生活随笔
收集整理的這篇文章主要介紹了
go “静态目录服务” http.FileServer
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
參照手冊http://godoc.golangtc.com/pkg/net/http/#FileServer
里面給了Example：
http.Handle("/",?http.FileServer(http.Dir("/tmp")))這個是對目錄提供靜態映射服務，如果是單個文件
http.HandleFunc("/static/",?func(w?http.ResponseWriter,?r?*http.Request)?{http.ServeFile(w,?r,?r.URL.Path[1:])}) })完整例子：
import?("fmt""log""net/http""os""path/filepath" )var?staticMap?map[string]string?=?map[string]string{"/web/":??????????????"../public/web","/bower_components/":?"../public/bower_components", }func?InitStaticServer()?{rootDir,?err?:=?filepath.Abs(filepath.Dir(os.Args[0]))if?err?!=?nil?{log.Fatal(err)}for?webPath,?sysPath?:=?range?staticMap?{sysPath,?err?=?filepath.Abs(fmt.Sprintf("%s/%s/",?rootDir,?sysPath))if?err?!=?nil?{log.Fatal(err)}log.Print("Serving?",?webPath,?"?->?",?sysPath)http.Handle(webPath,?http.StripPrefix(webPath,?http.FileServer(http.Dir(sysPath))))} }package main
import (
??? "fmt"
??? "net/http"
)
func main() {
??? http.HandleFunc("/", homeHandler)
??? http.HandleFunc("/static/", func(w http.ResponseWriter, r *http.Request) {
??????? http.ServeFile(w, r, r.URL.Path[1:])
??? })
??? panic(http.ListenAndServe(":17901", nil))
}
func homeHandler(w http.ResponseWriter, r *http.Request) {
??? fmt.Fprintf(w, "<html><head></head><body><h1>Welcome Home!</h1><a href=\"/static/img/test.gif\">Show Image!</a></body></html>")
}
