JSON PHP formatting Jackson parsing POJO

I am using CodeIgniter for some small REST WS, and can not get a properly (as viewed from Jackson parser point of view) formatted JSON output. For Jackson to do it, the output needs to be something like:

{ "recipes": 
    [ 
        {
            "name":"Recipe 1",
            "id":"8aecfd9b2fa26e83012fa298c2a50017",
            "recipe":"1 Lorem ipsum...",
        }, 
        { 
            "name":"Recipe 2",
            "id":"8aecfd9b2fa26e83012fa298c2a90018",
            "recipe":"2 Lorem ipsum...",
        },
        {
            "name": "Recipe 3",
            "id":"8aecfd9b2fa26e83012fa298c2ae0019",
            "recipe":"3 Lorem ipsum...",
        } 
    ]
}

And using the code in CodeIgniter controller like:

        $allEecipes['recipes'] = array(
                    array('name' => 'Recipe 1', 'id' => '8aecfd9b2fa26e83012fa298c2a50017', 'recipe' => '1 Lorem ipsum...'),
                    array('name' => 'Recipe 2', 'id' => '128aecfd9b226e83012fa298c2a50017', 'recipe' => '1 Lorem ipsum...'),
                    array('name' => 'Recipe 3', 'id' => '34ecfd9b2fa26e83012fa298c2a50017', 'recipe' => '1 Lorem ipsum...'),
        );      

        $this->response($allEecipes, 200); // 200 being the HTTP response code

I get the following JSON output:

[
  [
    {
      "name": "Recipe 1",
      "id": "8aecfd9b2fa26e83012fa298c2a50017",
      "recipe": "1 Lorem ipsum..."
    },
    {
      "name": "Recipe 2",
      "id": "128aecfd9b226e83012fa298c2a50017",
      "recipe": "1 Lorem ipsum..."
    },
    {
      "name": "Recipe 3",
      "id": "34ecfd9b2fa26e83012fa298c2a50017",
      "recipe": "1 Lorem ipsum..."
    }
  ]
]

Notice the brackets, and the missing name for an array. How to get things right? I suppose the PHP encode_to_json is doing it's job correctly.

EDITED: Still no luck, after adding class like

class Eecipes
{
    public $recipes;

    public function __construct()
    {
    }
}

And creating it like

    $allEecipes = new Eecipes();
    $allEecipes-> recipes = array(
        array('name' => 'Recipe 1', 'id' => '8aecfd9b2fa26e83012fa298c2a50017', 'recipe' => '1 Lorem ipsum...'),
        array('name' => 'Recipe 2', 'id' => '128aecfd9b226e83012fa298c2a50017', 'recipe' => '1 Lorem ipsum...'),
        array('name' => 'Recipe 3', 'id' => '34ecfd9b2fa26e83012fa298c2a50017', 'recipe' => '1 Lorem ipsum...'),
        );
$this->response($allEecipes, 200);

The output I get is

{
  "recipes": {
    "0": {
      "name": "Recipe 1",
      "id": "8aecfd9b2fa26e83012fa298c2a50017",
      "recipe": "1 Lorem ipsum..."
    },
    "1": {
      "name": "Recipe 2",
      "id": "128aecfd9b226e83012fa298c2a50017",
      "recipe": "1 Lorem ipsum..."
    },
    "2": {
      "name": "Recipe 3",
      "id": "34ecfd9b2fa26e83012fa298c2a50017",
      "recipe": "1 Lorem ipsum..."
    }
  }
}

So, still not as needed. No angled brackets [, and the numbers are not needed. And the result in online JSON viewer shows the difference, too

Solution

  • Try encoding your result yourself with json_encode and then send the result ? Look at the flag options of json_encode, JSON_FORCE_OBJECT might help you
