问题 Is there a way to tell the requests lib to add multiple certificates like all .pem files from a specified folder? import requests, glob CERTIFICATES = glob('/certs/') url = '127.0.0.1:8080' requests.get(url, cert=CERTIFICATES) Seems to work only for a single certificate I already search google and the python doc.

问题 Hi not every time but sometimes when trying to gain access to the LSE code I am thrown the every annoying HTTP Error 403: Forbidden message. Anyone know how I can overcome this issue only using standard python modules (so sadly no beautiful soup). import urllib.request url = "http://www.londonstockexchange.com/exchange/prices-and-markets/stocks/indices/ftse-indices.html" infile = urllib.request.urlopen(url) # Open the URL data = infile.read().decode('ISO-8859-1') # Read the content as string
