Dependency Injection: one interface multiple times

Dependency Injection: one interface multiple times

Vop Royal 1

hello all,

using .net core .31 i have a situation that in Dependency injection i have to use one Interface with different url's. below is my existing code.

public static IServiceCollection ResolveDependencies(this IServiceCollection services, IConfiguration configuration)
{
var graphQlHttpClient = new GraphQLHttpClient(
configuration["MyGraphqlLink"],
new NewtonsoftJsonSerializer());

            services.AddSingleton<IGraphQLClient>(s => graphQlHttpClient);
    }

above is existing code and its working fine. but, i have a scenario that i have to use 2 or 3 graphql link also in the same section so, may i know how do i use GraphQLHttpClient
with 2 or 3 different URL's?

experts kindly support.

I'm not sure what GraphQL client you are using but a typical configuration is one HTTP client for each API service you're invoking. The reference documentation should explain how to configure the client. I assume you have one service???

Hi @Vop Royal ,

You can try to create NET Core HTTP client factory for each graphql link, refer this article: Consuming a GraphQL api using .NET Core and GraphQL.Client NuGet package.
