set_cookie raise exception when the value contains Unicode charset

[Xx Johnsua]

Hello everyone,

Following is my code:

def post(self, request, *args, **kwargs):
    self.object = self.get_object()
    form = forms.CommentForm(request.POST or None)
    if form.is_valid():
        response = self.form_valid(form)
        return self._set_cookies(response, form)
...

@transaction.atomic
def form_valid(self, form):
    self.object = form.save(commit=False)
    self.object.ip = get_remote_addr(self.request)
    self.object.save()
    return HttpResponseRedirect(self.get_success_url())

def _set_cookies(self, response, form):
    year = 365 * 24 * 60 * 60
    response.set_cookie('nickname', form.cleaned_data['nickname'], max_age=year)
    response.set_cookie('url', form.cleaned_data['url'], max_age=year)
    response.set_cookie('email', form.cleaned_data['email'], max_age=year)
    return response

But if the form.cleaned_data['nickname'] contains Chinese, an exception is raised:

Traceback (most recent call last):
  File "/usr/local/Cellar/python3/3.5.2_3/Frameworks/Python.framework/Versions/3.5/lib/python3.5/wsgiref/handlers.py", line 138, in run

  File "/usr/local/Cellar/python3/3.5.2_3/Frameworks/Python.framework/Versions/3.5/lib/python3.5/wsgiref/headers.py", line 142, in __bytes__
    return str(self).encode('iso-8859-1')
UnicodeEncodeError: 'latin-1' codec can't encode characters in position 227-228: ordinal not in range(256)

So how to save the unicode data into cookie? I have to urlencode it manually?

https://docs.djangoproject.com/en/1.10/ref/settings/#default-charset

 

I believe your default charset is set to 'iso-8859-1'.
