我無法從 mongo 獲取資料，因為 ID 是 ObjectID。我想將其轉換為字串。我無法從 mongo 獲取資料，因為 ID 是 ObjectID，我想將其轉換為字串
enter code here
const SingleProduct = () => {
const {id} = useParams();
const [data, setData] = useState([]);
// const [filter, setFilter] = useState(data);
const [loading, setLoading] = useState(false);
let componentMounted = false;
useEffect(() => {
const getProducts = async () => {
setLoading(true);
// Link database product
const response = await fetch(`http://localhost:8000/api/products/${id}`);
setData(await response.json());
setLoading(false);
}
getProducts();
}, []);
uj5u.com熱心網友回復：
在您的frontend/src/components/products/Products/Products.jsx 檔案中，您可能應該_id 將專案的傳遞給Item組件：
return (
<>
{data.map((item, index) => {
return (
<Item
id={item._id} // Here pass the ObjectId of the item, since `id` is not defined
img={item.image}
title={item.title}
desc={item.desc}
price={item.price}
item={item}
key={index}
/>
);
})}
</>
);
