我正尝试使用webhook从有效负载获取一些数据，在我发送的响应中，我添加了应随有效负载返回的 meta数据，这是我的操作方式（* 以下代码 *），如果您仔细查看键，这里有一个名为meta的键，现在我正尝试从我的webhook视图获取元数据中的一些数据，如下所示：

查看次数.py网页挂钩

@csrf_exempt
@require_http_methods(['POST', 'GET'])
def webhook(request):
    payload = request.body
    order_id = payload['meta']['order_id']
    print(order_id)
    return HttpResponse("testing...")

向支付网关发送响应

@csrf_exempt
def process_payment(request, name, email, amount, order_id):
    auth_token = "FLWSECK_TEST-9efb9ee17d8afe40c6c890294a1163de-X"
    hed = {'Authorization': 'Bearer ' + auth_token}
    data = {
            "tx_ref":''+str(math.floor(1000000 + random.random()*9000000)),
            "amount":amount,
            "currency":"USD",
            "order_id":order_id,
            "redirect_url":f"http://localhost:3000/service-detail/booking/confirmation/{order_id}",
            "payment_options":"card",
            "meta":{
                "order_id":order_id,
                "consumer_id":23,
                "consumer_mac":"92a3-912ba-1192a"
            },
            "customer":{
                "email":email,
                "name":name,
                "order_id":order_id
            },
            "customizations":{
                "title":"ForecastFaceoff",
                "description":"Leading Political Betting Platform",
                "logo":"https://i.im.ge/2022/08/03m/FELzix.stridearn-high-quality-logo-circle.jpg"
                }
            }
    url = ' https://api.flutterwave.com/v3/payments'
    response = requests.post(url, json=data, headers=hed)
    response=response.json()
    link=response['data']['link']
    return redirect(link)

有效负载

{
  "event": "charge.completed",
  "data": {
    "id": 4136234873,
    "tx_ref": "6473247093",

    "account_id": 685622,
    "customer": {
      "id": 1970338,
      "name": "destiny ",
      "phone_number": null,
      "email": "******@gmail.com",
      "created_at": "2023-02-06T11:19:45.000Z"
    },
    "card": {
      "first_6digits": "653188",
      "last_4digits": "2340",
      "issuer": "MASTERCARD  CREDIT",
      "country": "NG",
      "type": "MASTERCARD",
      "expiry": "49/32"
    }
  },
  "event.type": "CARD_TRANSACTION"
}

元数据甚至没有显示在有效负载中，在我可以获取与它一起发送的数据之前，它必须显示在有效负载中吗？

body是字节而不是字符串，因此需要将字符串作为JSON加载。

payload = json.loads(request.body)

元数据不在payload字典中。首先尝试从负载中提取数据密钥，如下所示：

@csrf_exempt
@require_http_methods(['POST', 'GET'])
def webhook(request):
    payload = json.loads(request.body.decode("utf-8"))
    data = payload.get("data")
    if data:
        order_id = data.get("meta", {}).get("order_id")
        print(order_id)
    return HttpResponse("just testing")

编辑：

上面注解JSONDecodeError: Expecting value: line 1 column 1 (char 0) indicates that json.loads()中描述的错误消息要求输入JSON字符串。
请求正文可能为空。您可以通过在调用json.loads()之前打印request.body来检查。
