Oracle 自治连接的 ODP.Net Core Appsettings.json 配置

Question

我按照 oracle 的代码示例使用标准连接配置到 oracle db 的连接：

{
  "ConnectionStrings": {
    "DefaultConnection": "User Id=<USER ID>;Password=<PASSWORD>;Data Source=<DATA SOURCE>;"
  }
}

我正在尝试控制台示例来测试与 oracle 自治数据库的连接：

using System;
using Oracle.ManagedDataAccess.Client;

namespace ODP.NET_Core_Autonomous
{
    class Program
    {
        static void Main(string[] args)
        {
            //Demo: ODP.NET Core application that connects to Oracle Autonomous DB

            //Enter user id and password, such as ADMIN user    
            string conString = "User Id=admin;Password=XXXXXXX;" +

            //Enter net service name for data source value
            "Data Source=autonomous;";

            using (OracleConnection con = new OracleConnection(conString))
            {
                using (OracleCommand cmd = con.CreateCommand())
                {
                    try
                    {
                        //Connect descriptor and net service name entry
                        //Enter the database machine port, hostname/IP, service name, and distinguished name
                        OracleConfiguration.OracleDataSources.Add("autonomous", "(description= (retry_count=20)(retry_delay=3)(address=(protocol=tcps)(port=1522)(host=adb.ap-mumbai-1.oraclecloud.com))(connect_data=(service_name=XXXXXXX_webapi_high.atp.oraclecloud.com))(security=(ssl_server_cert_dn=CN=adb.ap-mumbai-1.oraclecloud.com,OU=Oracle ADB INDIA,O=Oracle Corporation,L=Redwood City,ST=California,C=US)))");

                        //Enter directory where wallet is stored locally
                        OracleConfiguration.WalletLocation = @"/home/opc/wallet/Wallet_webapi.zip";

                        con.Open();

                        Console.WriteLine("Successfully connected to Oracle Autonomous Database");

                        //Retrieve database version info
                        cmd.CommandText = "SELECT BANNER FROM V$VERSION";
                        OracleDataReader reader = cmd.ExecuteReader();
                        reader.Read();
                        Console.WriteLine("Connected to " + reader.GetString(0));
                    }
                    catch (Exception ex)
                    {
                        Console.WriteLine(ex.Message);
                    }

                    Console.ReadLine();
                }
            }
        }
    }
}

结果： [opc@myhost oratest]$ sudo dotnet run 连接请求超时

现在我想测试与 Oracle Cloud（自治数据库）的连接，如何通过 appsettings.json 配置钱包和连接设置？
