Question

我有以下类用于用户的付款进度当请求为POST时，我在会话中设置金额，如request.session['amount'] = amount 当请求为GET时，我应该得到会话，但会话是安全的，if语句if 'amount' in request.session:总是假的。我该如何解决这个问题？

class PaidApiView(APIView):
    MMERCHANT_ID = '??????????'  # Required
    ZARINPAL_WEBSERVICE = 'https://www.zarinpal.com/pg/services/WebGate/wsdl'  # Required
    amount = None  # Required
    description = None  # Required
    products = None
    email = 'user@userurl.ir'  # Optional
    mobile = '09123456789'  # Optional
    CallbackURL = 'http://127.0.0.1:8000/store/paid/'

    def post(self, request, *args, **kwargs):

        amount = request.data['amount']
        products = request.data['products']
        productstitle = request.data['productstitle']
        productsTitlestr = ''.join(productstitle)

        self.amount = amount
        self.products = products
        self.description = productsTitlestr

        request.session['amount'] = amount


        client = Client(self.ZARINPAL_WEBSERVICE)
        result = client.service.PaymentRequest(self.MMERCHANT_ID,

                                                            request.GET['Authority'],
                                                            self.amount)

            else:

                return Response('Transaction failed or canceled by user')

        else:
            return Response(status=status.HTTP_400_BAD_REQUEST)

如果您已激活SessionAuthentication类，则将拥有会话变量。但可能您使用的是TokenAuthentication，因此您最好的选择是将数据保存在表中并在每次请求时加载它。

django rest无法在get请求中获取会话变量
