Question

I am using laravel 5.3 and angularjs
I submit json from my angularjs like below
{"grc":{"id":1},"floatingGrcs":[{"days":"10","units":"100"},{"days":"20","units":"200"}]}
I accept this array from my laravel controller like below
public function store(Request $request)
{
//how to extract $request object in here
}
I don't know how to extract submitted json array in laravel controller

Answer 1

You can use standard json_decode():
public function store(Request $request)
{
$data = json_decode($request->someJson);
}
You can look at all available data with dd($request->all());

Answer 2

The common-case is that there is no need to post json-encoded data through Angular.
To submit something with Angular, you should use, for example:
$http.post('api/something', {"grc":{"id":1},"floatingGrcs": [..]})
And then there is no need to decode json on the Laravel side:
public function store(Request $request)
{
$request->all(); // to get all fields
$request->grc->id; // to get a specific field
}

Answer 3

I got answer with below code. But i am not sure
$params = json_decode(file_get_contents('php://input'), TRUE);
is this above line of code secure or not.
public function store()
{
$params = json_decode(file_get_contents('php://input'), TRUE);
foreach ($params as $key => $value)
{
if($key == "grc")
{
$grc_id = $value["id"];
}
elseif($key == "floatingGrcs")
{
foreach ($value as $floating)
{
$days = $floating["days"];
}
}
}
