404 page not found when trying to use Gqlgen with julienschmidt/httprouter
问题
以下是我运行的代码。问题是我得到了404页面未找到，而不是graphql playground页面。是否可以使用httprouter与gqlgen一起工作，还是我需要回到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))
}
希望对你有帮助！

Below is the code I run
the issue is that I get 404 page not found instead of the graphql playground page
Is it possible to work with httprouter with gqlgen or do I need to go back to chi or mux
I also was not able to use middlewares because r does not have Use method
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))
}

得分: 1
如果你在这一行中将nil传递给http.ListenAndServe()：
log.Fatal(http.ListenAndServe(":"+port, nil))
这意味着使用了net/http包中的DefaultServeMux。但是如果你没有在默认的mux中注册任何处理程序，而是使用httprouter.New()创建了自己的路由器，并在其中注册处理程序。
所以你必须将这个路由器传递给ListenAndServe()：
log.Fatal(http.ListenAndServe(":"+port, r))
英文:
If you pass nil to http.ListenAndServe() in this line:
log.Fatal(http.ListenAndServe(":"+port, nil))
That means the 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(), and you register handlers in that.
So you must pass this router to ListenAndServe():
log.Fatal(http.ListenAndServe(":"+port, r))
