c# - Azure存储错误: "An attempt was made to access a socket in a way forbidden by its access permissions."

标签 c# .net azure azure-storage azure-table-storage

问题:

我发现此错误存在一些问题，但这并不能解决我的问题。

我有一个托管在 Azure Web 应用程序(开发/测试 F1 层)中的 Web API，该应用程序将文件上传到 Azure 存储 blob 容器并保存到 Azure 存储表，但是当我这样做时，出现以下错误: “尝试以访问权限禁止的方式访问套接字。”。如果有人可以提供帮助或知道我可以在哪里查看，我将不胜感激。谢谢。

我已经尝试过:

我使用了 Application Insights 并附加了 VS 2019 中的调试器，完整的堆栈跟踪位于底部。

连接字符串(注意“...”以替换完整的 AccountName 和 AccountKey): "StorageConnectionString": "DefaultEndpointsProtocol=https;AccountName=s...001;AccountKey=TJi...nDkw==;EndpointSuffix=core.windows.net"

在 Azure Web 应用程序端，我完成了以下操作:

我已允许所有 CORS

enter image description here

我不使用任何 VNet

我没有任何访问限制

我使用的连接字符串取自 Azure 存储上设置下的访问键

在 Azure 存储方面，我完成了以下操作:

帐户类型:StorageV2(通用 v2)

我已允许所有 CORS

enter image description here

我不使用任何 VNet

允许访问设置为“所有网络”

用于上传文件的代码

BlobContainerClient container = new BlobContainerClient(_AppSettings.StorageConnectionString, 
$"patient-notes-{patientid}");
container.CreateIfNotExists(PublicAccessType.Blob);
var blockBlob = container.GetBlobClient(fileName);
blockBlob.Upload(stream);
return blockBlob.Uri;

代码到表存储:

private readonly AppSettings _AppSettings;
        private readonly CloudStorageAccount _storageAccount;
        private readonly CloudTableClient _tableClient;
        private readonly TelemetryClient _telemetry;

        public ErrorLogTableStorage(IOptions<AppSettings> appSettings, TelemetryClient telemetry)
        {
            _telemetry = telemetry;
            _AppSettings = appSettings?.Value;
            _storageAccount = CloudStorageAccount.Parse(_AppSettings.AzureTableStorageConnectionString);
            _tableClient = _storageAccount.CreateCloudTableClient();
            CloudTable table = _tableClient.GetTableReference(AzureStorageTable.ErrorLog.ToString());
            table.CreateIfNotExistsAsync();
        }

        public async Task CreateErrorLog(ErrorLogEntity errorLog)
        {
            try
            {
                CloudTable table = _tableClient.GetTableReference(AzureStorageTable.ErrorLog.ToString());
                TableOperation insertOperation = TableOperation.InsertOrMerge(errorLog);
                await table.ExecuteAsync(insertOperation);
            }
            catch (Exception ex)
            {
                _telemetry.TrackException(ex);
            }

        }

最佳答案

好的，我让它工作了，我必须将 AppSettings: 添加到应用程序设置中。

从此应用程序设置进行更改

到此

但是为什么我需要添加AppSettings:？

正确的做法是什么？
