Using the close() method. Using the quit() method.
1 Answer. Show activity on this post. using stream = True sets the stage for you to read the response data in chunks as opposed to having the entire response body downloaded in one go upfront.
We specify the stream = True in the request get method. This allows us to control when the body of the binary response is downloaded.
Response. Close() closes the socket connection to a client.
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'})
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
As discussed here, there really isn't such a thing as an HTTP connection and what httplib refers to as the HTTPConnection is really the underlying TCP connection which doesn't really know much about your requests at all. Requests abstracts that away and you won't ever see it.
The newest version of Requests does in fact keep the TCP connection alive after your request.. If you do want your TCP connections to close, you can just configure the requests to not use keep-alive.
s = requests.session()
s.config['keep_alive'] = False
please use response.close()
to close to avoid "too many open files" error
for example:
r = requests.post("https://stream.twitter.com/1/statuses/filter.json", data={'track':toTrack}, auth=('username', 'passwd'))
....
r.close()
On Requests 1.X, the connection is available on the response object:
r = requests.post("https://stream.twitter.com/1/statuses/filter.json",
data={'track': toTrack}, auth=('username', 'passwd'))
r.connection.close()
