Use Laravel passport authentication in API

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
