ThinkPHP6 request

To use the request object, you must use the facade method (think\facade\Request class is responsible) to call
The detection, acquisition and security filtering of global input variables can be completed through the Request object
support$_GET、$_POST、$_REQUEST、$_SERVER、$_SESSION、$_COOKIE、$_ENV等系统变量，以及文件上传信息

1. Variable acquisition

serial number	method	illustrate
1	param	Get the variables of the current request
2	get	Get the $_GET variable
3	post	Get the $_POST variable
4	put	get PUT variable
5	delete	get DELETE variable
6	session	get session variables
7	cookie	Get the $_COOKIE variable
8	request	Get the $_REQUEST variable
9	server	Get the $_SERVER variable
10	env	Get the $_ENV variable
11	route	Get route (including PATHINFO) variables
12	middleware	Get the variables assigned/passed by middleware
13	file	Get the $_FILES variable
14	filter	variable filtering
15	only	Get some variables
16	except	Exclude some variables

1. GET request

The PARAM type 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
The param method will combine the parameters of the current request type with routing variables and GET requests, and routing variables are prioritized

controller code

public function edit(){
    
    
    print_r( $_GET );    // 原生get接收
    print_r( Request::param() ); // 获取当前请求的所有变量
    print_r( Request::param('id') );    // 获取当前请求的id变量
    print_r( Request::get() );
}

View code: index.html

<button class="layui-btn layui-btn-xs" onclick="edit({
      
      $right_v.id})">编辑</button>

<script type="text/javascript">
    function edit(id){
    
    
        layer.open({
    
    
            type: 2,
            title: '添加',
            shade: 0.3,
            area: ['480px', '440px'],
            content: '/index.php/index/edit?id='+id
        });
    }
</script>

2. POST request

controller code

public function edit(){
    
    
    $id = Request::param('id');
    $shop = Db::table('shop_goods')->where('id',$id)->find();
    $cat = Db::table('shop_cat')->where('status',1)->select();
    View::assign([
        'shop' => $shop,
        'cat' => $cat
    ]);
    return View::fetch();
}
public function edits(){
    
    
    // print_r( Request::param() );
    // print_r( Request::post() );

    $all = Request::param();
    $update = Db::table('shop_goods')->where('id',$all['id'])->update($all);
    if($update){
    
    
        echo json_encode(['code'=>0,'msg'=>'修改成功']);
    }else{
    
    
        echo json_encode(['code'=>1,'msg'=>'修改失败']);
    }
}
