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

   <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>
