## zh-CN
|
|
|
|
`beforeUpload` 返回 `false` 后，手动上传文件。
|
|
|
|
## en-US
|
|
|
|
Upload files manually after `beforeUpload` returns `false`.
|
|
|
|
```tsx
|
|
import React, { useState } from 'react';
|
|
import { Upload, Button, message } from 'antd';
|
|
import { UploadOutlined } from '@ant-design/icons';
|
|
import type { RcFile, UploadFile, UploadProps } from 'antd/es/upload/interface';
|
|
|
|
const App: React.FC = () => {
|
|
const [fileList, setFileList] = useState<UploadFile[]>([]);
|
|
const [uploading, setUploading] = useState(false);
|
|
|
|
const handleUpload = () => {
|
|
const formData = new FormData();
|
|
fileList.forEach(file => {
|
|
formData.append('files[]', file.originFileObj as RcFile);
|
|
});
|
|
setUploading(true);
|
|
// You can use any AJAX library you like
|
|
