yaml相关方法封装

读取指定yaml文件数据

import yaml
import sys,os
add_path = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
sys.path.append(add_path)
path = os.path.dirname(__file__)
yaml_path =path + '/xxxx.yaml'


def read_file_data_yaml(yaml_path,hierarchy=None):
    '''
    :param yaml_path: 打开的yaml文件夹路径
    :param hierarchy: 二级层级,没有则打开一级路径数据
    :return:
    '''
    with open(yaml_path,'rb') as f :# 传入文件路径
        config = yaml.load(stream=f, Loader=yaml.FullLoader)
        if hierarchy:
            yaml_data = config[hierarchy]
        else:
            yaml_data = config
        return yaml_data
