graphql-client: Subscribe with Authentication is not working for me

var options = new GraphQLHttpClientOptions
{
     EndPoint = new Uri(APIUrl)
};

var httpClient = new HttpClient();
httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);

var graphQLHttpClient = new GraphQLHttpClient(options, httpClient, new GraphQL.Client.Serializer.Newtonsoft.NewtonsoftJsonSerializer());

This is my client.

Now I try to subscribe:

IObservable<GraphQLResponse<object>> subscriptionStream = graphQLHttpClient.CreateSubscriptionStream<object>(request);

IDisposable subscription = subscriptionStream.Subscribe(response =>
{
    var value = response.Data;
    if (response.Data != null)
    {
        var serializeResponse = JsonConvert.SerializeObject(response);
        Console.WriteLine(serializeResponse);
    }
});

But I never receive a response.

Currently you’ll have to reimplement one of the serializers (because that uses a private implementation of GraphQLRequest in order to correctly set JSON property names).

Edit: In v2.1.2 you can just Add() it, since GraphQLRequest is now based on Dictionary<string, object>…

Yes, that happens because this client does not send any context field.

What server library are u using? I suspect its apollo-server?

Currently there is no fixed specification on how to do authentication over websockets, and Apollo has from a quick glance decided to go for the “authenticate the websocket once on establishing the connection”.

I myself prefer the approach to add the authentication token to each query/mutation/subscription payload so you can check this on each request and be able to change it without destroying and reestablishing the websocket connection (since im using the websocket for queries/mutations too). How this can be done with graphql-dotnet was descibed in an earlier answer.

As I already said the implementation has to match that of the server. Feel free to locate and share the specification your server is using or even do a PR implementing it.
