• How to decode an encoded zipfile using Python?

  I have a base64 encoded zip file. I am able to convert that zip file and then extract its content using Windows commandline. I have been trying to do the same with Python, but unsuccessful. Could you please help me? When I run the following code:

  import base64
  import codecs
  import zlib
  import io, zipfile, json, pprint
  
  d = open("data.txt", "rb").read()
  #dd = base64.decodestring(d)
  #print(dd)
  z = zipfile.ZipFile(io.BytesIO(d))
  unpack = zlib.decompress(d)
  

  I get the following error:

  raise BadZipFile("File is not a zip file") zipfile.BadZipFile: File is not a zip file

  The data.txt file contains the base64 string:
• Base64 does not encode the entire string

  When I encode tex, for some reason it cuts off part of the string ... What could be the problem?

          DateFormat dateFormat =
                  new SimpleDateFormat("MM/dd/yyyy HH:mm:ss a", Locale.ENGLISH);
          Date date = new Date();
          Calendar calendar = Calendar.getInstance();
          calendar.setTime(date);
          calendar.add(Calendar.HOUR,+ 9);
          String server_time = dateFormat.format(calendar.getTime());
          String wmsAuthSign = "server_time=" + server_time + "&hash_value=U2QK9TLB55JWTZr3OKZHtg==&validminutes=120";
          wmsAuthSign = "?wmsAuthSign=" + Base64.encodeToString(wmsAuthSign.getBytes(), Base64.DEFAULT);
  

  I am submitting something like this:

  server_time=02/18/2019 23:38:43 PM&hash_value=U2QK9TLB55JWTZr3OKZHtg==&validminutes=120
  

  And if you decode the encoded text, you get a trimmed result:

  server_time=02/18/2019 23:38:43 PM&hash_value=U2QK9TLB55J
  
• How to Convert Base64 string To Video in C#

  I'm trying to convert a base64 string to video In C#, and save it in the App_Data/Video/Film folder . It's not working.

  Code:

  public void ConvertToVideo(string data)
      {
          byte[] ret = Convert.FromBase64String(data);
          string date = DateTime.Now.ToString().Replace(@"/", @"_").Replace(@":", @"_").Replace(@" ", @"_");

• how to use requests raise error in python

  Iam using python to fetch content from some urls. So I have a list of urls, and all are fine except one of them where I get a 404. I wanted to fetch this like:

  for url in urls:
      r = requests.get(url)
  
      try:
          r.raise_for_status()
      except RuntimeError:
          print('error: could not get content from url because of {}'.format(r.status_code))
  

  But now, the exception raised by raise_for_status() is not fetched but just printed out? How can I print my own error code if its raised?
• I would like to calculate an extrema (maximum, minimum) in a given interval but there is a TypeError

  I develop a program which can find roots, extrema etc.... (I use Thonny): "TypeError: 'Integer' object does not support indexing".

  In my program you enter any function and the program calculates the extrema. I use sympy. My code isn't very long so I included everything.

  Thanks for any tips and answers.

  edit:
  Maybe its a little hard to understand my program without an explaination: First the user types in any function. Then he adds an interval (xmin, xmax).
  Using f=S(funk...) I change the typed in function to something sympy can understand. Then sympy calculates the first and second differentiation using diff.

  Using solve sympy calculates the roots from f_diff_1 and puts them in a list.
  There is a loop where sympy calculates y (y_0=f.subs(x, x_0[i])) and afterwards there is an another loop where every x and y is displayed if it is located within the interval.

  from sympy import*
  x=Symbol("x")
  #Funktion eingeben
  Funktion=input("Funktion eingeben: ")
  xmin=float(input("Grenzwert links: "))
  xmax=float(input("Grenzwert rechts: "))
  #eingegebene Funktion für Sympy umwandeln, damit Sympy sie als     Funktion erkennt
  f=S(Funktion)
  #erste und zweite Ableitung
  f_diff_1=diff(f, x)
  f_diff_2=diff(f, x)
  #Extrempunkte bestimmen
  extrema=solve(Eq(f_diff_1, x))
  x_0=extrema
  Anzahl_1=len(x_0)
  for i in range (Anzahl_1):
      y_0=f.subs(x, x_0[i])
  for a in range (Anzahl_1):
      if xmin<=x_0[a] and xmax>=x_0[a]:
          #print(f"Der Hochpunkt liegt bei: ({x_0[a]}| {y_0[a]})")
          print("Extrempunkt liegt bei", x_0[a], y_0[a])
  
• Constructing python request using certificate

  I need to access Splunk from python. My Splunk admin said the user / password authentication is not possible, I have to use the certificate. I would need help to construct my request in python provided I have the certificate of the user (C5271127) in hand. At the moment my code looks as follows:

  import urllib
  import urllib.parse
  import urllib.request as urllibrequest
  import requests
  import re
  from xml.dom import minidom
  
  def pretty_print_POST(req):
      """
      At this point it is completely built and ready
      to be fired; it is "prepared".
  
      However pay attention at the formatting used in 
      this function because it is programmed to be pretty 
      printed and may differ from the actual request.
      """
      print('{}\n{}\n{}\n\n{}'.format(
          '-----------START-----------',
          req.method + ' ' + req.url,
          '\n'.join('{}: {}'.format(k, v) for k, v in req.headers.items()),
          req.body,
      ))
  
  
  base_url = 'https://splunk.mo.sap.corp:8089'
  username = 'C5271127'
  password = 'XXXX'
  search_query = "search=savedsearch BWP_nodes_in_sync"
  
  # encoded = urllib.parse.urlencode(({password}).encode('utf8'))
  # print (urllib.parse.urldecode(password))
  
  # Login and get the session key
  request = urllibrequest.Request(base_url + 
  '/servicesNS/admin/search/auth/login', 
      data = urllib.parse.urlencode({'username': username, 'password': 
  password}).encode("utf-8"))
  
  
  #prepared = request.prepare()
  #pretty_print_POST(request)
  
  
  server_content = urllibrequest.urlopen(request)
  
  session_key = minidom.parseString(server_content.read()).\
          getElementsByTagName('sessionKey')[0].childNodes[0].nodeValue
  print ("Session Key: %s" % session_key) 
  
  # Perform a search
  r = requests.post(base_url + '/services/search/jobs/', data=search_query,
      headers = { 'Authorization': ('Splunk %s' %session_key)},
      verify = False)
  
  print (r.text.split('\n')[1])
  prog = re.compile(r'[^\d]+(\d+\.\d+)[^\d]+')
  id = prog.match(r.text.split('\n')[1]).group(1)
  
  print (base_url + '/services/search/jobs/%s/results' % id)
  r = requests.get(base_url + '/services/search/jobs/%s/results' % id, 
  data="output_mode=csv",
      headers = { 'Authorization': ('Splunk %s' %session_key)},
      verify = False)
  print (r.text)
  

  As mentioned, only the certificate logon is possible, so I get the error:

  RLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify 
  failed (_ssl.c:833)>
  

  I need help with building the request using the certificate. I can extract it from browser for the user C5271127. How the proper code would look like?

  Kind Regards, Kamil
