接入说明
如果你的项目需要接入文件预览项目,达到对docx、excel、ppt、jpg等文件的预览效果,那么通过在你的项目中加入下面的代码就可以成功实现:
var url = 'http://127.0.0.1:8080/file/test.txt'; //要预览文件的访问地址
window.open('http://127.0.0.1:8012/onlinePreview?url='+encodeURIComponent(base64Encode(url)));
新增多图片同时预览功能,接口如下:
var fileUrl =url1+'|'+url2;//多url使用'|'字符隔开
window.open('http://127.0.0.1:8012/picturesPreview?urls='+encodeURIComponent(base64Encode(fileUrl)));
输入下载地址预览文件
预览测试
FreeMarker template error (DEBUG mode; use RETHROW in production!):
The following has evaluated to null or missing:
==> fileUploadDisable [in template "index.ftl" at line 99, column 18]
----
Tip: If the failing expression is known to legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing#if>. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??
