<?php
namespace app\index\controller;
// 1、导入Request
use think\Request;

class Index
{
    // 2、引入request
    public function index(Request $request)
    {
        // 3、这里就可以获取参数了
        var_dump($request);
        // 获取浏览器输入框里的值
        dump($request->domain());
        dump($request->pathinfo());
        dump($request->path());

        // 获取请求类型
        dump($request->method());
        dump($request->isGet());
        dump($request->isPost());
        dump($request->isAjax());

        // 获取请求参数
        dump($request->get());
            dump($request->get('id'));
            dump($request->get('name'));
        dump($request->post());
        dump($request->session());
        dump($request->cookie());
        dump($request->param());

        // 获取模块 控制器
        dump($request->module());
        dump($request->controller());
        dump($request->action());

        dump($request->url());
        dump($request->baseUrl());

        return view();
    }

}
