The default port for the HTTPS protocol (always 443). The default port for the HTTP protocol (always 80). The constants defined in this module are: http.client. New in version 3.5: Previously, BadStatusLine ('') was raised.

The following exceptions are raised as appropriate: exception http.client. Read these field lines, so the first line should already be consumed Parse_headers() does not parse the start-line of a HTTP message

The optional blocksize parameter sets the buffer size in bytes forįor example, the following calls all create instances that connect to the server To use as the source address the HTTP connection is made from. The optional source_address parameter may be a tuple of a (host, port) (if it is not given, the global default timeout setting is used). Operations (like connection attempts) will timeout after that many seconds If the optional timeout parameter is given, blocking String if it has the form host:port, else the default HTTP port (80) is If no port number is passed, the port is extracted from the host It should be instantiated passing it a host and optional port HTTPConnection ( host, port=None, source_address=None, blocksize=8192 ) ¶Īn HTTPConnection instance represents one transaction with an HTTP The module provides the following classes: class http.client. from ftplib import FTPįtp.retrbinary('RETR ' + filename, localfile.write, 1024)įtp.HTTPS support is only available if Python was compiled with SSL support Send a QUIT command to the server and close the connection.įollowing example establishes anonymous connection with a server, downloads a file to local folder and uploads a local file. Note that the SIZE command is not standardized, but is supported by many common server implementations. On success, the size of the file is returned as an integer, otherwise None is returned. Request the size of the file named filename on the server. Remove the directory named dirname on the server. Return the pathname of the current directory on the server. mkd(pathname)Ĭreate a new directory on the server. Remove the file named filename from the server. Produce a directory listing as returned by the LIST command, printing it to standard output. fp is a file object (opened in binary mode) which is read until EOF using its read() method dir() cmd should be an appropriate STOR command: 'STOR filename'. cmd should be an appropriate RETR command: 'RETR filename'. retrbinary(cmd, callback, blocksize=8192, rest=None) If user is 'anonymous', the default passwd is abort()Ībort a file transfer that is in progress. If no user is specified, it defaults to 'anonymous'.

The passwd and acct parameters are optional and default to the empty string. Login(user='anonymous', passwd='', acct='') Return the welcome message sent by the server in reply to the initial connection. The default port number is 21, as specified by the FTP protocol specification. The FTP class supports following methods − connect()Ĭonnect to the given host and port. To establish connection with a FTP server, obtain FTP object. The all important The FTP class in ftplib module implements the client side of the FTP protocol.
