将Webhook配置为触发执行动作的JavaScript Azure函数。在测试时，一个webhook事件触发一次执行Azure函数，仅对该事件执行操作。这是期望的行为。
但是，当在Azure UI中激活Azure功能时，该功能以设置的间隔（似乎每5分钟执行一次）执行，不仅对最近的webhook事件而且对所有先前的webhook事件都执行操作。即使在上一个时间间隔内未发生任何事件，也会重复此行为。换句话说，每隔5分钟就会对发生的所有事件执行一次操作。当我使用与本地测试相同的代码在UI中进行测试时，也是如此。
我已经调查了日志和相关的存储帐户，监视了控制台，并单击了我能想到的任何其他内容，但是找不到任何可能触发的缓存或历史事件列表。
function.json：
{
"disabled": false,
"bindings": [
{
"authLevel": "function",
"type": "httpTrigger",
"direction": "in",
"name": "req",
"methods": [
"get",
"post"
]
},
{
"type": "http",
"direction": "out",
"name": "res"
}
]
}
谢谢您的见解。
