`HttpOpenRequest`通常不是直接用于启动ASP(Asynchronous Page),而是用于HTTP请求的客户端编程,比如在VBA(Visual Basic for Applications)或某些自动化工具中。当你使用`HttpOpenRequest`时,你创建了一个HTTP请求对象,可以用来向ASP或其他web服务器发送数据。
以下是一个简单的例子,说明如何在VBA中使用`HttpOpenRequest`向ASP发起GET或POST请求:
```vba
Sub CallASPWithHttpOpenRequest()
Dim http As Object '假设已经导入了Microsoft.XMLHTTP60
Set http = CreateObject("MSXML2.XMLHTTP")
' URL of your ASP page
Dim aspUrl As String
aspUrl = "http://yourwebsite.com/youraspfile.asp"
' POST data (if any)
Dim postData As String
postData = "param1=value1¶m2=value2" '用URL Encode编码参数
' HTTP method (GET or POST)
If postData <> "" Then
http.Open "POST", aspUrl, True
http.setRequestHeader "Content-type", "application/x-www-form-urlencoded"
http.send postData
Else
http.Open "GET", aspUrl, True
http.Send
End If
' Check response
If http.Status = 200 Then
Debug.Print http.responseText ' 打印接收到的ASP响应
Else
MsgBox "Error: " & http.Status & " - " & http.statusText
End If
http.Close
End Sub
```
在这个例子中,`HttpOpenRequest`主要用于发送HTTP请求到指定的ASP页面,并可能携带POST数据。然后,ASP会处理这个请求,返回响应给客户端。
