Thinkphp6 Getting Started (3)--Get parameter values of GET and POST requests

1. RequestObject

thinkphp provides Requestobjects, which can

Support detection, acquisition and security filtering of global input variables
Supports obtaining system variables including $_GET, $_POST, $_REQUEST, $_SERVER, $_SESSION, $_COOKIE, and file upload information$_ENV

Specific reference: https://www.kancloud.cn/manual/thinkphp6_0/1037519

2. All input parameters can be obtained through Request::param

PARAMType variable is a variable acquisition method provided by the framework to automatically identify the current request, and is the method recommended by the system to obtain request parameters.

Create a new html page

app/test/view/User/loginsimple.html

<!DOCTYPE html><html lang="en"><head></head><body>    <form method="post" action="/index.php/test/User/dologin?logintype=2" >        <input type="text" name="username"><br>        <input type="text" name="password"><br>        <input type="submit" value="提交">    </form>    </body>
</html>

Note: The submission path is /index.php/test/User/dologin/func/login?logintype=2

2. Create a new controller function

app\test\Controller\User.php

introduce

use think\facade\Request;

function

<?phpnamespace app\test\controller;
use app\BaseController;// 添加引用use think\facade\View;use think\facade\Request;
class User extends BaseController{
   
           // 登录页    public function loginsimple(){
   
           // 模板输出        return View::fetch('User/loginsimple');    }
    // 登录    public function dologin(){
   
           // 静态调用        // 获取当前请求get中的logintype变量        print_r(Request::param('logintype'));        print_r('<br/>');        // 获取当前请求get中的路径参数func变量        print_r(Request::param('func'));        print_r('<br/>');        // 获取当前请求post中的name变量        print_r(Request::param('username'));        print_r('<br/>');        // 获取当前请求的所有变量（经过过滤）        print_r(Request::param());        print_r('<br/>');        // 获取当前请求未经过滤的所有变量        print_r(Request::param(false));        print_r('<br/>');        // 获取部分变量        print_r(Request::param(['username', 'email']));    }
}

3. Test

After clicking submit

It can be seen that Request::param has successfully extracted the parameters in get, the path parameters in url, and the parameters in post
