Need some help with Process, cURL, and GET request on Yun

I currently have a database set up on a RaspPi, on which I have a table called “temphum1”. I want to send data to this table by using a GET request with the data inserted into the URL with cURL within a Process command.

Here is the two options I’m working on:

  Process p;

  p.begin("curl");
  p.addParameter("-X");
  p.addParameter("GET");
  p.addParameter("-g");
  p.addParameter("http://192.168.1.12/temphum1/put_data.php?reading=");
  p.addParameter("2014-08-03");
  p.addParameter("%2c");
  p.addParameter(String(h));
  p.addParameter("%2c");
  p.addParameter(String(t));
  p.addParameter("%2c");
  p.run();
  while(p.running());

and this:

  p.runShellCommand("curl -X GET -g http://192.168.1.12/temphum1/put_data.php?reading=2014-08-03%2c"+String(h)+"%2c"+String(t)+"%2c");

The “%2c” is the separator for the data, and the “h” and “t” variables are floats. To me, using “String(h)” and “String(t)” doesn’t give any errors while compiling, but I still don’t know if that will work. Plus I’m relatively new to cURL and Process.

Thanks for your time,
