【AntDesign】文件自定义上传组件

技术栈

AntDesign 版本 ： 3x

效果图如下
官网示例给的是标准上传模式, 此处用的是自定义上传模式(customRequest)

ps : 此处是文件上传, 和图片上传实际共用的都是antd Upload组件, 图片上传组件传送门 : https://blog.csdn.net/qq_45481971/article/details/130576408?spm=1001.2014.3001.5501
( 代码大致相同, 代码详解这里就不写了, 可以参考图片上传组件详解~ )

代码

子组件代码 ↓

import React, {
    
     useState, useImperativeHandle } from 'react'
import {
    
     Button, Upload, Icon, message } from 'antd'
import PropTypes from 'prop-types'

     uploadFunc, uploadSmallFunc } from '../../common/uploadFunc'

const UploadCom = (props, ref) => {
    
    
  const {
    
     dataList, disabled, acceptType, type, handleMediaResource } = props
  const [fileList, setFileList] = useState(dataList)
  useImperativeHandle(ref, () => ({
    
     clearUploadList }))
  const clearUploadList = () => {
    
    
    setFileList([])
  }
  // 自定义上传逻辑
  const customRequest = async options => {
    
    
    const {
    
     file } = options
    let suffixs = []
    let usage = ''
    suffixs = ['pdf']
    usage = 'pdf'

      uploadSmallFunc(file, suffixs, usage)

              lastModifiedDate: file.lastModifiedDate,
              originFileObj: file,
              percent: 100,
              type: file.type,
            },
          ]
          setFileList(newFileList)
        }) 
  }

  const showUploadList = {
    
     showRemoveIcon: disabled ? false : true }

        message.success(`${
      
      info.file.name} 上传成功`)
      } else if (info.file.status === 'error') {
    
    
        message.error(`${
      
      info.file.name} 上传失败`)
      }
    },
    onRemove: file => {
    
    
      const index = fileList.indexOf(file)
      const newFileList = fileList.slice()
      newFileList.splice(index, 1)
      handleMediaResource({

    },
    defaultFileList: [],
    beforeUpload: file => {
    
    
      // 限制文件大小 小于20m
      const isFile20M = file.size / 1024 / 1024 > 20
      if (isFile20M) {
    
    
        message.error('文件大小超出20M限制，请修改后重新上传')
        return false
      }
    },
  }

  return (
    <div>
      <Upload
        {
    
    ...props2}
        showUploadList={
    
    showUploadList}
        fileList={
    
    fileList}

    customRequest}
      >
        <Button size="large" style={
    
    {
    
     width: '150px' }} disabled={
    
    disabled}>
          <Icon style={
    
    {
    
     fontSize: '18px' }} type="upload" />
          点击上传
        </Button>
      </Upload>
    </div>
  )
}
export default React.forwardRef(UploadCom)

父组件(部分)代码 ↓

  // 通过ref向子组件传递事件
  const uploadComRef= React.createRef(null)

  // 提交时清除图片组件数据
  const onSubmitFn = e => {
    
    
  	uploadComRef.current.clearUploadList()
  }
  
  // 上传组件
	<UploadCom
	   ref={
    
    uploadComRef}
       type="resourcePdf"
       acceptType=".pdf"
       dataList={
    
    pdfDataList}
       disabled={
    
    editType == 'view' ? true : false}
       handleMediaResource={
    
    handleMediaResource}
    />
