我有以下代码将文件上传到我的 Azure 存储:
读取文件流如下:
FileStream fileStream = File.OpenRead(filePath);
并传递给函数=>
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,例如此示例 pdf => http://www.africau.edu/images/default/sample.pdf效果很好。但由于某种原因,如果我尝试上传 pdf 文件,如本页 =>
https://learn.microsoft.com/en-us/dotnet/core/
Dot.NET Core Documentation 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.
我认为这与文件大小无关,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。
我在这里遗漏了一些具体的东西吗?我还从https://learn.microsoft.com/en-us/azure/sql-database/下载了.pdf并从行 await blobClient.UploadAsync()
注意:作为引用,我发现了这个开放的 GitHub 问题,但尚未解决。 https://github.com/Azure/azure-sdk-for-net/issues/9212
最佳答案
我也被这个问题困扰了。解决方法很简单,只需将你的流位置设置为0即可。
stream.Position = 0;
一切就绪,就可以工作了。
关于c# - 执行 BlobClient.UploadAsync 时出现 HttpRequestException,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/59692408/
