Django returns 403 error when sending a POST request
when I'm using following Python code to send a POST request to my Django website I'm getting 403: Forbidden error.
url = 'http://www.sub.domain.com/'
values = { 'var': 'test' }
try:
data = urllib.urlencode(values, doseq=True)
req = urllib2.Request(url, data)
response = urllib2.urlopen(req)
the_page = response.read()
except:
the_page = sys.exc_info()
raise
When I'm opening any other website it works properly. domain.com is Django website too, and it works properly too. I think, that's Django config problem, can anyone tell me what should I do to provide access to my script?
Solution 1:
Look here https://docs.djangoproject.com/en/dev/ref/csrf/#how-to-use-it.
Try marking your view with @csrf_exempt
. That way, Django's CSRF middleware will ignore CSRF protection. You'll also need to use from django.views.decorators.csrf import csrf_exempt
. See: https://docs.djangoproject.com/en/dev/ref/csrf/#utilities
Please be advised that by disabling CSRF protection on your view, you are opening a gate for CSRF attacks.
If security is vital to you then consider using @csrf_exempt
followed by @requires_csrf_token
(see: https://docs.djangoproject.com/en/dev/ref/csrf/#unprotected-view-needs-the-csrf-token). Then, in your script pass this token and that's it.
Solution 2:
Does the view that you are posting to have a Django Form on it? If so, I wonder if it's giving a csrf error. I think that manifests itself as a 403. In that case, you'd need to add the {{ csrf_token }} tag. Just a thought.
Solution 3:
The response is 403 because django requires a csrf token (included in the post data) in every POST request you make.
There are various ways to do this such as:
Acquiring the token from cookie and the method has been explained in article enter link description here
or
You can access it from DOM using {{ csrf_token }}, available in the template
So now using the second method:
var post_data = {
...
'csrfmiddlewaretoken':"{{ csrf_token }}"
...
}
$.ajax({
url:'url',
type:'POST'
data:post_data,
success:function(data){
console.log(data);
},
error:function(error){
console.log(error);
}
});
Solution 4:
Or you can allow the permission to make this post request.
Note: Should be used in the cases where you don't need to authenticate the users for posting anything on our server, say, when a new user registers for the first time.
from rest_framework.permissions import AllowAny
class CreateUser(APIView):
permission_classes = (AllowAny,)
def post(self, request, format=None):
return(Response("hi"))
Further Note that, If you want to make that post request form a different domain (in case when the front of the application is in React or angular and the backend is in Django), make sure the add following in the settings file:
-
Update the INSTALLED_APPS to use 'coreHeaders' :
INSTALLED_APPS = [
'corsheaders',
] -
White list your front end domain by adding following to settings file again:
CORS_ORIGIN_WHITELIST = ( 'localhost:8080', )
