This will load it into the Parameter Server and make the params available to your node. Now you can use getParam() to access those set params.

Thank you very much! I have solved the problems.I misunderstood the Parameter Server.Now I understand it . getParam() get params from Paramter Server ,no mater the params come from launch file or yaml file. thank you again.
Check this for cpp programming or this for python.
