Qt如何使用SSL发送简单的HTTPS后发布？
该程序应该使用QNetworkAccessManager通过HTTPS发送帖子。
以下是我的代码的一个简单示例。

QUrlQuery params;
QByteArray dane;
params.addQueryItem("mWyslijpost", ui->lineEdit->text());
dane.append(params.toString());


QUrl url("https://81.2.244.83/Testpostssl/infotest.php");


QNetworkRequest request(url);
request.setHeader(QNetworkRequest::ContentTypeHeader,"application/x-www-form-urlencoded");
QNetworkReply *reply = manager->post(request, dane);



QFile certFile(":/crt/cert.crt");
Q_ASSERT(certFile.open(QIODevice::ReadOnly));

QSslCertificate cert(&certFile, QSsl::Pem);

QSslSocket * sslSocket = new QSslSocket(this);
sslSocket->addCaCertificate(cert);

sslSocket->connectToHostEncrypted(SERVER,  443);

if (!sslSocket->waitForEncrypted())
{
    qDebug() << "Info " << sslSocket->errorString();
    return false;
}

QSslConfiguration config = sslSocket->sslConfiguration();
config.setProtocol(QSsl::TlsV1_2);

sslSocket->setSslConfiguration(config);
reply->setSslConfiguration(config);


// wait
QEventLoop elCzekaj;
connect(reply, SIGNAL(finished()), &elCzekaj, SLOT(quit()));
elCzekaj.exec();


if(reply->error() == QNetworkReply::NoError)
{
    qDebug() << reply->readAll();
 }
else
{
    qDebug() << "Error...";
    qDebug() << reply->errorString();
}

如何从服务器下载证书？如何配置QSsl？

Answer 1

要从同行那里获得证书，请尝试以下方法：

QSslSocket *socket = new QSslSocket();

QObject::connect(socket,
                 &QSslSocket::encrypted,
                 [=](){qDebug() << socket->peerCertificate() << " cert";}
);

socket->connectToHostEncrypted("stackoverflow.com", 443);

关于问题：“如何配置QSsl”，这取决于您想要做什么。如果您只是想通过TLS从Web服务器获取内容，只需使用QNetworkAccessManager即可。那里有默认值。
