Http Post request through Httpwebrequest To forum RRS feed

  • Question

  • Hi.. sorry for my english but i'm italian... I'm creating an app that edit a post in a ipforum with httpwebrequest and httpwebresponse in vb.net... I use fiddler2 to get the post forms... I successfully create  the code to connect to the site... the authentication works well and i don't found problems... But to edit a post i don't find how to do it...
     this is the request of the site taken from fiddler:


    POST http://site.com/download/index.php?&app=forums&module=ajax&section=topics&do=editBoxSave&p=499632&t=103273&f=129 HTTP/1.1

    I write this code to do the webrequest:


            request1 = CType(WebRequest.Create("http://site.com/download/index.php?&app=forums&module=ajax" & _ 
            "&section=topics&do=editBoxSave&p=" & npost & "&t=" & ntopic & "&f=129"), HttpWebRequest)
            s = "md5check=d45d8f6f7a9aa4d1b0a169b7e4efdb6a&Post=Aggiunto%2520video%" _
            request1.Method = WebRequestMethods.Http.Post
            request1.ContentType = "application/x-www-form-urlencoded"
            Dim data = System.Text.Encoding.UTF8.GetBytes(s)
            request1.ContentLength = data.Length
            Dim str As IO.Stream = request1.GetRequestStream
            str.Write(data, 0, data.Length)
            request1.KeepAlive = True
            request1.CookieContainer = c
            request1.UserAgent = "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0; SLCC2; .NET CLR 2.0.50727;" & _"
            ".NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; InfoPath.2; OfficeLiveConnector.1.4; OfficeLivePatch.1.3)"
                response1 = request1.GetResponse
            Catch webex As Net.WebException
                Exit Sub
            Catch ex As Exception
                Exit Sub
            End Try
            If response1.StatusCode = HttpStatusCode.OK Then
                tmp = (New IO.StreamReader(response1.GetResponseStream())).ReadToEnd
                Dim fw As New IO.StreamWriter("D:\Desktop\z.htm", False)
                MsgBox("Problemi di connessione al sito...")
                Exit Sub
            End If

    naturally in c (a cookiecontainer) contains the cookies of the successful login.. did you see what is the problem? because i can't understand what is it :(
