Python使用requests時遇到Failed to establish a new connection
作者:互联网
再寫Zeppelin的CLI工具的時候

遇到了開起太多connection這樣一個錯誤
requests.exceptions.ConnectionError: HTTPConnectionPool(host='xxxxx', port=xxxxx): Max retries exceeded with url: /api/notebook/2BG5CTGN7/paragraph/20160407-173136_827952200 (Caused by NewConnectionError('<requests.packages.urllib3.connection.HTTPConnection object at 0x29b44d0>: Failed to establish a new connection: [Errno 99] Cannot assign requested address',))
細查了一下原因出在我是用Python的requests套件去送HTTP Request
原本我一直以為下面這種寫法不會占用到太多connection資源
requests.post("http....") requests.get("http....")
但是程式邏輯的關係我會在短時間使用多次requests.post
其結果就是跳出了Failed to establish a new connection
這樣一個錯誤
google一下之後,一個根本的解決方法是在發起一個http request之後設定header將其關閉
修改如下
requests..get("http://...", headers={'Connection':'close'}) requests..post("http://...", headers={'Connection':'close'})
這邊做個筆記
