uniapp小程序图片上传功能效果预览

一、template 页面结构

javascript"><view class="upload-box">
	<view class="upload-list">
		<view class="upload-item" v-for="(item,index) of fileList" :key='index'>
			<image class="img" src="static/czc/file-icon.png"
				mode="">
			</image>
			<view class="name">
				{{item.fileName||''}}
			</view>
			<view class="close-icon" @click="onDelete(index)">
				<uni-icons type="closeempty" size="14" color="#999"></uni-icons>
			</view>
		</view>
	</view>
	<view class="upload-img" v-if="fileList.length<6">
		<image class="upload-icon" @click="onClick"
			src="https://yjzx.netda.gov.cn:18188/static/czc/upload-icon.png" mode="">
		</image>

	</view>
</view>

二、js部分

javascript">//data:
fileList: [],

//methods方法
onDelete(index){//删除方法
	this.fileList.splice(index,1)
},
maskClick() {},
onClick() {
	uni.chooseImage({
		count: 6 - this.fileList.length, //最大六张
		sizeType: ['original', 'compressed'], //可以指定是原图还是压缩图，默认二者都有
		sourceType: ['album', 'camera'],//相册、相机选择  默认二者都有
		success: (chooseImageRes) => {
			console.log(chooseImageRes)
			const tempFilePaths = chooseImageRes.tempFilePaths;
			if(tempFilePaths){  //图片的本地文件路径列表
				for(let i=0;i<tempFilePaths.length;i++){
					uni.uploadFile({
						header: {
							Authorization:this.token //接口需要登录传 token
						},
						url:'/file/loadUploadFile', //仅为示例，非真实的接口地址
						filePath: tempFilePaths[i],
						name: 'file',
						formData: {},
						success: (res) => {
							console.log(res);
							const obj = JSON.parse(res.data)  //上传结果
						
						},
						fail: (err) => {
							console.log(err)
						}
					});
				}
			}

		}
	});
},
