我是全棧開發(fā)新手，我正在嘗試編寫一些代碼來更好地理解 React JS 和 Material UI 的前端。我使用了卡片組件在后端顯示帖子，但我想顯示個人資料圖像（通過 CardMedia）循環(huán)，所以我決定重寫該組件，如下所示：import React, { Component } from 'react'import {Link} from 'react-router-dom';import dayjs from 'dayjs';import relativeTime from 'dayjs/plugin/relativeTime';import { connect } from 'react-redux';import PropTypes from 'prop-types';import DeletePost from './DeletePost'import PostDialog from './PostDialog'//MUIimport withStyles from '@material-ui/core/styles/withStyles'import CardMedia from '@material-ui/core/CardMedia';import CardContent from '@material-ui/core/CardContent';import Card from '@material-ui/core/Card';import Typography from '@material-ui/core/Typography';import ChatIcon from '@material-ui/icons/Chat'import MyButton from '../../utils/MyButton';const styles = {    card: {        display: "flex",        marginBottom:20,    },    image:{        minWidth: 100,        minHeight: 100,        borderRadius: '50%',        objectFit: 'cover'            },    content:{        objectFit: 'cover'    }        }但圖像看起來呈橢圓形且被拉伸。我該如何解決這個問題？
