Python Django程序在Postman中工作，但不连接到iOS应用程序

我创建了一个简单的Python程序，它将根据用户输入检索数据并将数据添加到数据库中。为此，我使用了POST方法。该程序在Postman中成功运行，但当我使用API调用从iOS应用程序调用该程序时，该程序显示500错误。错误在exception.py和base.py中。我的程序如下

@api_view(["POST"])
def mg_grt(request):
    if request.method == 'POST':
        name = request.POST['name']
        word = name.lower()
        greet = Greet.objects.filter(grett=word)
        if greet != 0:
            d = Resp(rsp=word)
            d.save()
            r_val = Resp.objects.all()
            rt = random.choice(r_val)
            return HttpResponse(rt)
        else:
            return HttpResponse("Sorry...I didn't understand")
    else:
        return HttpResponse("Bad Request")

错误是：

File "/Library/Python/2.7/site-packages/django/core/handlers/exception.py", line 41, in inner
    response = get_response(request)
  File "/Library/Python/2.7/site-packages/django/core/handlers/base.py", line 187, in _get_response
    response = self.process_exception_by_middleware(e, request)
  File "/Library/Python/2.7/site-packages/django/core/handlers/base.py", line 185, in _get_response
    response = wrapped_callback(request, *callback_args, **callback_kwargs)
  File "/Library/Python/2.7/site-packages/django/views/decorators/csrf.py", line 58, in wrapped_view
    return view_func(*args, **kwargs)

    name = request.POST['name']

    raise MultiValueDictKeyError(repr(key))
MultiValueDictKeyError: "u'name'"

似乎您没有从iOS应用程序发送

name

。让我试试看如果

name

是必填字段，您应该返回400个错误的请求HttpResponse作为最佳做法。您可以尝试在访问name之前记录Request.data吗？
