18.7.1 HTTPConnection Objects


18.7.1 HTTPConnection Objects

HTTPConnection instances have the following methods:

request( method, url[, body[, headers]])
This will send a request to the server using the HTTP request method method and the selector url. If the body argument is present, it should be a string of data to send after the headers are finished. The header Content-Length is automatically set to the correct value. The headers argument should be a mapping of extra HTTP headers to send with the request.

getresponse( )
Should be called after a request is sent to get the response from the server. Returns an HTTPResponse instance. Note: Note that you must have read the whole response before you can send a new request to the server.

set_debuglevel( level)
Set the debugging level (the amount of debugging output printed). The default debug level is 0, meaning no debugging output is printed.

connect( )
Connect to the server specified when the object was created.

close( )
Close the connection to the server.

As an alternative to using the request() method described above, you can also send your request step by step, by using the four functions below.

putrequest( request, selector[, skip_host[, skip_accept_encoding]])
This should be the first call after the connection to the server has been made. It sends a line to the server consisting of the request string, the selector string, and the HTTP version (HTTP/1.1). To disable automatic sending of Host: or Accept-Encoding: headers (for example to accept additional content encodings), specify skip_host or skip_accept_encoding with non-False values. Changed in version 2.4: skip_accept_encoding argument added.

putheader( header, argument[, ...])
Send an RFC 822-style header to the server. It sends a line to the server consisting of the header, a colon and a space, and the first argument. If more arguments are given, continuation lines are sent, each consisting of a tab and an argument.

endheaders( )
Send a blank line to the server, signalling the end of the headers.

send( data)
Send data to the server. This should be used directly only after the endheaders() method has been called and before getresponse() is called.
