help request: how to rewrite upstream response

[yunduansing]

Description

1.upstream body may response:
{ "data": [], "total": 100 }
http status code: 200

then I want to rewrite it like :
{ "data":{ "data": [],"total": 100} , "errcode": 0 }
http status code: 200

2.upstream body may response:
"Internal error."
http status code: 500

then I want to rewrite it like :
{ "msg": "Internal error.", "errcode": 500, "data": null }
http status code: 200

I want to know how to do it when I use the default response-rewrite plugin
