我有一个基于类的视图，其中有一个put函数，并试图将request.body导入json。

from django.views import View
import json
class StudentView(View):
    def put(self, request):
        body = request.body #b'name=Arpita+kumari+Verma&roll=109&city=USA'
        json_body = json.loads(body) # JSONError 'expecting dict values but given bytes object'
        # I want something like this
        # {
        #      'name':'Arpita kumari Verma',
        #      'roll':109,
        #      'city':'USA',
        # }
        json_dumped_data = json.dumps(json_body)
        return HttpResponse(json_dumped_data, content_type="application/json")

我的请求app

url = 'http://127.0.0.1:8000/api/student/'
json_data = {
    'name':'Arpita kumari Verma',
    'roll':109,
    'city':'USA'
}
results = requests.put(url, json_data)
