CSRF with Django, React+Redux using Axios

This is an educational project, not for production. I wasn’t intending to have user logins as part of this.

Can I make POST calls to Django with a CSRF token without having user logins? Can I do this without using jQuery? I’m out of my depth here, and surely conflating some concepts.

For the JavaScript side, I found this redux-csrf package. I’m not sure how to combine it with my POST action using Axios:

export const addJob = (title, hourly, tax) => {
console.log("Trying to addJob: ", title, hourly, tax)
return (dispatch) => {
dispatch(requestData("addJob"));
return axios({
method: 'post',
url: "/api/jobs",
data: {
"title": title,
"hourly_rate": hourly,
"tax_rate": tax
},
responseType: 'json'
})
.then((response) => {
dispatch(receiveData(response.data, "addJob"));
})
.catch((response) => {
dispatch(receiveError(response.data, "addJob"));
})
}
};


On the Django side, I’ve read this documentation on CSRF, and this on generally working with class based views.

Here is my view so far:

class JobsHandler(View):
def get(self, request):
with open('./data/jobs.json', 'r') as f:
jobs = json.loads(f.read())
return HttpResponse(json.dumps(jobs))
def post(self, request):
with open('./data/jobs.json', 'r') as f:
jobs = json.loads(f.read())
new_job = request.to_dict()
id = new_job['title']
jobs[id] = new_job
with open('./data/jobs.json', 'w') as f:
f.write(json.dumps(jobs, indent=4, separators=(',', ': ')))
return HttpResponse(json.dumps(jobs[id]))

I tried using the csrf_exempt decorator just to not have to worry about this for now, but that doesn’t seem to be how that works.

I’ve added {% csrf_token %} to my template.

This is my getCookie method (stolen from Django docs):

function getCookie(name) {
var cookieValue = null;
if (document.cookie && document.cookie !== '') {
var cookies = document.cookie.split(';');
for (var i = 0; i < cookies.length; i++) {
var cookie = cookies[i].trim();
// Does this cookie string begin with the name we want?
if (cookie.substring(0, name.length + 1) === (name + '=')) {
cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
break;
}
}
}
return cookieValue;
}

I’ve read that I need to change the Axios CSRF info:

var axios = require("axios");
var axiosDefaults = require("axios/lib/defaults");
axiosDefaults.xsrfCookieName = "csrftoken"
axiosDefaults.xsrfHeaderName = "X-CSRFToken"

Where do I stick the actual token, the value I get from calling getCookie('csrftoken')?

This Q&A is from 2016, and unsurprisingly I believe things have changed. The answer continues to receive upvotes, so I’m going to add in new information from other answers but leave the original answers as well.

Let me know in the comments which solution works for you.

Option 1. Set the default headers

In the file where you’re importing Axios, set the default headers:

import axios from 'axios';
axios.defaults.xsrfHeaderName = "X-CSRFTOKEN";
axios.defaults.xsrfCookieName = "csrftoken";

Option 2. Add it manually to the Axios call

Let’s say you’ve got the value of the token stored in a variable called csrfToken. Set the headers in your axios call:

// ...
method: 'post',
url: '/api/data',
data: {...},
headers: {"X-CSRFToken": csrfToken},
// ...

Option 3. Setting xsrfHeaderName in the call:

Add this:

// ...
method: 'post',
url: '/api/data',
data: {...},
xsrfHeaderName: "X-CSRFToken",
// ...

Then in your settings.py file, add this line:

CSRF_COOKIE_NAME = "XSRF-TOKEN"

Edit (June 10, 2017): User @yestema says that it works slightly different with Safari[2]

Edit (April 17, 2019): User @GregHolst says that the Safari solution above does not work for him. Instead, he used the above Solution #3 for Safari 12.1 on MacOS Mojave. (from comments)

Edit (February 17, 2019): You might also need to set[3]:

axios.defaults.withCredentials = true
