如何嵌入文件供以后解析执行使用 [英] How to embed file for later parsing execution use

问题描述

我基本上是在尝试浏览一个包含 html 文件的文件夹.我想将它们嵌入到二进制文件中，并能够根据模板执行的要求解析它们.(如果我措辞不当，请见谅).

I am essentially trying to walk through a folder of html files. I want to embed them into the binary file and be able to parse them upon request for template execution purposes. (Please excuse me if im not wording this properly).

非常感谢您提供任何想法、技巧、技巧或更好的方法来实现这一目标.

Any ideas, tips, tricks or better way of accomplishing this is much appreciated.

// Template Files
type TempFiles struct {
    Files map[string]string
}

// Loop through view files and load them
func LoadTempFiles() {
    t := new(TempFiles)

    // Load template files
    filepath.Walk("application/views", func(path string, info os.FileInfo, err error) error {
    if !info.IsDir() {
        content, _ := ioutil.ReadFile(path)
        t.Files[path] = string(content)
    }
    return nil
    })
}

func ViewTemp(w http.ResponseWriter, path string) {
    t := new(TempFiles)

    temp, err := template.New().Parse(t.Files[path])
    if err != nil {
        http.Error(w, err.Error(), http.StatusInternalServerError)
    } else {
        temp.Execute(w, nil)
    }
}

推荐答案

Go 现在已经内置支持:

Go now has builtin support for this:

package main

import (
   "embed"
   "os"
)

//go:embed *.html
var content embed.FS

func main() {
   b, e := content.ReadFile("index.html")
   if e != nil {
      panic(e)
   }
   os.Stdout.Write(b)
}
