我有一個username屬性，已使用它從“登錄”路由傳遞到“產品列表”路由return <Redirect to={{    pathname: "/products",    state: username  }}/>  然后我有一個 <Link to={'/products/${product.id}'}>More info</Link>將我從“產品列表”發送到“單個產品”的方法。當我返回“產品列表”時<Link to={'/products'}>Back</Link>，用戶名消失了。有沒有辦法保留用戶名，以便當用戶登錄并在路線之間來回移動時，它會繼續被存儲？這是我希望存儲用戶名的“產品列表”路線的完整代碼：import React, {useState, useEffect} from 'react';import './Products.css';import {Link} from 'react-router-dom';function Products(props) {  const [products, setProducts] = useState([]);  useEffect(() => {    const fetchProducts = async () => {      const data = await fetch("https://example.com/products");        const products = await data.json();      console.log(products);      setProducts(products);    };    fetchProducts();  }, []);  let username = props.location.state;  return (       <div>       <p className = "HelloUser">Hello, {username}</p>      <p className = "ProductTitle">Our Selection</p>      <div className = "ProductGrid">        {products.map(product =>(        <div className = "ProductBox" key={product.id}>          <img className ="ProductImage" src={product.image} alt="did not load"/>          <p className ="ProductName">{product.name}</p>          <p className ="ProductDiscountedPrice">{"￡" + (Math.round(product.discountedPrice * 100) / 100).toFixed(2)}</p>          <p className ="ProductPrice">{"￡" + (Math.round(product.price * 100) / 100).toFixed(2)}</p>          <Link to={`/products/${product.id}`} className="MoreInfoButton">More info</Link>        </div>        ))}      </div>    </div>  )}export default Products;
