Vbs 脚本写异步上传

VBS (Visual Basic Scripting Edition) 是一种早期的Windows脚本语言,主要用于自动化任务和网页脚本编写。在VBS中,处理文件上传通常不会直接支持异步操作,因为VBS本身并不支持HTML表单的AJAX(Asynchronous JavaScript and XML)请求。不过,你可以通过创建定时器或者轮询的方式模拟异步效果。
下面是一个简单的示例,说明如何使用VBS编写同步上传文件到服务器的过程:
```vbscript
Option Explicit
Dim fso, file, http
Set fso = CreateObject("Scripting.FileSystemObject")
Set file = fso.OpenTextFile("c:\path\to\file.txt", 1)
Set http = CreateObject("MSXML2.ServerXMLHTTP")
http.Open "POST", "http://yourserver.com/upload.php", False '同步POST请求
http.setRequestHeader "Content-Type", "text/plain; charset=utf-8"
http.send file.ReadAll()
If http.Status = 200 Then
WScript.Echo "Upload successful: " & http.responseText
Else
WScript.Echo "Error uploading: " & http.statusText
End If
file.Close
Set file = Nothing
Set http = Nothing
Set fso = Nothing
```
如果需要模拟异步,可以设置一个定时器在一段时间后检查上传结果,但这不是真正的异步上传,而是客户端轮询服务器的状态。对于现代Web应用,推荐使用jQuery、axios等前端库配合Node.js或ASP.NET等后台技术来实现真正的异步上传。
