8.Yii2.0框架控制器接收get.post数据

一.get传参

 1 <?php
 2 /**

 7  * Time: 5:36
 8  */
 9 
10 namespace app\controllers;
11 
12 use yii\base\Controller;
13 
14 class HomeController extends Controller
15 {
16     public function actionIndex(){
17         $request = \Yii::$app->request;
18         //获取get传参
19         $id = $request->get('id',1); //默认不传参时为1
20         dump($id);
21         //获取post传参
22 //        $username = $request->post('username','xiaoli'); //默认不传参时为xiaoli
23 //        dump($username);
24 ////        return $this->render('index');
25     }
26 }

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:

 1 <?php
 2 /**
 3  * Created by Haima.
 4  * Author:Haima
 5  * QQ:228654416
 6  * Date: 2018/8/23
 7  * Time: 5:36
 8  */

10 namespace app\controllers;
11 
12 use yii\base\Controller;
13 
14 class HomeController extends Controller
15 {
16     public function actionIndex(){
17         $request = \Yii::$app->request;
18         //获取get传参
19 //        $id = $request->get('id',1); //默认不传参时为1
20 //        dump($id);
21         //获取post传参
22         $username = $request->post('username','xiaoli'); //默认不传参时为xiaoli
23         dump($username);
24 //        return $this->render('index');
25     }
26 }

打印效果

三.判断请求类型和用户IP:

 1 <?php
 2 /**
 3  * Created by Haima.
 4  * Author:Haima
 5  * QQ:228654416
 6  * Date: 2018/8/23
 7  * Time: 5:36
 8  */

10 namespace app\controllers;
11 
12 use yii\base\Controller;
13 
14 class HomeController extends Controller
15 {
16     public function actionIndex(){
17         $request = \Yii::$app->request;
18         //获取get传参
19 //        $id = $request->get('id',1); //默认不传参时为1
20 //        dump($id);
21         //获取post传参
22 //        $username = $request->post('username','xiaoli'); //默认不传参时为xiaoli
23         $get = $request->isGet; //判断get提交 返回 true/false
24         $post = $request->isPost; //判断post提交 返回 true/false
25         $ip = $request->UserIP; //获取用户IP
26 
27         vp($get);
28         vp($post);
29         vp($ip);
30 //        return $this->render('index');
31     }
32 }
