- 当需要使用拖拽交互时。

| accept | 接受上传的文件类型, 详见 [input accept Attribute](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/file#accept) | string | 无 | |
| action | 上传的地址 | string\|(file) => `Promise` | 无 | |
| method | 上传请求的 http method | string | 'post' | 1.5.0 |
| directory | 支持上传文件夹([caniuse](https://caniuse.com/#feat=input-file-directory) | boolean | false | |
| beforeUpload | 上传文件之前的钩子,参数为上传的文件,若返回 `false` 则停止上传。支持返回一个 Promise 对象Promise 对象 reject 时则停止上传resolve 时开始上传( resolve 传入 `File``Blob` 对象则上传 resolve 传入对象)。**注意IE9 不支持该方法**。 | (file, fileList) => `boolean | Promise` | 无 | |
| customRequest | 通过覆盖默认的上传行为,可以自定义自己的上传实现 | Function | 无 | |
| data | 上传所需参数或返回上传参数的方法 | object\|(file) => object | 无 | |
| disabled | 是否禁用 | boolean | false | |
| fileList | 已经上传的文件列表(受控) | object\[] | 无 | |
| headers | 设置上传的请求头部IE10 以上有效 | object | 无 | |
| listType | 上传列表的内建样式,支持三种基本样式 `text`, `picture``picture-card` | string | 'text' | |
| multiple | 是否支持多选文件,`ie10+` 支持。开启后按住 ctrl 可选择多个文件。 | boolean | false | |
| name | 发到后台的文件参数名 | string | 'file' | |
| previewFile | 自定义文件预览逻辑 | (file: File \| Blob) => Promise<dataURL: string> | 无 | 1.5.0 |
| showUploadList | 是否展示 uploadList, 可设为一个对象,用于单独设定 showPreviewIcon 和 showRemoveIcon | Boolean or { showPreviewIcon?: boolean, showRemoveIcon?: boolean } | true | |
| supportServerRender | 服务端渲染时需要打开这个 | boolean | false | |
| withCredentials | 上传请求时是否携带 cookie | boolean | false | |
| openFileDialogOnClick | 点击打开文件对话框 | boolean | true | |
| remove   | 点击移除文件时的回调,返回值为 false 时不移除。支持返回一个 Promise 对象Promise 对象 resolve(false) 或 reject 时不移除。               | Function(file): `boolean | Promise` | 无   | |
| transformFile   | 在上传之前转换文件。支持返回一个 Promise 对象   | Function(file): `string | Blob | File | Promise<string | Blob | File>` | 无   | 1.5.0 |
### 事件
| 事件名称 | 说明 | 回调参数 | 版本 |
| --- | --- | --- | --- |
| change | 上传文件改变时的状态,详见 [change](#change) | Function | 无 | |
| preview | 点击文件链接或预览图标时的回调 | Function(file) | 无 | |
| download | 点击下载文件时的回调,如果没有指定,则默认跳转到文件 url 对应的标签页。 | Function(file): void | 跳转新标签页 | 1.5.0 |
| reject | 拖拽文件不符合 accept 类型时的回调 | Function(fileList) | 无 | |
### change
> 上传中、完成、失败都会调用这个函数。
文件状态改变的回调,返回为:
```jsx
{
file: { /* ... */ },
fileList: [ /* ... */ ],
event: { /* ... */ },
}
```
1. `file` 当前操作的文件对象。
```jsx
{
uid: 'uid', // 文件唯一标识,建议设置为负数,防止和内部产生的 id 冲突
name: 'xx.png', // 文件名
status: 'done', // 状态有uploading done error removed
response: '{"status": "success"}', // 服务端响应内容
linkProps: '{"download": "image"}', // 下载链接额外的 HTML 属性
xhr: 'XMLHttpRequest{ ... }', // XMLHttpRequest Header
}
```
2. `fileList` 当前的文件列表。
3. `event` 上传中的服务端响应内容,包含了上传进度等信息,高级浏览器支持。
