参数 | 说明 | 类型 | 默认值 | 版本 |
---|---|---|---|---|
accept | 接受上传的文件类型, 详见 input accept Attribute | string | - | |
action | 上传的地址 | string | (file) => Promise<string> | - | |
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 或 Blob 对象则上传 resolve 传入对象);也可以返回 Upload.LIST_IGNORE ,此时列表中将不展示此文件。 注意:IE9 不支持该方法 | (file, fileList) => boolean | Promise<File> | Upload.LIST_IGNORE | - | |
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 | - | |
data | 上传所需额外参数或返回上传额外参数的方法 | object|(file) => object | Promise<object> | - | |
defaultFileList | 默认已经上传的文件列表 | object[] | - | |
directory | 支持上传文件夹(caniuse) | boolean | false | |
disabled | 是否禁用 | boolean | false | |
fileList | 已经上传的文件列表(受控),使用此参数时,如果遇到 onChange 只调用一次的问题,请参考 #2423 | UploadFile[] | - | |
headers | 设置上传的请求头部,IE10 以上有效 | object | - | |
iconRender | 自定义显示 icon | (file: UploadFile, listType?: UploadListType) => ReactNode | - | |
isImageUrl | 自定义缩略图是否使用 <img /> 标签进行显示 | (file: UploadFile) => boolean | (内部实现) | |
itemRender | 自定义上传列表项 | (originNode: ReactElement, file: UploadFile, fileList: object[], actions: { download: function, preview: function, remove: function }) => React.ReactNode | - | 4.16.0 |
listType | 上传列表的内建样式,支持四种基本样式 text , picture , picture-card 和 picture-circle | string | text | picture-circle (5.2.0+) |
maxCount | 限制上传数量。当为 1 时,始终用最新上传的文件代替当前文件 | number | - | 4.10.0 |
method | 上传请求的 http method | string | post | |
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 | |
openFileDialogOnClick | 点击打开文件对话框 | boolean | true | |
previewFile | 自定义文件预览逻辑 | (file: File | Blob) => Promise<dataURL: string> | - | |
progress | 自定义进度条样式 | ProgressProps(仅支持 type="line" ) | { strokeWidth: 2, showInfo: false } | 4.3.0 |
showUploadList | 是否展示文件列表, 可设为一个对象,用于单独设定 showPreviewIcon , showRemoveIcon , showDownloadIcon , removeIcon 和 downloadIcon | boolean | { showPreviewIcon?: boolean, showRemoveIcon?: boolean, showDownloadIcon?: boolean, previewIcon?: ReactNode | (file: UploadFile) => ReactNode, removeIcon?: ReactNode | (file: UploadFile) => ReactNode, downloadIcon?: ReactNode | (file: UploadFile) => ReactNode } | true | function: 4.7.0 |
withCredentials | 上传请求时是否携带 cookie | boolean | false | |
onChange | 上传文件改变时的回调,详见 onChange | function | - | |
onDrop | 当文件被拖入上传区域时执行的回调功能 | (event: React.DragEvent) => void | - | 4.16.0 |
onDownload | 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) | |
onPreview | 点击文件链接或预览图标时的回调 | function(file) | - | |
onRemove | 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 | - |
继承自 File,附带额外属性用于渲染。
参数 | 说明 | 类型 | 默认值 | 版本 |
---|---|---|---|---|
crossOrigin | CORS 属性设置 | 'anonymous' | 'use-credentials' | '' | - | 4.20.0 |
name | 文件名 | string | - | - |
percent | 上传进度 | number | - | - |
status | 上传状态,不同状态展示颜色也会有所不同 | error | success | done | uploading | removed | - | - |
thumbUrl | 缩略图地址 | string | - | - |
uid | 唯一标识符,不设置时会自动生成 | string | - | - |
url | 下载地址 | string | - | - |
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:
{file: { /* ... */ },fileList: [ /* ... */ ],event: { /* ... */ },}
file
当前操作的文件对象。
{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,被 beforeUpload 拦截的文件没有 status 属性response: '{"status": "success"}', // 服务端响应内容linkProps: '{"download": "image"}', // 下载链接额外的 HTML 属性}
fileList
当前的文件列表。
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。
请使用 fileList 属性设置数组项的 url 属性进行展示控制。
customRequest
怎么使用?请参考 https://github.com/react-component/upload#customrequest。
fileList
受控时,上传不在列表中的文件不会触发 onChange
后续的 status
更新事件?onChange
事件仅会作用于在列表中的文件,因而 fileList
不存在对应文件时后续事件会被忽略。请注意,在 4.13.0
版本之前受控状态存在 bug 导致不在列表中的文件也会触发。
onChange
为什么有时候返回 File 有时候返回 { originFileObj: File }?历史原因,在 beforeUpload
返回 false
时,会返回 File 对象。在下个大版本我们会统一返回 { originFileObj: File }
对象。当前版本已经兼容所有场景下 info.file.originFileObj
获取原 File 写法。你可以提前切换。
与 antd 无关,原生上传也会失败。请重启 Chrome 浏览器,让其完成升级工作。相关 issue:
