Download JPG’s with ColdFusion from a Linux server
July 7th, 2006 英文
与Flex和Coldfusion案卷upload/下载component操作时我碰到一些好玩的Linux 和Windows file format的问题。Upload一些案卷没问题但是,除非你使用Coldfusion的缺省charset tag, Linux服务器的JPG就办不动。
XML:
-
<cffile action="read"
-
file="#folder#/#filename#" variable="fileData"/>
-
<cfcatch>
-
<cflog text="Invalid read #folder#/#filename#">
-
</cfcatch>
-
</cftry>
-
<cfif fileData NEQ ""><cfcontent reset="yes"><cfoutput>#fileData#</cfoutput></cfif>
用上述的代码会使JPG"不能用"。在tag内你必须设定"charset"。下面的代码有效。
XML:
-
<cffile action="read" charset="iso-8859-1"
-
file="#folder#/#filename#" variable="fileData"/>
-
<cfcatch>
-
<cflog text="Invalid read #folder#/#filename#">
-
</cfcatch>
-
</cftry>
-
<cfif fileData NEQ ""><cfcontent reset="yes"><cfoutput>#fileData#</cfoutput></cfif>
依靠服务器的缺省, 我认为还有别的办法。所以当你想从Linux 服务器,用ColdFusion下载二进制案卷时,要小心charset的问题。

Hello,
I’ve the same problem. When I upload a document (word, excel, …), the files seems to be uploaded correctly. But when I try to download it (using cffile tag), the file is corrupted (invalid charset I think).
Can you help me . Do you have found any solution ?
Thanks,
Ced

<cffile action=”read” charset=”iso-8859-1″ …
Worked for me, here is a list of all the valid charsets try them all:
* utf-8
* iso-8859-1
* windows-1252
* us-ascii
* shift_jis
* iso-2022-jp
* euc-jp
* euc-kr
* big5
* euc-cn
* utf-16
