8.Yii2.0框架控制器接收get.post数据

一.get传参

 <?php
 /**
  * Created by Haima.
  * Author:Haima
  * QQ:228654416
  * Date: 2018/8/23
  * Time: 5:36
  */

 namespace app\controllers;

 use yii\base\Controller;

 class HomeController extends Controller
 {
     public function actionIndex(){
         $request = \Yii::$app->request;
         //获取get传参
         $id = $request->get('id',1); //默认不传参时为
         dump($id);
         //获取post传参
 //        $username = $request->post('username','xiaoli'); //默认不传参时为xiaoli
 //        dump($username);
 ////        return $this->render('index');
     }
 }

get打印效果:

http://yii.com/index.php?r=home/index&id=6

这里的index可以不要

例:

http://yii.com?r=home/index&id=6

二.post传参:

 <?php
 /**
  * Created by Haima.
  * Author:Haima
  * QQ:228654416
  * Date: 2018/8/23
  * Time: 5:36
  */

 namespace app\controllers;

 use yii\base\Controller;

 class HomeController extends Controller
 {
     public function actionIndex(){
         $request = \Yii::$app->request;
         //获取get传参
 //        $id = $request->get('id',1); //默认不传参时为1
 //        dump($id);
         //获取post传参
         $username = $request->post('username','xiaoli'); //默认不传参时为xiaoli
         dump($username);
 //        return $this->render('index');
     }
 }

打印效果

三.判断请求类型和用户IP:

 <?php
 /**
  * Created by Haima.
  * Author:Haima
  * QQ:228654416
  * Date: 2018/8/23
  * Time: 5:36
  */

 namespace app\controllers;

 use yii\base\Controller;

 class HomeController extends Controller
 {
     public function actionIndex(){
         $request = \Yii::$app->request;
         //获取get传参
 //        $id = $request->get('id',1); //默认不传参时为1
 //        dump($id);
         //获取post传参
 //        $username = $request->post('username','xiaoli'); //默认不传参时为xiaoli
         $get = $request->isGet; //判断get提交 返回 true/false
         $post = $request->isPost; //判断post提交 返回 true/false
         $ip = $request->UserIP; //获取用户IP

         vp($get);
         vp($post);
         vp($ip);
 //        return $this->render('index');
     }
 }
