• 前端vue点击图片上传(带封装方法)

    第一种

    直接用，图片路径自己换一下

    <template>
	<view class="uPImg">
		<view class="Img">上传照片 :view>
		<view class="shangchuan">
			<view class="sc2" v-for="(item, index) in imgList" :key="index">
				<image class="del" @click="del(index)" src="../../../static/property/paymentUpload.png" mode="">
				image>
				<image class="Img3" :src="item" mode="">image>
			view>
			<view class="sc2" v-if="imgList.length < 3" @click="upload">
				<image class="sc3" src="../../../static/property/paymentUpload.png" mode="">image>
			view>
		view>
	view>
template>

<script>
	export default {
		data() {
			imgList: [],
		},
		methods {
			// 点击上传图片
			upload() {
					uni.chooseImage({
						count: 1, //默认9
						sizeType: ['original', 'compressed'], //可以指定是原图还是压缩图，默认二者都有
						sourceType: ['album'], //从相册选择
						loop: true,
						success: res => {
							console.log(res);
							if (res.tempFilePaths.length != 0) {
								this.imgList.push(res.tempFilePaths[0]);
							}
							console.log(JSON.stringify(res.tempFilePaths));
							var tempFilePaths = res.tempFilePaths;

							console.log(tempFilePaths);
							console.log(tempFilePaths[0]);
							uni.uploadFile({
								url: 'http://douzhuoqianshouba.xieenguoji.com/api/ajax/upload',
								filePath: tempFilePaths[0],
								name: 'file',
								success: uploadFileRes => {
									console.log('上传图片', JSON.parse(uploadFileRes.data));
								},
								fail(err) {
									console.log(err);
								}
							});
						}
					});
				},

				// // 删除图片
				del(index) {
					this.imgList.splice(index, 1);
					console.log(this.imgList);
				},
		}
	}

    第二种封装方法

    封装组件upload.vue

    直接用，图片路径自己换一下

    <template>
	<view>view>
template>

<script>
export default {
	data() {
		return {
			/*需要返回的图片*/
			imageList:[]
		};
	},
	onLoad() {},
	props:['num'],
	mounted() {
		this.chooseImageFunc();
	},
	methods: {
		
		/*打开相机或者相册，选择图片*/
		chooseImageFunc() {
			let self=this;
			uni.chooseImage({
				count: self.$props.num || 9, //默认9
				sizeType: ['original', 'compressed'], //可以指定是原图还是压缩图，默认二者都有
				sourceType: ['album', 'camera'], //从相册选择
				success: function(res) {
					self.uploadFile(res.tempFilePaths);
				},
				fail:function(res){
					self.$emit('getImgs',null);
				},
				complete:function(res){
					
				}
			});
		},
		
		/*上传图片*/
		uploadFile: function(tempList) {
			let self = this;
			let i = 0;
			let img_length=tempList.length;
			let params = {
				token: uni.getStorageSync('token'),
                app_id: self.getAppId()
			};
			uni.showLoading({
			    title: '图片上传中'
			});
			tempList.forEach(function(filePath, fileKey) {
				uni.uploadFile({
					url: self.websiteUrl + '/index.php?s=/api/file.upload/image',
					filePath: filePath,
					name: 'iFile',
					formData: params,
					success: function(res) {
						let result = typeof res.data === 'object' ? res.data : JSON.parse(res.data);
						if (result.code === 1) {
							self.imageList.push(result.data);
						}else{

						}
					},
					complete: function() {

    使用组件

    引入上面upload.vue

    <template>
