本文所述为visual basic6.0的一个模块方法，是使用XMLHTTP实现Post与Get功能，虽然是一个老代码，但是可以替代Inet控件，实现数据通讯。很值得学习借鉴一下。

主要模块代码如下：

'=========================================================='| 模 块 名 | XMLHTTP'| 说 明 | 替代Inet控件，实现数据通讯'==========================================================Public Enum DataEnum ResponseText = 1 ResponseBody = 2End Enum Public Function GetData(ByVal Url As String, ByVal DataStic As DataEnum) As Variant On Error GoTo ERR: Dim XMLHTTP As Object Dim DataS As String Dim DataB() As Byte Set XMLHTTP = CreateObject("Microsoft.XMLHTTP") XMLHTTP.Open "get", Url, True XMLHTTP.send While XMLHTTP.ReadyState <> 4 DoEvents Wend '--------------------------------------函数返回 Select Case DataStic Case ResponseText '--------------------------------直接返回字符串 DataS = XMLHTTP.ResponseText GetData = DataS Case ResponseBody '--------------------------------直接返回二进制 DataB = XMLHTTP.ResponseBody GetData = DataB Case ResponseBody + ResponseText '------------------------------二进制转字符串[直接返回字串出现乱码时尝试] DataS = BytesToStr(XMLHTTP.ResponseBody) GetData = DataS Case Else '--------------------------------无效的返回 GetData = "" End Select '--------------------------------------释放空间 Set XMLHTTP = Nothing Exit FunctionERR: GetData = ""End Function Public Function PostData(ByVal StrUrl As String, ByVal StrData As String, ByVal DataStic As DataEnum) As Variant On Error GoTo ERR: Dim XMLHTTP As Object Dim DataS As String Dim DataB() As Byte Set XMLHTTP = CreateObject("Microsoft.XMLHTTP") XMLHTTP.Open "POST", StrUrl, True XMLHTTP.setRequestHeader "Content-Length", Len(PostData) XMLHTTP.setRequestHeader "CONTENT-TYPE", "application/x-www-form-urlencoded" XMLHTTP.send (StrData) Do Until XMLHTTP.ReadyState = 4 DoEvents Loop '-----------------------------函数返回 Select Case DataStic Case ResponseText '--------------------------------直接返回字符串 DataS = XMLHTTP.ResponseText PostData = DataS Case ResponseBody '--------------------------------直接返回二进制 DataB = XMLHTTP.ResponseBody PostData = DataB Case ResponseBody + ResponseText '---------------------------二进制转字符串[直接返回字串出现乱码时尝试] DataS = BytesToStr(XMLHTTP.ResponseBody) PostData = DataS Case Else '--------------------------------无效的返回 PostData = "" End Select '------------------------------------释放空间 Set XMLHTTP = Nothing Exit FunctionERR: PostData = ""End Function Function BytesToStr(ByVal vIn) As String strReturn = "" For i = 1 To LenB(vIn) ThisCharCode = AscB(MidB(vIn, i, 1)) If ThisCharCode < &H80 Then strReturn = strReturn & Chr(ThisCharCode) Else NextCharCode = AscB(MidB(vIn, i + 1, 1)) strReturn = strReturn & Chr(CLng(ThisCharCode) * &H100 + CInt(NextCharCode)) i = i + 1 End If Next BytesToStr = strReturnEnd Function
