I am a newbie here, just started working on ROS a week ago. Is there any way to record /save some data into a simple text file directly from the server or client? I want to record the request received by the server, alternatively can anybody give example of this implemented by rosbag ? The basic c++ methods of fstream and ofstream do not work in ROS.
1) See this question for how to convert ROS messages to text file from the command line.
2) Here is a good introduction to the rosbag API.
3) fstream and ofstream do work in ROS. All ROS nodes are still C++ executables. I've used fstream and ofstream many times for simple logging in my ROS nodes.
4) ROS also logs all ROS print statements (ROS_INFO) to log files. Mine are located in ~/.ros/log. Files called {node}-{number}-stdout.log contain this information.
