猫鼬更新循环

Question

我是猫鼬和NodeJs世界的新手，当我执行更新时，我的问题发生了，有效地更新是在数据库中进行的，但时间过了又发生了。

我执行如下更新

router.post("/deleteLead", (req, res) => {
console.log("----------- delete lead -------");
const body = req.body;
deleteLead(body);
});

async function deleteLead(body) {
const id_delete = body.leads.delete[0].id;
const deleteLead = await Model_Lead.updateOne(
{ id: id_delete },
{
is_deleted: true,
}
);
console.log(deleteLead);
};

这是我的应用程序的日志，当我更新一个lead

----------- delete Lead -------
{
acknowledged: true,
modifiedCount: 1,
upsertedId: null,
upsertedCount: 0,
matchedCount: 1
}
{
acknowledged: true,
modifiedCount: 1,
upsertedId: null,
upsertedCount: 0,
matchedCount: 1
}
----------- delete  Lead -------
{
acknowledged: true,
modifiedCount: 1,
upsertedId: null,
upsertedCount: 0,
matchedCount: 1
}
----------- delete  Lead -------
{
acknowledged: true,
modifiedCount: 1,
upsertedId: null,
upsertedCount: 0,
matchedCount: 1
}
----------- delete Lead -------
{
acknowledged: true,
modifiedCount: 1,
upsertedId: null,
upsertedCount: 0,
matchedCount: 1
}

Answer 1

您没有等待deleteLead呼叫的结果。这意味着你的控制器将发送请求并继续前进。

当请求解决时，它可能发生在另一个控制器正在运行的过程中，这将导致查询结果以看起来像的方式被记录，你的控制器不止一次命中MongoDB，当它实际上没有。
