从POST请求中提取json dict

我想利用Townscript提供的webhook更新模型中的is_paid字段。
数据格式为(json dict):-link(在服务器通知API列下)。
链接上的一条有用信息是:
我们将使用后置参数 data 以以下格式发送数据。
这是python代码:

def payment(request):
    if request.method == "POST":
        posts=request.POST["data"]

        result=json.dumps(posts) #converting incoming json dict to string
        paymentemail(result)    # emailing myself the string (working fine)

        data = posts
        try:
            user = Profile.objects.filter(email=data['userEmailId']).first()
            user.is_paid = True
            user.save()
        except Exception as e: paymentemail(str(e))   # emailing myself the exception

        return redirect('/home')

    else:
        .......

上面代码中与 paymentemail()功能相对应的两封电子邮件是:

"{\"customQuestion1\":\"+9175720*****\",\"customAnswer205634\":\"+917572******\",
    \"customQuestion2\":\"**** University\",\"customQuestion205636\":\"College Name\",\"ticketPrice\":**00.00,
    \"discountAmount\":0.00,\"uniqueOrderId\":\"***********\",\"userName\":\"********\",
    \"customQuestion205634\":\"Contact Number\",\"eventCode\":\"**********\",\"registrationTimestamp\":\"12-12-2019 22:22\",
        \"userEmailId\":\"***********@gmail.com\",etc....}"

我知道反斜杠用于转义引号。
第二封电子邮件:(例外)

string indices must be integers

这是否意味着data = request.POST ['data']给我一个字符串,从而在我使用data ['userEmailId']时导致错误?我该如何处理这个错误?

答案 0 :(得分:0)

def payment(request):
    if request.method == "POST":
        posts=request.POST
        result=json.dumps(posts) #converting incoming json dict to string
        paymentemail(result)    # emailing myself the string (working fine)
        try:
            user = Profile.objects.filter(email=posts['userEmailId']).first()
            user.is_paid = True
            user.save()
        except Exception as e: paymentemail(str(e))   # emailing myself the exception

        return redirect('/home')

    else:
        .......

我更改了posts=request.POST["data"],因为它将仅获取键“数据”的值,而我使用posts=request.POST,以便我们将整个请求作为键值对(dict)获得。 user = Profile.objects.filter(email=posts['userEmailId']).first()
