gorilla/mux is

A powerful HTTP router and URL matcher for building Go web servers

Integrations

1. Enable path directive by using mux.Vars method

Run Demo

package main

import (
    "fmt"
    "net/http"
    "net/http/httptest"

    "github.com/ggicci/httpin"
    "github.com/gorilla/mux"
    "github.com/justinas/alice"
)

type ListUserReposInput struct {
    Username   string `in:"path=username"`
    Visibility string `in:"query=visibility"`
    Fork       bool   `in:"query=fork"`
}

func ListUserRepos(rw http.ResponseWriter, r *http.Request) {
    // Retrieve you data in one line of code!
    input := r.Context().Value(httpin.Input).(*ListUserReposInput)

    fmt.Printf("input: %#v\n", input)
}

func init() {
    // Register a directive named "path" to retrieve values from `mux.Vars`,
    // i.e. decode path variables.
    httpin.UseGorillaMux("path", mux.Vars)
}

func main() {
    router := mux.NewRouter()

    // Bind input struct with handler.
    router.Handle("/users/{username}/repos", alice.New(
        httpin.NewInput(ListUserReposInput{}),
    ).ThenFunc(ListUserRepos)).Methods("GET")

    r, _ := http.NewRequest("GET", "/users/ggicci/repos?visibility=public&fork=1", nil)

    rw := httptest.NewRecorder()
    router.ServeHTTP(rw, r)
}
