微信小程序实现上传照片功能

案例：

html:

<view class="zhengjianCont fontSize30" style="margin-bottom: 40rpx;">
			<view class="kuai">
				<image binderror="imageOnloadError" bind:tap="upladPhoto" data-params="businessLicense" data-name="zhengZhaoGuanLi" class="kuaiImg" src="{{businessLicense?businessLicense:'/static/image.png'}}"></image>
				<view style="margin-top: 10rpx;">营业执照照片</view>
			</view>
		</view>

js:

		data: {
		businessLicense: '',
	},
	upladPhoto(e) {
		let that = this;
		// 定义图片存储路径，增加年月文件夹分类
		let folder = e.currentTarget.dataset.name + "/" + TIME.getYearMonth()
		this.ossPromise(folder, e.currentTarget.dataset.params).then(resUrl => {
			that.setData({
				[e.currentTarget.dataset.params + 'OSS']: resUrl.path
			})
		}).catch(errr => {
			console.log(errr)
			wx.hideLoading()
			return false
		})
	},
