In [2]: import requests

In [3]: s = requests.Session()

In [4]: s.headers

如果你是爬虫相关的业务？抓取的网站还各种各样，每个服务器的地址都不一样，那么你不适用于我上面的方法,而是需要把Connection给关闭.
当然还是看场景. 多方调试下.

r = requests.post(url=url,
data=body, headers={‘Connection’:'close’})

headers = {'Content-Type': 'application/json','Connection':'keep-alive'}

        r = client.post(SIGMENT_ADDRESS, data=json.dumps(text_list), headers=headers)
