Method Name:
connect
Method Signature:
connect(host=””, port =21, timeout=None, source_address=None)
Parameters:
Host – The IP address or the host name of the FTP server to connect to.
Port – The port number at which the FTP server is listening. The standard port number at which FTP servers listen is 21.
timeout – Number of seconds to block till the connection is made. If timeout seconds are elapsed the connect method returns.
source_address - A tuple consisting of ip address/host name and port number of the client.
Method overview:
- The method connect() establishes a connection to an FTP server with the name/ip address specified by host parameter.
- Since the constructor FTP() as well takes parameters like hostname, user name and so on, it is only required to call this method if a connection was not already established through the FTP constructor.
Example:
|
# Example Python program that uses connect() method of ftplib.FTP class # to connect to an FTP server from ftplib import FTP
# Name of the server serverName = "apublicserverthatallowstesting.com";
# Create an FTP instance ftpObject = FTP();
# Connect to the FTP server ftpResponseCode = ftpObject.connect(host=serverName); print("Response code for connect:%s"%ftpResponseCode)
# Do an anonymous login ftpResponseCode = ftpObject.login(); print("Response code for login:%s"%ftpResponseCode)
# Issue the FTP command LIST to get the information on files present in # the current working directory ftpResponseCode = ftpObject.retrlines("LIST", print); print("Response code for command LIST:%s"%ftpResponseCode); |
