求解答

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。

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));

**管理员 快出来哦，你家里都死完了

后台代码是把压缩文件解压到上一级文件夹，但如果解压后的文件中还有其它压缩文件， 那再次预览里面这个文件时，会解压失败

xls文件转html没有乱码，但是在代码里面强转utf-8后中文乱码

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

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

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

$scope.openWin 这个方法在vue中怎么使用
$scope.openWin = function (fileUrl) {
var url = configuration.previewUrl + encodeURIComponent(fileUrl);
var winHeight = window.document.documentElement.clientHeight-10;
$window.open(url, "_blank", "height=" + winHeight
+ ",top=80,left=80,toolbar=no, menubar=no, scrollbars=yes, resizable=yes");
};

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

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!~

转换pdf的时候速度很慢，能不能优化一下速度呀

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？

我的调用代码：
``

    function viewMp4() {

        var originUrl = "http://192.168.0.230:8080/v1/AUTH_333104be5d78420e8491bd292afb9554/ljs/KBsPbah2TNSXEJ84tsy8?temp_url_sig=4e8279ef1727332ac87c7544f16261b13025013a&temp_url_expires=1573790594&filename=01%E8%AF%BE%E7%A8%8B%E7%BB%BC%E8%BF%B0.mp4";
        var previewUrl = originUrl + '&fullfilename=myxxxx.mp4';
        window.open('http://192.168.0.115:8012/onlinePreview?url='+encodeURIComponent(previewUrl));

    }

``

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

你不是很牛逼吗？来删帖啊 你爹昵称你看不顺眼？

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 pdfName = md5 + "_" + fileName.substring(0, fileName.lastIndexOf(".")) + "pdf";

CompressFilePreviewImpl.java

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

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

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

这个该如何解决？

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

不好意思，发现这个包来自项目 jodconverter-cor

谢谢

项目启动的时候正常、访问也正常，大概过了一两个小时后，再访问的话页面无法打开。并且日志报错。

动态ppt能转成动态的h5页面吗

1 +1.txt 像这样的文档就会导致文件无法预览

如果支持水印就更好了

能直接打印吗？

为什么我上传的excle预览的时候就乱码了

PPTX格式，如题，将Window下的字体拷贝过去了好像也不起作用，
参照CSDN的答疑来做的，结果还是乱码
https://blog.csdn.net/weixin_33716154/article/details/89565127

改成宋体就正常的，应该可以排除编码问题
