Python-Requests close http connection

Question

I was wondering  how do you close a connection with Requests  python-requests org   With httplib it s HTTPConnection close    but how do I do the same with Requests  Code  r   requests post  quot https   stream twitter com 1 statuses filter json quot   data   track  toTrack   auth   username    passwd    for line in r iter lines        if line          self mongo  db   tweets insert json loads line

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'})

To remove the  keep-alive  header in requests  I just created it from the Request object and then send it with Session  headers      Host     1 2 3 4    User-Agent     Test client  x86 64-pc-linux-gnu 7 16 3     Accept            Accept-Encoding     deflate  gzip    Accept-Language     it IT     url    https   stream twitter com 1 statuses filter json   r   requests get url  headers   headers   this triggers keep-alive  True s   requests Session   r   requests Request  GET   url  headers

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

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

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
