1. 传统调用
访问方式：http://127.0.0.1/demo/demo3/test?name=kk&age=22
<?php/*** Created by PhpStorm.* User: 10475* Date: 2018/8/27* Time: 22:59*/namespace app\demo\controller;use think\Request;class Demo3{public function test(){$request = new Request();dump($request->get());}}
2. 静态调用
Request在THINKPHP5.1中已经内置了静态代理类，可以直接使用
访问方式http://127.0.0.1/demo/demo3/test?name=kk&age=22&sex=male
<?php/*** Created by PhpStorm.* User: 10475* Date: 2018/8/27* Time: 22:59*/namespace app\demo\controller;use think\Facade\Request;class Demo3{public function test(){dump(Request::get());}}
3. 依赖注入，也就是类型约束
访问方式http://127.0.0.1/demo/demo3/test?name=kk&age=22&sex=male
<?php/*** Created by PhpStorm.* User: 10475* Date: 2018/8/27* Time: 22:59*/namespace app\demo\controller;use think\Request;class Demo3{public function test(Request $request){dump($request->get());}}
4. Controller类中的request属性
<?php/*** Created by PhpStorm.* User: 10475* Date: 2018/8/27* Time: 22:59*/namespace app\demo\controller;class Demo3 extends \think\Controller{public function test(){dump($this->request->get());}}
