How to set charset header in Django 1.11

Question

we are using Django1.11 and we are having some problems because our header Content-Type does not contain the charset part set to UTF-8. Something like this:

Content-Type: application/json; charset=UTF-8

I want to fix that for all endpoints, so I have thought to include a middleware to run after all midlewares have been run. The problem is that I do not know if that's possible. Any ideas? Or alternative solutions?

Answer 1

You can write a custom middleware like this:

from django.utils.deprecation import MiddlewareMixin


class AllIsJsonMiddleware(MiddlewareMixin):

    def process_response(self, request, response):
        response['Content-Type'] = 'application/json; charset=UTF-8'
        return response

But I don't recommend this. This converts all responses to JSON. Best use a framework like https://www.django-rest-framework.org/.

However, can use a standard view respone...

return HttpResponse(data, content_type='application/json; charset=UTF-8')

... or a custom decorator:

from functools import wraps

def json_response(function):
    @wraps(function)
    def wrap(request, *args, **kwargs):
        response = function(request, *args, **kwargs)
        response['Content-Type'] = 'application/json; charset=UTF-8'
        return response
    return wrap

@json_response
def my_view(request):
    # ....
