Q：如何针对ASP网页调用XMLHTTP查询数据？
A：以下是其中一个范例：

Sub xyf()
Dim oXmlHttp As Object, ohtml As Object, obj1, obj2, obj3
Dim sVS As String, sEV As String, sstr As String
Dim iPage As Integer, TPage As Integer
Set oXmlHttp = CreateObject("msxml2.xmlhttp")
With oXmlHttp
.Open "GET", "http://www.drugfuture.com/cndrug/search.aspx?SearchTerm=" & xyf_Escape("阿莫西林") & "&DataFieldSelected=auto", False
.send
Set ohtml = CreateObject("htmlfile")
ohtml.body.innerhtml = .responsetext
' ohtml.body.innerhtml = VBA.StrConv(.responseBody, vbUnicode)
sVS = ohtml.getElementById("__VIEWSTATE").Value
sEV = ohtml.getElementById("__EVENTVALIDATION").Value
TPage = ohtml.getElementById("ResultNational").getElementsbytagname("span")(0).innertext
Set obj1 = ohtml.getElementById("GridViewNational")
Set obj2 = obj1.Rows
For i = 0 To obj2.Length - 2
Set obj3 = obj2(i).Cells
For j = 0 To obj3.Length - 1
Cells(k + 1, j + 1) = obj3(j).innertext
Next
k = k + 1
Next
For iPage = 2 To Round(TPage \ 30)
sstr = "__EVENTTARGET=GridViewNational&__EVENTARGUMENT=Page" & xyf_Escape("$" & iPage) & "&__LASTFOCUS=&__VIEWSTATE=" & xyf_EncodeURI(sVS) & "&__EVENTVALIDATION=" & xyf_EncodeURI(sEV)
With oXmlHttp
.Open "POST", "http://www.drugfuture.com/cndrug/search.aspx?SearchTerm=" & xyf_Escape("阿莫西林") & "&DataFieldSelected=auto", False
.SetRequestHeader "Content-Type", "application/x-www-form-urlencoded"
.send (sstr)
ohtml.body.innerhtml = .responsetext
sVS = ohtml.getElementById("__VIEWSTATE").Value
sEV = ohtml.getElementById("__EVENTVALIDATION").Value
' ohtml.body.innerhtml = VBA.StrConv(.responseBody, vbUnicode)
Set obj1 = ohtml.getElementById("GridViewNational")
Set obj2 = obj1.Rows
For i = 1 To obj2.Length - 2
Set obj3 = obj2(i).Cells
For j = 0 To obj3.Length - 1
Cells(k + 1, j + 1) = obj3(j).innertext
Next
k = k + 1
Next
End With
Next
End With
End Sub
Function xyf_EncodeURI(str)
Dim obj
Set obj = CreateObject("ScriptControl")
With obj
.Language = "JavaScript"
xyf_EncodeURI = .Eval("encodeURIComponent(""" & str & """)")
End With
Set obj = Nothing
End Function
Function xyf_Escape(str)
Dim obj
Set obj = CreateObject("ScriptControl")
With obj
.Language = "JavaScript"
xyf_Escape = .Eval("escape(""" & str & """)")
End With
Set obj = Nothing
End Function
