@LPMadness can't you hook into the $request and do a before filter like this
if (!isset($request['date'])) {
$request['date'] = date('c');
}
return $next($request);

Add additional data to Rest response
Hi everyone,
While L5 was still in development I used the middlewares to add additional data after each rest response like this:
$response = $next($request);
if (!isset($response['date'])) {
$response['date'] = date('c');
}
return $response;
After the official release Taylor changed some stuff and the response content is build before it hits the middleware. I can make it work with decoding the response content, adding the additional parameter and encoding it again, but it's the same job done twice. Is there a neater way do it?

@bjorntheart it will run before the action. Nonsense.

@pmall thanks for your useful reply. Do you have any better suggestions or an actual solution to the problem

Ok @LPMadness, I think this might help you.
I create a Middleware called AddToRequest and registered it in Kernel.php. See the code below
AddToRequest.php
<?php namespace App\Http\Middleware;
use Carbon\Carbon;
use Closure;
class AddToRequest {
/**
* Handle an incoming request.
*
* @param \Illuminate\Http\Request $request
* @param \Closure $next
* @return mixed
*/
public function handle($request, Closure $next)
{
$request->request->add(['dummy' => 'hey man', 'date' => Carbon::now()]);
return $next($request);
}
}
Kernel.php
<?php namespace App\Http;
use Illuminate\Foundation\Http\Kernel as HttpKernel;
class Kernel extends HttpKernel {
/**
* The application's global HTTP middleware stack.
*
* @var array
*/
protected $middleware = [
'Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode',
'Illuminate\Cookie\Middleware\EncryptCookies',
'Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse',
'Illuminate\Session\Middleware\StartSession',
'Illuminate\View\Middleware\ShareErrorsFromSession',
'App\Http\Middleware\VerifyCsrfToken',
];
/**
* The application's route middleware.
*
* @var array
*/
protected $routeMiddleware = [
'auth' => 'App\Http\Middleware\Authenticate',
'auth.basic' => 'Illuminate\Auth\Middleware\AuthenticateWithBasicAuth',
'guest' => 'App\Http\Middleware\RedirectIfAuthenticated',
'inject' => 'App\Http\Middleware\AddToRequest'
];
}
In the handle() method of the AddToRequest Middleware, I set two variables and add it to the request
$request->request->add(['dummy' => 'hey man', 'date' => Carbon::now()]);
Then, in my controller I use the inject middleware
public function __construct()
{
$this->middleware('inject');
$this->middleware('guest');
}
In the index() method of the controller I inject the use Illuminate\Http\Request object and pull the variables I set in the middleware from the request object as follows:
public function index(Request $request)
{
dd($request->get('dummy'), $request->get('date'));
return view('welcome');
}
I hope that helps :-)

@bjorntheart Sometimes the rest functionality is doing complex calculations so I need to add it after the request is processed. I use the datetime as a last activity record from the server for lots of other stuff like: execution time, cache, is alive checks, logging, etc. I am also adding other parameters to the response that my API needs, but in order to keep things simple I just showed the datetime filter as an example to what I am trying to achieve.

@LPMadness hey, just noticed your reply after mine. Does what I posted help at all, or am I missing something?
Level 8
@bjorntheart Not really because this adds parameter to the request. I need to add such to the response.

@LPMadness ah damn! Sorry bro. Totally misunderstood it then :P
