Hi,
can anyone help me with this issue? I am unable to download SAP Notes from python with my SCN Id.
I tried several ways to do this, for example:
#!/usr/bin/env python3
# -*- coding: utf-8 -*-
import requests
from requests.auth import HTTPBasicAuth
asapnote = "http://service.sap.com/sap/support/notes/1775242"
username = "S00XXXXXX"
password = "XXXXXXXXX"
r = requests.get(asapnote, auth=HTTPBasicAuth(username, password), allow_redirects=True)
print ("RC: %d" % r.status_code)
print (r.headers['content-type'])
print (r.encoding)
print (r.encoding)
print (r.text)
But I always get the following:
RC: 401
text/html
ISO-8859-1
I am interested in extract 'Symptom' and 'Other tems' sections and build my own database of terms to search quickly.
Is this possible?
Thanks in advance

Thanks to this recipe [1] I've been able to download SAP Notes from SAP.
The code:
#!/usr/bin/env python2
# -*- coding: utf-8 -*-
# File: sapnote.py
import urllib2
import sys
import re
import base64
from urlparse import urlparse
asapnote = "http://service.sap.com/sap/support/notes/1775242"
username = "S00XXXXXXXX"
password = "XXXXXXXXXXX"
req = urllib2.Request(asapnote)
try:
handle = urllib2.urlopen(req)
except IOError, e:
pass # here we *want* to fail
else:
# If we don't fail then the page isn't protected
print "This page isn't protected by authentication."
sys.exit(1)
if not hasattr(e, 'code') or e.code != 401:
# we got an error - but not a 401 error
print "This page isn't protected by authentication."
print 'But we failed for another reason.'
sys.exit(1)
authline = e.headers['www-authenticate']
# this gets the www-authenticate line from the headers
# which has the authentication scheme and realm in it
authobj = re.compile(r'''(?:\s*www-authenticate\s*:)?\s*(\w*)\s+realm=['"]([^'"]+)['"]''', re.IGNORECASE)
# this regular expression is used to extract scheme and realm
matchobj = authobj.match(authline)
if not matchobj:
# if the authline isn't matched by the regular expression
# then something is wrong
print 'The authentication header is badly formed.'
print authline
sys.exit(1)
scheme = matchobj.group(1)
realm = matchobj.group(2)
# here we've extracted the scheme
# and the realm from the header
if scheme.lower() != 'basic':
print 'This example only works with BASIC authentication.'
sys.exit(1)
base64string = base64.encodestring('%s:%s' % (username, password))[:-1]
authheader = "Basic %s" % base64string
req.add_header("Authorization", authheader)
try:
handle = urllib2.urlopen(req)
except IOError, e:
# here we shouldn't fail if the username/password is right
print "It looks like the username or password is wrong."
sys.exit(1)
sapnote = handle.read()
print sapnote
But the html source code is awful:

I do not understand why SAP has to obfuscate the code in this way. Why not serve only html without frames neither server side scripting? What do they have to hide?
So, I am done.

To those interested in this topic, I've started to develop an application which help the SAP Consultants to manage their SAP Notes and share them.
