Transform string to json in Laravel api

Question

Two month ago, i created an api in laravel and tested it with postman. Everything worked fine. Now i would continue to develop, but i can't access the elements like before.

Postman:

Body:

{
   "RFQ" : "123",
   "client_id": "2",
   "ITEMS": [
      {
         "material" : "1.234.565",
         "description" : "Test material 1",
         "quantity" : "2.123",
         "Quot. Deadline" : "2018-01-12",
         "delivery_date" : "2018-01-12",
      },
      {
         "material" : "9.87564.2",
         "description" : "Test material 2",
         "quantity" : "4",
         "Quot. Deadline" : "2018-01-12",
         "delivery_date" : "15.01.2018"
      }
   ]
}

Controller:

public function import(ImportRequestForQuoteRequest $request, $id)
{
   return $request->getContent();
}

Before, i was able to get as example the client_id like $request->client_idbut now it returns nothing.

If i return $request->getContent()i get a string like the body.

What i have to do to access the values?

what does dd($request->all()); return?

Try to return it like this

public function import(ImportRequestForQuoteRequest $request, $id)
{
   return response()->json($request->getContent());
}

The example is only to test if i can access the values. I like to access the value of client_id to work with it in the controller.

My bad, i miss understood the quesiton @bmatovu answer says pretty much how you can access those parameters. if those don't work, you can always run them through json_encode

You can try this in you controller...

use Illuminate\Http\Request;

public function myFunction(Request $request, $id)
{
   $post_param = $request->post_param;

   $default = '';
   $post_param = $request->input('client_id', $default);

   $route_param = $id;

    return response()->json(['params' => $request->all()]);
}

If I return return $request->client_id; there is no output even return $request->getContent() shows the full content

bmatovu Over a year ago

Try dd($request->all()) to see what parameters are being passed to the function

Peter Over a year ago

dd($request->all()) return nothing

Peter Over a year ago

dd(request->getContent()) returns the body text:

""" {\n   "RFQ" : "123",\n   "client_id": "2",\n   "ITEMS": [\n     {\n       "material" : "1.234.565",\n       "description" : "Test material 1",\n       "quantity" : "2.123",\n       "Quot. Deadline" : "2018-01-12",\n       "delivery_date" : "2018-01-12",\n   \n     },\n    {\n       "material" : "9.87564.2",\n       "description" : "Test material 2",\n       "quantity" : "4",\n       "Quot. Deadline" : "2018-01-12",\n       "delivery_date" : "15.01.2018"\n   \n     }\n   ]\n } """

you need to decode json to php array and then you able to access like normal array in php

$item = json_decode($request->ITEMS);

It returns null

Ravindra Bhanderi Over a year ago

so you first check data come from request or not through dd() function

Peter Over a year ago

No difference. It returns still null

Ravindra Bhanderi Over a year ago

Your Body:

{
   "RFQ" : "123",
   "client_id": "2",
   "ITEMS": [
      {
         "material" : "1.234.565",
         "description" : "Test material 1",
         "quantity" : "2.123",
         "Quot. Deadline" : "2018-01-12",
         "delivery_date" : "2018-01-12",
      },
      {
         "material" : "9.87564.2",
         "description" : "Test material 2",
         "quantity" : "4",
         "Quot. Deadline" : "2018-01-12",
         "delivery_date" : "15.01.2018"
      }
   ]
}

Change with :

{
   "RFQ" : "123",
   "client_id": "2",
   "ITEMS": [
      {
         "material" : "1.234.565",
         "description" : "Test material 1",
         "quantity" : "2.123",
         "Quot. Deadline" : "2018-01-12",
         "delivery_date" : "2018-01-12"
      },
      {
         "material" : "9.87564.2",
         "description" : "Test material 2",
         "quantity" : "4",
         "Quot. Deadline" : "2018-01-12",
         "delivery_date" : "15.01.2018"
      }
   ]
}

json array should be well-formed. So try to remove comma from array at "delivery_date" of first item. and you will get results using $request->all().

Hope this solves.

JSON is actually allowed to have trailing commas.

I did the same request with the php storm REST Client. With the same body and headers, everything works fine. Postman adds before and after the content """ I don't know why. So the error is anywhere in Postman
