I'm trying to upload a file to a Django server using Axios post requests in a React app. The server expects a CSRF cookie in the request header.

This request already contains all the methods I can find for setting cookies. Pass document.cookie, set withCredential: true, and specify the Cookie header.

This is my Axios request:

const onSubmit = async (data) => {
    const formData = new FormData()
    formData.append('file', data.file[0])

    const csrftoken = getCookie('csrftoken');
    document.cookie = `csrftoken=${csrftoken}`

    const res = await axiosInstance.post('/upload/', formData, {
        timeout: 0,
        headers: {
            'Cookie': `csrftoken=${csrftoken}`, 
            'Content-Type': 'multipart/form-data',
            'x-csrftoken': csrftoken,
        },
        withCredentials: true,
    })

    console.log(res)
}

This is my Django view:

def upload_file(request):
    form = UploadFileForm()
    if request.method == 'POST':
        form = UploadFileForm(request.POST, request.FILES)

        if form.is_valid():
            file_id = save_file_to_database(request.FILES['file'])
            response = JsonResponse({'id': file_id}, status=201)
            return response
        else:
            response = HttpResponse({'message': 'Upload failed'}, status=400)
            return response

    return render(request, 'upload.html', {'form': form})

Also, I believe I have the relevant Django settings set correctly in settings.py:

CORS_ORIGIN_WHITELIST = (
    "http://localhost:8000",
    "http://127.0.0.1:5173",
)

CSRF_TRUSTED_ORIGINS = [
    "http://127.0.0.1:5173"
]

SESSION_COOKIE_SAMESITE = 'None'

How do I ensure that the CSRF cookie is included in the request header or otherwise meets CSRF requirements? To be sure, the route works if we add @csrf_exempt to the view, so it really should be a CSRF issue.
