Custom HttpClient for GraphQLClient

[OneCyrus]

It would be very helpful to supply my own instance of HttpClient to the GraphQLClient constructor. Currently it allows to supply a HttpMessageHandler. But this way I can't specify authorization tokens.

Or is there another way to acomplish this?

Well, if you specify better what is your use case i can give help.

If you need to add a Header you can use something like this:

var graphClient = new GraphQLClient("https://api.github.com/graphql");
graphClient.DefaultRequestHeaders.Add("Authorization", $"bearer {gitHubAccessToken}");
//var test = await graphClient.GetIntrospectionQueryAsync();
var request = new GraphQLRequest
{
    Query = @"query { viewer { login } }"
};
var test = await graphClient.PostAsync(request);

IDK if this solves your issue or you have a better idea of how to implement your case

thanks that did the trick!

my use case is integration testing a graphql endpoint which is started as a .net core TestServer. it was a bit tricky because it's not an endpoint which is accessible as any other real endpoint.

I can't add DefaultRequestHeaders with IGraphQLClient, how can this be done, please?

@Version of GraphQL.Client is 3.1.3

Try:

GraphQLHttpClient client = new GraphQLHttpClient("https://example.com/graphql", new NewtonsoftJsonSerializer());
client.HttpClient.DefaultRequestHeaders.Add("Authorization", accessToken);

I had to use the HttpClient Library to get around this party issue as IGraphQLClient didn't seem to have a direct support for adding Default HTTP Headers, you can try this example on this GitHub gist :

You can just treat it like a normal HTTP request. The GraphQL server endpoint figures the rest out from your structure.
