编辑响应 JSON Python

Question

无论如何在json django中编辑响应？我正在使用视图视图集

{
  "title": "Cloister",
  "number": 2,
  "summary": "Erasmas describes several buildings of the Concent, namely the Scriptiorium...",
  "page_count": 14
},

例如：首先我得到像这样的 json 返回："标题"："回廊"，我想在 get 字符串后添加一些东西，最终结果必须是："title"："回廊+这里的东西"！

我的任务是获取产品名称，并检查名称是否>40个字符，然后只需40个字符并加上"..."40 个字符后

见下文：

jsonres={
   "title": "Cloister",
   "number": 2,
   "summary": "Erasmas describes several buildings of the Concent, namely the Scriptiorium...",
   "page_count": 14
 }
title=jsonres.get("title")
jsonres["title"]=title + "somethinghere!" #to add something to title
if len(title) > 40:
   jsonres["title"]=title.replace(title[40:],"...") # to truncate 40 + characters and replace
