Question

我在Grails中使用插件上传器以方便上传。当我输入＆＃34; \＆＃34;反斜杠会导致错误。

<uploadr:add   name="Uplaoder" path="\tmp\uploadr\myFirstUploadr" direction="up" maxVisible="5" >

错误位于页面底部。

如果我将路径值更改为＆＃34; / example＆＃34;或类似的东西，这个错误不是原因，即它不是在页面加载时添加文件。

我正在使用spring security，所以我认为这可能有效但不确定如何或者是什么？

非常感谢任何帮助。

我收到以下错误

Answer 1

我找到了解决方案，导致错误的原因是反斜杠是一个转义字符，我正在开发Windows。

我的解决方案

在config.groovy中添加

中的以下行

uploadr.defaultUploadPath="pathwhereyouwanttostore/folder"

然后在你的gsp中

<%@page expressionCodec="raw" %>
<%
    def downloads = grailsApplication.config.uploadr.defaultUploadPath
    def path1 = new File("${downloads}/folderName")
%>

请注意，上面的内容位于页面顶部，并且只是暂时的，因为这样做是不好的做法，path1应该由您的控制器传入。

这是uplaodr然后

   <div class="col-md-6">
                <uploadr:add name="Upload" path="${path1}" maxSize="52428800" />
            </div>

文件路径导致Grails中的错误
