tp6参数获取的五种方法

1、当前类继承自BaseController

public function request(){
    dump($this->request->param());
    dump($this->request->get());
    dump($this->request->post());

    dump($this->request->param('id'));
    dump($this->request->param('id',0,'intval'));
    dump($this->request->param('ids'));
    dump($this->request->param('ids',3,'intval'));
}

2、当前类没有继承自BaseController

通过Request依赖注入

use appRequest;
public function index(Request $request){
    dump($request->param('abc'));
}

3、input

public function func2(){
    dump(input('abc'));
}

4、助手函数

public function func2(){
    dump(request()->param('abc'));
}

5、静态方式调用

public function func3(){
    dump(Request::param('abc'));
}
