如何在Python中使用HTTP & HTTPS proxy以及带有请求包的OAuth2？

 proxies = {

     'http': 'http://proxy_ip:proxy_port',

     'https': 'http://proxy_ip:proxy_port'

 }

 response = requests.get('http://example.com', proxies=proxies)

 ```

 proxies = {

     'http': 'http://proxy_ip:proxy_port',

     'https': 'http://proxy_ip:proxy_port'

 }

 session = requests.Session()

 session.verify = False

 session.proxies = proxies

 response = session.get('https://example.com')

 ```

 client_id = 'your_client_id'

 client_secret = 'your_client_secret'

 redirect_uri = 'your_redirect_uri'

 authorization_base_url = 'https://example.com/oauth/authorize'

 token_url = 'https://example.com/oauth/token'

 oauth = OAuth2Session(client_id, redirect_uri=redirect_uri)

 authorization_url, state = oauth.authorization_url(authorization_base_url)

 # 用户在浏览器中登录并授权后，会被重定向到redirect_uri，并附带授权码

 authorization_code = 'your_authorization_code'

 token = oauth.fetch_token(token_url, authorization_response=authorization_code, client_secret=client_secret)

 # 使用OAuth2认证后的token发送请求

 response = oauth.get('https://api.example.com/data')

 ```
