直接上干货 

 Private Function POST(ByVal URL$, ByVal data$)
        Dim http
        On Error Resume Next
        http = CreateObject("WinHttp.WinHttpRequest.5.1")
        With http
            .Open("POST", URL, True)
            .setRequestHeader("Accept-Language", "zh-CN")
            .setRequestHeader("Cache-Control", "no-cache")
            .setRequestHeader("User-Agent", "Mozilla/4.0")
            .setRequestHeader("Connection", "Keep-Alive")
            .setRequestHeader("Content-Length", data.Length)
            .setRequestHeader("Content-Type", "application/x-www-form-urlencoded")
            .Send(data)
            .WaitForResponse()
            POST = .getallresponseheaders
            Dim request = http.responseText 
        End With
        http = Nothing
    End Function
