简单使用-从.yaml文件中加载配置并返回一个对应的字典

import yaml

class Config:
    _instance = None

    def __new__(cls):

        env = os.getenv('ENV', 'dev')
        with open(f"{cur_path}/../common/config/{env}/config.yaml", "r", encoding="UTF-8") as f_config:

                # 读取配置文件
                _config = yaml.load(f_config, Loader=yaml.SafeLoader)

if __name__ == "__main__":
    print(CONFIG)
    print(type(CONFIG))
