Yaml如何做动态参数化

话不多说，直接上代码：

data.yaml

data222: {{rand_str()}}

demo.py

import os
import jinja2
import yaml
from faker import Faker


def render(tpl_path, **kwargs):
    path, filename = os.path.split(tpl_path)
    return jinja2.Environment(loader=jinja2.FileSystemLoader(path or './')
    ).get_template(filename).render(**kwargs)


# yaml 文件调用以下函数
def rand_str():
    faker = Faker("zh_CN")
    return str(faker.phone_number()) #生成随机的手机号码


if __name__ == '__main__':
    r = render("data.yaml", **{"rand_str": rand_str})
    print(r)
    print(yaml.safe_load(r))

 运行结果：

data222: 18966216278
{'data222': 18966216278}
