使用 go-chi 路由器时无法连接到 graphql playground

Question

我正在使用 gqlgen 创建一个 go graphql 服务器。

在教程中，localhost:8080 的默认设置工作正常。

server.go

...
func main() {
    srv := handler.NewDefaultServer(generated.NewExecutableSchema(generated.Config{Resolvers: &graph.Resolver{}}))

    http.Handle("/", playground.Handler("GraphQL playground", "/query"))
    http.Handle("/query", srv)

    log.Fatal(http.ListenAndServe(":8080", nil))
}
...

但是，如果我切换到 Chi 包路由器，我会收到 400 错误：

server.go

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

    srv := handler.New(generated.NewExecutableSchema(generated.Config{Resolvers: &graph.Resolver{}}))

    router.Handle("/", playground.Handler("GraphQL Playground", "/query"))
    router.Handle("/query", srv)

    err := http.ListenAndServe(":8080", router)
    if err != nil {
        panic(err)
    }
}
...

原来你必须使用 NewDefaultServer 而不是 New:

srv := handler.NewDefaultServer(generated.NewExecutableSchema(generated.Config{Resolvers: &graph.Resolver{}}))
