问题描述
当我使用#NAME吗?有时#value,可能是什么原因请指导
谢谢
Public Function disTANCE(start As String,dest As String,key As String)
Dim firstVal As String,secondVal As String,lastVal As String
firstVal = "http://dev.virtualearth.net/REST/V1/Routes/Driving?wp.0="
secondVal = "&wp.1=destinations="
lastVal = "&optimize=time&routePathOutput=Points&distanceUnit=km&output=xml&key=" & key
Set objHTTP = CreateObject("MSXML2.ServerXMLHTTP")
URL = firstVal & start & secondVal & dest & lastVal
objHTTP.Open "GET",URL,False
objHTTP.SetRequestHeader "User-Agent","Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)"
objHTTP.Send ("")
disTANCE = Round(Round(WorksheetFunction.FilterXML(objHTTP.ResponseText,"//Traveldistance"),3) * 1.609,0)
End Function
解决方法
三件事。
-
您需要将小写字母与州和州之间的2个字母缩写传递给对方
-
上面的内容需要使用Urlencoded
-
响应具有您需要添加的默认名称空间。对于后者,我求助于使用MSXML2.DOMDocument以便添加名称空间。
Public Sub test()
Debug.Print GetDistance("new york,ny","miami,fl","key")
End Sub
Public Function GetDistance(ByVal start As String,ByVal dest As String,ByVal key As String) As Long
Dim firstVal As String,secondVal As String,lastVal As String,objHTTP As Object,url As String
firstVal = "http://dev.virtualearth.net/REST/V1/Routes/Driving?wp.0="
secondVal = "&wp.1=destinations="
lastVal = "&optmz=time&routePathOutput=Points&distanceUnit=km&output=xml&key=" & key
Set objHTTP = CreateObject("MSXML2.ServerXMLHTTP")
url = firstVal & Application.EncodeURL(LCase$(start)) & secondVal & Application.EncodeURL(LCase$(dest)) & lastVal
objHTTP.Open "GET",url,False
objHTTP.setRequestHeader "User-Agent","Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)"
objHTTP.send
Dim xmlDoc As MSXML2.DOMDocument60 'reference to Microsoft XML via VBE>Tools>References
Set xmlDoc = New MSXML2.DOMDocument60
xmlDoc.LoadXML objHTTP.responseText
xmlDoc.SetProperty "SelectionNamespaces","xmlns:r='http://schemas.microsoft.com/search/local/ws/rest/v1'"
GetDistance = Round(Round(xmlDoc.SelectSingleNode("//r:TravelDistance").Text,3) * 1.609,0)
End Function
