wx.request({

    url:url,

    data: {

        action: action,

        param: param,

        Id: Id,

        small:{

            a:'1',

            b:'2',

            c:'3'

       }

    }

});

我是这样子传的，但是服务器那边收到的是这样的形式

Array

(

    [action] => action

    [param] => param

    [Id] => Id

    [small] => {\"a\":\"1\",\"b\":\"2\",\"c\":\"3\"}

)

我想要的是这种形式，请问应该怎么传？

Array

(

    [action] => action

    [param] => param

    [Id] => Id

    [small] => Array(

                        [a]=>1

                        [b]=>2

                        [c]=>3

                    )

)
