尝试如下操作：
config.MessageHandlers.Add(new CancelledTaskBugWorkaroundMessageHandler());

class CancelledTaskBugWorkaroundMessageHandler : DelegatingHandler
{
protected override async Task SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
{
HttpResponseMessage response = await base.SendAsync(request, cancellationToken);

    // Try to suppress response content when the cancellation token has fired; ASP.NET will log to the Application event log if there's content in this case.

    if (cancellationToken.IsCancellationRequested)

    {

        return new HttpResponseMessage(HttpStatusCode.InternalServerError);

    }

    return response;

}

}
