我正在尝试使用Gorilla工具包的mux
package来路由Go Web服务器中的URL。使用this question作为指南,我有以下Go代码:
func main() {
r := mux.NewRouter()
r.Handle("/", http.FileServer(http.Dir("./static/")))
r.HandleFunc("/search/{searchTerm}", Search)
r.HandleFunc("/load/{dataId}", Load)
http.Handle("/", r)
http.ListenAndServe(":8100", nil)
}
目录结构是:
...
main.go
static\
| index.html
| js\
| <js files>
| css\
| <css files>
index.html
中引用了Javascript和CSS文件,如下所示:
...
<link rel="stylesheet" href="css/redmond/jquery-ui.min.css"/>
<script src="js/jquery.min.js"></script>
...
当我在网络浏览器中访问http://localhost:8100
时,index.html
内容已成功发送,但是,所有js
和css
网址都会返回404。
如何让程序从static
子目录中提供文件?

我想你可能在寻找PathPrefix
...
func main() {
r := mux.NewRouter()
r.HandleFunc("/search/{searchTerm}", Search)
r.HandleFunc("/load/{dataId}", Load)
r.PathPrefix("/").Handler(http.FileServer(http.Dir("./static/")))
http.ListenAndServe(":8100", r)
}

经过大量的反复试验,上述两个答案都帮助我找到了对我有用的东西。我在web应用程序的根目录中有静态文件夹。
与PathPrefix
一起,我必须使用StripPrefix
来递归地使用路由。
package main
import (
"log"
"net/http"
"github.com/gorilla/mux"
)
func main() {
r := mux.NewRouter()
s := http.StripPrefix("/static/", http.FileServer(http.Dir("./static/")))
r.PathPrefix("/static/").Handler(s)
http.Handle("/", r)
err := http.ListenAndServe(":8081", nil)
}
我希望它有助于其他人遇到问题。

我这里的代码非常好,并且可以重复使用。
func ServeStatic(router *mux.Router, staticDirectory string) {
staticPaths := map[string]string{
"styles": staticDirectory + "/styles/",
"bower_components": staticDirectory + "/bower_components/",
"images": staticDirectory + "/images/",
"scripts": staticDirectory + "/scripts/",
}
for pathName, pathValue := range staticPaths {
pathPrefix := "/" + pathName + "/"
router.PathPrefix(pathPrefix).Handler(http.StripPrefix(pathPrefix,
http.FileServer(http.Dir(pathValue))))
}
}
router := mux.NewRouter()
ServeStatic(router, "/static/")

试试这个:
fileHandler := http.StripPrefix("/static/", http.FileServer(http.Dir("/absolute/path/static")))
http.Handle("/static/", fileHandler)

这为文件夹标志内的所有文件提供服务,并在根目录下提供index.html。
//port default values is 8500
//folder defaults to the current directory
go run main.go
//your case, dont forget the last slash
go run main.go -folder static/
//dont
go run main.go -folder ./
package main
import (
"flag"
"fmt"
"net/http"
"os"
"strconv"
"strings"
"github.com/gorilla/handlers"
"github.com/gorilla/mux"
"github.com/kr/fs"
)
func main() {
mux := mux.NewRouter()
var port int
var folder string
flag.IntVar(&port, "port", 8500, "help message for port")
flag.StringVar(&folder, "folder", "", "help message for folder")
flag.Parse()
walker := fs.Walk("./" + folder)
for walker.Step() {
var www string
if err := walker.Err(); err != nil {
fmt.Fprintln(os.Stderr, "eroooooo")
continue
}
www = walker.Path()
if info, err := os.Stat(www); err == nil && !info.IsDir() {
mux.HandleFunc("/"+strings.Replace(www, folder, "", -1), func(w http.ResponseWriter, r *http.Request) {
http.ServeFile(w, r, www)
})
}
}
mux.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
http.ServeFile(w, r, folder+"index.html")
})
http.ListenAndServe(":"+strconv.Itoa(port), handlers.LoggingHandler(os.Stdout, mux))
}
