How to use QWebSocket in SecureMode?

How to use QWebsocket with Securemode(SSL)？
i'm a amateur and i want to build a simple chatting tool by QWebsocket,but i found my server&client program could communicate with each other well while the server was NonSecuremode,but if i changed it to secure mode,my client can't connect to it.Anybody knows why?Thanks!
Here is the Server:

from PySide2.QtWebSockets import *
from PySide2.QtCore import *
from PySide2.QtWidgets import *


class A(QMainWindow):
    def __init__(self, parent=None):
        super(A, self).__init__(parent)
        self.server = QWebSocketServer('server', QWebSocketServer.SecureMode, parent)
        self.server.listen(QHostAddress.LocalHost, port=6666)
        self.server.newConnection.connect(self.handle)

    def handle(self):
        a = self.server.nextPendingConnection()
        print('there is a new client')

app = QApplication()
b = A()
b.show()

app.exec_()

Here is the Clinet:

from PySide2.QtWebSockets import *
from PySide2.QtCore import *
from PySide2.QtWidgets import *


class A(QMainWindow):
    def __init__(self, parent=None):
        super(A, self).__init__(parent)
        self.a = QWebSocket()
        self.a.open(QUrl('wss://127.0.0.1:6666'))



app = QApplication()
b = A()
b.show()
print(b.a.state())
app.exec_()

Hi and welcome to devnet,

What version of PySide2/PyQt5 are you using ?
On what OS ?

[zgjja]

@SGaist
PySide2 Version 5.15.0
OS Version Windows10--19041.330

Did you check whether you have the OpenSSL dlls available on your system ?

@zgjja you may want to check the SSL Echo Server example where (although in C++) you'll see how the secure server is created.

BTW, you'll need a server certificate (very likely a self-signed one) and a private key...

@Pablo-J-Rogina @SGaist
I checked the C++ code and i found that the WebSocketServer Class in C++ has a "setsslconfiguration" function while the Python doesn't have.If i construct a SSL certification like this:

        cacert_key = QFile('cacert.pem')
        priv_key = QFile('privkey.pem')
        server_config = QSslConfiguration()
        server_config.setLocalCertificate(cacert_key)
        server_config.setPrivateKey(priv_key)

but i don't know how to implement this to the WebScoketServer i build.
