尝试将 Gqlgen 与 julienschmidt/httprouter 一起使用时找不到 404 页面

Question

下面是我的代码运行问题是我找不到 404 页面而不是 graphql playground 页面是否可以使用带有 gqlgen 的 httprouter 还是我需要返回到 chi 或 mux 我也无法使用中间件，因为 r 没有 Use 方法

package main

import (
    "gographql-server/graph"
    "gographql-server/graph/generated"
    "log"
    "net/http"
    "os"

    "github.com/99designs/gqlgen/graphql/handler"
    "github.com/99designs/gqlgen/graphql/playground"
    "github.com/julienschmidt/httprouter"
)

const defaultPort = "8080"

func PlaygroundHandler() httprouter.Handle {
    h := playground.Handler("GraphQL", "/query")

    return func(w http.ResponseWriter, req *http.Request, ps httprouter.Params) {
        h.ServeHTTP(w, req)
    }
}

func GraphqlHandler() httprouter.Handle {
    h := handler.NewDefaultServer(generated.NewExecutableSchema(generated.Config{Resolvers: &graph.Resolver{}}))

    return func(w http.ResponseWriter, req *http.Request, ps httprouter.Params) {
        h.ServeHTTP(w, req)
    }
}

func main() {
    port := os.Getenv("PORT")
    if port == "" {
        port = defaultPort
    }
    r := httprouter.New()
    r.POST("/query", GraphqlHandler())
    r.GET("/", PlaygroundHandler())
    // r.Use(middleware.RequestID)
    // r.Use(middleware.Logger)
    // r.Use(middleware.Recoverer)
    // r.Use(middlewares.AuthMiddleware())
    log.Printf("connect to http://localhost:%s/ for GraphQL playground", port)
    log.Fatal(http.ListenAndServe(":"+port, nil))
}

Answer 1

如果您在这一行中将 nil 传递给 http.ListenAndServe()：

log.Fatal(http.ListenAndServe(":"+port, nil))

这意味着 DefaultServeMux of the net/http package is used. But you you don't register any handlers in the default mux, you create your own router using httprouter.New()，您可以在其中注册处理程序。

所以你必须把这个路由器传给ListenAndServe():

log.Fatal(http.ListenAndServe(":"+port, r))
