Swatch Bharat Urban Crawler

This is a crawler that crawls the complete website https://sbmurban.org/rrr-centers and extracts the complete information.

About

  • This crawler was build as a task for ATLAN.
  • The complete data from the website was crawled and stored in a single file
  • This was a new task and learned how to scrap the ASP.NET websites which use __VIEWSTATE (Used the https://blog.scrapinghub.com/2016/04/20/scrapy-tips-from-the-pros-april-2016-edition as a tutorial on how to Crawl ASP.NET websites).
  • Also at the end of complete data scrapping, a POST request would be made to the URL specified.
  • Also, the setup.py file has been added.
  • The extracted file contains the following columns:-
    • State
    • District
    • ULB Name
    • Ward
    • No. of Applications Received
    • No. of Applications Not Verified
    • No. of Applications Verified
    • No. of Applications Approved
    • No. of Applications Approved having Aadhar No.
    • No. of Applications Rejected
    • No. of Applications Pullback
    • No. of Applications Closed
    • No. of Constructed Toilet Photo
    • No. of Commenced Toilet Photo
    • No. of Constructed Toilet Photo through Swachhalaya

Doubts/Assumptions

  1. DOUBT=> How can we make a POST request every 5 minutes, since the data crawling itself takes a lot more of time.

ASSUMPTION=> For making the post request every 5 minutes, we can put the project in the ScrapingHub, and schedule it to crawl every 5 minutes. The crawler has been made such that it would make a POST request on completing the crawling, and the data would automatically be posted.

  1. DOUBT=> How many output files are required? Like 1 file containing all the information. Or the 4 Files containing information for 4 different levels like State, District, ULB and Ward Level.

ASSUMTIONS=> I have made 1 CSV file only whose table was shown in the task containing all the information. Since all other information can be easily extracted from that file.
