pip install requests

1. target: The page name you want to crawl.
2. since: The date you want to start the crawling.
3. until: The date you want to finish the crawling.

And two additional parameters:

1. -r, --reactions: Default is no. Set to yes will collect reactions data. Because the number of reactions is too large, use it CAREFULLY!!!
2. -s, --stream: Default is no. Set to yes will turn to streaming mode.
