我有一个通过混合连接运行到本地服务器的 Azure 函数。一切都很好。将来我们将在多个位置拥有多个混合连接，并且它们可能具有相同的服务器名称和端口组合。
在执行 SQL 操作之前，有没有办法验证（或调试）正在使用的混合连接的服务总线命名空间或 UserMetadata 属性？
这是来自函数应用的 run.csx：
#r "System.Data"
using System.Net;
using System.Collections.Generic;
using System.Configuration;
using Newtonsoft.Json;
using System.Data.SqlClient;
using System.Text;
public static async Task<HttpResponseMessage> Run(HttpRequestMessage req, TraceWriter log)
{
log.Info("C# HTTP trigger function processed a request.");
string connectionString = "Server=MyServerName;Initial Catalog=BillingDB;";
string queryString = "select top 2 * from Billing";
List<Billing> bills = new List<Billing>();
SqlConnection conn = new SqlConnection(connectionString);
conn.Open();
/***************
Here is where I would like to be able to verify/validate
the namespace or UserMetadata of the hybrid connection so that I'm sure
we're connecting to the desired database. "Server" in the connection string
is not enough in our case.
******************/
SqlCommand DBCmd = new SqlCommand(queryString, conn);
SqlDataReader myDataReader;
myDataReader = DBCmd.ExecuteReader();
while (myDataReader.Read())
{
bills.Add(new Billing
{
Student_ID = Convert.ToInt32(myDataReader[0]),
Transaction_Number = Convert.ToInt32(myDataReader[1]),
Log = myDataReader[2].ToString(),
Amount_Owed = Convert.ToDecimal(myDataReader[3])
}
);
}
myDataReader.Close();
conn.Close();
var json = JsonConvert.SerializeObject(bills);
log.Info("json: " + json);
return req.CreateResponse(HttpStatusCode.OK,json);
}
public class Billing {
public int Student_ID { get; set; }
public int Transaction_Number { get; set; }
public string Log { get; set; }
public decimal Amount_Owed { get; set; }
}
