我从pokeapi调用一个对象,确切地说是name属性,在保存文件后第一次呈现时,我得到了名称,但我不知道为什么,重新呈现,然后propertie为null,我得到了一个错误
这是我组件卡
import {
EditOutlined,
EllipsisOutlined,
SettingOutlined,
} from "@ant-design/icons";
import { Avatar, Card, Col, Row } from "antd";
function Pokecard(values: any) {
const { response} = values;
const { Meta } = Card;
return (
<Row gutter={[10, 10]}>
<Col>
<Card
style={{ width: 300 }}
cover={
<img
alt={"" }
src={response && response['sprites']['front_default']}
/>
}
actions={[
<SettingOutlined key="setting" />,
<EditOutlined key="edit" />,
<EllipsisOutlined key="ellipsis" />,
]}
>
<Meta
avatar={<Avatar src="https://joeschmoe.io/api/v1/random" />}
title={response.name}
description=""
/>
</Card>
</Col>
</Row>
);
}
export default Pokecard;
这是我的看法
import { Methods } from "../interfaces/request";
import { useEffect, useState } from "react";
import Pokecard from "../components/pokecard/Pokecard";
import useAxios from "../plugins/Useaxios";
function App2() {
const { response, loading, error } = useAxios({
method: Methods["get"],
url: "/ditto",
body: JSON.stringify({}),
headers: JSON.stringify({}),
});
const [data, setData] = useState([]);
useEffect(() => {
if (response !== null) {
setData(response);
}
}, [response]);
let args: any = {
response,
};
return (
<>
<Pokecard {...args} />;
</>
);
}
export default App2;
这是我的插件axios
import axios from "axios";
import Request from "../interfaces/request";
import { useState, useEffect } from "react";
enum Methods {
get = "get",
post = "post",
default = "get",
}
const useAxios = ({ url, method, body, headers }: Request) => {
axios.defaults.baseURL = "https://pokeapi.co/api/v2/pokemon";
const [response, setResponse] = useState(null);
const [error, setError] = useState("");
const [loading, setloading] = useState(true);
const fetchData = () => {
axios[method](url, JSON.parse(headers), JSON.parse(body))
.then((res: any) => {
setResponse(res.data);
})
.catch((err: any) => {
setError(err);
})
.finally(() => {
setloading(false);
});
};
useEffect(() => {
fetchData();
}, [method, url, body, headers]);
return { response, error, loading };
};
export default useAxios;
我正在学习解构物体
我试图在商店中保存对象,但我得到了一个未定义的
对不起我的英语

你可以试试这样的

尝试直接使用共振
您可以查看不需要useEffect时的示例
