Restart/Resume FTP UploadDemonstrates how to restart / resume an FTP upload.
import sys import chilkat ftp = chilkat.CkFtp2() # Any string unlocks the component for the 1st 30-days. success = ftp.UnlockComponent("Anything for 30-day trial") if (success != True): print ftp.lastErrorText() sys.exit() ftp.put_Hostname("ftp.chilkatsoft.com") ftp.put_Username("****") ftp.put_Password("****") # Connect and login to the FTP server. success = ftp.Connect() if (success != True): print ftp.lastErrorText() sys.exit() # Change to the remote directory where the file will be uploaded. success = ftp.ChangeRemoteDir("temp") if (success != True): print ftp.lastErrorText() sys.exit() # In this example, assume that a previous FTP upload failed, # and the incomplete file (bigFile.zip) exists on the FTP server. # You only need to set the RestartNext property to resume # the upload. When RestartNext is set, the next call # to PutFile (or PutFileFromBinaryData, PutFileFromTextData) # will automatically resume the upload from the point of failure. # (The way it works is that the FTP component sends a "SIZE" # command to the FTP server to find out how many bytes of # the file already exist on the server. It then begins # uploading from that point. # Note: After PutFile is called, the RestartNext property # is automatically set to false. ftp.put_RestartNext(True) # Upload a file with restart. localFilename = "bigFile.zip" remoteFilename = "bigFile.zip" success = ftp.PutFile(localFilename,remoteFilename) if (success != True): print ftp.lastErrorText() sys.exit() ftp.Disconnect() print "File Uploaded!" |
