Question

我也有阴影上传器并且在5个表单字段（在原始代码中添加2个）非常适用于exmple但是想要11，只要我添加一个额外字段我就会收到错误：

Request object error 'ASP 0104 : 80004005'
Operation not Allowed
/a20couk/includes/ShadowUploader.asp, line 56

这是我的额外代码，shadowuploader包含的内容保持不变：

<!-- #include file="../../includes/ShadowUploader.asp" -->
<%
Dim objUpload
If Request("action")="1" Then
    Set objUpload=New ShadowUpload
    If objUpload.GetError<>"" Then
        Response.Write("sorry, could not upload: "&objUpload.GetError)
    Else
        Response.Write("found "&objUpload.FileCount&" files...<br />")
        For x=0 To objUpload.FileCount-1
            Response.Write("file name: "&objUpload.File(x).FileName&"<br />")
            Response.Write("file type: "&objUpload.File(x).ContentType&"<br />")

Answer 1

在使用request.form集合后，不允许使用request.binaryread。

但你的

If Request("action")="1" Then

使用request.form集合，因为您没有使用request.querystring("action")。

之后你实例化上传器，这在第56行request.BinaryRead

中使用

Answer 2

正如this answer中所述，POST请求大小的默认限制是200KB - 对于Microsoft来说是典型的，如果超出限制，则会出现错误信息，这是非常有用的。

要修复此错误并允许更大的文件和/或更多文件，您需要更改IIS中的设置。

对于IIS 7.5（Windows 7的默认设置），首先选择该站点，然后双击＆＃34; ASP＆＃34;在IIS下：

现在写一个大于200000的数字作为＆＃34;最大请求实体主体限制＆＃34;在＆＃34;限制属性＆＃34;部分：（15728640是15 MB这是合理的限制）

点击＆＃34;申请＆＃34;在右侧边栏中，您已完成。快乐的节目！

任何人都可以帮我这个影子上传脚本？
