Hi
I am writing a VB .Net Exe which requires to send XML data to an ASP url and catch the response (which will also be in XML format).

The following is my snippet (which doesn't work):

VB

Try
    With xmlDoc
        xmlRoot = .CreateElement("TXN")
        xmlRoot.AppendChild(.CreateElement("HDR"))
        xmlRoot.SelectSingleNode("HDR").AppendChild(.CreateElement("ID"))
        xmlRoot.SelectSingleNode("HDR").SelectSingleNode("ID").AppendChild(.CreateTextNode("ABCDE"))
        .AppendChild(xmlRoot)
    End With
    data = System.Text.Encoding.UTF8.GetBytes(xmlDoc.OuterXml)
    sData = New System.Text.UTF8Encoding().GetString(data)
    wr = System.Net.WebRequest.Create(url)
    wr.Method = "GET"
    wr.ContentLength = Len(sData)
    rs = wr.GetRequestStream()
    rs.Write(data, 0, data.Length)
    rs.Close()
    wr2 = wr.GetResponse()
    sr = wr2.GetResponseStream()
    sr2 = New System.IO.StreamReader(sr)
    Me.TextBox1.Text = Me.TextBox1.Text & sr2.ReadToEnd
Catch x As Exception
    Me.TextBox1.Text = Me.TextBox1.Text & x.Message.ToString() & vbCrLf
End Try

The error is thrown at the line: rs.Write(data, 0, data.Length)
It says that content body cannot be sent with this verb type.

I need to make this work within a couple of days. Any help would be greatly appreciated.

Solution 1

Can you try method = "POST" instead of "GET"

VB

wr = System.Net.WebRequest.Create(url)
wr.Method = "POST"
wr.ContentLength = Len(sData)

That's not an option. The server expects the XML data in the query string.

This answer sounds like a right idea, my 5.

@Member 4291906: what do you mean "not an option"? How is you XML data or what ever related to the request type. This is just a fix of your bug. If you ***send*** data, it's POST. You say "send XML" data and not sending it. How to understand you?
