pdfView 代码

<template>

			title="pdf预览"
			backgroundColor="#1677FF"
			height="88rpx"
			color="#fff"
			:border="false"
			safeAreaInsetTop></uni-nav-bar>

	</view>
</template>
 
<script>
	export default {
		data() {
			return {
				pdfUrl:'',
        // 方法一的预览路径，注意写法，文件命名可以自定义，具体看自己，但是参数格式不要错了
				viewerUrl: '/static/html/web/viewer.html?file='
			};
		},
		onLoad(options) {
      console.log(options)
      // pdf预览路径拼接，options是请求后端路径的页面值传参的
			this.pdfUrl = this.viewerUrl + options.pdfUrl
			console.log(this.pdfUrl)
		},
		methods:{
			back2Index(){
				uni.navigateBack()
			},
		}
	}
