问使用Polly httpClient ConfigureAwait重试模式(True)

EN

 var appendFileResponse = await Policy
            .HandleResult<HttpResponseMessage>(message => !message.IsSuccessStatusCode)
            .WaitAndRetryAsync(3, retryAttempt => TimeSpan.FromSeconds(Math.Pow(2, retryAttempt)))
            .ExecuteAsync(async () => await httpClient.SendAsync(request).ConfigureAwait(true))
            .ConfigureAwait(true);

 if (appendFileResponse.StatusCode != System.Net.HttpStatusCode.Accepted)
 {
            throw new ApplicationException($"Failed to append file");
 }
