如果需要使用代理，你可以通过为任意请求方法提供proxies参数来配置单个请求：
import requests# 根据协议类型，选择不同的代理proxies = {"http": "http://12.34.56.79:9527","https": "http://12.34.56.79:9527",}response = requests.get("", proxies = proxies)print response.text
也可以通过本地环境变量HTTP_PROXY和HTTPS_PROXY来配置代理：
export HTTP_PROXY="http://12.34.56.79:9527"export HTTPS_PROXY="https://12.34.56.79:9527"
