---
## zh-CN
自定义本地预览,用于处理非图片格式文件(例如视频文件)。
## en-US
Customize local preview. Can handle with non-image format files such as video.
```jsx
import { Upload, Button } from 'antd';
import { UploadOutlined } from '@ant-design/icons';
const props = {
action: '//jsonplaceholder.typicode.com/posts/',
listType: 'picture',
previewFile(file) {
console.log('Your upload file:', file);
// Your process logic. Here we just mock to the same file
return fetch('https://next.json-generator.com/api/json/get/4ytyBoLK8', {
method: 'POST',
body: file,
})
.then(res => res.json())
.then(({ thumbnail }) => thumbnail);
},
};
ReactDOM.render(
<Upload {...props}>
<Button icon={<UploadOutlined />}>Upload</Button>
</Upload>,
mountNode,
);
```
