我已经开发了一个简单的Azure函数，该函数应该连接到MySQL数据库，从那里获取一些记录并将其作为电子邮件附件发送。这些都在本地工作。当我部署代码时，它不起作用并产生以下错误

编辑--------这是代码：
MySqlConnection con = new MySqlConnection(strConnString);
MySqlCommand cmd = new MySqlCommand();
MySqlDataAdapter adp = new MySqlDataAdapter();
DataTable retVal = new DataTable();
DateTime dateValue = DateTime.Parse(dateTime);
string formatForMySql = dateValue.ToString("yyyy-MM-dd");
pinExclude.Add(401);
switch (ClientID)
{
case 1:
query = string.Format("SELECT * FROM tableWHERE DATE(TIMESTAMP)=DATE('{0}') AND pin={1}", formatForMySql, pin);
break;
case 2:
query = string.Format("SELECT * FROM utterances WHERE DATE(TIMESTAMP)=DATE('{0}') AND pin NOT IN('{1}')", formatForMySql, string.Join(",", pinExclude));
break;
}
cmd.Connection = con;
cmd.CommandText = query;
adp.SelectCommand = cmd;
if (con.State == ConnectionState.Closed)
{
con.Open();
adp.Fill(retVal);
con.Close();
}
return retVal;
检索连接字符串如下：
var config = new ConfigurationBuilder()
.SetBasePath(context.FunctionAppDirectory)
.AddJsonFile("local.settings.json", optional: true, reloadOnChange: true)
.AddEnvironmentVariables()
.Build();
string connectionString = config.GetConnectionString("Op-1");
if (string.IsNullOrEmpty(connectionString)) {
connectionString = Environment.GetEnvironmentVariable("Op-1", EnvironmentVariableTarget.Process);
}
任何想法可能出什么问题吗？
我们将不胜感激任何帮助。
