ThinkPHP6 请求

794次阅读

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: '添加', 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="0" {if $shop['status']==0} 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>

二、请求类型

方法	说明
method	获取当前请求类型
has	判断传值是否存在
isGet	判断是否 GET 请求
isPost	判断是否 POST 请求
isPut	判断是否 PUT 请求
isDelete	判断是否 DELETE 请求

1、method

public function edit(){ if(Request::method() == 'POST'){ // print_r(Request::method());exit; $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']); } }else{ // print_r(Request::method());exit; $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(); } }

三、增加数据

controller 代码

public function add(){ if(Request::method() == 'POST'){ $all = Request::param(); $insert = Db::table('shop_goods')->insert($all); if($insert){ echo json_encode(['code'=>0,'msg'=>'添加成功']); }else{ echo json_encode(['code'=>1,'msg'=>'添加失败']); } }else{ $cat = Db::table('shop_cat')->where('status',1)->select(); View::assign([ 'cat' => $cat ]); return View::fetch(); } }

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"> <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=""> </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 selected></option> {volist name="cat" id="cat_v"} <option value="{$cat_v['id']}">{$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=""> </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=""> </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=""> </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" selected> 开启 </option> <option value="0"> 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(){ $.post('/index.php/Index/add',$('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>

四、删除数据

controller 代码

public function del(){ $id = Request::param('id'); $delete = Db::table('shop_goods')->where('id',$id)->delete(); if($delete){ echo json_encode(['code'=>0,'msg'=>'删除成功']); }else{ echo json_encode(['code'=>1,'msg'=>'删除失败']); } }

view 代码：edit.html

<button class="layui-btn layui-btn-danger layui-btn-xs" onclick="del({$right_v.id})">删除</button> <script type="text/javascript"> function del(id){ layer.confirm('确定要删除吗？', { icon:3, btn: ['确定','取消'] }, function(){ $.post('/index.php/index/del',{'id':id},function(res){ if(res.code>0){ layer.alert(res.msg,{icon:2}); }else{ layer.msg(res.msg); setTimeout(function(){window.location.reload();},1000); } },'json'); }); } </script>
