我正在使用的“纯 ASP”文件上传脚本给了我一个错误

Microsoft VBScript runtime error '800a0005'

Invalid procedure call or argument: 'MidB'

在这一行（包含文件 clsUpload.asp 的第 103 行）：

mstrDelimiter = MidB(mbinData, 1, InStrB(1, mbinData, CRLF) - 1)

当我在同一页面上结合文件上传和数据库上传脚本时。我认为这可能与类的实例化有关，并且我尝试在整个脚本中建立类，而不是将其设置为“无”并重新建立它，但这没有任何区别。有任何想法吗？

上传脚本工作正常，只要它们位于单独的页面上，由页面上的前两个表单分别发布（如下）。然而，第三种形式并不成功。非常感激！

（下面的完整代码）

注意：“clsUpload.asp”和“clsField.asp”文件太大，无法发布。但是，它们可以在这里找到： http ://www.codeguru.com/dbfiles/get_file/upload_files_without_com_v2.zip?id=19297&lbl=UPLOAD_FILES_WITHOUT_COM_V2_ZIP

表单页面如下：

 <H2>To Database</H2>
<FORM name="a" id="a" method="post" encType="multipart/form-data" action="ToDatabase.asp">
<INPUT type="File" name="File1">
<INPUT name="Submit" type="submit" value="Upload">
 </FORM>

<H2>To File System</H2>
<FORM name="b" id="b" method="post" encType="multipart/form-data" action="ToFileSystem.asp">
<INPUT type="File" name="File1">
<INPUT name="Submit" type="submit" value="Upload">
</FORM>


<H2>To Both Database and File System</H2>
<FORM name="c" id="c" method="post" encType="multipart/form-data" action="ToDatabaseAndFileSystem.asp">

问题出在 clsField.vbs 文件中

如果路径不包含“\”，则 FileName 字段保持空白：

我建议在 if 语句中添加一个 else 条件，如下所示：

    ' Parse File Name
    If Not InStrRev(pstrPath, "\") = 0 Then
        FileName = Mid(pstrPath, InStrRev(pstrPath, "\") + 1)
    else
        FileName = pstrPath
    End If

此行失败：

mstrDelimiter = MidB(mbinData, 1, InStrB(1, mbinData, CRLF) - 1)

可能的原因：

  • mbinData 长度为零
  • mbinData 不包含 CRLF
  • mbinData 以 CRLF 开头
  • 标识符 CRLF 不包含预期的字节序列

找出以上哪项在您的情况下是正确的，您会发现问题所在。
