Subrouter与negroni / gorilla mux的问题

所以我尝试设置路由器以响应/users/users/{userId},所以我尝试了这段代码:

usersRouter := router.PathPrefix("/users").Subrouter()
usersRouter.HandleFunc("", users.GetUsersRoute).Methods("GET")
usersRouter.HandleFunc("/{userId:[0-9]*}", users.GetUserRoute).Methods("GET")

问题是,当我转到/users时,我收到了404错误(但确实回复了/users/)如果我这样做:

router.HandleFunc("/users", users.GetUsersRoute).Methods("GET")
router.HandleFunc("/users/{userId:[0-9]*}", users.GetUserRoute).Methods("GET")

它就像我想要的那样。

有没有办法让网址像Subrouters一样工作?

是和否。您可以通过将StrictSlash(true)添加到路由器来使路由半工作。

给出以下代码

package main

    import (
        "fmt"
        "net/http"

        "github.com/gorilla/mux"
    )

    func main() {
        mainRouter := mux.NewRouter().StrictSlash(true)
        mainRouter.HandleFunc("/test", func(w http.ResponseWriter, r *http.Request) { fmt.Fprint(w, "test") })

        subRouter := mainRouter.PathPrefix("/users").Subrouter()
        subRouter.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) { fmt.Fprint(w, "/users") })
        subRouter.HandleFunc("/{id:[0-9]+}", func(w http.ResponseWriter, r *http.Request) { fmt.Fprint(w, "/users/id") })
        http.ListenAndServe(":8080", mainRouter)
    }

http://localhost:8080/users的请求将返回

< HTTP/1.1 301 Moved Permanently
< Location: /users/
< Date: Tue, 07 Apr 2015 19:52:12 GMT
< Content-Length: 42
< Content-Type: text/html; charset=utf-8
< 
<a href="/users/">Moved Permanently</a>.

http://localhost:8080/users/的请求返回

< HTTP/1.1 200 OK
< Date: Tue, 07 Apr 2015 19:54:43 GMT
< Content-Length: 6
< Content-Type: text/plain; charset=utf-8

< /users

因此,如果您的客户是浏览器,那么也许这是可以接受的。
