在ColdFusion中导出到Excel

Question

我使用cfhttp发布了一些输入到url中，并期望以xls文件的形式下载一些数据。我正在尝试使用cffile ="write“获取数据，但这不起作用。有没有人能建议我们该怎么做。下面是代码

<cfhttp url="#Baseurl#" method="post" result="ExportToExcelresult" redirect="no" resolveurl="true">
    <cfhttpparam type="header" name="REFERER" value="#Baseurl#" >
    <cfhttpparam type="header" name="Cache-Control" value="no-cache">
    <cfhttpparam type="header" name="Content-Type" value="application/x-www-form-urlencoded">
    <cfhttpparam type="header" name="Connection" value="keep-alive" >

    <cfhttpparam type="header" name="cookie" value="TestCookie=;" encoded="yes">

    <cfloop collection="#CookieList#" item="i">

    <cfloop collection="#PostDefaultCookieList#" item="i">

当我执行cfdump时，结果是

当我执行cfdump时，它给出了一些二进制数据。我肯定得到了一些数据，但不确定如何将数据提取到xls文件中

Answer 1

要将二进制数据写入文件，只需使用函数filewrite。在下面的代码片段中，我写入了一个临时文件，但如果您想永久存储该文件，则需要写入该文件。然后，我将文件读回到电子表格对象中，以验证写入是否如预期的那样工作。

<cfhttp url="http://example.com/test.cfm" result="ExportToExcelresult">
</cfhttp>
<cfscript>
    //Replace with the file path where you want to permanently store the file
    yourFileLocation = getTempFile(getTempDirectory() ,"xls");

    //Save to file system
    filewrite(yourFileLocation, ExportToExcelresult.filecontent.toByteArray());

    //Not needed. Only verifying there is a spreadsheet written to the file location
    writeOutput("Is spreadsheet: " & isSpreadsheetFile(yourFileLocation));

    //You will not be working with a temp file. Do not delete it.
    fileDelete(yourFileLocation);
</cfscript>
