如何在连接到第三方后通过多张图片进行映射 api

how to map through multiple images, after connecting to a third party api

我已成功连接到 api,其中有 returns 条狗的图像。但是,我坚持如何在不重复代码的情况下映射多个图像。我基本上想显示一个带有(比方说 9)张图片的网格,所有图片都来自 api.

目前,它显示一张图像,其下方映射有一个 json 对象。

App.js

import './App.css';
import './Dog.js';
import FetchAPI from './FetchAPI';



function DogApp() {

  return (
    <div className="DogApp">
     <FetchAPI />
    </div>
  );
}

export default DogApp;

FetchAPI.js

import React, { useState, useEffect } from 'react'

const FetchAPI = () => {

    const [data, setData] = useState([]);

    const apiGet = () => {
        const API_KEY = "";
        fetch(`https://api.thedogapi.com/v1/images/search?API_KEY=${API_KEY}`)
            .then((response) => response.json())
            .then((json) => {
                console.log(json);
                setData(json);
            });
    };

    useEffect(() => {           //call data when pagee refreshes/initially loads 
        apiGet();
    }, []);


    return (

        <div>
            {data.map((item) => (
                <img src={item.url}></img>
            ))}

            My API
            <button onClick={apiGet}>Fetch API</button>
            <pre>{JSON.stringify(data, null, 2)}</pre>
            <br />


        </div>



    )
}

export default FetchAPI;

如果您的 API returns 一次只有一张图片,并且您希望单击按钮时有更多图片,那么您应该将新图片附加到数组中,例如:

   const apiGet = () => {
    const API_KEY = "";
    fetch(`https://api.thedogapi.com/v1/images/search?API_KEY=${API_KEY}`)
        .then((response) => response.json())
        .then((json) => {
            console.log(json);
            setData([...data,json]); // if json is single object
            // setData([...data,...json]); // if json is array of one object then you should use this line
        });
};
