ColdFusion 9中文件上传的脚本函数

ColdFusion 9 中是否有与 cffile action="upload" 等效的 cfscript？查了一下文档，好像没有。

[更新] 这是9.0.1更新中添加的http://help.adobe.com/en_US/ColdFusion/9.0/CFMLRef/WSd160b5fdf5100e8f36f73035129d9e70a92-8000.html

您可以使用用户定义的函数轻松地抽象它。

<cffunction name="fileuploader">
    <cfargument name="formfield" required="yes" hint="form field that contains the uploaded file">
    <cfargument name="dest" required="yes" hint="folder to save file. relative to web root">
    <cfargument name="conflict" required="no" type="string" default="MakeUnique">
    <cfargument name="mimeTypesList" required="no" type="string" hint="mime types allowed to be uploaded" default="image/jpg,image/jpeg,image/gif,image/png,application/pdf,application/excel,application/vnd.openxmlformats-officedocument.spreadsheetml.sheet,application/msword,application/vnd.openxmlformats-officedocument.wordprocessingml.document,application/vnd.ms-powerpoint,application/vnd.openxmlformats-officedocument.presentationml.presentation,application/vnd.ms-excel,image/pjpeg">

    <cffile action="upload" fileField="#arguments.formField#" destination="#arguments.dest#" accept="#arguments.mimeTypesList#" nameConflict="#arguments.conflict#">

    <cfreturn cffile>
</cffunction>

然后在cfscript中使用它：

<cfscript>
    // NOTE: because of how cffile works, put the form field with the file in quotes.
    result = fileUploader("FORM.myfield", myDestPath);
    WriteOutput(result.fileWasSaved);
</cfscript>

注意：我会非常小心地重命名此函数，以防 Adob​​e 将来确实包含此功能。
