kkFileView对接svn服务完成文件在线预览功能

1.需求:

之前在公司内部搭建了svn服务器,给部门存放文档、视频,做成了一个文档服务器来用,随着视频文件太大,每次下载太慢

需要把文件在线打开查看

2.解决:

kkFileView

https://kkfileview.keking.cn/zh-cn/index.html

kkFileView为文件文档在线预览解决方案,该项目使用流行的spring boot搭建,易上手和部署,基本支持主流办公文档的在线预览,如doc,docx,xls,xlsx,ppt,pptx,pdf,txt,zip,rar,图片,视频,音频等等

我之前写过的svn部署文档 https://www.cnblogs.com/wang3680/p/dc92818c4cb50701dbc42eef5e8a2482.html


 

kkFileView无法适配svn服务,需要开发svn客户端完成svn服务器文件的checkout操作

3.改造kkFileView适配svn服务

我用的版本是4.0.0 GitHub地址 https://github.com/kekingcn/kkFileView

下载源码,导入到idea中

    主要是修改这段代码,增加svn类型的判断和工具类的使用

  • 使用方法如下:a.html
  • <!DOCTYPE html>
    
    <html lang="en">
    <head>
        <title>kkFileView演示首页</title>
    </head>
    
    <body>
    <div>
    
    </div>  
    <script type="text/javascript" src="https://cdn.jsdelivr.net/npm/js-base64@3.6.0/base64.min.js"></script>
    <script>
       var url = 'https://127.0.0.1/svn/业务学习资料/资料整理文档/JAVA学习/JAVA开发工具idea的使用01-王少帅.mp4';
       var pre_url = url + '?url.type=svn&svn.username=wangshaoshuai&svn.password=123456';
       window.open('http://127.0.0.1:8012/onlinePreview?url='+encodeURIComponent(Base64.encode(pre_url)));
    </script> 
    </body>
    </html>
    1    var url = 'https://127.0.0.1/svn/业务学习资料/资料整理文档/JAVA学习/JAVA开发工具idea的使用01-王少帅.mp4';
    2    var pre_url = url + '?url.type=svn&svn.username=wangshaoshuai&svn.password=123456';
    3    window.open('http://127.0.0.1:8012/onlinePreview?url='+encodeURIComponent(Base64.encode(pre_url)));

    主要是这段代码,即可加入到svn列表显示的服务里面会弹窗跳转一个新的预览页面


4.测试验证

  • idea下面启动服务
  •  

     用浏览器打开a.html
