curd saveOrderApi 取不到${page}等内置变量

[cybexr]

描述问题：

crud 的saveOrderApi 中，取不到 $page 等crud的

                "type": "crud",
                "name": "detailCRUD",
                "data": {
                    "dict_id": "${dict_id}", "dict_name": "${dict_name}", 
                    "page": "${page}", "perPage": "${perPage}"},

                "saveOrderApi": {
                    "method": "post",
                    "url": "/api/v1/save_abdictitem_order",
                    "data": {
                        "ids": "${ids}",
                        "test": "abc",
                        "dict_id": "${dict_id}",
                        "page": "${page}",
                        "perPage": "${perPage}"
                    },
                    "requestAdaptor": "console.log(context); return { ...api, data: { ...api.data, foo: 'bar' } }; "                   
                },

排序后提交 发送到后端的body
{"ids":"2,1,3,4,5,6,7,8,11,12","test":"abc","dict_id":"","page":"","perPage":"","foo":"bar"}

这是 console中的 context
