在练习《python编程 从入门到实践》一书的第17章时，我在调用GitHub的api时总是提示443错误，无论是挂代理还是使用devside car都不能解决问题
import requests
url = 'https://api.githun.com/search/reppositories?q=language:python&sort=stars'
r = requests.get(url)
print('Status Code:', r.status_code)
response_dict = r.json()
print(response_dict.keys())
发生异常: ConnectionError
HTTPSConnectionPool(host='api.githun.com', port=443): Max retries exceeded with url: /search/reppositories?q=language:python&sort=stars (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x000001F03E0C52B0>: Failed to establish a new connection: [WinError 10061] 由于目标计算机积极拒绝，无法连接。'))

File "E:\BaiduNetdiskWorkspace\Python代码集合\书籍\Chapter_17\python_repos.py", line 5, in <module>
r = requests.get(url)
由于其api中需要传入参数不一致，需要headers,有的需要token，对于topics可以用如下方式获取：
import requests
url = 'https://api.github.com/search/topics?q=python&sort=stars'
headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/98.0.4758.80 Safari/537.36 Edg/98.0.1108.43', 'content-type': 'application/json; charset=utf-8'}
r = requests.get(url,headers=headers)
print('Status Code:', r.status_code)
response_dict = r.json()
print(response_dict)
如有帮助，请点采纳。
