Operating ROS node from HTTP

edit

Hi Everyone,

What i want to do is to send the robot a destination goal from a website I created.

I already have a node that sends the robot the destination. i'm guessing that i need to make a node that listens to the http port and reads what link has been pressed on the website. and then start the node that I already have to send the location goal.

but how can i do that? any help would be much appreciated!
