Gorilla Mux 子路由方法 POST 请求触发 GET

Question

我正在尝试使用 Gorilla Mux 在 Go 中开发一个简单的 REST API。

我有 main.go 注册上面的简单路径并启动服务器以侦听端口 3000.

func main() {
    router := mux.NewRouter().StrictSlash(true)
    sub := router.PathPrefix("/api/v1").Subrouter()
    handlers.RegisterRoutes(sub)

    log.Fatal(http.ListenAndServe(":3000", router))
}

另一个通用 handlers.go 文件中的基本处理程序注册方法

func RegisterRoutes(sub *mux.Router) {
    user.RegisterRoutes(sub)
}

和user.handler.go文件，其中注册了“/user”子路径：

func RegisterRoutes(sub *mux.Router) {
    userRoutes := sub.StrictSlash(true).Path("/users").Subrouter()

    userRoutes.Methods("POST").HandlerFunc(getUsers)
    userRoutes.Methods("GET").HandlerFunc(getUsers)
}

func getUsers(w http.ResponseWriter, r *http.Request) {
    user := User{Name: "test", Password: "test"}

    fmt.Printf("%+v\n", r.Method)

    json.NewEncoder(w).Encode(user)
}

我正在测试上面设置的路径，并想出了一个奇怪的行为：

Test - GET - localhost:3000/api/v1/users  => Prints GET in console. (as expected)
Test - GET - localhost:3000/api/v1/users/  => Prints GET in console. (as expected)
Test - POST - localhost:3000/api/v1/users  => Prints POST in console. (as expected)
Test - POST - localhost:3000/api/v1/users/  => Prints GET in console. (And here is the strange behavior)

当我将 POST 发送到端点 (localhost:3000/api/users/) 并在 url 末尾添加斜杠时，它会触发 GET 而不是POST。

有人在使用 Gorilla Mux 时遇到过这种行为吗？

Answer 1

具体问题是mux issue 79, which is still pending (even if closed), also seen in mux issue 254

这似乎也与 mux issue 145 有关：StrictSlash 令人困惑

This

"When true, if the route path is "/path/", accessing "/path" will redirect to the former and vice versa. In other words, your application will always see the path as specified in the route."

和

"When false, if the route path is "/path", accessing "/path/" will not match this route and vice versa."

应该倒置，因为 strict==true 应该表示不允许尾部斜杠。
它的名称和文档令人困惑。
