前提：已经安装好了python，还有requests，详见1、pycharm、python下载与安装

import requests

class TestCase:
    def test1(self):
        url = '**这里是接口的url地址**'
        params = {"type": "json"}
        resp = requests.get(url=url, params=params)
        print(resp.json())


if __name__ == '__main__':
    TestCase().test1()

备注：没有接口怎么办？我是从这个网站上copy的https://api.shanhe.kim/
