How to add custom headers in grpc-gateway

Adding custom header to grpc request

md1 := func(context.Context, *http.Request) metadata.MD {
  return metadata.New(map[string]string{
    "custom-header": "custom-value",
  })
}

mux := runtime.NewServeMux(runtime.WithMetadata(md1))

Serving GRPC gateway and docs on same endpoint

Serving GRPC gateway and docs(swagger) on same endpoint

So idea is pretty simple:

We'll create a new httpMux
We'll serve runtimeMux on (/)
We'll serve index.html (using fileserver) on (/docs/)
We'll not forget succeeding "/" on /docs/

In action:

Modify the example pt. 6 in this way:

Using TLS in grpc-gateway

In GRPC client

By default DialOption{grpc.WithInsecure()} is used in example. And as docs mention you just need to replace WithInsecure with transport creds.

//opts := []grpc.DialOption{grpc.WithInsecure()}
creds, _ := credentials.NewClientTLSFromFile("tls.crt", "")
opts := []grpc.DialOption{grpc.WithTransportCredentials(creds)}
