Adding query parameters to a URL
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I'm trying to automate data download from a website. I need to pass dynamic parameters to the site that changes daily. The html is structured in a table rather than forms. How do I pass my parameters and get a result from the url?
This is what I tried and it needs to be in python 2.7
import urllib
url = "https://disc.gsfc.nasa.gov/SSW/#keywords="
params = urllib.urlencode({'keyword':"(GPM_3IMERGHHE)", 't1':"2019-01-02", 't2':"2019-01-03", 'bboxBbox':"3.52,32.34,16.88,42.89"})
r = urllib.urlopen(url, params)
return = r.read()
python python-2.7 url web-scraping urllib
