Use Laravel passport authentication in API - php

Question

I am using Laravel Passport Authentication in my project. I want to use passport authentication only in API so I am trying to generate client_id and client_secret using below code but it returns NULL
I have written this code in my routes/api.php
Route::post('/gen_client', function () {
$http = new GuzzleHttp\Client([
'headers' => [ 'Content-Type' => 'application/json' ]
]);
$response = $http->post(url('/') . '/oauth/clients',
['body' => json_encode(
[
'id' => 'ovais.khan#gmail.com',
'name' => 'Ovais2',
'redirect' => url('/') . '/callback'
]
)
]
);
$response_body = json_decode((string)$response->getBody(), true);
var_dump($response_body);
});
Suppose if I have generated client_id using command line php artisan passport:client
now I want to authorized access token but it returns NULL
Route::post('callback', function (Request $request) {
$http = new GuzzleHttp\Client();
$oauth_client = DB::table('oauth_clients')->where('id', '=', 'ovais.khan#gmail.com')->first();
$response = $http->post(url('/') . '/oauth/token', [
'form_params' => [
'grant_type' => 'authorization_code',
'client_id' => $oauth_client->id,
'client_secret' => $oauth_client->secret,
'redirect_uri' => url('/') . '/callback',
'code' => $request->code,
],
]);
$response_body = json_decode((string)$response->getBody(), true);
var_dump($response_body);
$access_token = $response_body['access_token'] ;
$refresh_token = $response_body['refresh_token'];
});
dd(url('/') . '/oauth/clients'); send me the output:
http://localhost/project/public/oauth/clients
dd($response); send me the output:

The reason you are getting NULL for $response_body is when you are setting the variable you are type hinting $response->getBody() as a string, what you are actually getting is an instance of Stream. Also you're trying to json_decode a class, not a json string. $response_body = json_decode((string)$response->getBody(), true); If you would like a JSON response you can do $response_body = $response->json();
For more information these sections of the GuzzleHttp docs will be really useful:
http://guzzle3.readthedocs.io/http-client/response.html#response-body and http://guzzle3.readthedocs.io/http-client/entity-bodies.html
