Registering User with Laravel Passport

In your API create route as

Route::post('register','Api\UsersController@create');

And in UsersController create method create()

function create(Request $request){    /**     * Get a validator for an incoming registration request.     *     * @param  array  $request     * @return \Illuminate\Contracts\Validation\Validator     */    $valid = validator($request->only('email', 'name', 'password','mobile'), [        'name' => 'required|string|max:255',        'email' => 'required|string|email|max:255|unique:users',        'password' => 'required|string|min:6',        'mobile' => 'required',    ]);    if ($valid->fails()) {        $jsonError=response()->json($valid->errors()->all(), 400);        return \Response::json($jsonError);    }    $data = request()->only('email','name','password','mobile');    $user = User::create([        'name' => $data['name'],        'email' => $data['email'],        'password' => bcrypt($data['password']),        'mobile' => $data['mobile']    ]);    // And created user until here.    $client = Client::where('password_client', 1)->first();    // Is this $request the same request? I mean Request $request? Then wouldn't it mess the other $request stuff? Also how did you pass it on the $request in $proxy? Wouldn't Request::create() just create a new thing?    $request->request->add([        'grant_type'    => 'password',        'client_id'     => $client->id,        'client_secret' => $client->secret,        'username'      => $data['email'],        'password'      => $data['password'],        'scope'         => null,    ]);    // Fire off the internal request.     $token = Request::create(        'oauth/token',        'POST'    );    return \Route::dispatch($token);}

And after creating new user, return access token.

And after I year, I figured out how to implement the full cycle.

@Nileshsinh method shows the register cycle.

And here is login & refresh token parts:

Route::post('auth/token', 'Api\AuthController@authenticate');Route::post('auth/refresh', 'Api\AuthController@refreshToken');

Methods:

class AuthController extends Controller{    private $client;    /**     * DefaultController constructor.     */    public function __construct()    {        $this->client = DB::table('oauth_clients')->where('id', 1)->first();    }    /**     * @param Request $request     * @return mixed     */    protected function authenticate(Request $request)    {        $request->request->add([            'grant_type' => 'password',            'username' => $request->email,            'password' => $request->password,            'client_id' => $this->client->id,            'client_secret' => $this->client->secret,            'scope' => ''        ]);        $proxy = Request::create(            'oauth/token',            'POST'        );        return \Route::dispatch($proxy);    }    /**     * @param Request $request     * @return mixed     */    protected function refreshToken(Request $request)    {        $request->request->add([            'grant_type' => 'refresh_token',            'refresh_token' => $request->refresh_token,            'client_id' => $this->client->id,            'client_secret' => $this->client->secret,            'scope' => ''        ]);        $proxy = Request::create(            'oauth/token',            'POST'        );        return \Route::dispatch($proxy);    }}

Reading this while Laravel 6 has recently been deployed, my solution for this is as following.

When you've followed the steps defined in Laravel's passport documentation and you added the HasApiTokens trait to the User model, you can call a createToken function on your user entities.

Also, in your RegisterController there's a registered function from the RegistersUsers trait that you can implement which is called when a user is successfully registered. So you could implement this as following:

protected function registered(Request $request, User $user){    $token = $user->createToken('tokenName');    return response()->json([        'user' => $user,        'token' => $token->accessToken,    ]);}

See the register function in the RegistersUsers trait for more information about the registration cycle..
