转换pdf速度慢

转换pdf的时候速度很慢，能不能优化一下速度呀

kkFileView可以转变为直接读取本地文件吗?

自己配置了域名用于访问预览服务，但是PPT的预览有问题

如图，获取PPT每页图片时应该使用我的域名；

使用localhost本地启动是可以预览的，请问是我的nginx配置问题吗？

如何关闭屏幕中间的触摸按钮?

如题, 因为这个按钮占地面积太大了, 手机端尤为明显.

而且平时只需要用一种就可以了. 哪位大佬知道帮忙告知下! 感谢感谢!~

有人可以说明一下怎么配置https访问吗？

文件名的获取没有考虑到特殊字符的问题

1 +1.txt 像这样的文档就会导致文件无法预览

小白求教

怎么导入这个com.yudianbank:jodconverter:jar包，不知道怎么mvn install,希望能详细告知一下，我也申请加qq群了，qq号是1075651441，望通过

doc 和docx 打不开，其他xls、ppt都可以打开，是什么问题？

doc文档本身是没有问题的，预览的时候就有问题

最新版编译打包。jdk8

控制台错误 日志如下

有没有可能实现cdn加速功能？

不知道对文件预览的支持是服务端还是客户端处理的，有没有可能支持cdn服务器的支持？
或者预览页面有没有可能cdn加速？毕竟文件如果全走自己的服务器，在公网上成本会非常之高。

用网关做映射

你好， 我打算用网关做一下转发， 如: http://10.0.126.36:8080/preview?url=, 但在前端调用的时候都会跳转到实际地址下，如：http://10.0.126.37:8012/index
请问这个有什么办法可以解决吗?

spring.cloud.gateway.routes[4].id = file-preview
spring.cloud.gateway.routes[4].uri = http://10.0.126.37:8012/onlinePreview
spring.cloud.gateway.routes[4].predicates[0] = Path=/preview**
spring.cloud.gateway.routes[4].filters[0] = StripPrefix=1

在Windows10中启动了kkFileView-2.1.2版本，预览word报错

预览的地址是：http://127.0.0.1:8012/onlinePreview?url=http%3A%2F%2Fkelan.nat300.top%2Fprofile%2Favatar%2F2019%2F11%2F08%2F123456.doc

发现kkFileView项目中存在REDos漏洞

您好：
我是360代码卫士团队的工作人员，我们在开源代码检测的项目中发现REDos漏洞，如下图

inputFilePath参数是可控的，当值为".aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.(a+)+$"
这样类似的值时，会造成服务器拒绝服务。
建议使用replaceAll函数时不要让正则表达式可控

excle乱码问题

为什么我上传的excle预览的时候就乱码了

嗨 死全家的**群管理

你不是很牛逼吗？来删帖啊 你爹昵称你看不顺眼？

文件没有后缀的情况

我大概看了一下源码的实现，使用的是url解析文件后缀。其实很多时候文件没有后缀，包括下载以后。可否这样去实现呢，下载文件的时候通过文件头去验证文件类型(或者下载文件后，因为有些文件类型的文件头是一致的)。然后再用相应的视图展示。个人建议，望采纳

不用redis 可以吗?

怎么才能在手机上实现预览呢

demo是跑起来了，在电脑上是能实现预览效果，但是手机浏览器一打开的话就是下载，要是能直接预览就好了

**玩意

**管理员 快出来哦，你家里都死完了

多图片预览

部署后,其他单个文件预览都没有问题;
多图预览不成功;

新增多图片同时预览功能，接口如下：
var fileUrl =url1+"|"+"url2";//多文件使用“|”字符隔开
window.open('http://127.0.0.1:8012/picturesPreview?urls='+encodeURIComponent(fileUrl));

来啊 继续关

word文档里有图片好像预览不得

当excel稍微复杂一点，预览效果很差，很乱

当excel稍微宽一点，会出现折行，请问预览的时候能按实际宽度来吗？有滚动条的话也可以
我用的openoffice

找不到jar

你好，发现一个依赖无法下载到
com.yudianbank
jodconverter

不好意思，发现这个包来自项目 jodconverter-cor

可以打印吗

能直接打印吗？

不同URL, 但文件名相同时, 会使用第一次解析的缓存内容

项目使用了kkFileView, 用户报上传文件后, 浏览的内容不对.
检查发现是用户删除了附件, 然后重新上传新的附件, 文件名称是相同的. 项目每个上传文件的URL都是唯一的.

确定从项目下载的内容是正确的, 检查发现是kkFileView的缓存数据时按文件名建立目录的, 所以会导致浏览内容是其他URL的.

解决方法有:
1.修改项目附件URL的文件名, 增加唯一ID, 比如 产品销售报表_123456789.xlsx
2.修改kkFileView的缓存目录名称, 使用 MD5(url)+产品销售报表_123456789.xlsx

OfficeFilePreviewImpl.java

String md5 = DigestUtils.md5DigestAsHex(decodedUrl.getBytes(StandardCharsets.UTF_8));

String md5 = DigestUtils.md5DigestAsHex(decodedUrl.getBytes(StandardCharsets.UTF_8));
String fileName = md5 + "_" + fileAttribute.getName();

docker 部署，kkFileView 看视频文件有问题？

url 流文件预览模式，当是视频MP4的时候，有声音播放，可是画面没有显示。
我需要做一些配置吗？
