在执行BlobClient.UploadAsync时出现HttpRequestException。

Question

我有以下代码上传文件到我的Azure存储。

读取文件流像下面。

   FileStream fileStream = File.OpenRead(filePath);

并传递给函数=&gt。

 public async Task<Response<BlobContentInfo>> UploadBlob(string containerName, string blobName, Stream stream, string contentType,
            IDictionary<string, string> metadata = null)
        {
            IDictionary<string, string> metadataEncoded = new Dictionary<string, string>();
            if (metadata != null)
            {
                foreach (KeyValuePair<string, string> keyValuePair in metadata)
                {
                    string encodedValue = TextUtilities.Base64Encode(keyValuePair.Value);
                    metadataEncoded.Add(keyValuePair.Key, encodedValue);
                }
            }
            await using (stream)
            {
                BlobClient blobClient = GetBlobClient(containerName, blobName);
                BlobHttpHeaders httpHeaders = new BlobHttpHeaders { ContentType = contentType };
                BlobRequestConditions conditions = new BlobRequestConditions();
                Response<BlobContentInfo> uploadAsync = await blobClient.UploadAsync(stream, httpHeaders, metadataEncoded, conditions);
                stream.Close();
                return uploadAsync;
            }
        }

如果我尝试上传任意文件，比如这个样本pdf => http:/www.africau.eduimagesdefaultsample.pdf 它工作正常。但由于某些原因，如果我尝试上传pdf文件，如在这个页面=> https:/docs.microsoft.comen-usdotnetcore。 Dot.NET核心文档PDF

我收到以下异常。

Inner Exception 1:
HttpRequestException: Error while copying content to a stream.

Inner Exception 2:
IOException: Unable to read data from the transport connection: The I/O operation has been aborted because of either a thread exit or an application request..

Inner Exception 3:
SocketException: The I/O operation has been aborted because of either a thread exit or an application request.

我不认为这与文件大小有关，因为我还尝试了其他一些大尺寸的.pdf文件，它们被推送到Azure存储。

我是否遗漏了一些特定的东西？我还从 https:/docs.microsoft.comen-usazuresql-database。 并从该行收到同样的错误 await blobClient.UploadAsync()

注：作为参考，我找到了这个开放的GitHub问题，但还没有解决。https:/github.comAzureazure-sdk-for-netissues9212。

我也曾卡过这个问题。它的解决方法很简单，只要将你的流位置设置为0即可。

stream.Position = 0。

所有的设置，它将工作。
