Codeigniter RESTful API-如何获取参数

Question

I have this model in my Codeigniter setup:

function get_all_artists(){

    $this->db->select('artist_id, artist_name');
    $this->db->from('artists');
    return $this->db->get();    
}

How do I fetch those parameters in my Rest_Controller setup? How would the _get() -function look like?

public function artists_get()  
{  
 ???
}

Thanks in advance

Answer 1

Try

public function artists_get(){  
  $this->load->model('your_model_name');// load model here
  $res = $this->your_model_name->get_all_artists();
  $result = $res->result_array();// get result as associative array
  return json_encode($result);// encode with json
}

With this library you need to append the method type to the function name. _get for GET , _post for POST , _put for PUT , _delete for DELETE . eg functionname_get() .

As noted in another answer you'll want to retrieve results as an array. So $this->db->get()->result_array(); To retrieve data from the model:

$this->load->model('model_name');

$artists = $this->model_name->get_all_artists();

If you want to send json to front end then you need to do something like this:

$vars['artists'] = json_encode($artists);

$this->_getTemplate('default')->build('artists_page', $vars);

Answer 3

If you are using the REST EXTENSION for CodeIgniter then you must create an object and invoke the method "Respose".

public function artists_get() {
  $response = array(
    'status'=>TRUE,
    'data'=>$result, // This can be an object or array
    'obs'=>'all',
  );
  $this->response($response);
}

That's the official way to do it... and it works perfectly!
