how to serve static files in golang
问题
我正在尝试在Go语言中创建一个简单的Web服务器，但我不知道如何提供静态CSS文件。这是我的项目结构：
项目文件夹
-> static
-> templates
-> index.gohtml
-> styles
-> style.css
在我的模板中，我有这个简单的HTML行：<link href="/styles/styles.css" type="text/css">
在main.go中，我有以下代码：
http.Handle("/styles", http.FileServer(http.Dir("./static/styles")))
...
// 显示后端主页，引用index.gohtml
http.HandleFunc("/backend/home", handler)
英文:

现在当它们访问/styles时，它会尝试访问./static/styles/styles，所以通常你会去掉前缀，像这样：
http.Handle("/styles/", http.StripPrefix("/styles/", http.FileServer(http.Dir("./static/styles")))))
参考链接：https://pkg.go.dev/net/http#example-FileServer-StripPrefix
英文:
Right now when they hit /styles, it will try and access ./static/styles/styles, so you generally strip the prefix like so:
http.Handle("/styles/", http.StripPrefix("/styles/", http.FileServer(http.Dir("./static/styles"))))
See https://pkg.go.dev/net/http#example-FileServer-StripPrefix

我弄清楚了（只是为了运气）
我必须将这段代码放在 main.go 文件中：
fs := http.FileServer(http.Dir("./static/styles"))
http.Handle("/styles/", http.StripPrefix("/styles", fs))
并且在头部添加以下内容：
<style>
@import url("/styles/style.css");
</style>
否则它不起作用。
英文:
I figured out (just for for luck)
I have to put this on the main.go
fs := http.FileServer(http.Dir("./static/styles"))
http.Handle("/styles/", http.StripPrefix("/styles", fs))
and this on the header:
<style>
@import url("/styles/style.css");
</style>
otherwise it doesn't work
