yii2 custom REST api issue - api

Question

I have tried all the way to make these run but no use.There is lots of problem and confusion i m going through.
I have make api which return all the countries which is working fine.Now need to write api function to list all the states of perticular country.
api : http://phpserver:8090/ssn-project/newzit/api/web/state/customstate?country_id=102
StateController.php
class StateController extends ActiveController{
public $modelClass = 'api\modules\state\models\State';
public function actionCustomState($country_id)
{
$model = new $this->modelClass;
$result = $model::find()
->where(['country_id' => $country_id])
->all();
return $result;
}
}
main.php
'urlManager' => [
'enablePrettyUrl' => true,
'enableStrictParsing' => true,
'showScriptName' => false,
'rules' => [
[
'class' => 'yii\rest\UrlRule',
'controller' => ['country/country','state/state','category/category','seller/seller'],
'extraPatterns' => [
'GET CustomState' => 'CustomState',
],
]
],
]
Am I doing anything wrong.Please help

Answer 1

What do you mean by 'controller' => ['country/country','state/state','category/category','seller/seller'] ? This will be treated as module/controller. You have placed all controllers inside different modules? With this logic, your api url will be
http://phpserver:8090/ssn-project/newzit/api/web/state/state/customstate?country_id=102
instead of
http://phpserver:8090/ssn-project/newzit/api/web/state/customstate?country_id=102

Found the solution.
made 'pluralize'=>false and used custom-state in url
My main.php
'rules' => [
[
'pluralize'=>false,
'class' => 'yii\rest\UrlRule',
'controller' => ['country/country','state/state','category/category','seller/seller','contactus/contactus'],
'extraPatterns' => [
'GET custom-state' => 'custom-state',
],
]
],
Thank you.
