yii2怎么调通接口(实例表单接口)：

理解这里的意思

第一：frontend里的config的文件夹里面新建一个rules.php文件

<?php
/**
 * Created by PhpStorm.
 * User: Chan
 * Date: 2018/6/8
 * Time: 14:14
 */

use yii\rest\UrlRule;

return [
    [
        'class'=>UrlRule::class,
         'controller' => 'user',

    ],
];

第二：创建一张表，并且gii自动生成.

第三步:

<?php
namespace frontend\controllers;
use yii\web\Controller;
use common\models\User;
use Yii;
class UserController extends Controller
{public $enableCsrfValidation = false;
    public function actionCreate()
    {
        $request = Yii::$app->request;
        $username = $request->post('username');
        $password = $request->post('password');
      Yii::$app->db->createCommand()->insert('user', [
    'username' => $username,
    'password' => $password,
])->execute();


        }

    }
