我在获取响应请求取消并引发异常之前发送请求时，在asp.net核心中使用Masstransit Requst响应

Question

I am using Masstransit Request-Response in Asp.NetCore When I send Request before I get Response, Request is getting Cancelled and throwing this Exception

System.Threading.Tasks.TaskCanceledException: A task was canceled.

I have downloaded masstransit codes and debugging my project with it. I understand ClientRequestHandle dispose and cancel requests before my response is received.

I checked Consumer side and it works successfully and sends Response as expected.

Answer 1

When using the RequestHandle<T> , you need to maintain a reference to the handle until the request is completed and the response is received (or a timeout or fault occurs).

You can simplify this by using a single line method, of:

var response = await requestClient.GetResponse<T>(request);

If you need to add things to the request, such as headers, etc. then you need to keep the handle around until it's completed.

using(var handle = requestClient.Create(request))
{
    var response = await handle.GetResponse<T>();
}
