Curently i tried to login using username and password from external api https://fakestoreapi.com/auth/login with HTTP client that if login success will recevie a token.

Now i have to make a error message and return back to login form if username and password wrong. But what i get still an error from laravel like Attempt to read property "token" on null. Please help me, i'm a beginner.

this is my controller code.

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

class MasukController extends Controller
{
    public function masuk()
    {
        return view('login');
    }

    public function cek(Request $request)
    {
        $request->validate([
            'username' => 'required',
            'password' => 'required',
        ]);

        // Send a POST request to the API
        $response = Http::post('https://fakestoreapi.com/auth/login', [
            'username' => $request->input('username'),
            'password' => $request->input('password'),
        ]);

        // Decode the response
        $data = json_decode($response);

        // Get the token from the response
        $token = $data->token;

        // Redirect to the dashboard page
        if (is_null($token)) {
            Session::flash('error', 'Error: Token is null');

            // Redirect the user back to the previous page
            return redirect()->back();
        } else {
            session(['token' => $token]);
            return redirect('/');
        }
    }
}

i want to show error message if username and password not match in login form.

CodePudding user response：

maybe you can use GuzzleHttp\Client when you execute post method.

for example using guzzlehttp below :

use GuzzleHttp\Client;

    public function PostData(Request $request)
    {
        $client = new Client();
        $username = $request->username;
        $password = $request->password;
            $url = 'https://yoururl.example'

        $params = [
            "username" => $username,
            "password" => $password
        ];

        $response = $client->request('POST', $url, [
            'json' => $params
        ]);

        return json_decode($response->getBody());
    }

Then you can dump & die / dd the response->getBody() for get output

CodePudding user response：

You are attempting to json_decode the entire $response object which will fail. There is easier way get this done:

Gets an array of all response data:

$data = $response->json();

To get just the token:

$token = $response->json('token')
