Python-Requests close http connection
I came to this question looking to solve the "too many open files" error
, but I am using requests.session()
in my code. A few searches later and I came up with an answer on the Python Requests Documentation which suggests to use the with
block so that the session is closed even if there are unhandled exceptions:
with requests.Session() as s:
s.get('http://google.com')
If you're not using Session you can actually do the same thing: https://2.python-requests.org/en/master/user/advanced/#session-objects
with requests.get('http://httpbin.org/get', stream=True) as r:
# Do something
I think a more reliable way of closing a connection is to tell the sever explicitly to close it in a way compliant with HTTP specification:
HTTP/1.1 defines the "close" connection option for the sender to signal that the connection will be closed after completion of the response. For example,
Connection: close
in either the request or the response header fields indicates that the connection SHOULD NOT be considered `persistent' (section 8.1) after the current request/response is complete.
The Connection: close
header is added to the actual request:
r = requests.post(url=url, data=body, headers={'Connection':'close'})
