[issue25075] issue from python in encode base64 with Json Model
New submission from Ramin Farajpour Cami:
Hi,
issue from python in encode base64 with Json Model in twice encode with base64
output python different with JAVA and C# , if programmer using rest-service in
server side and other programmer using UI(Python Django) in client site , this
encode different for encode and decode with match json encode model,
real example :
1- go to https://www.base64encode.org/
2- using {"userName":"admin","password":"admin"} (default UTF-8)
3-first encode oupput : "eyJ1c2VyTmFtZSI6ImFkbWluIiwicGFzc3dvcmQiOiJhZG1pbiJ9"
4-again second encode "eyJ1c2VyTmFtZSI6ImFkbWluIiwicGFzc3dvcmQiOiJhZG1pbiJ9"
output :
"ZXlKMWMyVnlUbUZ0WlNJNkltRmtiV2x1SWl3aWNHRnpjM2R2Y21RaU9pSmhaRzFwYmlKOQ=="
now second output python json model :
Microsoft Windows [Version 6.2.9200]
(c) 2012 Microsoft Corporation. All rights reserved.
C:\Users\Matthew F4rr3ll>python
Python 2.7.7 (default, Jun 1 2014, 14:21:57) [MSC v.1500 64 bit (AMD64)] on win
32
Type "help", "copyright", "credits" or "license" for more information.
>>> import json
>>> s1='{"userName":"admin","password":"admin"}'
>>> s2 = s1.encode("base64")
>>> e = s2.encode("base64")
>>> print e
ZXlKMWMyVnlUbUZ0WlNJNkltRmtiV2x1SWl3aWNHRnpjM2R2Y21RaU9pSmhaRzFwYmlKOQo=
>>>
>>>
>>>
now check this output :
ZXlKMWMyVnlUbUZ0WlNJNkltRmtiV2x1SWl3aWNHRnpjM2R2Y21RaU9pSmhaRzFwYmlKOQo=
ZXlKMWMyVnlUbUZ0WlNJNkltRmtiV2x1SWl3aWNHRnpjM2R2Y21RaU9pSmhaRzFwYmlKOQ==
you see in two encode different in end line in ("o=" != "==")
also i know resolve this but you should fix in end line encode match with other
language
Thanks,
Ramin

Ramin Farajpour Cami added the comment:
why any update in python 2.7?
you should using a function this code change :
enc_sec =
ZXlKMWMyVnlUbUZ0WlNJNkltRmtiV2x1SWl3aWNHRnpjM2R2Y21RaU9pSmhaRzFwYmlKOQo=
url = re.sub('\o=$','',enc_sec)
result = url.replace('\n','==')
print result

Ramin Farajpour Cami added the comment:
no close plz,
i using python 2.7.3 i get this output without "\n"?
code:
json_obj='{"userName": "admin", "password": "admin"}'
enc = json_obj.encode("base64")
print enc
enc_sec = re.sub('\n$','',enc)
print enc_sec
sec = enc_sec.encode("base64")
print sec
Output:
{"userName": "admin", "password": "admin"}
