编写服务器端应用程序。我想使用Accept-Encoding请求头来确定是否使用GZIP压缩响应实体。我曾希望找到一种直接使用http.Serve或http.ServeFile方法来完成此任务的方法。这是一个相当普遍的需求；我是否遗漏了什么，或者我是否需要推出我自己的解决方案？
