			width: {
				type: Number,
				default: 60
			},
			height: {
				type: Number,
				default: 60
			},
			maxCount: { // 限制上传数量
				type: Number,
				default: 1
			},
			multiple: { // 是否开启图片多选
				type: Boolean,
				default: false
			},
			list: { // 图片列表
				type: Array,
				default: []
			},
			previewFullImage: { // 文件预览
				type: Boolean,
				default: true
			},
			accept: { // 上传类型 all | media | image | file | video
				type: String,
				default: image
			}
		},
		data() {
			return {
				fileList: []
			};
		},
		mounted() {
			this.fileList = this.list;
		},
		methods: {
			/**
			 * 删除图片
			 * @param {Object} event
			 */
			deletePic(event) {
				this.fileList.splice(event.index, 1)

				let lists = [].concat(event.file)
				let fileListLen =this.fileList.length
				lists.map((item) => {
					this.fileList.push({
						...item,
						status: 'uploading',
						message: '上传中...'

使用

<view>
	<uploadFile :list="imgList">uploadFile>

import uploadFile from '@/components/uploadFile/uploadFile.vue'

export default {
		components: {
			uploadFile
		},
		data() {
			return {
				imgList: [{ url: 'https://cdn.uviewui.com/uview/swiper/1.jpg' }] // test 根据业务处理
