ASPupload 'if Not File Is Nothing' 始终 returns 错误

Question

使用Persits ASPupload component上传和处理文件（经典ASP）。

正在通过 jQuery ajax 表单上传文件。

我运行遇到了一个奇怪的情况，习惯测试 if Not File Is Nothing Then 总是 returns false 即使文件已经上传（我可以看到它在服务器上）。

这是我的 jQuery 代码：

    var hiddenSignature = $("#hiddenSignature").val();

    var formData = new FormData();

    formData.append('closingPic', $('#closingPic')[0].files[0]);
    formData.append('hiddenSignature',hiddenSignature);

    $.ajax({ 

        url: "ajax_tickets_file.asp?action=cost", 
        type: "POST", 
        enctype: 'multipart/form-data',
        contentType: false,
        processData: false,     
        data: formData, 

        beforeSend: function() {
            ...
        },
        success: function(msg) { 
            ...
       }
    });

这是 ajax_tickets_file.asp 上的服务器端代码：

   Set objUpload = Server.CreateObject("Persits.Upload.1")

    With objUpload

       .CodePage = 65001
       .OverwriteFiles = False

       Set file = .Files("closingPic")

       .SaveVirtual defaultUploadsFolder  // a file is indeed saved on the server, at the correct location 
       response.write " saved  "

       if Not file Is Nothing Then
            response.write “we have a file” 
        else
             response.write "no file"   //  this is what I get
        end if

因此，如前所述，我打印了“无文件”。

怎么会这样？

谢谢

H/T 感谢 Persits ASPupload 的所有者帮助我

代码应该是：

   .CodePage = 65001
   .OverwriteFiles = False

   //these 2 lines should be in reversed order: 'save' before 'set file'
   .SaveVirtual defaultUploadsFolder   
   Set file = .Files("closingPic")

ASPupload 'if Not File Is Nothing' 始终 returns 错误

ASPupload 'if Not File Is Nothing' always returns false
