Installation

To get the latest version of API Response, simply require the project using Composer:

$ composer require andrey-helldar/api-response

This command will automatically install the latest version of the package for your environment.

Instead, you may of course manually update your require block and run composer update if you so choose:

{
    "require": {
        "andrey-helldar/api-response": "^6.0"
    }
}

Alright! Use api_response() helper.

Using

Use with data key

as NULL with code:

return api_response(null, 304);

return with code 304:

{
    "data": null
}

[ to top ]

as integer with default code:

return api_response(304);

return with code 200:

{
    "data": 304
}

[ to top ]

as string with default code:

return api_response('qwerty');

return with code 200:

{
    "data": "qwerty"
}

[ to top ]

as string with code:

return api_response('qwerty', 400);

return with code 400:

{
  "error": {
    "type": "Exception",
    "data": "qwerty"
  }
}

[ to top ]

as integer with code:

return api_response(304, 400);

return with code 400:

{
  "error": {
    "type": "Exception",
    "data": 304
  }
}

[ to top ]

as array:

$data = [
    [
        'title' => 'Title #1',
        'description' => 'Description #1',
    ],
    [
        'title' => 'Title #2',
        'description' => 'Description #2',
    ],
];

[ to top ]

as error

return api_response($data, 400);

return with code 400:

{
  "error": {
    "type": "Exception",
    "data": [
      {
        "title": "Title #1",
        "description": "Description #1"
      },
      {
        "title": "Title #2",
        "description": "Description #2"
      }
    ]
  }
}

[ to top ]

as success

return api_response($data, 200);

return with code 200:

{
    "data": [
        {
            "title": "Title #1",
            "description": "Description #1"
        },
        {
            "title": "Title #2",
            "description": "Description #2"
        }
    ]
}

If the first parameter is a number, then the decryption of the error by code will be return. In other cases, the value of the passed variable will be return.

[ to top ]

with additional content

return api_response('title', 200, ['foo' => 'bar']);

return with code 200:

{
  "data": "title",
  "foo": "bar"
}

return with code 400:

{
  "error": {
    "type": "Exception",
    "data":"ok"
  },
  "foo": "bar"
}

return api_response(['data' => 'foo', 'bar' => 'baz']);

return with code 200:

{
  "data": "foo",
  "bar": "baz"
}

return with code 400:

{
  "error": {
    "type": "Exception",
    "data":"foo"
  },
  "bar": "baz"
}

Use without data key

If you do not want to wrap the response in the data key, then you need to pass the false value to the 5th parameter of the function:

use Helldar\ApiResponse\Services\Response;
use Symfony\Component\HttpFoundation\JsonResponse;

/**
 * Return a new response from the application.
 *
 * @param  mixed|null  $data
 * @param  int  $status_code
 * @param  array  $with
 * @param  array  $headers
 * @param  bool  $use_data
 *
 * @return Symfony\Component\HttpFoundation\JsonResponse
 */
function api_response(
    $data = null,
    int $status_code = 200,
    array $with = [],
    array $headers = [],
    bool $use_data = true
)
{
    return Response::init()
        ->data($data, $status_code, $use_data)
        ->with($with)
        ->headers($headers)
        ->response();
}

as NULL with code and without data key:

return api_response(null, 304, [], [], false);

return with code 304:

{}

[ to top ]

as integer with default code and without data key:

return api_response(304, 200, [], [], false);

        'title' => 'Title #2',

      {
        "title": "Title #2",
        "description": "Description #2"
      }
    ]
  }
}

[ to top ]

as success and without data key

return api_response($data, 200, [], [], false);

Returning exception instances

class FooException extends \Exception
{
    public function __construct()
    {
        parent::__construct('Foo', 405);
    }
}

class BarException extends \Exception
{
    public function __construct()
    {
        parent::__construct('Bar', 0);
    }
}

$foo = new FooException();
$bar = new BarException();

return api_response($foo);

return with code 405:

{
  "error": {
    "type": "FooException",
    "data": "Foo"
  }
}

return api_response($foo, 408);

return with code 408:

{
  "error": {
    "type": "FooException",
    "data": "Foo"
  }
}

return api_response($bar);

return with code 400:

{
  "error": {
    "type": "BarException",
    "data": "Bar"
  }
}

return api_response($bar, 408);

return with code 408:

{
  "error": {
    "type": "BarException",
    "data": "Bar"
  }
}

You can also add additional data:

return api_response($foo, 405, ['foo' => 'Bar']);
// or
return api_response($foo, 0, ['foo' => 'Bar']);

return with code 405:

{
  "error": {
    "type": "FooException",
    "data": "Foo"
  },
  "foo": "Bar"
}

Best practice use with the Laravel and Lumen Frameworks

If you use the Laravel or Lumen framework, you can update the extends in the app\Exceptions\Handler.php file to Helldar\ApiResponse\Support\LaravelException.

If you did not add anything to this file, then delete everything properties and methods.

As a result, a clean file will look like this:

<?php

namespace App\Exceptions;

use Helldar\ApiResponse\Support\LaravelException as ExceptionHandler;

class Handler extends ExceptionHandler
{
    //
}

Or you can change this file by adding code to it, similar to ours.
