即使使用 SkipClean 后也不接受双斜线

Question

我有以下小程序。即使在使用 SkipClean 之后，它也不接受编码的双斜杠 (%2F%2F)，而单编码的斜杠工作正常。

有人可以建议这里出了什么问题吗？

package main

import (
    "fmt"
    "net/http"
    "github.com/gorilla/mux"
)

func main() {
    r := mux.NewRouter().SkipClean(true).UseEncodedPath()
    r.HandleFunc("/", hiHandler)
    r.HandleFunc("/hi{*}", hiHandler).Methods("GET")
    http.Handle("/", r)
    http.ListenAndServe(":10801", nil)
}

func hiHandler(w http.ResponseWriter, r *http.Request) {
    fmt.Fprint(w, "Hello world!")
}

#curl http://localhost:10801/hi%2Fds => 这有效

#curl http://localhost:10801/hi%2F%2Fds => 这不是。给出永久移动错误。

诀窍是以稍微不同的方式运行服务器。

package main

import (
    "fmt"
    "github.com/gorilla/mux"
    "log"
    "net/http"
    "time"
)

func main() {
    r := mux.NewRouter().SkipClean(true).UseEncodedPath()
    r.HandleFunc("/", hiHandler)
    r.HandleFunc("/hi{*}", hiHandler).Methods("GET")

    srv := &http.Server{
        Handler: r,
        Addr:    "localhost:10801",
        // Good practice: enforce timeouts for servers you create!
        WriteTimeout: 15 * time.Second,
        ReadTimeout:  15 * time.Second,
    }

    log.Fatal(srv.ListenAndServe())
}

func hiHandler(w http.ResponseWriter, r *http.Request) {
    // Putting the match of {*} into the output
    v := mux.Vars(r)
    fmt.Fprint(w, "Hello world! ", v["*"])
}

curl http://localhost:10801/hi%2Fds将输出Hello world! %2Fds
curl http://localhost:10801/hi%2F%2Fds将输出Hello world! %2F%2Fds。
