Bypass csrf

[khanetor]

I have the use case of a mobile client app accessing graphql resource with Apollo Client. However, the client cannot access because of CSRF validation. In web I can get the token from cookie, but there is no cookie in mobile app. How can I solve this issue?

Hi @nlhkh!

You can do something like:

from django.conf.urls import url
from django.views.decorators.csrf import csrf_exempt
from graphene_django.views import GraphQLView

urlpatterns = patterns(
    # ...
    url(r'^graphql', csrf_exempt(GraphQLView.as_view(graphiql=True))),
    # ...
)

Thanks @syrusakbary

@syrusakbary I had to do this after deploying my Django app to a live server to get GraphiQL to work on the web. Is that intended or should it find the CSRF token automatically?

@syrusakbary @nlhkh @Vitiell0
Now we can pass the csrf token in the request headers
reactql/kit#77

I have been trying to make a solution like this but my JS foo isn't strong enough.

@syrusakbary is it possible to disable CSRF for a specific resolver/mutation instead of disabling it for everything?

I have a resolver that will be used by an external service (not my app), so it's not possible for it to use a CSRF token. But I don't want to disable CSRF entirely just because of that one resolver.

It would be great if the graphene-django docs could explain how to pass the CSRF token from a javascript client (preferably appollo). If I find out myself I will post it here. My latest attempt looks like this (note: doesn't work):

import ApolloClient from 'apollo-client';
import { createHttpLink } from "apollo-link-http"
import { InMemoryCache } from "apollo-cache-inmemory"
import { setContext } from "apollo-link-context"
import Cookies from 'js-cookie'

function createClient() {
  const httpLink = createHttpLink({
    uri: 'http://localhost:8000/graphql'
  });
  const authLink = setContext((_, { headers }) => {
    return {
      headers: {
        ...headers,
        "X-CSRFToken": Cookies.get('csrftoken'),
      }
    }
  });

  return new ApolloClient({
    link: authLink.concat(httpLink),
    cache: 'no-cache'
  });
}

@mnieber bruh

import { ApolloLink, concat } from 'apollo-link';
import { HttpLink } from 'apollo-link-http';

const httpLink = new HttpLink({
  uri: `/graphql`,
  credentials: 'same-origin',
});

const csrfMiddleware = new ApolloLink((operation, forward) => {
  operation.setContext(({ headers = {} }) => ({
    headers: {
      ...headers,
      'X-CSRFTOKEN':  Cookies.get('csrftoken'),
    }
  }));

  return forward(operation);
});

export const client = new ApolloClient({
  link: concat(csrfMiddleware, httpLink),
  cache,
});

Thanks @japrogramer, it looks a bit different from my attempt, but unfortunately it also doesn't work.

[japrogramer]

@mnieber maybe your Cookies.get('csrftoken') call isn't working ..
Im not actually calling Cookies.get I don't even have that installed. ..

[japrogramer]

@mnieber Hmm something like this should work.
document.cookies.match(new RegExp('csrftoken=([^;]*)(;|$)'))[0]

also try resetting your cache .. just in case.

[mnieber]

The Cookies.get call is working (I checked it in this particular bit of code, and also, I'm using it in my jquery setup)

[japrogramer]

@mnieber
maybe its your package version.

"apollo-boost": "^0.1.10",
"apollo-link-ws": "^1.0.8",
"apollo-upload-client": "^9.1.0",
"graphql": "^14.0.2",
"graphql-tag": "^2.9.2",

[japrogramer]

@dspacejs you could splitting the schema and merging them, one would be csrf exempt and the combined schema wouldnt

[mnieber]

In the end I solved my problem by using the graphql-request package. This also solved another problem where authentication headers were not included in the request. I would suggest to include this (or something similar) in the graphene-django docs, it would be a great help to get started with graphene-django.

import { request, GraphQLClient } from 'graphql-request'
import Cookies from 'js-cookie'


const client = new GraphQLClient(
  `/graphql`,
  {
    credentials: 'include',
    headers: {
      "X-CSRFToken": Cookies.get('csrftoken')
    }
  }
);
