如何在 Azure 表存储的 StorageCredentials 上使用 SAS？

我使用 .NET API 在给定表上创建 SAS：

        var tablePolicy = new SharedAccessTablePolicy()
        {
            SharedAccessExpiryTime = DateTime.Now.Add(TimeSpan.FromHours(2)),
            Permissions = SharedAccessTablePermissions.Query
        };
        var permissions = new TablePermissions();

        permissions.SharedAccessPolicies.Add("myPolicy", tablePolicy);

        var credentials = new StorageCredentials(
            "#my account here#",
            "#my account secondary key here#");
        var tableClient = new CloudTableClient(
            new Uri("https://#my account here#.table.core.windows.net/"),
            credentials);
        var logTable = tableClient.GetTableReference("WADLogsTable");

        logTable.SetPermissions(permissions);

        var sas = logTable.GetSharedAccessSignature(tablePolicy, "myPolicy", null, null, null, null);

然后，我使用最后一个“sas”变量来创建凭据并执行查询：

        var credentials = new StorageCredentials(sas);
        var tableClient = new CloudTableClient(
            new Uri("#my account URI here#"),
            credentials);
        var logTable = tableClient.GetTableReference("WADLogsTable");
        var rows = logTable.ExecuteQuery(new TableQuery()).ToArray();

然后我收到 403（禁止）错误。

我做错了什么？

我相信您会收到此错误，因为您同时定义了两者SharedAccessTablePolicy and Policy Name创建 SAS 时。因此，如果您使用以下任一方法应该有效：

var sas = logTable.GetSharedAccessSignature(tablePolicy, null, null, null, null, null);

or

var sas = logTable.GetSharedAccessSignature(null, "myPolicy", null, null, null, null);
