我創建了一個帶有動作的簡單休息控制器，并嘗試通過 restclient mozilla 擴展發送發布數據。有一個問題，yii2 沒有看到所有的post 字段并且$_POST 是[]。請求方法是 POST，我肯定會發送數據。class ApiController extends Controller{    public function beforeAction($action)    {        $this->enableCsrfValidation = false;        Yii::$app->response->format = Response::FORMAT_JSON;        return parent::beforeAction($action);    }    public function actionAuth() {        Yii::$app->response->format = Response::FORMAT_JSON;        if(Yii::$app->request->isPost) {            $username = Yii::$app->request->post('username');            $password = Yii::$app->request->post('password');            $user = Players::find()                ->where(['username' => $username])                ->orWhere(['email' => $username])                ->one();            if($user->validatePassword($password)) {                $user->generateApiToken();                $user->save();                return ['status' => 'ok', 'message' => Yii::t('api', 'You are logged in successfully!'), 'data' => $user];            } else {                return ['status' => 'error', 'message' => Yii::t('api', 'Username or password is wrong.'), 'post' => $_POST];            }        }        else return ['status' => 'error'];    }}
