从Unity到数据库的安全连接

using System.Data.SqlClient;

string connectionString = "Server=myServerAddress;Database=myDataBase;User Id=myUsername;Password=myPassword;Encrypt=True;TrustServerCertificate=False;";
SqlConnection connection = new SqlConnection(connectionString);
connection.Open();

// 假设已通过VPN建立安全通道
string vpnTunnelAddress = "vpn://myVpnServer";
string databaseConnectionString = "Server=myServerAddress;Database=myDataBase;User Id=myUsername;Password=myPassword;";

// 通过VPN隧道连接数据库
SqlConnection connection = new SqlConnection(vpnTunnelAddress + databaseConnectionString);
connection.Open();

using System.Net.Http;
using System.Threading.Tasks;

string apiUrl = "https://myApiGateway/api/data";
string accessToken = "myAccessToken";

HttpClient client = new HttpClient();
client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", accessToken);

HttpResponseMessage response = await client.GetAsync(apiUrl);
if (response.IsSuccessStatusCode)
{
    string data = await response.Content.ReadAsStringAsync();
    // 处理数据
}
