PyQt5 QNetworkAccesManager SSL error

Navigation
0

I have a problem that I do not have with the solution, I am trying to access a site (https) using QNetworkAccesManager, I am Using PyQt5 (compiled by me) in Python 2.7.14 32Bit

my code is this: 

from PyQt5.QtCore import QUrl, QCoreApplication
from PyQt5.QtNetwork import QNetworkAccessManager, QNetworkRequest, QNetworkReply

app = QCoreApplication([])
nam = QNetworkAccessManager()
req = QNetworkRequest(QUrl('https://www.google.es'))
resp = nam.get(req)


def downloadProgress(bytesReceived, bytesTotal):
    print 'Descargado: %s de %s' %  (bytesReceived, bytesTotal)


def sslErrors(errors):
    for error in errors:
        print error.errorString()


resp.sslErrors.connect(sslErrors)
resp.downloadProgress.connect(downloadProgress)
app.exec_()

and this is what it shows me in the console: 

The host name did not match any of the valid hosts for this certificate
The signature of the certificate is invalid
The signature of the certificate is invalid
Descargado: 0 de 0

Any suggestions? I've tried everything I've seen out there but nothing seems to work.

EDIT:

I add this information in case it clarifies something:

Ok, I have already found the solution with the Qt compiled version and the one that was installed in the system did not match 

QSslSocket.sslLibraryVersionString()
QSslSocket.sslLibraryBuildVersionString()

I had to update the files libeay32.dll and ssleay32.dll of C:\Windows\SysWOW64 but my question is, can I tell Qt the openssl path if I want to use a different version than the one I have installed on the system?

What is happening to you is that the Qt libraries you are using link to openssl ... in a dynamic way. This means that you must have the openssl DLLs available on your computer and localized by Qt.

The most normal thing is that you have to find a version of openSSL compatible with the one expected by Qt or mount it by your own means (if they do not tell you anything, the best thing is to mount the latest stable version).

To avoid interference with other possible versions of the library, it is best to place your DLLs next to the executable, since that is where you first try to find the libraries.

This solution will prevent you from forgetting to take the DLLs with you when you take the executable to another computer.
