Domino中应用Ajax请求

1. 如何使用

Dim internet As New RemoteHTML()
Dim html As String
html = internet.GetHTTP("http://www.texasswede.com/deepsouth.command")

2.创建RemoteHTML类

Option Public
Option Declare

Class RemoteHTML
    Private httpObject As Variant
    Public httpStatus As Integer

    Public Sub New()
        Set httpObject = CreateObject("MSXML2.ServerXMLHTTP")
    End Sub

    Public Function GetHTTP(httpURL As String) As String
        Dim retries As Integer
        retries = 0     
        Do
            If retries>1 Then
                Sleep 1     ' After the two first calls, introduce a 1 second delay betwen each additional call
            End If
            retries = retries + 1   
            Call httpObject.open("GET", httpURL, False)
            Call httpObject.send()
            httpStatus = httpObject.Status
            If retries >= 10 Then
                httpStatus = 0  ' Timeout
            End If
        Loop Until httpStatus = 200 Or httpStatus > 500 Or httpStatus = 404  Or httpStatus = 0
        If httpStatus = 200 Then
            GetHTTP = Left$(httpObject.responseText,16000)
        Else
            GetHTTP = ""
        End If
    End Function


    Public Function GetFile(httpURL As String, filename As String) As Boolean
        Dim session As New NotesSession
        Dim retries As Integer
        Dim stream As NotesStream
        Dim flag As Boolean
        Dim responsebody As variant
        Dim cnt As Long
        Dim buffer As String
        Dim tmp As Byte

        Set stream = session.CreateStream
        retries = 0     
        Do
            If retries>1 Then
                Sleep 1     ' After the two first calls, introduce a 1 second delay betwen each additional call
            End If
            retries = retries + 1   
            Call httpObject.open("GET", httpURL, False)
            Call httpObject.send()
            httpStatus = httpObject.Status
            If retries >= 10 Then
                httpStatus = 0  ' Timeout
            End If
        Loop Until httpStatus = 200 Or httpStatus > 500 Or httpStatus = 404  Or httpStatus = 0
        If httpStatus = 200 Then
            flag = stream.Open(filename, "binary")
            If flag = False Then
                MsgBox "Failed to create " & filename & "..."
                GetFile = False 
                Exit function
            End If
            responsebody = httpObject.ResponseBody
            ForAll r in responsebody
                tmp = r
                Call Stream.Write(Chr$(CInt(tmp)))
                cnt = cnt + 1
            End ForAll
            MsgBox cnt
            GetFile = True
        Else
            GetFile = False
        End If

    End Function

    Private Function getString(ByVal StringBin As string)
        Dim intCount As Long
        getString =""
        For intCount = 1 To LenB(StringBin)
            getString = getString & Chr( Asc(MidB(StringBin, intCount, 1)) )
        Next
    End Function

End Class

这样在Domino中Agent也可以用到异步了。B/S就不用这么麻烦，直接用Javascript或JQuery即可。
