qt.network.ssl: QSslSocket: cannot resolve SSLv2_client_method

[hiren21]

I am trying to POST request to remote server. Here is my code:

void LoginWindow::on_login_pushButton_clicked()
{
    const QString url = ui->server_lineEdit->text ();
    const QString username = ui->username_lineEdit->text ();
    const QString password = ui->password_lineEdit->text ();
    QNetworkAccessManager mAccessManager;
    QNetworkRequest request(QUrl(url + "/api/auth/"));

    QUrlQuery urlQuery;
    urlQuery.addQueryItem ("username", username);
    urlQuery.addQueryItem ("password", password);

    QUrl params;
    params.setQuery (urlQuery);

    QNetworkReply* reply = mAccessManager.post (request, params.toEncoded ());

    connect (reply, &QNetworkReply::readyRead, [reply]() {
        qDebug()  << "Ready to read from reply";
    });
    connect (reply, &QNetworkReply::sslErrors, [this] (QList<QSslError> error) {
        qWarning () << "Ssl error: " << error;
    });

}

Everytime I clicked the login button nothing happens, except a message in application output tab.

qt.network.ssl: QSslSocket: cannot resolve SSLv2_client_method
qt.network.ssl: QSslSocket: cannot resolve SSLv2_server_method

I am using ubuntu 16.04 and Qt 5.9 . Here is a similar problem in the forum. I also installed libssl-0.98 , but still no luck.

Hi,

What exact version of OpenSSL are you using ?

What error message did you get in your application if any ?

[hiren21]

Here is the output of QSslSocket::sslLibraryBuildVersionString() OpenSSL 1.0.1e-fips 11 Feb 2013

One of the reasons of that kind of message is that the version loaded at runtime differs from the one used at building time.

So any idea how do I solve the problem ? I can't make any GET or POST request from qt.

What is the version of OpenSSL you are currently using on your system ?

How did you install Qt ?

What exact version is it ?

[hiren21]

I am noob in Qt so I think my code is not correct . I installed Qt 5.9.0. from official offline installer and openssl version is OpenSSL 1.0.2g 1 Mar 2016

Then first check with the distribution provided Qt so you'll be sure whether it's your code that has a problem.
