Dear Django Community,
we have a curious encoding error and we are running out of ideas to solve
the problem.
We build a Django REST Service with the following packages:
dj-database-url 0.5.0
Django 2.2.1
django-filter 2.1.0
django-oauth-toolkit 1.2.0
django-widget-tweaks 1.4.3
djangorestframework 3.9.3
python-decouple 3.1
argon2-cffi 19.1.0
plotly 4.1.1
When we call a specific REST function (e.g.
*@api_view*([*'POST'*])
*@permission_classes*([AllowAny])
def *token*(request):
r = requests.post(*'http://127.0.0.1:8000/rest/oauth2/token/'*,
data={*'grant_type'* : *'password'*,
*'username'* : request.data[*'username'*],
*'password'* : request.data[*'password'*],
*'client_id'* : settings.REST_CLIENT_ID,
*'client_secret'* :
settings.REST_CLIENT_SECRET,},)
return Response(r.json())
)
We are getting a UFT8 encoding error (Traceback see below). The content of
“data” seems to be ok:
data= {'grant_type': 'password', 'username': 'x', 'password': 'x',
'client_id': 'TQmAHzCM2r9nfkruVQw0eMQ0AziSvLAnf4ufvZ1o', 'client_secret':
'GISUGXxa2e4JHejUCImMMUMJMtZ13byvc8fySUvX7shELNLPE5xZBA3p0cvbXvvrPIWgltSkTNZ9a7JHPQswEKHzZEDkl21ekS3T6NefUrzVFsdyRS0A2qOHL1L4Nra5'}
We have the same error on our testing LINUX system and our development
environment on windows. We tried to call the REST function via local
testing method, Android app and CURL – same behavior.
The settings of UNICODE_JSON = True/False causes no difference.
We tried it with a REST function without OAUTH Token creation (username and
password credentials) – same behavior.
But – when we call the function with the arguments REST_CLIENT_ID and
REST_CLIENT_SECRET the function is working fine:
curl -X POST -d
"grant_type=password&username=emilia.muel...@email.com&password=qwertzui"
-u"VAOpqwqOTl99jRVXY63Bv5uNXs2MpJWUlZSwSZBf:cgrDaIjPyAy45Z1yxarT0iP9UOjw7gvbpnMirgwz24A56EeJGONHYSsqs9eVPHAyLrsPZdwfdQxoGPnM4LFtihltxlrX24hCQIIE57JezwSHIJab9VjTwAjS9LxYFVJm"
"127.0.0.1:8000/rest/oauth2/token/"
response: {"access_token": "Fz7yTNSsdUxRaWuMj4Sf4OnPe0Ujf6", "expires_in":
3000, "token_type": "Bearer", "scope": "read write", "refresh_token":
"r9H5E8MK5AAy57ZdiFUJaWaJT63kJL"}
But – when we tried to call the other functions with this token and are getting
the same encoding error (traceback below):
curl -X GET -H "Authorization: Bearer Fz7yTNSsdUxRaWuMj4Sf4OnPe0Ujf6"
127.0.0.1:8000/rest/patient/1
Everything worked fine a few weeks ago, but after a database change the
problem occurs. Setting the DB Model to the previous entries was not
successful.
It would be really great if some of you would have any idea what is working
wrong here!
Thanks in advance!
