- selenium Python package
work on site map first, wrote the web scrape script
4/1/2019
Site map:
- Some href may not include home_page url : e.g. /careers
- Updated urlcrawler.py (having issues with identifying internal links does not start with "/") <- will work on this part tomorrow
4/2/2019
Site map:
- Solved the second bullet point from yesterday
- Recursion to get internal links from a page causing HTTPerror on some websites (should set up a depth constraint- WILL WORK ON THIS TOMORROW )
4/3/2019
Site map:
- Find similar work done for mcnair project
- Clean up my own code + figure out the depth constraint
4/4/2019
Site map (BFS approach is DONE):
- Test run couple sites to see if there are edge cases that I missed
- Implement the BFS code: try to output the result in a txt file
- Will work on DFS approach next week
4/8/2019
Site map:
- Work on DFS approach (stuck on the anchor tag, will work on this part tomorrow)
- Suggestion: may be able to improve the performance by using queue
4/9/2019
- Something went wrong with my DFS algorithm (keep outputting None as result), will continue working on this tomorrow
4/10/2019
- Finished DFS method
- Compare two methods: DFS is 2 - 6 seconds faster, theoretically, both methods should take O(n)
- Test run several websites
4/11/2019 Screenshot tool:
- Selenium package reference of using selenium package to generate full page screenshot
http://seleniumpythonqa.blogspot.com/2015/08/generate-full-page-screenshot-in-chrome.html
- Set up the script that can capture the partial screen shot of a website, will work on how to get a full screen shot of a website next week
- Downloaded the Chromedriver for Win32
