kkFileView 预览文件报错：Whitelabel Error Page

拉取docker镜像和运行代码 docker pull keking/kkfileview:4.1.0 docker run -it -p 8012:8012 keking/kkfileview:4.1.0 然后在cloudreve中预览时显示：以及Java版本这是什么原因呢，求解决！

看情况应该是url必须带有文件类型后缀，不然不行,

https://gitee.com/kekingcn/file-online-preview/wikis/pages?sort_id=1504450&doc_id=106093 文档上说明了下，url后面加个fullfilename就可以了

var originUrl = 'http://127.0.0.1:8080/filedownload?fileId=1'; //要预览文件的访问地址 var previewUrl = originUrl + '&fullfilename=test.txt' window.open('http://127.0.0.1:8012/onlinePreview?url='+encodeURIComponent(previewUrl));
