Instagram Register HttpWebRegister - vb.net

Question

I want to make a method to create an Instagram, but I can't to figure out how to get the cookie automatically
My old method :
Function register()
Dim postData As String = "email=" & EmailBox.Text + "#gmail.com" & "&password=" & PassBox.Text & "&username=" & UserBox.Text & "&first_name=" & NameBox.Text
Dim encoding As New UTF8Encoding
Dim byteData As Byte() = encoding.GetBytes(postData)
Dim request As HttpWebRequest = DirectCast(WebRequest.Create("https://www.instagram.com/accounts/web_create_ajax/"), HttpWebRequest)
request.Method = "POST"
request.KeepAlive = True
request.Headers.Add("X-CSRFToken", "q4NBIiEDDiPwGliNk6xxxxW9IooCHm")
request.ContentType = "application/x-www-form-urlencoded"
request.Headers.Add("X-Instagram-AJAX", "1")
request.Headers.Add("X-Requested-With", "XMLHttpRequest")
request.Headers.Add("Cookie", "mid=WZWf8QALxxxxcWsM-P1hm5F; csrftoken=q4NBIiEDDixxxxZrW9IooCHm; rur=FTW; ig_vw=16; ig_pr=1; ig_vh=4")
request.Referer = "https://www.instagram.com/"
request.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:40.0) Gecko/20100101 Firefox/40.1"
request.ContentLength = byteData.Length
Dim requestStream As Stream = request.GetRequestStream()
requestStream.Write(byteData, 0, byteData.Length)
requestStream.Close()
Dim responseS As HttpWebResponse
responseS = DirectCast(request.GetResponse(), HttpWebResponse)
Dim Reader As New StreamReader(responseS.GetResponseStream())
Dim thepage As String = Reader.ReadToEnd
If thepage.Contains("This username isn't available. Please try another") Then
Label6.ForeColor = Color.DarkRed
Label6.Text = UserBox.Text + "Has been fail register !!"
Else
Label6.ForeColor = Color.LightGreen
Label6.Text = UserBox.Text + "Has been successfully register !!"
End If
TextBox1.Text = thepage
End Function
How can I get the cookie automatically?

Answer 1

there you go. This is an sample for login in to ASP.NET MVC website. Look for Cookiejar to retreive them.
Dim tclient As HttpClient
Dim cookiejar As New CookieContainer
cookiejar = handler.CookieContainer
Dim xResponse As HttpResponseMessage = Await (tclient.GetAsync(BaseAddress & LoginUrl))
Dim xcookies As CookieCollection = cookiejar.GetCookies(New Uri(BaseAddress & LoginUrl))
For Each tCookie As Cookie In xcookies
If tCookie.Name = "__RequestVerificationToken" Then vCookie = tCookie : VerificationToken = tCookie.Value : Exit For
Next
Dim body As String = Await (xResponse.Content.ReadAsStringAsync())
Dim htdoc As New HtmlAgilityPack.HtmlDocument
htdoc.LoadHtml(body)
Dim xxdoc As HtmlNode = htdoc.GetElementbyId("loginform")
For Each xnodes As HtmlNode In xxdoc.Elements("input")
If xnodes.Attributes(0).Value = "__RequestVerificationToken" Then
FormValidationToken = xnodes.Attributes(2).Value
End If
Next
