Missing fields error when making a post request in Laravel

Question

I am making a post request to the tiktok API, entering the 3 parameters that are requested, but when I carry out the request, it shows me the following: "Required fields are missing: app_id is required.", I attach an image:

enter image description here

but when performing the same procedure in postman if I have a positive response.

here is my code:

my route:

Route::get('callback-tiktok', [AuthsController::class, 'SocialAuth']);

my controller:

    <?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use GuzzleHttp\Client;
use GuzzleHttp\Exception\ClientException;

class AuthsController extends Controller
{

    public function SocialAuth(Request $request)
    {
        $a = $request->input('auth_code');
        // create a guzzle client object here
        $client = new Client();
        $respuesta = $this->client->request(
            'POST',
            'https://business-api.tiktok.com/open_api/v1.3/oauth2/access_token/',
            [
                'form_params' => [
                    'app_id' => '7112335319877287937',
                    'secret' => '18f52730856f43ed821187bfa9283794ca360ef1',
                    'auth_code' => $a
                ],
                'headers'  =>  [
                    'Content-Type'      =>  'application /json'
                ],
            ]
        );
        return response()->json($respuesta->getBody()->getContents());
    }
}

When compiling I get the following:

The stream or file "/home/epgutp/tiktok/storage/logs/laravel.log" could not be opened in append mode: Failed to open stream: Permission denied The exception occurred while attempting to log: The stream or file "/home/epgutp/tiktok/storage/logs/laravel.log" could not be opened in append mode: Failed to open stream: Permission denied The exception occurred while attempting to log: The stream or file "/home/epgutp/tiktok/storage/logs/laravel.log" could not be opened in append mode: Failed to open stream: Permission denied The exception occurred while attempting to log: The stream or file "/home/epgutp/tiktok/storage/logs/laravel.log" could not be opened in append mode: Failed to open stream: Permission denied The exception occurred while attempting to log: The stream or file "/home/epgutp/tiktok/storage/logs/laravel.log" could not be opened in append mode: Failed to open stream: Permission denied The exception occurred while attempting to log: The stream or file "/home/epgutp/tiktok/storage/logs/laravel.log" could not be opened in append mode: Failed to open stream: Permission denied The exception occurred while attempting to log: The stream or file....

Answer 1

I guess, you made some couple of errors, try this:

use GuzzleHttp\Client;
use GuzzleHttp\Exception\ClientException;
use Illuminate\Http\Request;

class AuthsController extends Controller
{
    public function SocialAuth(Request $request)
    {
        $a = $request->input('auth_code');
        // create a guzzle client object here
        $client = new Client();
        $respuesta = $this->client->request('POST', 
              'https://business-api.tiktok.com/open_api/v1.3/oauth2/access_token/',
             [
              'form_params' => [
                'app_id' => '711233531987728793',
                'secret' => '18f52730856f43ed821187bfa9283794ca360ef',
                'auth_code' => $a
              ], 
              'headers'  =>  [
                'Content-Type'      =>  'application /json'
              ],
          ]);
         return response()->json($respuesta->getBody()->getContents());
        
    }

}

Applying this solution gives me the following error:

Well, maybe this can help someone, solution to my question:

In this case use the Http facade:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Http;

class AuthsController extends Controller
{
    

    public function SocialAuth(Request $request)
    {

        $a = $request->input('auth_code');

        // URL
        $apiURL = 'https://business-api.tiktok.com/open_api/v1.3/oauth2/access_token/';

        // POST Data
        $postInput = [
            'app_id' => '7112335319877287',
            'secret' => '18f52730856f43ed821187bfa9283794ca360',
            'auth_code' => $a
        ];

        // Headers
        $headers = [
            //...
        ];

        $response = Http::withHeaders($headers)->post($apiURL, $postInput);

        $statusCode = $response->getStatusCode();
        $responseBody = json_decode($response->getBody(), true);

        echo $statusCode;  // status code

        dd($responseBody); // body response


    }
}

Response to my request:
