在显示标准操作程序(SOP)的页面上工作,并允许非管理员以PDF文件下载SOP。客户决定不希望管理员只上传PDF文件,他们希望选择上传.doc和.docx文件。我需要下载链接来生成PDF。
现在上传的.doc / .docx或.pdf文件会显示为我希望使用Google Viewer时的样子。但是,当我尝试下载测试文件时,如果上传的文件是.doc / .docx,则无法打开。我已经看过这个了,我确定我想念一些愚蠢的东西。
我正在使用 cfdocumnet ,这是另一个问题的建议。
下载链接:
<cfoutput>
<li class="active">
<ahref="/files/SOP/SOP.pdf"
download="SOP.pdf" target="_blank">Download SOP</a>
</li>
</cfoutput>
检查管理员(变量在其他位置创建)和表单以上传文件:
<cfif isAdmin>
<h3>Upload New SOP</h3>
<cfparam name="form.fileUpload" default="">
<cftry>
<cffile action="upload"
fileField="fileUpload"
destination="#expandPath('.')#\files\SOP\"
accept="application/pdf,
application/msword,
application/vnd.openxmlformats-officedocument.wordprocessingml.document,
application/x-tika-msoffice"
nameconflict="OVERWRITE">
<cfset fileName=CFFILE.serverfile>
<cfdocument
format="PDF"
srcfile="#expandPath('.')#\files\SOP\#fileName#"
filename="#expandPath('.')#\files\SOP\SOP.pdf"
overwrite="YES">
</cfdocument>
<p>Thank you, your file has been uploaded.</p>
<cfoutput>#fileName#</cfoutput>
<form enctype="multipart/form-data" method="post">
<input type="file" name="fileUpload"/>
<input type="submit" name="submit" value="Upload File"/>
</form>
<cfcatch type="any">
<!--- file is not written to disk if error is thrown --->
<!--- prevent zero length files --->
<cfif FindNoCase("No data was received in the uploaded", cfcatch.message)>
<p>No data was received in the uploaded file.</p>
<!--- prevent invalid file types --->
<cfelseif FindNoCase("The MIME type or the Extension of the uploaded file", cfcatch.message)>
<p>Invalid file type. Please upload file as a PDF or Word Doc</p>
<!--- prevent empty form field --->
<cfelseif FindNoCase("did not contain a file.", cfcatch.message)>
<p>Please seclect a PDF to upload.</p>
<!---all other errors --->
<cfelse>
<p>Unhandled File Upload Error</p>
<cflog type="Error" file="#application.applicationname#_dcnsopupload_error" text="#cfcatch.Message# - #cfcatch.Detail#" />
<cfoutput>#cfcatch.Detail#</cfoutput>
</cfif>
</cfcatch>
</cftry>
</cfif>
另外,由于我希望将可下载的.pdf命名为“ SOP.pdf”,有没有一种方法可以在重命名并转换用户后删除用户上传的文件?只是服务器上没有30个不同的过时SOP文档。
答案 0 :(得分:2)
表单上传代码看起来错误。由于cfparam
,它可能试图在提交表单之前 进行上传/转换。删除cfparam
并使用structKeyExists()来验证文件字段是否已提交,然后再尝试对其进行处理。
首先尝试一个简化的示例,仅包含表单和上载代码(无错误处理)。
<!--- If file was uploaded, process it --->
<cfif structKeyExists(FORM, "fileUpload")>
<cffile action="upload"
fileField="fileUpload"
destination="#GetTempDirectory()#"
accept="application/pdf,application/msword,
application/vnd.openxmlformats-officedocument.wordprocessingml.document,
application/x-tika-msoffice"
nameconflict="makeunique">
<cfset savedFilePath = cffile.serverDirectory &"/"& cffile.serverFile>
<!---
more file validation here ...
--->
<!--- convert file --->
<cfdocument format="PDF"
srcfile="#savedFilePath#"
filename="#expandPath('.')#\files\SOP\SOP.pdf"
overwrite="YES">
</cfdocument>
<!--- cleanup temp file --->
<cfif fileExists(uploadedFile)>
<cfset fileDelete(uploadedFile)>
</cfif>
<!--- Otherwise, just display the form --->
<cfelse>
<form enctype="multipart/form-data" method="post">
<input type="file" name="fileUpload"/>
<input type="submit" name="submit" value="Upload File"/>
</form>
</cfif>
尽管有些陈旧,但有关保护文件上传的一些技巧仍然有效(例如,不将文件上传到Web根目录):
