使用uview上传图片功能

效果如下图所示：

完整代码如下图所示：

<template>
	<view>
		<!-- 表单上传组件 -->
		<u-form-item :label="label" borderBottom ref="item1" :label-width="labelWidth">
                    <u-upload
                            :fileList="fileList1"
                            @afterRead="afterRead"
                            @delete="deletePic"
                            name="1"
                            multiple
                            :maxCount="10"
                    ></u-upload>
		</u-form-item>
		
	</view>
</template>

<script>
	// 引入接口文件
	import { uploadPhoto } from '@/request/api.js'
	export default {
		data() {
			return {
				showselectPopup:false,
				fileList1:[],
			}
		},
		props:{
			label:{
				type:String,
				required: true
			},
			labelWidth:{
				type:Number,
				default: 80
			},
			// 选择其默认值
			selectedData:{
				type:String,

			},
		},
		created() {
			
		},
		methods: {
			// 删除图片
			deletePic(event) {
				this[`fileList${event.name}`].splice(event.index, 1)
			},
			// 新增图片
			async afterRead(event) {
				// 当设置 multiple 为 true 时, file 为数组格式，否则为对象格式
				let lists = [].concat(event.file)
				let fileListLen = this[`fileList${event.name}`].length
				lists.map((item) => {
					this[`fileList${event.name}`].push({
						...item,
						status: 'uploading',
						message: '上传中'
					})
				})
				for (let i = 0; i < lists.length; i++) {
					const result = await this.uploadFilePromise(lists[i].url)
					let item = this[`fileList${event.name}`][fileListLen]
					this[`fileList${event.name}`].splice(fileListLen, 1, Object.assign(item, {
						status: 'success',
						message: '',
						url: result
					}))
					fileListLen++
				}
			},
			uploadFilePromise(url) {
				return new Promise((resolve, reject) => {
					let a = uni.uploadFile({
						url: 'https://test*********', // 仅为示例，非真实的接口地址
						filePath: url,
						name: 'file',
						formData: {
							user: 'test'
						},
						success: (res) => {
							setTimeout(() => {
								resolve(res.data.data)
							}, 1000)
						}
					});
				})
			},
		}

只需要修改请求地址，即可用。
