python之yaml文件读取封装

import os
import yaml
from yamlinclude import YamlIncludeConstructor

YamlIncludeConstructor.add_to_loader_class(loader_class=yaml.FullLoader)   # 用于yaml文件嵌套

PATH = lambda p: os.path.abspath(os.path.join(
    os.path.dirname(__file__), p
))

class YamlData:
    def __init__(self, file):
        if os.path.isfile(PATH(file)):
            self.file = PATH(file)
        else:
            raise FileNotFoundError("文件不存在")

    @property  # 设置属性，调用data方法时可通过调用属性，不需要带括号
    def data(self):
        with open(file=self.file, mode="rb") as f:
            infos = yaml.load(f, Loader=yaml.FullLoader)
            # infos = yaml.load(f)
        return infos

调用操作

infos = YamlData("htmls/loginsucess.yaml").data
print(infos)
