Python 报错 json.decoder.JSONDecodeError: Expecting property name enclosed in double quotes

测试接口时服务器端出现错误：
json.decoder.JSONDecodeError: Expecting property name enclosed in double quotes: line x column y (char z)
是后端在处理json对象时会将json对象转换为字典再执行其他逻辑，json属性名必须用双引号包裹，所以单纯的用单引号，结果报错
以下是原json

{
  'items': [{'datapack_id':111,'revision_id':222},{'datapack_id':333,'revision_id':444}],
  'confirm': true
}

更改后正确的json

{
  "items": [{"datapack_id":111,"revision_id":222},{"datapack_id":333,"revision_id":444}],
  "confirm": true
}
