  • react hook + antd upload 通过fileList控制文件列表展示status为uploading

    项目是用的react hook写的,引入了antd 的upload上传组件,页面效果如下

    代码

    import React, { useState } from 'react'
    import { Modal, Form, Upload, message, Button } from 'antd'
    import { UploadOutlined } from '@ant-design/icons'
    import { TableListItem } from '@/services/data.d'
    import { importByExcelUrl } from '@/services/manually'
    import { validFileSize } from '@/utils/validate'
    
    export interface FormValueType extends Partial<TableListItem> {
      time?: string;
      [propName: string]: any
    }
    
    const FormItem = Form.Item
    
    interface CreateFormProps {
      modalVisible: boolean;
      onCancel: () => void;
      onConfirm: (values: FormValueType) => void;
      values: any
    }
    const formLayout = {
      labelCol: { span: 7 },
      wrapperCol: { span: 13 },
    }
    
    const UploadForm: React.FC<CreateFormProps> = (props) => {
      const { modalVisible, onConfirm, onCancel } = props
      const [bussinessFileList, setFilelist] = useState<any[]>([])
      const [uploadFileList, setUploadFilelist] = useState<any[]>([])
      const [form] = Form.useForm()
    
      form.setFieldsValue({})
    
      const uploadprops = {
        name: 'file',
        action: importByExcelUrl(),
        headers: {
          authorization: 'authorization-text',
        },
        accept:
          '.csv,.xls,.xlsx, application/vnd.openxmlformats-officedocument.spreadsheetml.sheet, application/vnd.ms-excel',
        data: { businessCode: props.values },
        disabled: bussinessFileList.length === 1,
        fileList: uploadFileList,
        beforeUpload(file: any) {
          // console.log(6, file, uploadFileList.length, validFileSize(file))
          if (uploadFileList.length > 0) {
            message.warning('只能上传一个文件')
            return false
          }
          if (file.size === 0) {
            message.error('文件不能为空')
            return false
          }
          return validFileSize(file)
        },
        onChange(info: any) {
          let files: any[] = [...info.fileList]
          if (info.file.status === 'done') {
            if (info.file.response) {
              if (info.file.response.responseCode === '000000') {
                // files = [...info.fileList]
                message.success(`${info.file.name} 文件上传成功`)
              } else {
                message.error(info.file.response.responseMsg)
              }
            } else {
              message.error(`${info.file.name} 上传失败.`)
            }
          } else if (info.file.status === 'error') {
            message.error(`${info.file.name} 上传失败.`)
          }
          files = files.filter((item : any) => {
            return item.response?.responseCode === '000000'
          })
          files = JSON.parse(JSON.stringify(files))
          console.log(66666, info, files)
          setUploadFilelist(files)
          setFilelist(files)
        },
      }
    
      const renderContent = () => {
        return (
          <>
            <FormItem
              name='uploads'
              label='上传模板'
              required
              rules={[{ validator: (rule, value, callback) => {
                if (value && value.fileList && value.fileList.length) {
                  console.log(77, value)
                  if (value.file.response && value.file.response.responseCode === '000000') {
                    callback()
                  } else if (value.file.status && value.file.status === 'uploading') {
                    callback()
                  } else {
                    callback('文件信息有误,请删除后上传正确文件')
                  }
                } else callback('请选择文件上传')
              } }]}
            >
              <Upload {...uploadprops}>
                <Button>
                  <UploadOutlined /> 点击上传
                </Button>
              </Upload>
            </FormItem>
          </>
        )
      }
      const handleConfirm = async() => {
        const fieldsValue = await form.validateFields()
        // console.log(fieldsValue)
        onConfirm(fieldsValue)
      }
    
      return (
        <Modal
          destroyOnClose
          title='上传模板'
          visible={modalVisible}
          onOk={() => handleConfirm()}
          maskClosable={false}
          onCancel={() => onCancel()}
        >
          <Form
            {...formLayout}
            form={form}
            initialValues={{}}
          >
            {renderContent()}
          </Form>
        </Modal>
      )
    }
    
    export default UploadForm

    想做到的效果是用户文件上传正确,才展示在页面上,上传错误不展示在页面上.使用了upload的fileList属性,发现文件上传状态一直是uploading

    在官网找了一圈答案https://github.com/ant-design/ant-design/issues/2423这个issue里有问题描述,试了里面的一些方法还是不起作用

    后面发现实际问题是,fileList这个属性不能设置为空数组

    这里已经说得很明白了,所以说想用这个属性来控制文件,就必须保证不会为空数组,但是这个跟我的需求不符,所以后来没用这个属性,是用form的rules来提示客户删除不正确的文件重新上传

    但是如果一定要实现这个功能可以自己写fileList

     <FormItem
              name='uploads'
              label='上传模板'
              required
              rules={[{ validator: (rule, value, callback) => {
                if (value && value.fileList && value.fileList.length) {
                  console.log(77, value)
                  if (value.file.response && value.file.response.responseCode === '000000') {
                    callback()
                  } else if (value.file.status && value.file.status === 'uploading') {
                    callback()
                  } else {
                    callback('文件信息有误,请删除后上传正确文件')
                  }
                } else callback('请选择文件上传')
              } }]}
            >
              <>
                <Upload {...uploadprops} showUploadList={false}>
                  <Button>
                    <UploadOutlined /> 点击上传
                  </Button>
                </Upload>
                {bussinessFileList.length ? <ul>     // 大概的就是这样,具体样式自己要调整一下
                  {bussinessFileList.map(item => <li key={item.uid}>
                    {item.name}
                  </li>)}
                </ul> : null}
              </>
            </FormItem>

    这样写要注意一个问题,formtien默认值会获取内部的一个闭合标签的值,这里加了列表之后,form rules里面的value将会获取不到file上传的内容,可以换成bussinessFileList判断
