c# - 为什么 Azure WebJob 无法连接到 Azure SQL，显示“"Storage account is of unsupported type ' Blob-Only/ZRS”。支持的类型是 'General Purpose' ？

Question

所以我有一个 Azure Web 应用程序，它是一个带有 Entity Framework 的 ASP.NET MVC 应用程序。它使用 Azure SQL 数据库。我需要定期(每天一次)调查金融市场利率数字并将其插入数据库。我为两个市场利率民意调查创建了两个 WebJobs(一个需要在开盘后运行，另一个需要在收市后运行)，并安排它们。

为了进行测试，我通过 Azure 门户手动触发它们，我在日志中收到以下错误:

我无法理解这一点。 SQL Azure 数据库是一种普通的数据库，一些表有 blob 列，但 MarketRates 表没有。尝试访问数据库的代码:

string connectionString = "Copy of the the Azure SQL connection string";
SqlConnection sqlConnection = new SqlConnection(connectionString);

string selectStatement = "SELECT MAX(Id) FROM BlaBla.dbo.MarketRates";
SqlCommand selectCmd = new SqlCommand(selectStatement, sqlConnection);
sqlConnection.Open();
var id = (int)selectCmd.ExecuteScalar();
sqlConnection.Close();

string insertStatement = "INSERT INTO BlaBla.dbo.MarketRates(Id, Type, Rate, Date) " +
    "VALUES(@Id, @Type, @Rate, @Date)";
SqlCommand insertCmd = new SqlCommand(insertStatement, sqlConnection);

var now = DateTime.Now;
insertCmd.Parameters.Add("@Id", SqlDbType.Int);
insertCmd.Parameters.Add("@Type", SqlDbType.VarChar, 64);
insertCmd.Parameters.Add("@Rate", SqlDbType.Float);
insertCmd.Parameters.Add("@Date", SqlDbType.DateTime);
insertCmd.Parameters["@Id"].Value = id + 1;
insertCmd.Parameters["@Type"].Value = rateType;
insertCmd.Parameters["@Rate"].Value = rate;
insertCmd.Parameters["@Date"].Value = now.Date;

sqlConnection.Open();
insertCmd.ExecuteNonQuery();
sqlConnection.Close();

Answer 1

"Storage account is of unsupported type 'Blob-Only/ZRS'. Supported types are 'General Purpose'?

看来您正在使用blob storage account使用 Azure 网络作业。请尝试将 AzureWebJobsStorageconnection 字符串更改为另一个通用用途 storage account连接。

另外，在您的 app.settings 开头，使用通用存储帐户的连接字符串填充 AzureWebJobsDashboard 和 AzureWebJobsStorage 连接字符串。网络作业。
