6.【TP6学习笔记】tp中Request请求对象调用详解

ThinkPHP6 请求

要使用请求对象必须使用门面方式（ think\facade\Request类负责）调用
可以通过Request对象完成全局输入变量的检测、获取和安全过滤
支持$_GET、$_POST、$_REQUEST、$_SERVER、$_SESSION、$_COOKIE、$_ENV等系统变量，以及文件上传信息

一、变量获取

方法	说明
param	获取当前请求的变量
get	获取 $_GET 变量
post	获取 $_POST 变量
put	获取 PUT 变量
delete	获取 DELETE 变量
session	获取 SESSION 变量
cookie	获取 $_COOKIE 变量
request	获取 $_REQUEST 变量
server	获取 $_SERVER 变量
env	获取 $_ENV 变量
route	获取路由（包括PATHINFO）变量
middleware	获取中间件赋值/传递的变量
file	获取 $_FILES 变量

1、GET 请求

PARAM类型变量是框架提供的用于自动识别当前请求的一种变量获取方式，是系统推荐的获取请求参数的方法
param方法会把当前请求类型的参数和路由变量以及GET请求合并，并且路由变量是优先的

controller代码

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代码：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: '编辑',            shade: 0.3,            area: ['480px', '440px'],            content: '/index.php/index/edit?id='+id        });    }</script>

2、POST 请求

controller代码

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']);    }}

view代码：edit.html

<!DOCTYPE html><html><head>    <title></title>    <link rel="stylesheet" type="text/css" href="/static/layui/css/layui.css">    <script type="text/javascript" src="/static/layui/layui.js"></script></head><body style="padding:10px;">    <form class="layui-form">        <input type="hidden" name="id" value="{$shop.id}">        <div class="layui-form-item">            <label class="layui-form-label">标题</label>            <div class="layui-input-inline">                <input type="text" class="layui-input" name="title" value="{$shop.title}">            </div>        </div>        <div class="layui-form-item">            <label class="layui-form-label">分类</label>            <div class="layui-input-inline">                <select name="cat">                    <option value=0 {if $shop['cat']==0} selected {/if}></option>                    {volist name="cat" id="cat_v"}                        <option value="{$cat_v['id']}" {if $shop['cat']==$cat_v['id']} selected {/if}>{$cat_v['name']}</option>                    {/volist}                </select>            </div>        </div>        <div class="layui-form-item">            <label class="layui-form-label">原价</label>            <div class="layui-input-inline">                <input type="text" class="layui-input" name="price" value="{$shop.price}">            </div>        </div>        <div class="layui-form-item">            <label class="layui-form-label">折扣</label>            <div class="layui-input-inline">                <input type="text" class="layui-input" name="discount" value="{$shop.discount}">            </div>        </div>        <div class="layui-form-item">            <label class="layui-form-label">库存</label>            <div class="layui-input-inline">                <input type="text" class="layui-input" name="stock" value="{$shop.stock}">            </div>        </div>        <div class="layui-form-item">            <label class="layui-form-label">状态</label>            <div class="layui-input-inline">                <select name="status">                    <option value="1" {if $shop['status']==1} selected {/if}>开启</option>                    <option value="2" {if $shop['status']==2} selected {/if}>关闭</option>                </select>            </div>        </div>    </form>    <div class="layui-form-item">        <div class="layui-input-block">            <button class="layui-btn" onclick="save()">保存</button>        </div>    </div>    <script type="text/javascript">        layui.use(['layer','form'],function(){            form = layui.form;            layer = layui.layer;            $ = layui.jquery;        });        function save(){            $.post('/index.php/Index/edits',$('form').serialize(),function(res){                if(res.code>0){                    layer.alert(res.msg,{icon:2});                }else{                    layer.msg(res.msg);                    setTimeout(function(){parent.window.location.reload();},1000);                }            },'json');        }    </script></body></html>

3、变量修饰符

七、HTTP头信息

HTTP请求头信息的名称不区分大小写，并且_会自动转换为-

print_r( Request::header() );print_r( Request::header('accept_encoding') );
