tp5 post接到的json被轉義怎么解決？？？

　　　　$data =input('post.');//用戶唯一標識$goods = $data['goods'];
        $shopcuxiao=$data['shopcuxiao'];

        $goods=htmlspecialchars_decode($goods);
        $goodslist=html_entity_decode($goods);
        $goodslist=    json_decode($goodslist,true);

 

接收到的$goods是被轉義成

[{"img":"upload/pinpai/img/20180930/60f3860ffe198c67e745b873dd884bbd.jpg","shopPrice":"22","goodsName":"22","ptnum":null},{"img":"upload/pinpai/img/20180930/be60908972d5cc964dfb2acc7a25cf73.jpg","shopPrice":"11","goodsName":"11","ptnum":null}]

可以用函數htmlspecialchars_decode和html_entity_decode進行轉義，這樣可以得到正確的json數據
