微信小程序加载在线PDF，并禁用下载

7月前 作者：Dickence 分类：Toy博客 阅读(27) 违法举报

这篇具有很好参考价值的文章主要介绍了微信小程序加载在线PDF，并禁用下载。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

微信小程序本身不支持屏蔽下载按钮加载在线pdf。因此，需要通过其它方式进行加载。

在这里，使用当前最新版的pdf.js 3.0+，点击跳转至下载地址

1、修改View.html

下载后，可以屏蔽下载按钮，修改view.html如下：

</html>

2、修改view.js

如果需要修改以文件名做为页面的Title，需要修改view.js，屏蔽掉设置document.title的代码

3、在Nginx中发布该程序以及相应的pdf文件

设置nginx.conf：

    server {
  	listen 2000;
        listen [::]:2000;
  	server_name _;
  	root /home/data/file-db;
	index /html/web/viewer.html;
  	location / { 
    	    autoindex off;
    	    autoindex_exact_size off;
    	    autoindex_localtime off;
  	}
    }

把pdf文件放置在 /home/data/file-db中（含子目录）

把pdf.js相关的web和build文件夹放在/home/data/file-db/html中。

使用地址：http://<<your-ip>>:2000/html/web/viewer.html?file=http%3A%2F%2F171.84.0.40%3A2000%2Fstandard%2Fpolicy%2F10267ad6-2c0a-4056-b97a-6b158cf55698.pdf

“?”后的部分为encodeURIcomponent()后的url，端口号需要与本服务url相同文章来源地址https://www.toymoban.com/news/detail-485172.html

4、小程序中使用该服务

<template>
    <view>
        <web-view :src="src"></web-view>
    </view>
</template>

<script>
export default {
data: function (){
   return {
     src: null
   };
},
onLoad(options) {
    this.src = 'http://171.84.0.40:20000/html/web/viewer.html?file=' + encodeURIComponent(options.url);
  }
}
</script>
