如何在不等待 ASP.NET API 中的响应的情况下处理多个 3rd 方 API

Question

Let's assume I have add order API & I need to call 3 APIs if the order is saved successfully. I want to return the response as soon as the order processing is finished without waiting for the 3 APIs to finish.

For example:

var result = ProcessOrder(parameters);
if (result.IsSuccess)
{
   await SendSMSAsync(smsDetails);   //All 3 APIs includes calling the API, saving status to database & log
   await SendEmailAsync(emailDetails);
   await ThirdPartyAsync(moreDetails);
}
return result;   //I want to return this without waiting for the above 3 APIs to finish

Also, I would like to call again any failed API automatically. What's the best approach to achieve this?

Answer 1

Instead of await, create a task and call Task.Run. This will run without waiting for the task to return.

Answer 2

I achieved this by using .ConfigureAwait(false) . For example:

if (result.IsSuccess)
{
   SendSMSAsync(smsDetails).ConfigureAwait(false);
   SendEmailAsync(emailDetails).ConfigureAwait(false);
   ThirdPartyAsync(moreDetails).ConfigureAwait(false);
}
