thinkphp5 转义不了啊........速救

Answer 1

goods_standard: 是哪取出来的，出现这样的问题，主要是goods_standard这个字段里的数据，本来就是json格式的，你用json_encode 再转变一就这样了，你可以运行一下以下代码，看看是data字段是不是和你的结果很像

<?php
$data = json_encode(['data'=>'大','data1'=>'小']);
$arr = ['name'=>'papersnake','age'=>'35','data'=>$data];
echo(json_encode($arr));
?>

解决方案也有两种，
1： 在服务端把goods_standard json_decode 一下转为对象
2：也可以直接放送这样的JSON到客户端，客户端用JSON.parse() 进行转换
