基本身份验证网页登录VB.NET

Question

• 大家好，我有一个问题，试图自动化我们的UPS安装。网页使用基本身份验证，并在加载页面时提示登录。我们无法访问注册表以在IE中启用此功能，因为它已被禁用。我曾尝试使用httpweb请求和响应来提取cookie，但它似乎从未发送回一个。我的逻辑是将cookie用于网络浏览器控件，这样它就不会要求登录。这是我的代码，我有：

  Dim request As HttpWebRequest = DirectCast(WebRequest.Create("http://10.106.206.249"), HttpWebRequest)
  Dim mycache = New CredentialCache()
  mycache.Add(New Uri("http://10.106.206.249"), "Basic", New NetworkCredential("User", "Pass"))
  request.Credentials = mycache
  request.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.14) Gecko/20080404 Firefox/2.0.0.14"
  request.CookieContainer = New CookieContainer()
  Dim response As HttpWebResponse = CType(request.GetResponse(), HttpWebResponse)
  Dim cook As Cookie
  For Each cook In response.Cookies
      Console.WriteLine("Cookie:")
      Console.WriteLine("{0} = {1}", cook.Name, cook.Value)
      Console.WriteLine("Domain: {0}", cook.Domain)
      Console.WriteLine("Path: {0}", cook.Path)
      Console.WriteLine("Port: {0}", cook.Port)
      Console.WriteLine("Secure: {0}", cook.Secure)
      Console.WriteLine("When issued: {0}", cook.TimeStamp)
      Console.WriteLine("Expires: {0} (expired? {1})", cook.Expires, cook.Expired)
      Console.WriteLine("Don't save: {0}", cook.Discard)
      Console.WriteLine("Comment: {0}", cook.Comment)
      Console.WriteLine("Uri for comments: {0}", cook.CommentUri)
      Console.WriteLine("Version: RFC {0}", IIf(cook.Version = 1, "2109", "2965"))
      ' Show the string representation of the cookie.
      Console.WriteLine("String: {0}", cook.ToString())
  Next cook
  

我知道这在一定程度上是有效的，因为如果我使用了不正确的信用，我会抛出一个未授权的错误。因此，看起来要么我没有收到饼干，要么一个没有被发送。

我尝试过的另一种方法是用普通的Web发送一个标题。导航，但它的行为就像加载页面并提示登录：

    Dim authData
    Dim authHeader As String
    authData = System.Text.UnicodeEncoding.UTF8.GetBytes("User:Pass")
    authHeader = "Authorization: Basic: " & System.Convert.ToBase64String(System.Text.Encoding.ASCII.GetBytes("User:Pass")) & Chr(13) & Chr(10)
    Web.Navigate("http://10.106.206.249", False, Nothing, authHeader)

有人知道我是不是做错了什么吗？

一个更简单的解决方案是：

Web.Navigate("http://Administrator:retail@10.106.206.249")

请注意，如果你的密码中有一个@sign，你必须对其进行UrlEncode。(我不能100%确定密码是否仍然有效(
