问题
你好,我想创建一个 Web 服务器,它使用一个路由器和一个子路由器来呈现 2 个页面和 2 个静态目录。
我无法理解为什么在子路由器处理的静态服务器不工作时显示路由器提供的静态目录。
代码、文件系统方案和网页:显示和想要的如下所示。
文件系统方案
ProjectFolder/
testFile
test.go
代码
package main
import (
"github.com/gorilla/mux"
"net/http"
)
func index(w http.ResponseWriter, r *http.Request) {
w.Write([]byte("Index"));
}
func main () {
r := mux.NewRouter()
sub := r.PathPrefix("/sub").Subrouter()
r.HandleFunc("/", index)
r.Handle("/static", http.StripPrefix("/static", http.FileServer(http.Dir("./"))))
sub.Handle("/static", http.StripPrefix("/static", http.FileServer(http.Dir("./"))))
sub.HandleFunc("/", index)
http.ListenAndServe(":8080", r)
}
我想要在网络服务器中的页面
http://localhost:8080/ ----> (index)
http://localhost:8080/static ---> (presentation of the file systemfolder)
http://localhost:8080/sub/ ---> (index)
http://localhost:8080/sub/static ---> (presentation of the file system folder)
我在网络服务器上的页面
http://localhost:8080/ ----> (index)
http://localhost:8080/static ---> (presentation of the file system folder)
http://localhost:8080/sub/ ---> (index)
http://localhost:8080/sub/static ---> (404 page not found)
最佳答案
尝试将子文件服务器行更改为(在 StripPrefix 调用中包含 sub
路径)
sub.Handle("/static", http.StripPrefix("/sub/static", http.FileServer(http.Dir("./"))))
下面的代码适合我
package main
import (
"net/http"
"github.com/gorilla/mux"
)
func index(w http.ResponseWriter, r *http.Request) {
w.Write([]byte("Index"))
}
func main() {
r := mux.NewRouter()
r.Handle("/static", http.StripPrefix("/static", http.FileServer(http.Dir("./"))))
r.HandleFunc("/", index)
sub := r.PathPrefix("/sub").Subrouter()
sub.Handle("/static", http.StripPrefix("/sub/static", http.FileServer(http.Dir("./"))))
sub.HandleFunc("/", index)
http.ListenAndServe(":8080", r)
}
关于http - 带有静态文件的 Go Gorilla mux 子路由器,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/51010538/
