Getting Started Spidering a Site

See more Spider Examples

This is a very simple "getting started" example for spidering a web site. As you'll see in future examples, the Chilkat Spider library can be used to crawl the Web. For now, we'll concentrate on spidering a single site. Chilkat2-Python

import chilkat2

success = False

spider = chilkat2.Spider()

# The spider object crawls a single web site at a time.  As you'll see
# in later examples, you can collect outbound links and use them to 
# crawl the web.  For now, we'll simply spider 10 pages of chilkatsoft.com
spider.Initialize("www.chilkatsoft.com")

# Add the 1st URL:
spider.AddUnspidered("http://www.chilkatsoft.com/")

# Begin crawling the site by calling CrawlNext repeatedly.

for i in range(0,10):

    success = spider.CrawlNext()
    if (success == True):
        # Show the URL of the page just spidered.
        print(spider.LastUrl)
        # The HTML is available in the LastHtml property
    else:
        # Did we get an error or are there no more URLs to crawl?
        if (spider.NumUnspidered == 0):
            print("No more URLs to spider")
        else:
            print(spider.LastErrorText)

    # Sleep 1 second before spidering the next URL.
    spider.SleepMs(1000)
