【问题描述】：

当订阅收费失败时，我在尝试接收条纹信号时收到django.utils.datastructures.MultiValueDictKeyError，

这是回溯

Traceback (most recent call last):

[13/Nov/2021 09:36:29] "POST /zebra/webhooks/ HTTP/1.1" 500 121292

我正在使用

django 2.2 Python 3.7.12

提前感谢任何解决方案和建议。

【参考方案1】：

不需要json.loads，你可以像这样使用request.POST.get()方法

request_data = request.POST.get("request_data")

如果字典中没有 request_data 键，这将返回一个 None 值。

感谢@dichter，您的回复。 request_data = json.loads(request.POST["request_data"]) 行来自 django 的核心模块 zebra。 .../env/lib/python3.7/site-packages/zebra/views.py", line 38, in webhooks
