I know this post is kind of old but I just made a Middleware that replaces the "Accept" header of the request with "application/json". This makes the wantsJson() function return true when used. (This was tested in Laravel 5.2 but I think it works the same in 5.1)

Here's how you implement that :

1. Create the file app/Http/Middleware/Jsonify.php

   namespace App\Http\Middleware;
   
   use Closure;
   
   class Jsonify
   {
   
       /**
        * Change the Request headers to accept "application/json" first
        * in order to make the wantsJson() function return true
        *
        * @param  \Illuminate\Http\Request  $request
        * @param  \Closure  $next
        * 
        * @return mixed
        */
       public function handle($request, Closure $next)
       {
           $request->headers->set('Accept', 'application/json');
   
           return $next($request);
       }
   }
   

2. Add the middleware to your $routeMiddleware table of your app/Http/Kernel.php file

   protected $routeMiddleware = [
       'auth'       => \App\Http\Middleware\Authenticate::class,
       'guest'      => \App\Http\Middleware\RedirectIfAuthenticated::class,
       'jsonify'    => \App\Http\Middleware\Jsonify::class
   ];
   

3. Finally use it in your routes.php as you would with any middleware. In my case it looks like this :

   Route::group(['prefix' => 'api/v1', 'middleware' => ['jsonify']], function() {
       // Routes
   });
