我这里有一个接口，是添加购物车的。商品有属性，例如颜色 尺码 我提交参数的时候会提示选择规格。。不知道是不是提交的格式不对。请求帮助
/**
* 加入购物车接口
*
* 输入：
* id:int 商品id
* deal_attr: array 结构如下
* Array
* (
* [属性组ID] => 11 int 属性值ID
* )
* =======新增两个参数============
* @param bool $outputReturn 是否以output返回
* @param array $param 该值不为空，则加入购物车的id,attr以此为准，否则取$_REQUEST
* @param
*$param = Array
* (
[id] => 商品id int
* [attr] => Array(
[属性组ID] => 11 int 属性值ID
)
* )
* =======//新增两个参数============ *
*
* 输出：
* status: int 状态 0错误 1加入成功 -1未登录需要登录
* info: string 状态为1时该值为空，否则为出错的提示

我提交的参数 url/index.php?c=cart&a=addcart&id=88&deal_attr=[{19:357},{20:359}]
但是提交后台会返回“请选择商品规格”，一头雾水，我应该提交怎样的参数结构
