1.下载pdf.js文件Getting Started (mozilla.github.io)
2.将下载的文件放进uniapp项目中
3.创建预览页面
代码：
<template>
<view>
<web-view :src="allUrl"></web-view>
</view>
</template>
<script>
import request from "@/utils/request.js";
export default {
data() {
return {
viewerUrl: '/static/web/viewer.html',
allUrl: ''
}
},
onLoad(e) {
if (e.path.indexOf('http') == -1) {
let fileUrl =
request.BASE_URL + '/sysFileInfo/public/preview?fileId=' + e.path.split('=')[1]
console.log('fileUrl----', fileUrl, request.BASE_URL + '/sysFileInfo/public/preview?fileId=' + e.path
.split('=')[1])
// let fileUrl = encodeURIComponent(
// "/static/web/compressed.tracemonkey-pldi-09.pdf")
this.allUrl = this.viewerUrl + '?file=' + fileUrl; // encodeURIComponent 函数可把字符串作为 URI 组件进行编码;
console.log(this.allUrl)
} else {
console.log('e.path', e.path)
this.allUrl = this.viewerUrl + '?file=' + encodeURIComponent(e.path)
console.log(this.pdfUrl)
}
}
}
</script>
最后附上预览效果：
