Laravel - POST data is null when using external request - php

Question

I'm new to laravel, and I'm trying to implement a simple rest api.
I have the controller implemented, and tested via unit testing.
My problem is with the POST request.
Via the tests Input:json has data, via an external rest client it returns null.
This is the code on the unit test
$newMenu = array(
'name'=>'Christmas Menu',
'description'=>'Christmas Menu',
'img_url'=>'http://www.example.com',
'type_id'=>1,
);
Request::setMethod('POST');
Input::$json = $newMenu;
$response = Controller::call('menu#index');
What am I doing wrong?
UPDATE:
This is realy driving me crazy
I've instanciated a new laravel project and just have this code:
Routes
Route::get('test', 'home#index');
Route::post('test', 'home#index');
Controller:
class Home_Controller extends Base_Controller {
public $restful = true;
public function get_index()
{
return Response::json(['test'=>'hello world']);
}
public function post_index()
{
return Response::json(['test'=>Input::all()]);
}
}
CURL call:
curl -H "Accept:application/json" -H"Content-type: application/json" -X POST -d '{"title":"world"}' http://localhost/laravel-post/public/test
response:
{"test":[]}
Can anyone point me to what is wrong.
This is really preventing me to use laravel, and I really liked the concept.

Answer 1

Because you are posting JSON as your HTTP body you don't get it with Input::all();
You should use:
$postInput = file_get_contents('php://input');
$data = json_decode($postInput, true);
$response = array('test' => $data);
return Response::json($response);
Also you can use
Route::any('test', 'home#index');
instead of
Route::get('test', 'home#index');
Route::post('test', 'home#index');

Answer 2

Remove header Content-type: application/json if you are sending it as key value pairs and not a json

Answer 3

If you use : Route::post('test', 'XYZController#test');
Send data format : Content-type : application/json
For example : {"data":"foo bar"}
And you can get the post (any others:get, put...etc) data with :
Input::get('data');
This is clearly written in here : http://laravel.com/docs/requests
. Correct Content-type is very important!
I am not sure your CURL call is correct. Maybe this can be helpful : How to POST JSON data with Curl from Terminal/Commandline to Test Spring REST?
I am using Input::get('data') and it works.

Answer 4

I was facing this problem, my response of post was always null. To solve that I put the body key in guzzle object, like this
$client = new Client([
'headers' => [
'Content-Type' => 'application/json',
'Authorization' => config('app.callisto_token'),
]
]);
$body = [
'firstResult'=> 0,
'data' => '05/05/2022'
];
$response = $client->post('http://'.$this->ip.'/IntegracaoERP'.'/status_pedido',
['body' => json_encode($body)]
);
Don't forget the json_encode in body key.
Hope this helps.
