Error while getting authenticated user in Laravel using JWT - php

Question

I was able to login and get user token using JWT in laravel.However, while tring to get authenticated user (getAuthUser) by passing that token, I get following error:
"SQLSTATE[42S22]: Column not found: 1054 Unknown column '' in 'where
clause' (SQL: select * from user where `` = 12 limit 1)"
AuthenticationController:
<?php
namespace Modules\Authentication\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Auth;
use App\Http\Requests;
use JWTAuth;
use JWTAuthException;
use Modules\Settings\Entities\Users;
use Modules\Authentication\Http\Requests\Authentication;
class AuthenticationController extends Controller
{
public function __construct()
{
// $this->user = new Users;
$this->guard = \Auth::guard('api');
}
public function login(Authentication $request){
$credentials = $request->only('username', 'password');
try {
// verify the credentials and create a token for the user
$token = JWTAuth::attempt($credentials);
if (! $token = JWTAuth::attempt($credentials)) {
return response()->json(['error' => 'invalid_credentials'], 401);
}
} catch (JWTException $e) {
// something went wrong
return response()->json(['error' => 'could_not_create_token'], 500);
}
// if no errors are encountered we can return a JWT
return response()->json(compact('token'));
}
public function getAuthUser(Request $request){
$user = JWTAuth::user($request->token);
// dd($user);
return response()->json(['result' => $user]);
}
}
Users Model:
namespace Modules\Settings\Entities;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Contracts\Auth\Authenticatable;
use Tymon\JWTAuth\Contracts\JWTSubject;
class Users extends Model implements JWTSubject,Authenticatable{
Protected $table="user";
// protected $primaryKey = 'id';
protected $fillable = ['id','username','password','user_status_type_id','client_id','created_userid'];
protected $hidden = [
'password', 'remember_token',
];
public function user_status(){
return $this->belongsTo('Modules\Settings\Entities\UserStatusType','user_status_type_id');
}
public function user_client(){
return $this->belongsTo('Modules\Settings\Entities\Client','client_id');
}
public function role()
{
return $this->belongsToMany('Modules\Settings\Entities\Role','user_role','user_id','role_type_id');
}
public function getAuthPassword() {
return $this->password;
}
public function getJWTIdentifier() {
return $this->getKey();
}
public function getJWTCustomClaims()
{
return [];
}
public function getAuthIdentifierName(){}
public function getAuthIdentifier(){}
// public function getAuthPassword(){}
public function getRememberToken(){}
public function setRememberToken($value){}
public function getRememberTokenName(){}
}
Route:
Route::group(['middleware' => 'web', 'prefix' => 'api/v1/authentication', 'namespace' => 'Modules\Authentication\Http\Controllers'], function(){
Route::post('auth/login', 'AuthenticationController#login');
// Route::group(['middleware' => 'jwt.auth'], function () {
Route::get('user', 'AuthenticationController#getAuthUser');
// });
});
I am testing it in postman by
GET: ..../api/v1/authentication/user?token={Token}
EDIT:
Now my method for getAuthUser in the controller looks like this:
public function getAuthUser(Request $request){
// $token = JWTAuth::getToken();
// dd($token);
$input = $request->all();
JWTAuth::setToken($input['token']);
// dd($input['token']);
$user = JWTAuth::toUser($input['token']);
// dd($user);
return response()->json(['result' => $user]);
}
and In JWTAuth.php
public function authenticate()
{
// dd($this->getPayload()->get('sub'));
$id = $this->getPayload()->get('sub');
// dd($id);
// dd($this->auth->byId($id));
if (! $this->auth->byId($id)) {
return false;
}
return $this->user();
}
here by doing dd($id), value of id comes but if I try to do dd($this->auth->byId($id)) I get the same error as before.

Try this to retrieve the user instead:
public function getAuthUser()
{
try {
if (! $user = JWTAuth::parseToken()->authenticate()) {
return response()->json(['user_not_found'], 404);
}
} catch (Tymon\JWTAuth\Exceptions\TokenExpiredException $e) {
return response()->json(['token_expired'], $e->getStatusCode());
} catch (Tymon\JWTAuth\Exceptions\TokenInvalidException $e) {
return response()->json(['token_invalid'], $e->getStatusCode());
} catch (Tymon\JWTAuth\Exceptions\JWTException $e) {
return response()->json(['token_absent'], $e->getStatusCode());
}
// the token is valid and we have found the user via the sub claim
return response()->json(['result' => $user]);
}
Taken from docs, Retreiving the Authenticated user from a token
EDIT:
May not make a difference but just looking at your Model again and I would say that it needs to be
class Users extends Authenticatable implements JWTSubject
rather than
class Users extends Model implements JWTSubject,Authenticatable
