I'm trying to test my web server's login with Postman. First, I send a GET request to my login url, and I get a CSRF token as a cookie. Then, I make a POST request to that login page, with my username, password, and CSRF token.
My problem is, when I do this in Postman, I get a 403 forbidden error when I try to make that POST request to login. I'm copying the CSRF token received and putting it as one of the POST parameters, and I'm using a valid username and password. Is there anything I'm overlooking here?
You need to set it as a header in the request, not in the body. X-CSRFToken is the key and the value is CSRF token from the cookie. This will work if you are using an API framework like Tastypie or Django Rest Framework.
If you are authenticating without an API layer you would need to actually attach the cookie or create one with the CSRF token. This post explains it.
Try installing the Postman Interceptor Extension on GoogleChrome. It worked for me.
Works for me :
Set in Postman Header :
KEY : Authorization
Value : Token "Your token"

So I've been trying to use Djoser JWT and I don't know how to login in it. As far as I know you create a request with your login credentials to this url /jwt/create/ and get the access and refresh token and maybe get the user object from /users/me/. This is where I got stuck, where do I go from here?
You correctly understood the first step of the process. Basically, you can now:
Add the access token in the header of your next requests.
This will transparently authenticate the user thanks to the Simple JWT plugin and you will be able to access him with the usual request.user in the views.
Refresh the access token each time you get a 401 response.
The access token is supposed to be short-living for security concerns and a 401 response from the server indicates that the one your are using is expired. So you have to get a new one by sending the refresh token to the token/refresh/ API and, then, make your request again.
You can read this article if you need more detailed explanations about this process or JWT.
I am getting this error please haldle the csrf token in django project.When I first made an AJAX call with a POST request, I got a HTTP 403 Forbidden error. A quick debug led me to the CSRF authorisation problem. The backend refused to authorise the request because there is no accompanying CSRF token to prove that the request is not from a foreign site.
From the documentation:
"The CSRF middleware and template tag provides easy-to-use
protection against Cross Site Request Forgeries. This type of attack occurs when a malicious website contains a link, a form button
or some JavaScript that is intended to perform some action on your
website, using the credentials of a logged-in user who visits the
malicious site in their browser."
Therefore, when making a POST request, you should always include a CSRF token.
For more information, including how to use it with AJAX calls, please refer to the documentation:

I have implemented an endpoint for login, using the django-rest-framework and TokenAuthentication. What i want, is after the login, the user to be authenticated and can navigate on the website.
I know that any get request on any protected using authentication uri should contain the token in the headers, so that the user can be authenticated. Everything is fine with that, if i could do all the get requests adding the token manually.
But what i do not understand is, how can i add the token in the headers when for example the user manually does the request by writing the url?
Let's say that the uri /api/ is protected and requires an authenticated user.
The user logs in, and i save the token either on the cookies or in the localstorage.
Now the user does a http get request on /api/. The token is not placed in the headers, so the response is: "Not authenticated".
So the question is, how can i add the token on any subsequent request after user logs in successfully? Maybe the backend could check the cookies for a valid token, but isn't there any better and safer solution than this?
As I believe from the question you want to add the token to all API which is consumed by your client whether App/Web. So in both people prefer to store that token either in cookies or in local storage. Once user logged out api consumer also flush that key.
While the site loads smoothly through the browser,but when i send a POST request via postman or a REST API client, i am getting a csrf error.
"CSRF cookie not set."
IS THERE A WAY TO SEND A REQUEST SKIPPING CSRF?
You need to use csrf_exempt decorator on your view : this will disable the check of the csrf token
https://docs.djangoproject.com/en/2.0/ref/csrf/#django.views.decorators.csrf.csrf_exempt
I'm using the chrome rest client to test the api calls.
A GET request is working fine but while making a POST request , getting 403 hidden response.
description is
CSRF verification failed. Request aborted
I'm setting as Content-Type=application/json.
One way would be to use #csrf_extempt, but seems to be good choice.
How to resolve above issue ?
Using #csrf_extempt is infact a good practice when you are providing an API to your site. Cross-site request forgery is what csrf is but in your case it won't be a forgery since an api can(should) be called from any site but yours.
.
Moreover sharing csrf token will prove to be very tricky.
In thre request, include an X-CSRFToken header with the CSRF token value obtained from the csrftoken cookie.
