connect to rest service with qt and error SSL handshake failed

[panagiotisss]

I am trying to connect to rest service that has ssl certificates. I have those certificates files(cacert.pem and another file .pem) locally.
For this purpose I use qt library.
I can connect to a rest service without certificates but I cannot connect to a service with certificates.

I try this code(having the certificate in the release folder of the project)


QNetworkAccessManager *m_network = new QNetworkAccessManager(this);

QNetworkRequest request;

QUrl wapi_url=QUrl("...");

wapi_url.setPort(8082);

request.setUrl(wapi_url);

QSslConfiguration SslConfiguration(QSslConfiguration::defaultConfigu ration());

QList<QSslCertificate> caList = SslConfiguration.caCertificates();

caList.append(QSslCertificate("cacert.pem")); //Root CA

SslConfiguration.setCaCertificates(caList);

SslConfiguration.setLocalCertificate(QSslCertifica te("bla_bla_server.pem"));

SslConfiguration.setProtocol(QSsl::SslV3);

SslConfiguration.setPeerVerifyMode(QSslSocket::Ver ifyPeer);

request.setSslConfiguration(SslConfiguration);
QNetworkReply *reply = m_network->get(request);

but I get a SSL handshake failed error.
Any idea how can I pass this error and connect to the rest service?

You could start by telling us what the error was (any text output and the QSslError value) and whether you have installed OpenSSL.

Yes I have installed OpenSSL.
I connect the QNetworkReply:networkerror with a method messageError like this

connect(reply, SIGNAL(error(QNetworkReply::NetworkError)), this,SLOT(messageError(QNetworkReply::NetworkError )));

and the error I get is "SSL handshake failed" and the number is 6
I also have added a connection like that

connect(m_network, SIGNAL(sslErrors(QNetworkReply , const QList<QSslError> &)), this, SLOT(sslError(QNetworkReply, const QList<QSslError> &)));

but my code doesn't go inside sslError method.
Any idea about that?

Thank you in advance!

[ChrisW67]

There is no SIGNAL or SLOT matching the signature"sslErrors(QNetworkReply , const QList<QSslError> &)". Perhaps you mean "sslErrors(QNetworkReply*,QList<QSslError>)" and are ignoring the warning printed in the console by connect().
For consistency you could use the sslErrors() signal from the reply object.

If there is a more general SSL library issue you will also see warnings about that in the output.

[panagiotisss]

I don't know if I have understand well what you have proposed.
I have added the following line

connect(reply, SIGNAL(sslErrors(QList<QSslError>)), this, SLOT(sslError2(const QList<QSslError>)));

but the execution of the program does not get inside sslError2 slot.

I have achieved to pass this error by copying msvcr120.dll and msvcp120.dll in to bin folder of openssl
But now I receive new errors
QSslSocket: cannot call unresolved function SSLv3_client_method
QSslSocket: cannot call unresolved function SSL_CTX_new
QSslSocket: cannot call unresolved function SSL_library_init
QSslSocket: cannot call unresolved function ERR_get_error

I have the test line of code in qt
qsslsocket::supportsssl()
that returns false

In my .pro file I have the qt+=network and I have also paste to qt bin folder the following dlls
libeay32.dll
libssl32.dll
ssleay32.dll

Any idea about that?
