Here's sample code for user login for Django Rest Framework:
class Login(APIView):
#csrf_exempt
def dispatch(self, *args, **kwargs):
return super(Login, self).dispatch(*args, **kwargs)
#staticmethod
def post(request):
request_data = JSONParser().parse(request)
if 'email' in request_data and 'password' in request_data:
try:
validate_email(request_data['email'])
except ValidationError:
return JsonResponse({'result': 'E-mail is invalid'}, status=400)
user = authenticate(email=request_data['email'], password=request_data['password'])
if user is not None:
if user.is_active:
try:
token = Token.objects.get(user=user)
except Token.DoesNotExist:
token = Token.objects.create(user=user)
return JsonResponse({'result': 'success', 'token': token.key, 'id': user.id}, status=200)
return JsonResponse({'result': 'E-mail or password is incorrect'}, status=400)
return JsonResponse({'result': 'E-mail or password is empty'}, status=400)
Here's sample for FB login code for Django Rest Framework (from my test project):
class FbLogin(APIView):
authentication_classes = (authentication.TokenAuthentication,)
permission_classes = (permissions.AllowAny,)
#csrf_exempt
def dispatch(self, *args, **kwargs):
return super(FbLogin, self).dispatch(*args, **kwargs)
#staticmethod
def post(request):
request_data = JSONParser().parse(request)
if 'access_token' in request_data:
response = requests.get(
url='https://graph.facebook.com/v2.5/me/',
params={
'access_token': request_data['access_token'],
'fields': 'email,first_name,last_name',
},
)
json_response = json.loads(response.text)
if 'error' not in json_response:
response_photo = requests.get(
url='https://graph.facebook.com/v2.5/%s/picture' % json_response['id'],
params={
'redirect': 'false',
'type': 'large',
},
)
response_photo_json = json.loads(response_photo.text)
response_friends = requests.get(
url='https://graph.facebook.com/v2.5/me/friends/',
params={
'access_token': request_data['access_token'],
'limit': 300,
},
)
generated_password = get_random_string(10, '0123456789abcdefghijklmnopqrstuvwxyz')
try:
json_response_email = json_response['email']
except:
first_name = json_response['first_name'].lower()
last_name = json_response['last_name'].lower()
id = json_response['id']
json_response_email = first_name + last_name + id + '#facebook.com'
try:
current_user = User.objects.get(email=json_response_email)
current_user.set_password(generated_password)
current_user.save()
except User.DoesNotExist:
new_user = User.objects.create_user(email=json_response_email,
password=generated_password)
new_user.provider_id = json_response['id']
new_user.provider_type = 'facebook'
if 'first_name' in json_response:
new_user.first_name = json_response['first_name']
if 'last_name' in json_response:
new_user.last_name = json_response['last_name']
new_user.save()
photo_name = urlparse(response_photo_json['data']['url']).path.split('/')[-1].split('?')[-1]
photo_content = urllib.request.urlretrieve(response_photo_json['data']['url'])
new_user.profile_photo.save(photo_name, File(open(photo_content[0], 'rb')), save=True)
user = authenticate(email=json_response_email, password=generated_password)
try:
token = Token.objects.get(user=user)
except Token.DoesNotExist:
token = Token.objects.create(user=user)
if user is not None:
if user.is_active:
fullname = json_response['first_name'] + ' ' + json_response['last_name']
return JsonResponse({'result': 'success', 'token': token.key, 'name': fullname}, status=200)
return JsonResponse({'result': 'User access token is incorrect'}, status=400)
