Client testing issue for events service #13

Closed icedbeancat closed 1 week ago

icedbeancat commented 1 week ago

Hi @roleoroleo, thank you for your hard work.

I managed to successfully build the server and connect to the ONVIF Device Manager. I was able to post a GetEventProperties request. However, when I tried to create pullpoint subscription, ODM failed to do so. I did the same using the python-onvif-zeep client.

I only edited the IFS portions of the code since the interface that I am using is different. Else, I ran everything as is. Was I mistaken that the server can implement the full event service? I am not sure what I should check and which files I should modify.

Events service is supported: both PullPoint and WS base. Please, post your conf file.

Below is my conf file, I run it using lighttpd.

Configuration is ok. What type of error do you have?

Are you able to capture network traffic?

When testing with the ODM I got: Error during events subscription (unable to create pull point), so most likely a fault message reply. But when i access the logs at /var/log/onvif_simple_server.log, it is empty. Same for testing with python-onvif-zeep client:

During handling of the above exception, another exception occurred:

no visible errors.

When I tested with python-onvif-zeep client with this code:

from onvif import ONVIFCamera mycam = ONVIFCamera("192.168.1.109", 8080, "admin", "admin") device_srv = mycam.create_devicemgmt_service() events_srv = mycam.create_events_service() print(events_srv.GetServiceCapabilities())

i got this output: { '_value_1': None, 'WSSubscriptionPolicySupport': True, 'WSPullPointSupport': True, 'WSPausableSubscriptionManagerInterfaceSupport': False, 'MaxNotificationProducers': None, 'MaxPullPoints': None, 'PersistentNotificationStorage': None, '_attr_1': { } } [{ 'Name': 'VideoSourceConfig', 'UseCount': 2, 'SourceToken': 'VideoSourceToken', 'Bounds': { 'x': 0, 'y': 0, 'width': 1920, 'height': 1080 }, '_value_1': None, 'Extension': None, 'token': 'VideoSourceConfigToken', '_attr_1': { } }]

To enable debug log: echo 5 > /tmp/onvif_simple_server.debug You will find debug files in /var/log

Capturing network traffic helps debugging.
