How to embed Go HTML templates into code?
问题
我有一组模板文件，例如base.html、login.html、profile.html、header.html等，它们被组织在文件夹中。
在开发过程中，将它们作为单独的文件是可以的，但是当我部署应用程序时，我希望将它们全部嵌入为字符串，或者解析和编译为模板，以便像往常一样从代码中使用。
我应该如何将这些模板制作为Go代码？这样我就不需要在生产环境中有一个templates文件夹，而是将所有内容都放在单个可执行文件中。
英文:
I have a set of templates as files, like base.html, login.html, profile.html, header.html and so on. They are structured in folders.
It's fine to have them as separate files during development but when I deploy the app, I'd like to have them all embedded as strings or parsed and compiled templates ready to use from the code as usual.
How should I better make these templates as Go code? So that I don't have to have a templates folder in production, but everything in the single executable file?

在Go 1.16中，将会有官方的"embed"包，如果你在2021年2月之后阅读这篇文章，以下内容将成为可能：
//go:embed "mytemplate.tmpl"
var myTemplate string
这段代码在编译时将mytemplate.html嵌入，并作为一个字符串（或者作为[]byte或者作为一个文件系统，如果你愿意）可用。不需要第三方工具或库。
英文:
With Go 1.16 there would be official "embed" package and the following would be possible (is possible if you read this after February 2021):
//go:embed "mytemplate.tmpl"
var myTemplate string
This code embeds mytemplate.html at compile time and it becomes available as a string (or as []byte or as a FileSystem, if you wish). No 3rd-party tools or libraries needed.

最简单的解决方案是在Go源代码中的字符串字面量中嵌入模板。
有一个可以帮助的工具，参见go-bindata。
我在之前的一些项目中使用了go generate来进行这种类型的操作，参见关于go generate命令的博文进行介绍。
英文:
The most simple solution is to embed templates in string literal inside Go source code.
There is a tool that can help, see go-bindata.
I used go generate in some of previous projects for this type of operation, see blog post on go generate command for introduction.

截至Go 1.16版本，引入了//go:embed注释指令。这使得你可以直接将文件嵌入到二进制文件中。
这是关于go embed的Github问题链接，其中包含一些更新
英文:
As of the Go 1.16 release, there is the //go:embed comment directive.
This allows you to directly embed files in your binary.

除了已经提到的go-bindata之外，还有go-bindata-assetfs可以用来从Web服务器上提供静态文件。它适用于JavaScript、CSS等文件。
英文:
In addition to go-bindata which was already mentioned, there is go-bindata-assetfs which you can use to serve static files from a webserver. It's good for Javascript, CSS, etc.
