Cannot send a content-body with this verb-type

[groads2]

I am learning web services and want to get this client working. I get the error "Cannot send a content-body with this verb-type" You can see I have set the method to "POST". The error comes when I try to execute the line with ws.getRequestStream. Any Ideas? Thanks.

 

Public Class Form1

 

Dim myUrl As String = "http://www.webserviceX.net"

Dim ws As System.Net.HttpWebRequest = System.Net.WebRequest.Create(myUrl)

 

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click

 

Try

ws.Host = "www.webserviceX.net"

ws.Method = "POST"

ws.Timeout = 60000

ws.Accept = "text/xml"

ws.Headers.Add("SOAPAction", "http://www.webserviceX.NET/GetBookTitles")

' ws.ClientCertificates.Add

ws.ContentType = "text/xml; charset=""utf-8"""

 

Dim myxml As String = "<?xml version=""1.0"" encoding=""UTF-8""?>" & System.Environment.NewLine & _

"<soap:Envelope xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/"">" & System.Environment.NewLine & _

"<soap:Body>" & System.Environment.NewLine & _

"<GetBookTitles xmlns=""http://www.webserviceX.NET"">" & System.Environment.NewLine & _

"</soap:Body>" & System.Environment.NewLine & _

"</soap:Envelope>"

Dim myencoder As New System.Text.ASCIIEncoding()

Dim myxmlByteArray() As Byte = myencoder.GetBytes(myxml)

ws.ContentLength = myxmlByteArray.Length

 

Dim postquerystream As System.IO.Stream = ws.GetRequestStream()

postquerystream.Write(myxmlByteArray, 0, myxmlByteArray.Length)

postquerystream.Close()

Dim response As System.Net.HttpWebResponse = ws.GetResponse()

If response.StatusCode = System.Net.HttpStatusCode.OK Then

Dim respstream As System.IO.StreamReader = New IO.StreamReader(ws.GetRequestStream())

Dim responsedata As String = respstream.ReadToEnd()

Me.TextBox1.Text = responsedata

End If

response.Close()

Catch ex As Exception

Dim x As String = ex.ToString

End Try

End Sub

End Class

I have corrected this error by changing getRequestStream to getResponseStream but have a new problem. This the http header being sent.

 

POST / HTTP/1.1

Accept: text/xml

SOAPAction: http://www.webserviceX.NET/GetBookTitles

Content-Type: text/xml; charset="utf-8"

Host: http://www.webservicex.net

Content-Length: 207

Expect: 100-continue

Connection: Keep-Alive

 

The request line is not correct. My method is not showing in for the post. I am not sure how to get it there with httpWebRequest
