如何正确允许 django rest 框架中的 post 请求？

现在我在创建对 api/v3/exchange/order 的 POST 请求时出错（使用 POST）

Traceback (most recent call last):

我尝试将请求实例更改为 HttpRequest 并且没有任何改变。

我在 external_api.py 中的代码：

from django.shortcuts import render
from django.http import HttpResponse
from django.http import HttpRequest
from django.http import HttpResponse, JsonResponse, HttpResponseRedirect
from rest_framework import routers, serializers, viewsets
from beeqb.models import *
from rest_framework import status
from django.views.decorators.csrf import csrf_exempt
from rest_framework import status
from rest_framework.decorators import api_view
from rest_framework.response import Response
from .serializer import *
from rest_framework.renderers import JSONRenderer
from beeqb.handlers.WalletHandler import select_wallet, get_crypt_wallet, make_sub_wallet
from django.db.models import Q, Sum
import requests

from rest_framework import generics

from .api_lib import *
from beeqb.handlers.ChartHandler import *
from rest_framework.decorators import api_view, schema
from rest_framework.schemas import AutoSchema
from beeqb.models import Order, OrdersTrigger, ORDER_WAIT, ORDER_BUY, ORDER_SELL, ORDER_DONE
from django.template.context_processors import csrf
from rest_framework.views import APIView
from rest_framework.response import Response
import logging

class ApiExternalCCXT(APIView):
    name = ''
    def get(self, request, *args, **kwargs):
        return getattr(self, self.name)(request)

    def post(self, request, *args, **kwargs):
        return getattr(self, self.name)(request)

    @api_view(['POST', 'GET'])
    def api_create_order(self, request):
    “““
    the method must accept POST requests
    HERE SOME CODE
    “““

    def api_get_fetch_orders(self, request):
    “““
    the method accepted GET requests and working fine
    HERE SOME CODE
    “““

我的网址.py

from django.contrib import admin
from django.urls import include, path
from rest_framework import routers
from django.conf.urls import include, url
import beeqb
from .views import ApiCCXT, ApiOrder, Ticker, SymbolsDetails, ApiTransactions, ExampleView
from .serializer import *
from rest_framework.documentation import include_docs_urls
from app_ccxt.external_api import ApiExternalCCXT
import app_ccxt.ChartHandler
from app_ccxt.ApiCCXT.ChartHandlerCCXT import ApiChartHandlerCCXT
urlpatterns = [
  “““ URLS “““
    url(r'^exchange/order',        ApiExternalCCXT.as_view(name='api_create_order')),
  “““ URLS “““

    url(r'^exchange/fetch_open_orders',  ApiExternalCCXT.as_view(name='api_get_fetch_open_orders')),

  “““ URLS “““

]

如果我尝试为 api_get_fetch_orders 方法（exchange/fetch_open_orders）执行 GET rquest——一切正常。

我究竟做错了什么？如何在 api_create_order 方法中获取发布请求？def post() 有什么问题？

我认为 post() 中的所有问题，但无法理解如何修改它以用于多种方法。我需要这个方法和其他几个方法的 POST 请求

我正在使用 GET 请求：return getattr(self, self.name)(request)

同样，我想处理 POST 请求。但在这里我有错误。

如果我只对方法 api_create_order 使用 GET 请求（我从代码中删除了 post() 和 @api_view 表示法），那么一切正常。

你能帮我吗？

UPD： 使用 post() 和 @api_view 表示法对 api_create_order() 方法的 POST/GET 请求。

对于 POST 请求：请求信息：

USER: AnonymousUser

GET: No GET data

POST:
aaa = '123'
bbb = '234'

FILES: No FILES data

COOKIES: No cookie data

对于 GET 请求

Request information
USER     AnonymousUser
GET
Variable    Value
token    '521f5013121d0829a946780cb5763ea41042c132'

number  '1139012'

POST 
No POST data
