您是否設法解決問題？在這種情況下，如果你能夠回答問題和解決方案，那將是非常好的。 – Mattias

HTTP 500錯誤指示存在在代碼中的一些運行時錯誤。我發現錯誤！ JSON數據始終位於請求組件的正文中。行號。 9更新併成功刪除錯誤。

from django.http import HttpResponse 
from django.shortcuts import render 
from django.views.decorators.csrf import csrf_exempt 
import django.utils.simplejson as json 

@csrf_exempt 
def rcvr(request): 
    if request.method=='POST': 
     data = json.loads(request.body.decode(encoding='UTF-8')) 
     if data != None: 
      username = data['username'] 
      return HttpResponse(username) 
     else: 
      return HttpResponse("Nothing was received!") 
    else: 
     return HttpResponse("POST Error!")

您錯過了視圖中的某些步驟以完全啓用CSRF。我假設CSRF是問題，因爲如果沒有正確啓用它會拋出403s。
