生成多个文件,将它们添加到zip中,然后将zip文件作为文件下载发送。

我有一个生成多个电子表格对象的cfm页面,现在如果我尝试发送文件进行下载,只会将下一个生成的电子表格文件作为下载文件发送。

有没有办法将这些文件写入zip并将zip文件作为下载文件发送?

这是我现有的逻辑:

for(VARIABLES.fileNumber = 0; VARIABLES.fileNumber  < VARIABLES.maxFiles; VARIABLES.fileNumber = VARIABLES.fileNumber + 1)
{
   /* code to create Spreadsheet here */




    VARIABLES.context = getPageContext();
    VARIABLES.context.setFlushOutput(true); 

    VARIABLES.response = VARIABLES.context.getResponse().getResponse();
    VARIABLES.response.reset();
    VARIABLES.response.setContentType("application/msexcel");   
    VARIABLES.response.setContentLength(len(SpreadsheetReadBinary(VARIABLES.suppItemSpreadSheetObj)));       
    VARIABLES.response.setHeader("Content-Disposition","attachment;filename=MyComplianceStatusFile#VARIABLES.fileNumber#Of#VARIABLES.maxFiles#.xls");

    VARIABLES.out = response.getOutputStream();     
    VARIABLES.out.write(SpreadsheetReadBinary(VARIABLES.suppItemSpreadSheetObj));       


    VARIABLES.out.flush();      
    VARIABLES.out.close();  
  }

现在,通过这种方式,我只获得了生成的最后一个电子表格。有没有办法让所有生成的电子表格一个接一个或者可能是拉链?

是的,有:<cfzip>。在文档中有一个用法示例,但我会在这里重复,所以我不会因为基本上说“RTFM”而受到打击:

<!--- This example shows how to zip the directory "c:\temp" into the ZIP file "e:\work\abc.zip". ---> 
<cfzip file="e:\work\abc.zip" source="c:\temp"> 

<!--- This example shows how to zip all the class files in a directory and add a subdirectory named "classes" to the JAR file entry name. ---> 
<cfzip file="e:\work\util.jar" action="zip" source="c:\src\util\" prefix="classes" filter="*.class"> 

<!---This example shows how to zip all of the log files in the ColdFusion directory and create a subdirectory called exception where zipped files are archived. 
<cfzip file="c:\zipTest\log2.zip" action="zip" source="c:\ColdFusion\" prefix="exception" filter="*.log"> 

<!--- This example shows how to overwrite all of the content of a ZIP file with the entries specified in the source. ---> 
<cfzip file="c:\currentApp.zip" source="c:\myApp\work" overwrite="yes">
