在 Golang 中使用 Chi 路由器将参数传递到 URL 时出现 404 错误

Question

我尝试将 url 参数传递到端点，但在尝试运行测试或通过 Postman 发送请求时出现 404 page not find 错误。

我的路线方法：

func NewListRoutes(
    r *chi.Mux,
    log *slog.Logger,
    jwt *jwtoken.TokenService,
    usecase port.ListUsecase,
) {
    c := &listController{
        logger:  log,
        jwt:     jwt,
        usecase: usecase,
    }

    // Protected routes
    r.Group(func(r chi.Router) {
        r.Use(jwtoken.Verifier(jwt))
        r.Use(jwtoken.Authenticator())

        r.Route("/user/lists", func(r chi.Router) {
            r.Get("/", c.GetListsByUserID())
            r.Post("/", c.CreateList())

            r.Route("/{list_id}", func(r chi.Router) {
                r.Get("/", c.GetListByID())
                r.Put("/", c.UpdateList())
                r.Delete("/", c.DeleteList())
            })
        })
    })
}

我的测试：

func TestGetListByID_HappyPath(t *testing.T) {
    u := url.URL{
        Scheme: "http",
        Host:   host,
    }
    e := httpexpect.Default(t, u.String())

    // Register user
    r := e.POST("/register").
        WithJSON(model.UserRequestData{
            Email:    gofakeit.Email(),
            Password: randomFakePassword(),
        }).
        Expect().
        Status(http.StatusCreated).
        JSON().Object()

    accessToken := r.Value(jwtoken.AccessTokenKey).String().Raw()
    t.Log(accessToken)

    // Create list
    c := e.POST("/user/lists/").
        WithHeader("Authorization", "Bearer "+accessToken).
        WithJSON(model.ListRequestData{
            Title: gofakeit.Word(),
        }).
        Expect().
        Status(http.StatusCreated).
        JSON().Object()

    listID := c.Value("data").Object().Value("id").String().Raw()

    t.Log(listID)

    // Get list by ID
    getListResp := e.GET("/user/lists/{list_id}").
        WithPath("list_id", listID).
        WithHeader("Authorization", "Bearer "+accessToken).
        Expect().
        Status(http.StatusOK).
        JSON().Object().NotEmpty()

    t.Log(getListResp.Raw())
}

在日志中我看到其他请求正常工作（注册用户、创建列表），但使用 url 参数时我遇到了这个问题。

我做错了什么？

UPD。 如果我使用查询参数，一切正常，但如果我使用 url 参数，就会出现问题

Answer 1

找到了解决方案，但还没有完全弄清楚为什么会这样。在我的项目中，我也有这条路线：

r.Group(func(r chi.Router) {
        r.Use(jwtoken.Verifier(jwt))
        r.Use(jwtoken.Authenticator())

        r.Post("/logout", c.Logout())

        r.Route("/user", func(r chi.Router) {
            r.Get("/", c.GetUser())
            r.Put("/", c.UpdateUser())
            r.Delete("/", c.DeleteUser())
        })
    })

“/user”和“/user/lists/”的路由和处理程序之间存在冲突。我从列表的路由中删除了“用户”一词，现在一切正常：

r.Group(func(r chi.Router) {
        r.Use(jwtoken.Verifier(jwt))
        r.Use(jwtoken.Authenticator())

        r.Route("/lists", func(r chi.Router) {
            r.Get("/", c.GetListsByUserID())
            r.Post("/", c.CreateList())

            r.Route("/{list_id}", func(r chi.Router) {
                r.Get("/", c.GetListByID())
                r.Put("/", c.UpdateList())
                r.Delete("/", c.DeleteList())
            })
        })
    })
