Get the Last-Modified Date Before HTTP Download

See more HTTP Examples

Demonstrates how to send a HEAD request to get the last-modified date of a file on a web server (without downloading the file). CkPython

import sys
import chilkat

success = False

# This example assumes the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

http = chilkat.CkHttp()

resp = chilkat.CkHttpResponse()
success = http.HttpNoBody("HEAD","https://www.chilkatsoft.com/hamlet.xml",resp)
if (success == False):
    print(http.lastErrorText())
    sys.exit()

# Examine the response header.
print(resp.header())

# Here is a sample response header:

# 	Content-Length: 279658
# 	Content-Type: text/xml
# 	Last-Modified: Thu, 12 May 2016 15:14:08 GMT
# 	Accept-Ranges: bytes
# 	ETag: "c1cd8bee60acd11:0"
# 	Server: Microsoft-IIS/8.5
# 	X-Powered-By: ASP.NET
# 	X-Powered-By-Plesk: PleskWin
# 	Date: Thu, 25 Jul 2019 16:40:54 GMT

# Get the Last-Modified header.
lastModStr = resp.getHeaderField("Last-Modified")
# If the header exists...
if (resp.get_LastMethodSuccess() == True):
    # Parse the RFC822 format date/time string
    ckdt = chilkat.CkDateTime()
    ckdt.SetFromRfc822(lastModStr)

    # If we want to access individual date/time parts (in the local timezone)
    dt = chilkat.CkDtObj()
    ckdt.ToDtObj(True,dt)

    print("day/month/year = " + str(dt.get_Day()) + "/" + str(dt.get_Month()) + "/" + str(dt.get_Year()))
