Changing Application URI in client object

[mikelga]

Hello,
I want to use python-opcua as a client to connect to an OPC-UA server (UA CPP Server). I want to communicate using the security configuration Basic256Sha256 and Sign&Encrypt. After using the function
client.set_security(getattr(security_policies, 'SecurityPolicy' + 'Basic256Sha256'),"/home/ii40asset/klabeak/Python-opcua client/python_client.der","/home/ii40asset/klabeak/Python-opcua client/python_client_key.pem",mode=ua.MessageSecurityMode.SignAndEncrypt)

I see this error in the client:
The URI specified in the ApplicationDescription does not match the URI in the certificate.(BadCertificateUriInvalid)

On the server after clicking on Disable ApplicationURI check, the client works perfectly for me.
But I want to enable again ApplicationURI check.

How can I change this ApplicationURI in the client?

Thanks

look at members of client class, there is one called application_uri for example. But I really do not know what your server wants. Write it down in that bug when you find out

Hi,

I think that I need to write urn:Mikel-PC:UnifiedAutomation:UaServerCpp in application_uri.

I found this in client.py, but I don't know how I can change it:

This appears in the server features:

Thank you!

I think you can just change that attribute.

my_client = Client('some url')
my_client.application_uri = "my URI"
