Python pandas datareader no longer works for yahoo-finance changed url

Since yahoo discontinued their API support pandas datareader now fails

import pandas_datareader.data as web
import datetime
start = datetime.datetime(2016, 1, 1)
end = datetime.datetime(2017, 5, 17)
web.DataReader('GOOGL', 'yahoo', start, end)

HTTPError: HTTP Error 401: Unauthorized

is there any unofficial library allowing us to temporarily work around the problem? Anything on Quandl maybe?

So they've changed their url and now use cookies protection (and possibly javascript) so I fixed my own problem using dryscrape, which emulates a browser this is just an FYI as this surely now breaks their terms and conditions... so use at your own risk? I'm looking at Quandl for an alternative EOD price source.

I could not get anywhere with cookie browsing a CookieJar so I ended up using dryscrape to "fake" a user download

import dryscrape
from bs4 import BeautifulSoup
import time
import datetime
import re

#we visit the main page to initialise sessions and cookies
session = dryscrape.Session()
session.set_attribute('auto_load_images', False)
session.set_header('User-agent', 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.95     Safari/537.36')    

#call this once as it is slow(er) and then you can do multiple download, though there seems to be a limit after which you have to reinitialise...
session.visit("https://finance.yahoo.com/quote/AAPL/history?p=AAPL")
response = session.body()


#get the dowload link
soup = BeautifulSoup(response, 'lxml')
for taga in soup.findAll('a'):
    if taga.has_attr('download'):
        url_download = taga['href']
print(url_download)

#now replace the default end date end start date that yahoo provides
s = "2017-02-18"
period1 = '%.0f' % time.mktime(datetime.datetime.strptime(s, "%Y-%m-%d").timetuple())
e = "2017-05-18"
period2 = '%.0f' % time.mktime(datetime.datetime.strptime(e, "%Y-%m-%d").timetuple())

#now we replace the period download by our dates, please feel free to improve, I suck at regex
m = re.search('period1=(.+?)&', url_download)
if m:
    to_replace = m.group(m.lastindex)
    url_download = url_download.replace(to_replace, period1)        
m = re.search('period2=(.+?)&', url_download)
if m:
    to_replace = m.group(m.lastindex)
    url_download = url_download.replace(to_replace, period2)

#and now viti and get body and you have your csv
session.visit(url_download)
csv_data = session.body()

#and finally if you want to get a dataframe from it
import sys
if sys.version_info[0] < 3: 
    from StringIO import StringIO
else:
    from io import StringIO

import pandas as pd
df = pd.read_csv(StringIO(csv_data), index_col=[0], parse_dates=True)
df
