ColdFusion-需要遍历文件夹以从SQL查询中查找特定文件，并将其复制或压缩到临时文件夹

标签： sql coldfusion cffile cfdirectory cfzip

我试图遍历服务器上的文件夹以获取特定文件的列表，然后将这些文件复制到临时目录或压缩并复制到临时目录。但是我不确定如何做到这一点。 （仍然是ColdFusion的业余爱好者）

所以我在这里执行SQL查询，从特定的日期检索确切的附件：

<cfquery name="test" datasource="test" cachedwithin="#CreateTimeSpan(0,0,10,0)#" result="r">
SELECT Test.TestNum, Test1.Test1Date, TestReport.Attachment
FROM Test
INNER JOIN more SQL code here..
WHERE Test1.Test1Date >= '#daterangevariablehere#'
AND NOT more SQL code here as well..
ORDER BY Test.TestNum
</cfquery>

SQL Query与SQL Server Mgmt Studio中的SQL Query是正确的，它可以正确执行，甚至在我尝试执行cfdump之前，它还会显示我要获取的文件的正确列表。但是，当我尝试遍历它们以复制或压缩它们时，完全失败->空白页。

我试图：

<cfloop query="test">
<cfif test.recordcount gt 0>
<cfzip action="zip" file="#LocationOfwhereIwantTheEndResult" source="#WhereTheFolderWithTheAttachmentsReside#">
</cfzip>
</cfloop>

我什至尝试将其包装在上面的代码中：

<cfdirectory action="list" name="test" directory="#WhereTheFolderWithTheAttachmentsReside#"></cfdirectory>

旁注：为了安全和匿名起见，一些变量和代码是组成的。.但是我想展示我要完成的工作的结构，希望我可以清楚（！），否则请让我知道，我将提供更多详细信息。非常感谢您的帮助，我一直将头撞在墙上的墙上，觉得这可能是一件非常简单的事情。请帮忙！ ：）

在不知道实际值的情况下，听起来您的查询包含单个文件的绝对路径。一种选择是循环查询，并为每个文件添加一个cfzipparam。这是一个独立的示例，您可以适应。 （它使用CFML，因为这就是您的示例，但是，如果您熟悉脚本语法，请在上面的链接中查找基于cfscript的版本。）

CFML示例： 

<!--- For Demo only to simulate your database query --->
<cfset test = queryNew("Attachment"
            , "varchar"
            , [{Attachment="c:\path\to\fileA.png"}
                , {Attachment="c:\path\to\fileB.png"}
                , {Attachment="c:\path\to\fileC.png"}
            ])>

<cfzip action="zip" file="c:\path\to\TheNameYouWant.zip">
    <cfloop query="test">
        <!--- If Attachment only contains a file name (i.e. "someFileName.pdf") 
           use your variables to build a full path, i.e. "c:\path\to\someFileName.pdf" 
         --->
        <cfzipparam source="#Attachment#">
    </cfloop>
</cfzip>

CFScript示例 

<cfscript>
   test = queryNew("Attachment"
            , "varchar"
            , [{Attachment="c:\path\to\fileA.png"}
                , {Attachment="c:\path\to\fileB.png"}
                , {Attachment="c:\path\to\fileC.png"}
            ]);

    cfzip (action="zip", file="c:\path\to\TheNameYouWant.zip") {
        for (row in test) {
            cfzipparam (source=row.Attachment);
        }
    }
</cfscript>

简而言之，您不必发布实际路径。在大多数情况下，它还是无关紧要的；-)但是，请确实发布表示实际路径的硬编码值，而不是变量。原因是变量会留下很多悬而未决的问题，可以使用c:\path\to\fileA.pdf之类的虚拟路径轻松回答。在这种特定情况下，了解操作系统之类的东西，源是文件/目录还是相对/绝对路径，将帮助我们立即排除一些潜在问题。
