我想将图像添加到 CardMedia 组件，但我目前将其作为 base64 字符串，如下所示：iVBORw0KGgoAAAAANSUhEUgAAASwAAACoCAMAAABg99fBOxrQANHibkS1KoplYAFHgUGz85g6Ggnn2ysaMXSlccHislKRm7uI10eB9piJYuPjE3epRveUuwrTNidn9ad2ZMZFxNfoOJjTsOGESjp...所以我尝试将字符串转换为 blob/文件，但之后如何将图像附加到 CardMedia？它似乎在期待图像的路径

指定内容以 base64 编码。我在示例中使用了 svg，只需根据需要更新您的 MIME 类型，例如，image/png
const { Card, CardMedia } = MaterialUI;
ReactDOM.render(
<Card>
<CardMedia
style={{ height: 100, width: 100 }}
