重新映射dict
dictremapper的Python项目详细描述
dictremapper正在重新映射dict库
- 已订购（重要）
- 支持继承（映射器）
- 支持嵌套结构
- （不包括每个层的选项）
简单示例
importrequestsimportjsonfromdictremapperimportRemapper,PathclassSummaryRemapper(Remapper):fullname=Path("full_name")url=Path("html_url")description=Path("description")url="https://api.github.com/repos/podhmo/dictremapper"data=requests.get(url).json()data=SummaryRemapper()(data)print(json.dumps(data,indent=2))
输出
{
"fullname": "podhmo/dictremapper",
"url": "https://github.com/podhmo/dictremapper",
"description": "remapping dict"
}
支持继承（映射器）
fromdictremapperimportRemapper,PathclassURLRemapper(Remapper):url=Path("html_url")classDescriptionRemapper(Remapper):fullname=Path("full_name")description=Path("description")classSummaryRemapper(URLRemapper,DescriptionRemapper):star=Path("stargazers_count")url="https://api.github.com/repos/podhmo/dictremapper"data=requests.get(url).json()remapped=SummaryRemapper()(data)print(json.dumps(remapped,indent=2))
输出
{
"url": "https://github.com/podhmo/dictremapper",
"fullname": "podhmo/dictremapper",
"description": "remapping dict",
"star": 0
}
如果你想换订单的话。ChangeOrder也许有帮助。
fromdictremapperimportChangeOrderclassSummaryRemapper2(URLRemapper,DescriptionRemapper):url=ChangeOrder(URLRemapper.url)description=ChangeOrder(DescriptionRemapper.description)star=Path("stargazers_count")remapped=SummaryRemapper2()(data)print(json.dumps(remapped,indent=2))
输出
{
"fullname": "podhmo/dictremapper",
"url": "https://github.com/podhmo/dictremapper",
"description": "remapping dict",
"star": 0
}
支持嵌套结构
classMyMapper3(Remapper):body=Path("body",callback=MyMapper())children=Path("children",callback=MyMapper2(many=True))
排除每个层的选项
classMyMapper3(Remapper):body=Path("body",callback=MyMapper())children=Path("children",callback=MyMapper2(many=True,excludes=["object.name","object.age","id"]))MyMapper3(excludes=["children.object.description","body"])(d)
