golang包装静态资源3种方式

需求场景

有时候golang打包一个web应用，想html,js,css等也一并打包进去成一个二进制文件，方便做分发

常见的工具

gobindata

https://github.com/go-bindata/go-bindata

[root@workpc ~]# go-bindata -o myfile.go data/

data, err := Asset("pub/style/foo.css")
if err != nil {
    // Asset was not found.
}

// use asset data

statik

https://github.com/rakyll/statik

[root@workpc ~]#go get github.com/rakyll/statik

[root@workpc ~]#statik -src=/path/to/your/project/public

import (
  "github.com/rakyll/statik/fs"

  _ "./statik" // 替换成你刚才生成目录的路径
)

  // ...

  statikFS, err := fs.New()
  if err != nil {
    log.Fatal(err)
  }
  
  // Serve the contents over HTTP.
  http.Handle("/public/", http.StripPrefix("/public/", http.FileServer(statikFS)))
  http.ListenAndServe(":8080", nil)

embedDoc

import "embed"


// content 就是我们的静态资源
//go:embed image/* template/*
//go:embed html/index.html
var content embed.FS

//go:embed hello.txt
var s string
print(s)

//go:embed hello.txt
var b []byte
print(string(b))

//go:embed hello.txt
var f embed.FS
data, _ := f.ReadFile("hello.txt")
print(string(data))
