CodeIgniter RESTful API库响应

Question

This question is related to the CodeIGniter RESTful API library found here. I hope someone here is using this library and can offer some help :) .

http://net.tutsplus.com/tutorials/php/working-with-restful-services-in-codeigniter-2/

I have installed this library and set up a working environment with it. I have been able to get data back as well. For use, I have created a very simple class that I am accessing with the following code:

<?php

 require APPPATH.'/libraries/REST_Controller.php';

 class Users extends REST_Controller
 {
      public function list_get()
      {
           $this->load->database();

           $data = $this->db->get('users')->result();

           $this->response($data, 200); 
       }

  }

To get at this controller, I have done a call to the following URL:

"http://localhost/mgtapp/index.php/api/users/list/format/json"

While I am getting back data, I see that the header content type is set to text/html instead of json and I am also getting errors in php that say "headers already sent". I have tried to remove the format from the end of the url and send it in via an "accept" but I get the same errors and I see the content type being set as text/html. When I run the example, I see the response coming back as it should (as json in the content type) so I do not understand what I am doing wrong here that the content type is not being set correctly. IF someone can shed some light it would be super helpful!

Thanks!

Answer 1

So I am answering this question because the reason for my troubles was a stupid one.

I had a couple of lines under the "?>" of my php class controller and apparently that was messing it up. Sorry!

Anybody else with this issue, check that first!
