python-requests 必需如下使用才能保持keep-alive

import requestssession = requests.session()session.get('http://www.qq.com')session.get('http://www.qq.com')#输出如下>>INFO:requests.packages.urllib3.connectionpool:Starting new HTTP connection (1): www.qq.com>>DEBUG:requests.packages.urllib3.connectionpool:"GET / HTTP/1.1" 200 None>>DEBUG:requests.packages.urllib3.connectionpool:"GET / HTTP/1.1" 200 None

其官网提供的调试的方法是会产生新连接的，可以通过以下方法设置log为debug看到：

logging.BASIC_FORMAT = '%%(levelname)s - %(filename)s[%(lineno)d]- %(message)s'logging.basicConfig() # you need to initialize logging, otherwise you will not see anything from requestsrequests_log = logging.getLogger("requests.packages.urllib3")requests_log.setLevel(logging.DEBUG)requests_log.propagate = True# 第一次调用，log会输出创建一个新连接并放进连接池requests.get('http://www.qq.com')# 第二次调用，log依然输出创建一个新连接并放进连接池requests.get('http://www.qq.com')#输出如下：>>INFO:requests.packages.urllib3.connectionpool:Starting new HTTP connection (1): www.qq.com>>DEBUG:requests.packages.urllib3.connectionpool:"GET / HTTP/1.1" 200 None>>INFO:requests.packages.urllib3.connectionpool:Starting new HTTP connection (1): www.qq.com>>DEBUG:requests.packages.urllib3.connectionpool:"GET / HTTP/1.1" 200 None
