GRPC的ACME证书

Question

Is it possible to fit a m.GetCertificate into a GRPC client / server?

   m := &autocert.Manager{
        Cache:      autocert.DirCache("tls"),
        Prompt:     autocert.AcceptTOS,
        HostPolicy: autocert.HostWhitelist("example.com"),
    }
    go http.ListenAndServe(":http", m.HTTPHandler(nil))
    cert, err := m.GetCertificate(...)
    if err != nil {
        t.Fatalf("Failed to generate certificates %s", err)
    }
    creds := credentials.NewServerTLSFromCert(cert)
    srv := grpc.NewServer(grpc.Creds(creds))
    reflection.Register(srv)

Use NewTLS instead of NewServerTLSFromCert.
