[2008] Navigating webpages

[graham23s]

Hi Guys,

I have tweaked my code and am able to login great to my website, but i'm not sure in regards to exactly hand how to navigate to anothe rpage once logged in

code:

            'Make a request for the desired web page
            Dim varRequest As HttpWebRequest = CType(WebRequest.Create("http://www.XXXX.com/login.html"), HttpWebRequest)
            Dim cookie As New CookieContainer
            Dim varCookieContainer As New Net.CookieContainer
            Dim varPostData As String = "username=graham23s&password=XXXXXXXX&remember=1&submit=Submit"
            Dim varBytes As Byte() = System.Text.Encoding.UTF8.GetBytes(varPostData)

            varRequest.Method = "POST"
            varRequest.KeepAlive = True
            varRequest.AllowAutoRedirect = True
            varRequest.ContentType = "application/x-www-form-urlencoded"
            varRequest.ContentLength = varBytes.Length
            varRequest.CookieContainer = varCookieContainer

            Dim varStream = varRequest.GetRequestStream()
            varStream.Write(varBytes, 0, varBytes.Length)
            varStream.Close()

            Dim varRequest2 As HttpWebRequest = CType(WebRequest.Create("http://www.XXXX.com/bm_edit.html"), HttpWebRequest)
            Dim cookie2 As New CookieContainer
            Dim varCookieContainer2 As New Net.CookieContainer
            Dim varPostData2 As String = "username=graham23s&password=XXXXXXXX&remember=1&submit=Submit"
            Dim varBytes2 As Byte() = System.Text.Encoding.UTF8.GetBytes(varPostData)



            Dim response As HttpWebResponse = CType(varRequest.GetResponse(), HttpWebResponse)
            Dim sr As New System.IO.StreamReader(response.GetResponseStream)
            Dim HTMLResponse As String = Trim(sr.ReadToEnd())

            'Display the html source code
            debugTextBox.Text = HTMLResponse
            response.Close()
            sr.Close()

do i make another request once logged in? or will that lose the session/cookies?

thanks for any help guys

Depends on how your website works, but if you use the same cookie container across your calls, that might work for you.

Hi N,

Yeah it uses cookies

this code:

            'Make a request for the desired web page
            Dim varRequest As HttpWebRequest = CType(WebRequest.Create("http://www.XXXXXXXX.com/login.html"), HttpWebRequest)
            Dim cookie As New CookieContainer
            Dim varCookieContainer As New Net.CookieContainer
            Dim varPostData As String = "username=graham23s&password=XXXXXXXX&remember=1&submit=Submit"
            Dim varBytes As Byte() = System.Text.Encoding.UTF8.GetBytes(varPostData)

            varRequest.Method = "POST"
            varRequest.KeepAlive = True
            varRequest.AllowAutoRedirect = True
            varRequest.ContentType = "application/x-www-form-urlencoded"
            varRequest.ContentLength = varBytes.Length
            varRequest.CookieContainer = varCookieContainer

            Dim varStream = varRequest.GetRequestStream()
            varStream.Write(varBytes, 0, varBytes.Length)
            varStream.Close()

Logs me in great, it's where exactly to add the request for the second page i'm kinda stuck on

code:

            'Make a request for the desired web page
            Dim varRequest As HttpWebRequest = CType(WebRequest.Create("http://www.XXXXXXXX.com/login.html"), HttpWebRequest)
            Dim cookie As New CookieContainer
            Dim varCookieContainer As New Net.CookieContainer
            Dim varPostData As String = "username=graham23s&password=XXXXXXXX&remember=1&submit=Submit"
            Dim varBytes As Byte() = System.Text.Encoding.UTF8.GetBytes(varPostData)

            varRequest.Method = "POST"
            varRequest.KeepAlive = True
            varRequest.AllowAutoRedirect = True
            varRequest.ContentType = "application/x-www-form-urlencoded"
            varRequest.ContentLength = varBytes.Length
            varRequest.CookieContainer = varCookieContainer

            Dim varStream = varRequest.GetRequestStream()
            varStream.Write(varBytes, 0, varBytes.Length)
            varStream.Close()

would i just add another:

Dim varRequest As HttpWebRequest = CType(WebRequest.Create("http://www.XXXXXXXX.com/anotherpage.html"), HttpWebRequest)

after this part or is there a bit more coding involved lol

varRequest.CookieContainer = varCookieContainer


Thanks mate

Just make a new web request, but use the same cookie container that you used for the initial request.

Thank N will do, appreciate the guidance
