我正在构建一个NFT markeplace项目,当我试图获取创建的NFT时,我得到了这个错误:enter image description here .
我得到错误的页面的代码是这样的:
import React, {useEffect, useState, useContext} from "react";
import Style from "../CosmetizarePagini/paginatoateNFTurile.module.css";
import {Incarca} from "../module/indexmodule";
import ImagineCreazaNFT from "../ImagineCreazaNFT/ImagineCreazaNFT";
import {NFTMarketplaceContext} from "../Context/NFTMarketplaceContext";
const ToateNFTurile = () =>
{
const {fetchNFTs, currentAccount} = useContext (NFTMarketplaceContext);
const [nfts, setNfts] = useState ([]);
const [nftsCopy, setNftsCopy] = useState ([]);
useEffect(() =>
{
try
{
if (currentAccount)
{
fetchNFTs().then((items) =>
{
setNfts(items);
setNftsCopy(items);
});
}
}
catch (error) {console.log ("Reincarca browser-ul, a aparut o eroare!", error);}
}, []);
return (
<div className={Style.paginatoateNFTurile}>
<h1><center>Colectie NFT-uri</center></h1>
<h2><center>Click pe imagini pentru detalii!</center></h2>
<br></br><br></br><br></br>
{nfts.length == 0 ? <Incarca/> : <ImagineCreazaNFT NFTData={nfts}/>}
</div>
);
};
export default ToateNFTurile;
我想提一下,我是一个初学者程序员,我(不成功:))试图解决它,但无济于事。任何帮助是赞赏。
谢谢!
尝试修改上下文文件中的代码,但出现相同错误。

您可以
console.log()
items
变量进行检查,可能是它不是一个正确的数组或null或未定义.因为它不是正确的数组,你得到这个错误后,API响应.
