405 POST method not allowed

Question

I'm trying to develop a REST provider with OAuth. I'm using Django RESTFramework and DjangoOAuthToolkit. I did a GET and it works perfectly but I'm trying to use a POST and the server responds with {"detail": "Method 'POST' not allowed."} This is my code:

# views.py
@api_view(['POST'])
def pruebapost(request):
    usuario = User()
    access_token = Token.objects.get(
        key=request.POST['oauth_token']
    )
    usuario = access_token.user
    content = {'saludo': usuario.username}
    return Response(content)

# settings.py
OAUTH_AUTHORIZE_VIEW = 'principal.views.oauth_authorize'
SESSION_SERIALIZER = 'django.contrib.sessions.serializers.JSONSerializer'
REST_FRAMEWORK = {
   'DEFAULT_RENDERER_CLASSES': (
        'rest_framework.renderers.JSONRenderer',
    ),
   'DEFAULT_PARSER_CLASSES': (
        'rest_framework.parsers.JSONParser',
    ),
   'DEFAULT_AUTHENTICATION_CLASSES': (
        'rest_framework.authentication.OAuthAuthentication',
    ),
}

And I'm using this as a "test" client:

import urlparse
import oauth2 as oauth
import requests

consumer_key = "clave"
consumer_secret = "secreto"
consumer = oauth.Consumer(consumer_key, consumer_secret)
client = oauth.Client(consumer)
resource_url = 'http://blablabla.pythonanywhere.com/prueba'
consumer = oauth.Consumer(key='clave', secret='secreto')
token = oauth.Token(key='e7456187a43141af8d2e0d8fa99b95b9',
                    secret='3wRIKoacff16tcew')

oauth_request = oauth.Request.from_consumer_and_token(
    consumer,
    token,
    http_method='POST',
    http_url=resource_url,
    parameters={'hola':'pepe'}
)
oauth_request.sign_request(
    oauth.SignatureMethod_HMAC_SHA1(),
    consumer,
    token
)
url = oauth_request.to_url()
response = requests.post(url, oauth_request.to_postdata())
print response.content

I don't understand what REST Framework documentation says about 405 Method not allowed

"Raised when an incoming request occurs that does not map to a handler method on the view."

Thanks

Problem solved, I miss one slash on the url.

This response code (405) can come from any number of issues, but it generally ends up that either you are using the wrong URL (as in this case), or you are using the wrong request method. Sometimes it's both!

Quite often I see people getting this issue when they are trying to update an individual resource (/api/res/1), but they are using the list url (/api/res) which doesn't allow the request to be made. This can also happen in the reverse, where someone is trying to create a new instance, but they are sending a POST request to the individual object.

In some cases, the wrong url is being used, so users are requesting a standard non-API view and thinking it is an API view (/res instead of /api/res). So make sure to always check your urls!

Answer 2

class ApiIndexView(APIView)

instead of this please "import from rest_framework import generics" and change it to

class ApiIndexView(generics.ListCreateAPIView) 

there are many views in generic listcreateAPIview is used for get and post and createapiview is used only for post methods
