如何登录窗口授权 [英] How to login window authorisation

问题描述

我有来自我的本地网站的HMTL代码我正在使用此代码

  //  我们将使用WebClient类来读取网页的HTML  
 WebClient MyWebClient =  new  WebClient（）; 
 
  //  读取网页HTML到字节数组 
 < span class =code-sdkkeyword> Byte  [] PageHTMLBytes; 
  if （textBox1.Text！=   ）
 {
 
 PageHTMLBytes = MyWebClient.DownloadData（textBox1.Text）; 
 
  //  将结果从字节数组转换为字符串 
 < span class =code-comment> //  并在TextBox中显示txtPageHTML  
 UTF8Encoding oUTF8 =  new  UTF8Encoding（）; 
 richTextBox1.Text = oUTF8.GetString（PageHTMLBytes）; 
}

解决方案

如果目标页面使用Windows身份验证，则很容易：

  //  我们将使用WebClient类来阅读网页的HTML  
 WebClient MyWebClient =  new  WebClient（）; 
 MyWebClient.Credentials =  new  NetworkCredential（  myusername，  mypassword）; 
 
  //  读取网页HTML到字节数组 
 < span class =code-sdkkeyword> Byte  [] PageHTMLBytes; 
 ... 

这会将Windows凭据添加到身份验证标题中。



如果使用其他身份验证机制，则需要以不同方式提供凭据。表格认证的一个很好的例子可以在以下网址找到：

I have probelem guys i am taking HMTL code from my local Site i am using this code

         // We'll use WebClient class for reading HTML of web page
WebClient MyWebClient = new WebClient();

// Read web page HTML to byte array
Byte[] PageHTMLBytes;
if (textBox1.Text != "")
{

  PageHTMLBytes = MyWebClient.DownloadData(textBox1.Text);

  // Convert result from byte array to string
  // and display it in TextBox txtPageHTML
  UTF8Encoding oUTF8 = new UTF8Encoding();
  richTextBox1.Text = oUTF8.GetString(PageHTMLBytes);
}

解决方案

If the target page is using Windows authentication it's easy:

         // We'll use WebClient class for reading HTML of web page
WebClient MyWebClient = new WebClient();
MyWebClient.Credentials = new NetworkCredential("myusername","mypassword");
 
// Read web page HTML to byte array
Byte[] PageHTMLBytes;
...

This will add the windows credentials into the authentication header.

If a different authentication mechanism is being used, you will need to provide the credentials in a different way. A really good example for forms authentication can be found at:
