Quary params transformation is not one-to-one

[TheStaticTurtle]

Hi,

django-revproxy does not provide a one-to-one transformation of query parameters.
For example, querying the following url:

• /src/components/Window.vue?vue&type=style&index=0&scoped=e74fd897&lang.css

is being transformed to:

• http://127.0.0.1:3000/src/components/Window.vue?vue=&type=style&index=0&scoped=e74fd897&lang.css=

(Note the equal sign at the end)

It's a weird and stupid issue to have, but for some reason, the vitejs dev server returns a different value if the equal sign is present or not.

Right now, I'm fixing it by overriding get_encoded_query_params:

def get_encoded_query_params(self):
     get_data = encode_items(self.request.GET.lists())
     params = urlencode(get_data)
     if params.endswith("lang.css="):
          return params[:-1]
     return params

But this is a very static and specific patch to my issue.

Looking at the source for urlencode however, I don't think there is a way to configure it to not use an equal it's hard-coded to use k + '=' + v
