Question

所以我在QTCreator中处理一个非常基本的服务器/客户端事情。当客户端尝试连接时，我应该让服务器将证书发送到客户端。我在服务器中有以下代码：

void Dialog::createSocket()

{    
tcpSocket = (QSslSocket*)tcpServer->nextPendingConnection();

QByteArray key;
QByteArray cert;
QByteArray block;

QFile fileKey("C:/Users/siu850967358.AD.002/Desktop/ECE424_Lab2/server.key");
if(fileKey.open(QIODevice ::ReadOnly))
{
      key = fileKey.readAll();
      fileKey.close();
}
else
{
      qDebug() << fileKey.errorString();
}

QFile fileCert("C:/Users/siu850967358.AD.002/Desktop/ECE424_Lab2/server.crt");
if(fileCert.open(QIODevice ::ReadOnly))
{
      cert = fileCert.readAll();
      fileCert.close();
}
else
{
      qDebug() << fileCert.errorString();
}

qDebug() << key + "\n" + cert;

QString mykey(cert);
QSslKey ssl_Key(key, QSsl::Rsa);
QSslKey* sslKey = &ssl_Key;
QSslCertificate ssl_Cert(cert);
QSslCertificate* sslCert = &ssl_Cert;


//CRASH HAPPENS HERE

qDebug() << "ok";
tcpSocket->setPrivateKey(ssl_Key);
qDebug() << "ok2";
tcpSocket->setLocalCertificate(ssl_Cert);
qDebug() << "Key and certificate set";


//CRASH HAPPENS HERE


QDataStream out(&block, QIODevice::WriteOnly);
out.setVersion(QDataStream::Qt_4_0);
out << (quint16)0;
out << mykey;
out.device()->seek(0);
out << (quint16)(block.size() - sizeof(quint16));
qDebug() << "write the certificate to the socket so that client may get the pubkey";
tcpSocket->write(block);


//connect(tcpSocket, SIGNAL(encrypted()), this, SLOT(readSocket()));
connect(tcpSocket, SIGNAL(readyRead()), this, SLOT(readSocket()));
tcpSocket->startServerEncryption();


}

tcpSocket-＆GT; setPrivateKey（ssl_Key）;导致崩溃。 tcpSocket-＆GT; setPrivateKey（键）;不会导致崩溃，虽然我认为这是不正确的.... 同样处理tcpSocket-＆gt; setLocalCertificate（）;

任何想法？顺便说一下这个位置tcpSocket-＆gt; flush（）也会崩溃... 谢谢你提前

你不能简单地将QTcpSocket转换为QSslSocket并期望事情能够发挥作用。有关如何使用Qt编写SSL服务器的示例，请参阅https://gitorious.org/qt-examples/qt-examples/source/7fdab8bcca3b1083cd07670131c75874300ad2d3:sslserver。

尝试访问QSslSocket函数时服务器崩溃
