Get list of topics via rosbridge and websocket
I am currently using rosbridge 2.0 to communicate with ROS via websocket. In connection with this I would like to retrieve a list of all topics through my interface. As I can read from the rosbridge website it should be possible to retrieve a list of topics currently running in ROS via a service call, however, I cannot figure out how this should be done since there are no examples. There is a link on the rosbridge website to a pdf with more information, but this link is unfortunately outdated and does not work.
