php - vb.net から xml を php ファイルに送信する

Question

PHPでキャッチできるvb.netからxmlファイルを送信するには$HTTP_ROW_POST?

私のスクリプトは次のとおりです。

Public Function PHP(ByVal url As String, ByVal method As String, ByVal data As String)

    Try

        Dim request As System.Net.WebRequest = System.Net.WebRequest.Create(url)
        request.Method = method
        Dim postData = data
        Dim byteArray As Byte() = Encoding.UTF8.GetBytes(postData)
        request.ContentType = "application/x-www-form-urlencoded"
        request.ContentLength = byteArray.Length
        Dim dataStream As Stream = request.GetRequestStream()
        dataStream.Write(byteArray, 0, byteArray.Length)
        dataStream.Close()
        Dim response As WebResponse = request.GetResponse()
        dataStream = response.GetResponseStream()
        Dim reader As New StreamReader(dataStream)
        Dim responseFromServer As String = reader.ReadToEnd()
        reader.Close()
        dataStream.Close()
        response.Close()
        Return (responseFromServer)
    Catch ex As Exception
        Dim error1 As String = ErrorToString()
        If error1 = "Invalid URI: The format of the URI could not be determined." Then
            MsgBox("ERROR! Must have HTTP:// before the URL.")
        Else
            MsgBox(error1)
        End If
        Return ("ERROR")
    End Try
End Function

しかし、を使用して PHP ファイルにキャプチャすることはできません$HTTP_ROW_POST。
