我试图在 django restframework 中接收 json 格式的数据并立即使用这些数据，但我意识到我收到“NoneType”对象不可下标的错误，我觉得我需要使用cleaned_data，但我不知道如何在rest 中使用cleaned_data框架...这是我的代码：

@api_view(['GET', "POST"])
def home(request):
    if request.method == 'POST':     
        name = request.data.get('name')
        email = request.data.get("email")
        amount = request.data.get("amount")
        phone = request.data.get("phone")

        return redirect(str(process_payment(name, email, amount, phone)))
    else:    
        responseData = {  
            "Homepage": "Payment"
        }
        return Response(responseData)

这是我的回溯错误：

我已经修好了。我在流程付款时打印了响应以查看错误消息，所以我得到了：

{'status': 'error', 'message': 'Invalid authorization key', 'data': None}

我现在记得我在早上更改了我的密钥，所以我从我的仪表板上得到它并进行了必要的更正，一切都开始工作了。

错误答案：只需替换request.data为request.POST

已编辑

我看到你的回溯，发现问题出views.py在你使用的地方的第 55 行response['data']。没有！
