php在谷歌环境下无法获得jq下的ajax传来的post变量 在火狐可以

Question

总是有这个报错
有时候刷新就没了 但后台php依旧无法获取到ajax的变量
用的是iis建站 用的ip访问。

js

   var textarea=$("#textarea_liuyan").val();
    var name2=$("#name2").val();
   $.ajax({
   //请求方式
   type:'POST',
   //发送请求的地址
   url:'http://192.168.0.102:85/php/liuyan.php',
   //服务器返回的数据类型


   data:{
     "name":name2,
     "tel":textarea
     
   },  
   
  success:function(data){
     alert(name2);
     console.log(data);
     console.log(typeof data);
     console.log(XMLHttpRequest);
  },
  error:function(data){
   alert("down");
  
     console.log (data);
     console.log (typeof textarea);
  }
 });
 

php

<?php

header('Access-Control-Allow-Origin:*');
 define('DB_HOST', 'localhost');
 define('DB_USER', 'root');
 define('DB_PASS', '1234');
 define('DB_NAME', 'dengluzhuce');
 $dbc = mysqli_connect(DB_HOST, DB_USER, DB_PASS, DB_NAME);

//$returnData="SELECT * FROM listtop where listTop='listTop4'";
   //echo $_POST['textarea_liuyan1'];
//$sql="SELECT * FROM listtop where listTop='".$listTopNum."'";
//$returnData=mysql_query($sql);
//$textarea_liuyan = $_POST['textarea_liuyan1'];
//$name2 = $_POST['name1'];//ajax中的data参数用同名变量接收

/*查询方法3，POST传参*/


var_dump($_POST['name']);
?>

Answer 1

请求头为 Content-Type: application/json 时，接受请求体需要用 file_get_contents('php://input') 来获取输入值。
