Django Rest Framework, CSRF and Vue.js

I'm trying to use Vue.js to do some POST methods to my REST Api that I created with Django Rest Framework. Problem is, I'm getting the CSRF Failed: CSRF token missing or incorrect. error when I post. But I can see the csrf cookie, and it's being added to the headers.

Here's my settings:

REST_FRAMEWORK = {
    'DEFAULT_PERMISSION_CLASSES': (
        'rest_framework.permissions.IsAuthenticated',
        'rest_framework.permissions.DjangoModelPermissions'
    ),
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'rest_framework.authentication.SessionAuthentication',
        'rest_framework.authentication.BasicAuthentication'
    )
}

Here's my Vue.js config:

var csrftoken = Cookies.get('csrftoken');
Vue.http.headers.common['HTTP_X_CSRFTOKEN'] = csrftoken;

And here's the relevant part of the headers that were sent:

Cookie:djdt=hide; tabstyle=raw-tab; sessionid=1gl533mrneudxw3l9l2vg0ja1yowwmeo; csrftoken=dN85bhztB1oVRov87BsUrWTM29Ff9sjn
Host:127.0.0.1:8000
HTTP_X_CSRFTOKEN:dN85bhztB1oVRov87BsUrWTM29Ff9sjn
Origin:http://127.0.0.1:8000
Referer:http://127.0.0.1:8000/agencies/6/add-profiles/

As you can see, Cookie.csrf and the HTTP_X_CSRFTOKEN header match

I'm really stumped. Any suggestions?

Get token from cookie:

function readCookie(name) {
    var nameEQ = name + "=";
    var ca = document.cookie.split(';');
    for(var i=0;i < ca.length;i++) {
        var c = ca[i];
        while (c.charAt(0)==' ') c = c.substring(1,c.length);
        if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
    }
    return null;
}

var csrftoken = readCookie('csrftoken');

Send token in headers POST:

  this.$http.post('http://'+document.location.host+'/api//',{params: {foo: 'bar'}}, {headers: {"X-CSRFToken":csrftoken }}).then(function (response) {
            this.response = response.data;
        },
        function (response) {
            console.log(response);
        });

So I'm posting this as an answer to close the question.

The issue was because of the wrong CSRF header name that was sent on request. According to documentation:

As with other HTTP headers in request.META, the header name received from the server is normalized by converting all characters to uppercase, replacing any hyphens with underscores, and adding an 'HTTP_' prefix to the name. For example, if your client sends a 'X-XSRF-TOKEN' header, the setting should be 'HTTP_X_XSRF_TOKEN'.

Also I'm leaving here a reference to my question, which accumulates several problems that may lead to CSRF Failed: CSRF token missing or incorrect. error in Django.
