How to set Home page and static files in same path
问题
如果我运行URL http://localhost:8080/，我想要运行Index函数。如果我运行http://localhost:8080/robot.txt，它应该显示static文件夹中的文件。
func main() {
http.HandleFunc("/", Index)
http.Handle("/", http.StripPrefix("/", http.FileServer(http.Dir("static"))))
http.ListenAndServe(":8080", nil)
}
func Index(w http.ResponseWriter, r *http.Request) {
fmt.Fprintln(w, "Index")
}
如何实现这个功能？
目前，我遇到了以下错误：
panic: http: multiple registrations for /
这是我的目录结构：
main.go
static\
| robot.txt
| favicon.ico
| sitemap.xml
英文:
if I run the URL http://localhost:8080/ I want to run the Index function and If I run http://localhost:8080/robot.txt it should show static folder files
func main() {
http.HandleFunc("/", Index)
http.Handle("/", http.StripPrefix("/", http.FileServer(http.Dir("static"))))
http.ListenAndServe(":8080", nil)
}
func Index(w http.ResponseWriter, r *http.Request) {
fmt.Fprintln(w, "Index")
}
How to do this.
Currently, I'm getting this error
> panic: http: multiple registrations for /
This is my directory structure
main.go
static\
| robot.txt
| favicon.ico
| sitemap.xml

将索引处理程序委托给文件服务器：
func main() {
http.HandleFunc("/", Index)
http.ListenAndServe(":8080", nil)
}
var fserve = http.StripPrefix("/", http.FileServer(http.Dir("static"))))
func Index(w http.ResponseWriter, r *http.Request) {
if r.URL.Path != "/" {
fserve.ServeHTTP(w, r)
return
}
fmt.Fprintln(w, "Index")
}
将上述代码翻译为中文如下：
func main() {
http.HandleFunc("/", Index)
http.ListenAndServe(":8080", nil)
}
var fserve = http.StripPrefix("/", http.FileServer(http.Dir("static"))))
func Index(w http.ResponseWriter, r *http.Request) {
if r.URL.Path != "/" {
fserve.ServeHTTP(w, r)
return
}
fmt.Fprintln(w, "Index")
}
英文:
Delegate to the file server from the index handler:
func main() {
http.HandleFunc("/", Index)
http.ListenAndServe(":8080", nil)
}
var fserve = http.StripPrefix("/", http.FileServer(http.Dir("static"))))
func Index(w http.ResponseWriter, r *http.Request) {
if r.URL.Path != “/“ {
fserve.ServeHTTP(w, r)
return
}
fmt.Fprintln(w, "Index")
}
