我正在编写一个图像处理脚本来创建服务器上已经存在的图像的较小缩略图。

我需要搜索的目录结构如下：

Content
    -Att1
        -image1
            -imgA1_1.png
            -imgA1_1_large.png
        -image2
            -imgA1_2.png
            -imgA2_large.png
        -image3
            -imgA1_3.png
            -imgA1_3_large.png
    -Att2
        -image1
            -imgA2_1.png
            -imgA2_1_large.png
        -image2
            -imgA2_2.png
            -imgA2_2_large.png
        -image3
            -imgA2_3.png
            -imgA2_3_large.png
    -Att3
        -image1
            -imgA3_1.png
            -imgA3_1_large.png
        -image2
            -imgA3_2.png
            -imgA3_2_large.png
        -image3
            -imgA3_3.png
            -imgA3_3_large.png

etc...

所以我想要的是能够遍历上面显示的所有图像，如果该图像的尺寸超过 500-500，则创建一个 100-100 的缩略图。

有没有办法在不遍历每个目录的情况下做到这一点？

cfdirectory具有递归属性。这将遍历所有文件夹，但不需要您编写代码来遍历所有文件夹

<cfdirectory directory="yourDirectory" recurse="yes">

如果您正在处理非常大的目录，cfdi​​recotry 最终会非常慢。这是一个使用我编写的 java 的函数，因为我们有一些包含 1000 张图像的目录。它会查看并为您的所有文件创建查询结果，并且速度更快

<cffunction name="getDirectorylisting" returntype="query" output="true">
        <cfargument name="dirName" type="string" required="true" />
        <cfargument name="recurse" type="boolean" default="false" required="false" />
        <cfargument name="dirInfo1" type="query" default="#queryNew('datelastmodified,name,size,type,directory,hidden,pathname')#">
            <cfscript>
                var thisFile = '';
                var listFiles = '';
                var pathToParse = trim(dirName);

                var thisPath = '';
                var relPath = '';
                var theFileObj = '';
                var isDir = '';
                var isFile = '';
                var thisSize = '';
                var lastModified = '';
                var isHidden = '';
                var theType = '';

                if (left(dirName,2) == 'c:' || left(dirName,2) == 'd:' || left(dirName,2) == 'e:' || left(dirName,2) == '\\'){
                    //do nothing path is already absolute
                } else {
                    pathToParse = expandPath(pathToparse);

                if(right(pathToParse,1) == '/' || right(pathToParse,1) == '\'){pathToParse = left(pathToParse,len(pathToParse)-1);}
                if(right(dirName,1) == '/' || right(dirName,1) == '\'){dirName = left(dirName,len(dirName)-1);}
                if (directoryExists(pathToParse)){
