我需要纠正这个错误:BSONTypeError:传入的参数必须是12字节的字符串或24个十六进制字符或整数的字符串.&l

Question

服务端代码node.js, express app

app.put('/items/:id', async(req, res) => {
const id = req.params.id;
console.log(id, 'came from id=> app.put');
const qty = req.body;
console.log(qty, 'came from quantity=> app.put');
const filter = {
_id: ObjectId(id)
};
console.log(filter, 'came from filter=> app.put')
const options = {
upsert: true
};
console.log(options, 'came from options=> app.put')
const updatedDoc = {
$set: {
qty: qty,
}
}
console.log(updatedDoc, 'came from updateddoc=> app.put')
const result = await userItems.updateOne(filter, updatedDoc, options);
console.log(result, 'came from result=> app.put')
res.send(result);
})

客户端代码

const handleQuantity = event => {
event.preventDefault();
const qty = event.target.qty.value;
console.log(qty);
const url = `http://localhost:4000/items/${id}`
fetch(url, {
method: 'PUT',
body: JSON.stringify({
qty: qty
}),
headers: {
'Content-type': 'application/json; charset=UTF-8',
},
})
.then((response) => response.json())
.then(data => {
console.log(data);
});
}

我得到的错误:

如果您正在寻找导致错误的原因，那是因为传递给ObjectID()的id无效。
