react-dropzone 参数acceptedFiles 隐式具有any 类型

Question

我正在使用带有 typescript 的 React 18.2.0 和 React Dropzone 14.2.2

 const onDrop = useCallback(acceptedFiles  => {
        setFiles(acceptedFiles.map((file: any) => Object.assign(file, {
            preview: URL.createObjectURL(file)
        })))
    }, [setFiles])
    const { getRootProps, getInputProps, isDragActive } = useDropzone({ onDrop })

我收到了

参数“acceptedFiles”隐式具有“any”类型

有问题的文件 PhotoWidgetDropzone.tsx

import { useCallback } from 'react'
import { useDropzone } from 'react-dropzone'
import { Header, Icon } from 'semantic-ui-react'

interface Props {
    setFiles: (files: any) => void;
}

    export default function PhotoWidgetDropzone({setFiles}: Props) {
        const dzStyles = {
            border: 'dashed 3px #eee',
            borderColor: '#eee',
            borderRadius: '5px',
            paddingTop: '30px',
            textAlign: 'center' as 'center',
            height: 200
        }
    
        const dzActive = {
            borderColor: 'green'
        }
    
        const onDrop = useCallback(acceptedFiles  => {
            setFiles(acceptedFiles.map((file: any) => Object.assign(file, {
                preview: URL.createObjectURL(file)
            })))
        }, [setFiles])
        const { getRootProps, getInputProps, isDragActive } = useDropzone({ onDrop })
    
       
    
        return (
            <div {...getRootProps()} style={isDragActive ? {...dzStyles, ...dzActive} : dzStyles} >
                <input {...getInputProps()} />  
                <Icon name='upload' size='huge' />
                <Header content='Drop image here' />
            </div>
        )
    }

要修复参数“acceptedFiles”隐式具有“any”类型警告，只需从

react-dropzone

导入：

import { FileWithPath, useDropzone } from 'react-dropzone'

并添加类型 FileWithPath[]:

const onDrop = useCallback(acceptedFiles: FileWithPath[]  => {
    setFiles(acceptedFiles.map((file: FileWithPath) => Object.assign(file, {
        preview: URL.createObjectURL(file)
    })))
}, [setFiles])
