「Golang」将静态文件打包到二进制

智云科技发布于 2022年6月5日评论(28) 阅读(212)

前言：经常写java应用，大家都知道的是打成jar包，把静态文件都直接最后以一个xxx.jar包展现。在运行的时候也特别方便。那么go其实也有这样的操作。

了解目前开源的包

go-bindata
packcr
statik

目前是这三种

开始使用

 #安装 
go get github.com/rakyll/statik
#查看安装结果
statik --help

建立test文件夹，在文件夹内分别建立 main.go和a.json

 #main.go
package main

import (
	_ "./statik"  //注意该包，该包非手动创建，由static命令进行创建
	"fmt"
	"github.com/rakyll/statik/fs"
	"io/ioutil"
	"log"
)

func main() {
	staticFile, err := fs.New()
	if err != nil {
		log.Fatal(err)
	}
	f, err := staticFile.Open("/a.json")
	if err != nil {
		log.Fatal(err)
	}
	defer f.Close()
	contents, err := ioutil.ReadAll(f)
	if err != nil {
		log.Fatal(err)
	}

	fmt.Println(string(contents))
}

 #a.json
{"a": 1}

static命令，将静态文件生成.go的包文件

 #执行static的静态文件转换命令
static -src=./ -include=a.json
# -src默认是public目录
# -include 如果不写，默认目录全部文件
# 执行完上述命令会在当前文件夹产生 static/static.go 此文件就是main.go的注释部分

编译

 #在当前命令行
go build
ls
#执行可执行文件
./test
#结果
{"a": 1}

测试

 #将可执行文件移动到其它地方
mv test /xxxx
#执行
./test
#结果
{"a": 1}

到此就结束了。核心思想在推荐的时候描述了。

总结

快速解决自己想要的，之前使用packcr，这个包宣传的多么好，结果使用起来问题非常多，果断换之。
