ASPupload'if Not File Is Nothing'总是返回false。

Question

使用 坚持ASPupload组件 来上传和处理文件（经典ASP）。

文件是通过一个jQuery的ajax表单上传的。

我遇到了一个奇怪的情况，习惯性的测试 if Not File Is Nothing Then 总是返回 false 即使文件肯定已经被上传了（我在服务器上可以看到它）。

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) { 
            ...
       }
    });

这是服务器端的代码 ajax_tickets_file.asp。:

   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，我得到 "无文件 "的打印。

怎么会出现这种情况？

谅谅

感谢Persits ASPupload的主人帮助我。

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")
