The file is not compiled, but is accessable from the code at run-time. Embedded resources can be any file type.Languages as JAVA and C# support resources out of box. However, this is not the case for Golang. In order to emebed resource, we need to develop our own solution. Thankfully, there are couple of tools that are doing this for us.参考地址http://blog.ralch.com/tutorial/golang-embedded-resources/go.ricego.rice is a Go package that makes working with resources such as html,js,css,images,templates, etc very easy.github地址https://github.com/GeertJohan/go.riceStar: 1107获取go get github.com/GeertJohan/go.ricego get github.com/GeertJohan/go.rice/rice12FindBoxfuncation to access a particular resource bundler (directory).The function is finding the correct absolute path for your resource files.// find a rice.BoxtemplateBox, err : rice.FindBox(your-resource-directory)if err ! nil { log.Fatal(err)}// get file contents as stringtmpl, err : templateBox.String(your_asset.tmpl)if err ! nil { log.Fatal(err)}12345678910Embedded resource as source code作为源码嵌入资源命令rice embed-go1生成文件.rice-box.go1Embedded resource as an archiveappends a resource as a zip file to already built executable以zip的形式附加到已经存在的可执行文件Embedded resource as an syso resourceThis is experimental method that generates .syso file that is compiled by Go compiler. The following command generates the coff syso resource files per directory:rice embed-syso1go build -o rice append --exec 12echo中使用go.rice代码main.go:package mainimport ( net/http github.com/GeertJohan/go.rice github.com/labstack/echo)func main() { e : echo.New() // the file server for rice. app is the folder where the files come from. assetHandler : http.FileServer(rice.MustFindBox(app).HTTPBox()) // serves the index.html from rice e.GET(/, echo.WrapHandler(assetHandler)) // servers other static files e.GET(/static/*, echo.WrapHandler(http.StripPrefix(/static/, assetHandler))) e.Logger.Fatal(e.Start(:1323))}12345678910111213141516171819202122跟main.go同一级新建一个文件夹app放入文件file.txt执行rice embed-go1生成了 rice-box.gopackage mainimport ( github.com/GeertJohan/go.rice/embedded time)func init() { // define files file2 : embedded.EmbeddedFile{ Filename: file.txt, FileModTime: time.Unix(1511406219, 0), Content: string(), } // define dirs dir1 : embedded.EmbeddedDir{ Filename: , DirModTime: time.Unix(1511406219, 0), ChildFiles: []*embedded.EmbeddedFile{ file2, // file.txt }, } // link ChildDirs dir1.ChildDirs []*embedded.EmbeddedDir{} // register embeddedBox embedded.RegisterEmbeddedBox(app, embedded.EmbeddedBox{ Name: app, Time: time.Unix(1511406219, 0), Dirs: map[string]*embedded.EmbeddedDir{ : dir1, }, Files: map[string]*embedded.EmbeddedFile{ file.txt: file2, }, })}123456789101112131415161718192021222324252627282930313233343536373839404142执行go build1生成文件embed_resources.exe运行embed_resources.exe删除app文件夹下的file.txt浏览器访问http://localhost:1323/可以看到file.txt文件
