class Network {
  static let shared = Network()
  
    private(set) lazy var apollo: ApolloClient = {
        let client = URLSessionClient()
        let cache = InMemoryNormalizedCache()
        let store = ApolloStore(cache: cache)
        let provider = NetworkInterceptorProvider(client: client, store: store)
        let url = URL(string: ENDPOINT_URL)!
        let transport = RequestChainNetworkTransport(interceptorProvider: provider,
                                                     endpointURL: url)
        return ApolloClient(networkTransport: transport)
    }()
}

class NetworkInterceptorProvider: LegacyInterceptorProvider {
    override func interceptors<Operation: GraphQLOperation>(for operation: Operation) -> [ApolloInterceptor] {
        var interceptors = super.interceptors(for: operation)
        interceptors.insert(CustomInterceptor(), at: 0)
        return interceptors
    }
}

class CustomInterceptor: ApolloInterceptor {
    
    func interceptAsync<Operation: GraphQLOperation>(
        chain: RequestChain,
        request: HTTPRequest<Operation>,
        response: HTTPResponse<Operation>?,
        completion: @escaping (Swift.Result<GraphQLResult<Operation.Data>, Error>) -> Void) {
        request.addHeader(name: "Authorization", value: TOKEN_VALUE)
        
        print("request :\(request)")
        print("response :\(String(describing: response))")

        chain.proceedAsync(request: request,
                           response: response,
                           completion: completion)
    }
}
