将数据从Django Function发送到Javascript（无需刷新）

Question

I have a django function

@csrf_exempt
def postdata(request):
    r = requests.post(url ,headers=headers, auth=auth, data=json.dumps(data))
    return HttpResponse(r)

I want to pass r which is a dictionary response from a api to my page main.html

def main(request):
    return render(request, 'livestream/main.html')

how can I pass 'r' into a previously loaded page? Main.html calls postdate with an ajax call. I would prefer if main.html doesn't refresh, but I'm ok if it has to.

I'm not sure if it matters, but I'm using a mysql server

Thanks

Answer 1

views.py

# data should be a list of dictionaries and not a queryset
return HttpResponse(json.dumps(data), content_type="application/json")

livestream/main.html

$.ajax({
  success: function(data) {
    console.log(data); // here is your server response
  }
});

Just change your view to return JSON:

import json

from django.http import HttpResponse


@csrf_exempt
def postdata(request):
    r = requests.post(url ,headers=headers, auth=auth, data=json.dumps(data))
    return HttpResponse(json.dumps(r, ensure_ascii=False),
        content_type='application/json')

Then use that JSON to do whatever you need on the client-side.
