Examples of four calling modes of Request class in thinkPHP 5.1 framework

In this paper, four calling modes of Request class in thinkPHP 5.1 framework are described by examples. Share it for your reference, as follows:

1. Traditional invocation

Access method: 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. Static invocation

Request has built-in static proxy classes in THINKPHP 5.1, which can be used directly

Access method 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. Dependency injection, or type constraint

Access method 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. request attribute in Controller class

<?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());
   }
}
