ThinkPHP6 请求

thinkphp 飞翔的mouse 50浏览
  • 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"}

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

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

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>
