NET的GraphQL-取消令牌

Question

有没有办法在graphql端点中传递取消令牌？

public class GetAccountQuery : ObjectGraphType
{ public GetAccountQuery(IRolver resolver)
        {
            FieldAsync<UserType>(
                "GetAccount",
                arguments: new QueryArguments(
                    new QueryArgument<NonNullGraphType<IdGraphType>> { Name = "userId" },
                resolve: async context => await resolver.ResolveAsync(context, pass in cancellation token ?? ));
        }
}

Answer 1

找到答案，将IHttpContextAccessor注入GetAccountQuery ctor中，然后像下面这样从httpcontext访问Cancellation令牌：

HttpContextAccessor.HttpContext.RequestAborted
