まず、サーバーはクライアントに証明書を要求しません。それは別の方法です。クライアントは、常にそうとは限らないが、サーバーに証明書を要求することはできない。あなたの質問の文言から、それはあなたが証明書を使用する必要はないかもしれないように聞こえる。特にそうでない場合は、linkを参照してください。通常、サーバーはクライアントを認証する必要がありますが、これは通常、セキュリティで保護された接続が確立された後にサーバーに戻されるユーザー名/パスワードメッセージによって行われます。サーバーとクライアントの両方でそれを処理するコードを書く責任があります。ここで
は、私がSSL接続を介してサーバーに接続するために使用するいくつかのコードです：
void SSLSocket::Connect(SSLSocket* psSLS, const string& serverPath, string& port)
{
// Connects to the server.
// serverPath - specifies the path to the server. Can be either an ip address or url.
// port - port server is listening on.
//
try
{
boost::shared_ptr<boost::asio::io_service> IOServ(new boost::asio::io_service);
IOService = IOServ; // Defined the same way in the class
Locking CodeLock(SocketLock); // Single thread the code.
// If the user has tried to connect before, then make sure everything is clean before trying to do so again.
if (pSocket)
{
delete pSocket;
pSocket = 0;
}
// Create the resolver and query objects to resolve the host name in serverPath to an ip address.
boost::asio::ip::tcp::resolver resolver(*IOService);
boost::asio::ip::tcp::resolver::query query(serverPath, port);
boost::asio::ip::tcp::resolver::iterator EndpointIterator = resolver.resolve(query);
// Set up an SSL context.
boost::asio::ssl::context ctx(*IOService, boost::asio::ssl::context::tlsv1_client);
// Specify to not verify the server certificiate right now.
ctx.set_verify_mode(boost::asio::ssl::context::verify_none);
// Init the socket object used to initially communicate with the server.
pSocket = new boost::asio::ssl::stream<boost::asio::ip::tcp::socket>(*IOService, ctx);
//
// The thread we are on now, is most likely the user interface thread. Create a thread to handle all incoming and outgoing socket work messages.
