Question

我处于用户点击下载按钮时调用流连接的情况。提交下载按钮时，将在ASP中调用一个函数，其中下载代码在文件BD_Test1.txt上执行。此文本文件的内容只是TEST 1。

文件正常下载，但打开时，所有HTML代码都在文本文件中。

HTML代码

<html>

<head>
    <title>Bulk Download Zipper</title>
    <!--#include file="BD_Download.asp"-->
</head>

<body>
    <center><h1>Bulk Download Zipper</h1></center>

    <br><br>

    <p>Please click "Download" to zip the files.</p>

    <form method="post">
        <br><input type = "submit" name="zipFile" value = "Download"/><br>
    </form>

    <br><br>

    <%
    If (Request.Form("zipFile") <> "") Then
        Call downloadFile()
    End If
    %>
</body>

</html>

ASP代码

<%
Function downloadFile()
    Dim download_File, download_Remove, download_Autoremove

    Set download_File = Server.CreateObject("ADODB.Stream")
    download_File.Type = 1
    download_File.Open
    download_File.LoadFromFile("E:\inetpub\wwwroot\cdc\wnyaccc_erie_niagara_trd-2\youkergav\BulkDownload\resumes\BD_Test1.txt")

    Response.AddHeader "Content-Transfer-Encoding", "binary" 
    Response.AddHeader "Content-Description", "File Transfer" 
    Response.AddHeader "Content-Disposition", "attachment; filename=Resumes.txt"
    Response.CharSet = "UTF-8"
    Response.ContentType = "text/plain"
    Response.BinaryWrite download_File.Read

    download_File.Close
    Set download_File = Nothing
End Function
%>

下载的文本文件的内容

<html>

<head>
    <title>Bulk Download Zipper</title>

</head>

<body>
    <center><h1>Bulk Download Zipper</h1></center>

    <br><br>

    <p>Please click "Download" to zip the files.</p>

    <form method="post">
        <br><input type = "submit" name="zipFile" value = "Download"/><br>
    </form>

    <br><br>

    TEST 1
</body>

</html>

如您所见，正在插入文本文件的内容，其中调用了downloadFile()函数。是否有可能以这种方式使用流连接？

Answer 1

在页面已经开始提供给客户端后，您的downloadFile功能被称为。 ASP只是简单地注入你的函数的结果。您需要在POST上覆盖整个输出。在GET上输出html，并在POST上输出文本文件：

<% If (Request.Form("zipFile") <> "") Then Call downloadFile() Else%> <html> <head> <title>Bulk Download Zipper</title>  </head> <body> <center><h1>Bulk Download Zipper</h1></center> <br><br> <p>Please click "Download" to zip the files.</p> <form method="post"> <br><input type = "submit" name="zipFile" value = "Download"/><br> </form> <br><br> </body> </html> <% End If %>
