Question

我认为我的问题类似于C#: how to check if a MySqlConnection is using SSL or not?，但遗憾的是它并没有很好的答案，因为可能还不清楚。所以这是我的看法：

我创建了一个新连接：

var connection = new MySqlConnection("Data Source=example.com;Port=3306;Database=Foo;User Id=root;Password=foo;SSL Mode=Required");

如何验证它是否使用SSL，是否有类似connection.IsOverSSL的内容？

修改

我尝试使用SHOW SESSION STATUS LIKE 'Ssl_cipher'，但即使Ssl_cipher，这也会给我SSL Mode=Required：

我使用的代码是：

var connection = new MySqlConnection(ConfigurationManager.AppSettings["Test"]);
connection.Open();
var command = new MySqlCommand("SHOW SESSION STATUS LIKE \'Ssl_cipher\'", connection);
MySqlDataReader reader = command.ExecuteReader();
while (reader.Read())
{
    Console.WriteLine(reader.GetString(0));
}

根据https://dev.mysql.com/doc/refman/5.7/en/using-encrypted-connections.html，它应该给我Ssl_cipher | DHE-RSA-AES128-GCM-SHA256

Answer 1

您可以查看单词“SSL”的连接字符串。这将允许您知道在这种情况下您的IDbConnection是否正在使用ssl。有关可以与MySql一起使用的连接字符串的列表，请访问ConnectionStrings.com。如果这可以解决您的问题，请告诉我。

我会尝试查看连接字符串。这是一个证明这一点的解决方案。

var connStr = "Data Source=example.com;Port=3306;Database=Foo;User Id=root;Password=foo;SSL Mode=Required";
var sslElement = connStr.Split(';')
    .SingleOrDefault(s => s.StartsWith("SSL", StringComparison.InvariantCultureIgnoreCase));

var sslModeEnabled = (sslElement != null 
    && string.Equals(sslElement.Split('=')[1].Trim(), "None", StringComparison.InvariantCultureIgnoreCase) == false);


Console.WriteLine($"SSL Mode Enabled: {sslModeEnabled}");

原来我没有打印查询的第二列，现在可行了：

rails aborted!

(See full trace by running task with --trace)

它为var connection = new MySqlConnection(ConfigurationManager.AppSettings["Test"]); connection.Open(); var command = new MySqlCommand("SHOW SESSION STATUS LIKE \'Ssl_cipher\'", connection); MySqlDataReader reader = command.ExecuteReader(); while (reader.Read()) { Console.WriteLine($"{reader.GetString(0)}: {reader.GetString(1)}"); }打印Ssl_cipher: AES256-SHA，为SSL Mode=Required打印Ssl_cipher:。另一方面，即使SSL Mode=None完全丢失，我也会Ssl_cipher: AES256-SHA，所以默认情况下它可能会启用。
